Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular, to a pollution rights trading method, system, and electronic device. Background Art

[0002] Pollution rights, also known as emission rights, are the rights to emit pollutants. It refers to the rights that emitters enjoy to emit pollutants into the environment within the quota allocated by the environmental protection supervision and management department and on the premise of ensuring that the exercise of this right does not damage the environmental rights and interests of other members of the public.

[0003] Pollution rights trading refers to a situation within a certain region where, on the premise that the total amount of pollutant emissions does not exceed the allowable emissions, internal pollution sources adjust their emission volumes through monetary exchanges with each other, thereby achieving the goal of reducing pollution and protecting the environment. As a market-based economic system arrangement, the economic incentive for enterprises in pollution rights trading is that the seller of pollution rights has surplus pollution rights due to excessive emission reduction, and then obtains economic returns by selling or leasing the surplus pollution rights. This is essentially the market's compensation for enterprises' environmental protection behaviors. The buyer or lessee has to pay a price due to newly added pollution rights, and the expenses they pay are essentially the price of environmental pollution.

[0004] Each enterprise user can conduct subscription, listing, transaction approval, etc. on the pollution rights trading platform. Pollution rights trading also involves many aspects, such as tax payment. In the prior art, after enterprise users reach a transaction intention, they need to pay taxes offline and then upload them to the pollution rights trading platform. Summary of the Invention

DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0017] It should be noted that in cases where the embodiments of this application involve user information, the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the embodiments of this application are all information and data that have been authorized by the user or fully authorized by all parties. Additionally, the collection, use, and processing of relevant data need to comply with relevant laws, regulations, and standards of relevant countries and regions, and corresponding operation entrances are provided for users to choose to authorize or reject. Moreover, various models (including but not limited to language models or large models) involved in this application comply with relevant laws and standards.

[0018] In addition, it should be noted that in cases where the embodiments of this application involve user interaction operations or trigger operations, the user interaction operations or trigger operations involved in the embodiments of this application include but are not limited to: interaction operations in various ways such as touch operations, gesture operations, voice operations, head movement operations, eye movement operations, etc.; among them, touch operations include but are not limited to: click operations, double-click operations, long-press operations, swipe operations, pinch operations, or mouse hover operations, etc. Swipe operations include but are not limited to: straight-line swipes, curved swipes, etc.

[0019] Furthermore, in cases where the embodiments of this application involve jumps between interfaces, the jump methods involved in the embodiments of this application include but are not limited to: directly jumping from the first interface to the second interface, or first jumping from the first interface to a task interface and then jumping to the second interface when corresponding task operations are completed on the task interface.

[0020] The artificial intelligence tools mentioned in the embodiments of this application can be specifically implemented as machine learning models (such as neural network models). Of course, the artificial intelligence tools can also be language parsing models based on artificial intelligence, and this language parsing model can be a language model (Language Model, LM) based on artificial intelligence. The embodiments of this application do not limit the quantity of model parameters supported by the language model, aiming to meet application requirements.

[0021] In addition, the trading volume of emission rights in the trading data mentioned herein has been audited by an organization (such as an environmental protection department or organization) and a surplus emission volume certificate has been obtained. Or it is the emission rights that can be sold reserved by an organization (such as an environmental protection department or organization).

[0022] In view of the problem of the existing multiple platforms being independent of each other, the embodiments of the present application provide a solution. The basic idea is: to connect multiple platforms. For example, connect the emission rights trading platform with the tax service platform. In this way, the emission rights trader can enter the tax service platform through the emission rights trading platform to pay taxes. After tax payment, without the operation of the taxpayer, the emission rights trading platform will automatically obtain the tax payment information. Of course, in addition to connecting the emission rights trading platform and the tax service platform, the financial open platform can also be connected with the emission rights trading platform, etc., to achieve the coordination of multiple platforms and intelligent full-link management.

[0023] The following will combine the accompanying drawings to detail the technical solutions provided by the embodiments of the present application.

[0024] Figure 1 It is a schematic structural diagram of an emission rights trading system provided by an exemplary embodiment of the present application. As Figure 1 shown, the system includes: a first server 1, a second server 2, a first client 3, and a second client 4. Among them, the first client and the second client are general references, and they represent the clients corresponding to all trading parties on the emission rights trading platform respectively.

[0025] The first server 1 provides an emission rights trading platform, and the emission rights trading includes transfer and lease; the first server 1 is used to determine the transaction data in the emission rights trading, the identifier of the transferor who reaches the transaction intention, and the identifier of the transferee; based on the identifier of the transferee and the transaction data, generate the platform service fee corresponding to the transferee; send the platform service fee to the second client corresponding to the transferee according to the identifier of the transferee, so that the transferee can perform the payment operation through the second client; if the emission rights trading is not an agreement transfer, then in response to the indication that the first client and the second client corresponding to the transferor have uploaded the transaction contract, determine the tax information corresponding to the transferee based on the transaction data; send the tax information to the second client, so that the transferee can enter the tax service platform through the second client to perform the tax payment operation; after determining that the transferee has successfully paid the platform service fee and receiving the tax payment information of the transferee feedback by the tax service platform, perform the transfer operation of the emission rights corresponding to the transaction data to transfer the emission rights from the transferor to the transferee.

[0026] The second server 2 provides a tax service platform and is connected to the first server 1.

[0027] The first server 1 is further used to provide the function for the transferee corresponding to the second client 4 to enter the tax service platform through the emission rights trading platform to pay taxes, and can synchronize the tax payment information of the transferee with the tax service platform.

[0028] The second client 4 corresponds to the transferor in the emission rights trading. The second client 4 is used to display the platform service fee information sent by the first server corresponding to the emission rights trading platform on the trading page corresponding to the emission rights trading platform after the transferee and the transferor reach a trading intention; respond to the payment operation performed by the transferee on the trading interface and execute the platform service fee payment process; after the transferee successfully pays the platform service fee and the transferor and the transferee complete the signing of the trading contract through their respective clients, display the tax information sent by the first server on the trading page; the tax information is determined based on the trading data of the transferee in the emission rights trading; respond to the operation of the transferee on the trading interface for the tax information and jump to the tax payment page corresponding to the tax service platform so that the transferee can execute the tax payment operation according to the prompts on the tax payment page; after the transferee completes the tax payment, display the trading page, and the trading page displays the tax payment information of the transferee feedback by the tax service platform; receive and display the information indicating the successful transfer of the emission rights corresponding to the trading data feedback by the first server.

[0029] The first client 3 corresponds to the transferee in the emission rights trading. If the contract information is initiated by the transferor, the first client 3 is used to display the contract generation control on the trading page corresponding to the emission rights trading platform after the transferor and the transferee reach a trading intention and it is determined that the transferee has successfully paid the platform service fee; respond to the operation of the transferor on the contract generation control and display the artificial intelligence tool interaction page so that the transferor can trigger the artificial intelligence tool to generate contract information that meets the transferor's needs and is suitable for emission rights trading by communicating with the artificial intelligence tool on the interaction interface; respond to the confirmation instruction of the transferor for the contract information or the confirmation instruction after the transferor modifies and saves the contract information, and send the confirmed contract information to the second client 4 corresponding to the transferee so that the transferee can review, adjust and confirm; after the transferee and the transferor conduct at least one round of contract negotiation for the contract information through their respective corresponding clients, determine the target contract on which both parties reach an agreement; respond to the signing operation of the transferor on the target contract and send the target contract signed by the transferor to the first server 1, and the first server 1 sends the target contract to the second client 4 so that the transferee can sign.

[0030] Further, as Figure 1 shown, the system provided in this embodiment may further include: The third server 5 provides a financial open platform, which is used to obtain information from the first server 1 and publish it, or receive information pushed by the first server 1 and publish it.

[0031] Furthermore, the system provided in this embodiment may also be connected to other platforms, such as a third-party payment platform (providing real-time online payment), a bank service platform (providing real-time online payment), etc. This embodiment does not make specific limitations on this.

[0032] The following describes the information interaction among each server (corresponding to the platform) and the client (such as the assignee and the assignor) in the system provided in this embodiment in combination with specific scenarios.

[0033] Scenario 1: Transfer of organizational reserve The assignor is an organization (such as an environmental protection department or organization), and the assignee is an enterprise.

[0034] See Figure 2a and 2b As shown, the information interaction process among the second client of the enterprise, the first client of the organization, and the corresponding server of the emission rights trading platform includes: S11. The enterprise logs in to the second client application and submits the purchase application materials through the first client.

[0035] Among them, the purchase application materials may include but are not limited to the following: emission rights indicators (such as chemical oxygen demand, ammonia nitrogen, sulfur dioxide, or nitrogen oxides, etc.), purchase quantity, validity period, enterprise purchase qualification, etc.

[0036] S12. The first client can obtain the enterprise's purchase application materials by accessing the emission rights trading platform and approve them. If the approval is passed, the enterprise enters the enterprise buffer pool and waits for the organization to create a session, and enters step S13. Otherwise, the first server responds to the disapproval indication of the first client and sends a resubmission and approval notice to the first client.

[0037] S13. The first client creates a session and triggers the first server to release the session announcement so that all eligible enterprises in the enterprise buffer pool can learn about the session information through their respective second clients. The first server responds to the successful creation of the bidding session by the first client and sends a session notice to each corresponding second client of all eligible enterprises in the enterprise buffer pool.

[0038] After the first client creates a session, if there are enterprises to be removed in the enterprise buffer pool, a removal application can be submitted at this stage. If the superior supervisor agrees to remove, it will be removed; if not, the removal application needs to be resubmitted. After determining the eligible enterprises, confirm the session information and publicize it on the emission rights trading platform through the first server.

[0039] Of course, if the system provided in this embodiment also connects to the financial open platform, the first server can also send the session information to the third server to synchronously announce the session information on the financial open platform.

[0040] S14. After receiving the notice through the second client, the enterprise can complete online deposit through the second client and conduct online bidding within the validity period of the corresponding bidding session of the session information. The enterprise's bidding information is sent to the first server through the second client for the first client to know.

[0041] S15. The first server determines the auction result. When determining the auction result, it is necessary to determine whether there are defaulting enterprises and enterprises with invalid bids. If there are defaulting enterprises, the service fee shall be deducted from the margin and forfeited due to the default of the defaulting enterprise. If there are enterprises with invalid bids, an application for invalid bid approval shall be submitted to the superior competent organization or institution. If the superior competent organization or institution agrees, the enterprise shall be notified of the invalid bid and the insurance shall be withdrawn. If it does not agree, relevant departments or units shall re-determine whether it meets the requirements for an invalid bid.

[0042] In specific implementation, the auction result can also be confirmed by the session organizing unit. It should be noted here that the session organizing unit can be the organizational structure mentioned above (such as the environmental protection department or organization), or another organization or institution specifically responsible for session organization. For example, an organizational structure contains different departments, and each department has its own account with corresponding permissions to perform corresponding work (such as approval, verification of auction results, etc.) in a certain link of the entire pollutant discharge right trading process. The clients corresponding to these accounts can all be uniformly referred to as the first client. For example, the session organizing unit and the superior competent organization or institution mentioned above perform corresponding work in different links of the entire pollutant discharge right trading process. The session organizing unit creates the auction session and confirms the auction result; the superior competent organization or institution only participates in the review of the invalid bid link.

[0043] Similarly, the session organizing unit can also determine whether an enterprise is in default or has an invalid bid, and provide the determination result to the first server so that relevant information can be retained at the first server as filing information.

[0044] Of course, in specific implementation, the confirmation of the auction result, the review of defaulting and enterprises with invalid bids can also be achieved by the first server. For example, confirmation and review rules are deployed on the first server, and the first server can confirm the auction result and review defaulting and enterprises with invalid bids based on the pre-deployed rules, etc.

[0045] S16. After the first server confirms the final auction result, it announces the auction result on the pollutant discharge right trading platform and sends a notice of transaction and payment to the participating enterprises in the auction result.

[0046] Among them, the payment notice can be a notice to notify the successful enterprise to pay the platform service fee.

[0047] S17. After the enterprise receives the notice through the second client, it pays the platform service fee online, signs the contract and uploads it.

[0048] S18. The organizational structure party can obtain the contract signed by the enterprise from the first server through the first client and sign on the contract that can reach a consensus.

[0049] It should be supplemented here that the contract signed by the two trading parties can be drafted by either party. Of course, the emission rights trading platform provided in the embodiments of the present application, that is, the first server, has the function of automatically drafting contracts for the two trading parties, and the drafted contracts are applicable to emission rights trading. The two parties can adjust the drafted contracts online or offline to reach an agreement. For the agreed contract, one of the two parties can initiate the contract signing, and the other party can obtain the contract already signed by one party from the first server through the corresponding client, then sign their own signature, and click submit (or upload) through the corresponding client (such as an application) to complete the signing of the contract by both parties.

[0050] S19. The first server determines the target emission rights indicators and tax information, and sends a tax payment notice to the second client.

[0051] In specific implementation, the organization party can fill in the source of the emission rights indicators and tax information for this transaction through the first client. Of course, the first server can also calculate the tax information based on the transaction data (emission rights indicators, trading volume, etc.) of this transaction. Or, the first server sends the transaction data of this transaction and the enterprise identifier (i.e., the transferee identifier) to the tax service platform, and the third server calculates the tax information. The third server returns the tax information to the first server, and then the first server sends it to the second client.

[0052] S20. After receiving the tax payment notice, the enterprise enters the tax service platform through the second client and performs tax payment operations according to the tax payment process. The second server sends the enterprise's tax payment completion information to the first server, or the first server obtains the enterprise's tax payment completion information from the second server.

[0053] S21. After the first server determines that the enterprise has completed tax payment, it determines whether the enterprise has paid the platform service fee. If it has been paid, the indicator transfer is executed. The first server sends an indicator quantity transfer-in notice to the second client, and at the same time sends an indicator quantity transfer-out notice to the first client. In this way, the enterprise can view the indicator quantity credit notice, and the organization party can view the indicator quantity debit notice.

[0054] After the emission rights are transferred from the transferor to the transferee, the first server can update the emission rights information corresponding to the organization party (i.e., the transferor) and the emission rights information corresponding to the enterprise (i.e., the transferee) in the emission rights information management database; and trigger the emission rights tracking and early warning system to update the emission rights early warning benchmark corresponding to the transferor and the emission rights early warning benchmark corresponding to the transferee.

[0055] Scenario 2: Inter-enterprise transactions The transaction methods for transactions between enterprises include: transfer and lease. Transfer includes: listing transaction, auction transaction, and agreement transfer. Lease includes: agreement lease and listing lease. Among them, in a listing transaction, an enterprise lists for sale or purchase of pollution discharge rights on a pollution discharge rights trading platform, and the price is negotiated by the market. In an auction transaction, an organization (such as an environmental protection department or organization) or an exchange organizes a public auction. Agreement transfer is a direct negotiation and transaction between enterprises, which needs to be filed with the regulatory department.

[0056] This scenario is an agreement transfer or agreement lease between enterprises. In this scenario, there is a cross-city transaction. In this scenario, the client corresponding to the transferor is called the first client, and the client corresponding to the transferee is the second client. The transferor and the transferee can be different factories of the same enterprise, or two different enterprises, etc. Specifically, such as Figure 3a and 3b , including the following steps: S21. The transferor logs in through the first client, and then submits an agreement transfer or lease application to the first server through the first client.

[0057] Among them, the application may include but is not limited to: pollution discharge rights agreement transfer or lease indicators, indicator quantity, validity period, transferor's transferable qualifications, etc. Obtaining That is, for the transfer or lease of pollution discharge rights, approval is required. After approval, the relevant qualifications can be obtained.

[0058] S22. The transferee logs in through the second client, and then can obtain the agreement transfer or lease application submitted by the transferor from the first server through the second client. The transferee can supplement the application materials through the second client, such as supplementing the information of the area where the transferee is located, the relationship with the transferor, the qualifications to undertake the agreement transfer or lease, etc.

[0059] After the transferee completes the supplementation of the application materials through the second client, upload them to the first server for approval by the competent unit.

[0060] S23. The co-competent unit can obtain the application materials through the third client and approve them.

[0061] It should be added here that this scenario is a cross-city transaction. Assume that the transferor and the transferee are located in different cities but belong to the same province. Therefore, during the approval process, multi-level approval is required, which is not detailedly drawn in the attached drawings corresponding to this embodiment. Specifically, it may include: S231. The district or county-level competent unit under the city where the transferor is located obtains the application materials from the first server through its corresponding client and approves them.

[0062] S232. The district or county-level competent authority under the city where the transferee is located obtains the application materials from the first server through its corresponding client and approves them.

[0063] S233. After the application materials pass the approval of the district or county-level competent authority under the city where the transferor is located and the district or county-level competent authority under the city where the transferee is located, the two district or county-level competent authorities conduct the first-level joint signature.

[0064] S234. After the two district or county-level competent authorities complete the joint signature, the first server triggers the approval by the municipal-level competent authority where the transferor is located and triggers the approval by the municipal-level competent authority where the transferee is located.

[0065] S235. The municipal-level competent authority where the transferor is located obtains the application materials after the first-level joint signature from the first server through its corresponding client and conducts the approval.

[0066] S236. The municipal-level competent authority where the transferee is located obtains the application materials after the first-level joint signature from the first server through its corresponding client and conducts the approval.

[0067] S237. After the application materials pass the approval of the municipal-level competent authority where the transferor is located and the municipal-level competent authority where the transferee is located, the two municipal-level competent authorities conduct the second-level joint signature.

[0068] S238. After the two municipal-level competent authorities complete the joint signature, the first server triggers the approval by the common competent authority of the transferor and the transferee (i.e., the provincial-level competent authority).

[0069] As Figure 3a shown, the common competent authority of the transferor and the transferee obtains the application materials after the second-level joint signature from the first server through the third client and conducts the approval.

[0070] S24. After the approval by the common competent authority is passed, the first server responds to the approval passed instruction triggered by the third client and sends notifications to the transferor and the transferee respectively.

[0071] Specifically in implementation, the notifications can be sent by means of instant communication applications, text messages or emails.

[0072] S25. After receiving the notification, the transferor can select the session time and create a session on the pollutant discharge right trading platform through the first client. The first server responds to the event of creating a session by the first client and generates session announcement information for publication on the pollutant discharge right trading platform.

[0073] S26. After the transferee views the session announcement information through the second client, the transferee can pay the deposit online through the second client to participate in the transfer or lease session created by the transferor and make a bid.

[0074] After the transferee pays the deposit and wins the bid successfully, the first server determines the session result corresponding to the session created by the transferor for the session.

[0075] In an implementable solution, the first server determines the session result. When determining the session result, it is necessary to determine whether the transferee has any breach of contract and whether it is necessary to reject the bid, etc. After the above judgment, the final session result is confirmed and publicized.

[0076] In another implementable solution, the co-sponsoring unit determines the session result. When determining the session result, it is necessary to determine whether the transferee has any breach of contract and whether it is necessary to reject the bid, etc. After the above judgment, the co-sponsoring unit confirms the final session result through the third client and triggers the first server to publicize it.

[0077] If the transferee has any breach of contract, the first server sends a notice to the second client to notify the transferee to deduct the service fee from its deposit and confiscate it. If the transferee is in the situation of bid rejection, the transferee is notified of the bid rejection and the deposit is returned. If the transferee neither has any breach of contract nor is in the situation of bid rejection, the transferee can receive a notice of successful transaction confirmation.

[0078] S28. The transferee pays the platform service fee through the second client. The first server responds to the event that the transferee completes the payment of the platform service fee and triggers the transferor and the transferee to sign a contract.

[0079] Among them, either the transferor or the transferee can initiate the drafting of the contract. This embodiment does not make specific limitations on this. In the embodiment shown in the figure, the transferor initiates the contract signing. In specific implementation, it can be set that the contract can be signed only after the transferee pays the platform service fee.

[0080] S29. The transferor signs the contract through the first client and uploads it.

[0081] S210. The transferee can obtain the contract signed by the transferor from the first server through the second client and sign on the contract on which a consensus can be reached.

[0082] S211. The transferor uploads the receipt voucher through the first client.

[0083] It should be noted here that: if the contract can be signed only after the transferee completes the payment of the platform service fee, then the first server does not need to determine whether the transferee has paid the platform service fee. For example Figure 3bIn the shown example, when the system does not set the constraint that "the contract can only be signed after the transferee completes the payment of the platform service fee", the first server determines whether the transferee has paid the platform service fee. If so, it triggers the co-sponsoring unit to approve the vouchers uploaded by the transferor through the third client. After the approval, the co-sponsoring unit can determine again through the third client whether to cancel the bid. If not, the third client triggers the first server to refund the transferee's deposit and notifies the transferee that the insurance has been cancelled; if so, the third client triggers the first server to notify the transferee of the cancellation of the bid and refund the deposit, and synchronously modifies the public notice of the session result mentioned in step S16.

[0084] S212. The first server performs index transfer. The first server sends a notice of index quantity transfer-in to the second client and at the same time sends a notice of index quantity transfer-out to the first client. In this way, the transferee can view the notice of index quantity credit, and the transferor can view the notice of index quantity debit.

[0085] In the corresponding embodiment of this scenario, the emission rights are transferred or leased by agreement, and there is no tax payment. Therefore, the above steps do not involve tax payment content.

[0086] Scenario Three: Inter-enterprise Transactions This scenario is for enterprises to list for transfer, auction or list for lease, and there is a cross-city transaction situation in this scenario. In this scenario, the client corresponding to the transferor is called the first client, and the client corresponding to the transferee is the second client. The process of this scenario is similar to that in Scenario Two above. The difference lies in the specific implementation of steps S21, S22, S24, S25, S26 and S27 in this scenario.

[0087] In this scenario, S21' is specifically as follows: The transferor completes the login through the first client, and then submits an application for agreement transfer or lease to the first server through the first client. The district or county-level competent unit where the transferor belongs approves the application through the third client. After the approval, the transferor selects the session time and creates a session.

[0088] In the corresponding embodiment of this scenario, the transferor creates a session in S21. While in the corresponding embodiment of the above Scenario Two, the session is created in step S25.

[0089] S22' is specifically as follows: After the transferor creates a session, the first server issues a session announcement for this session (i.e., publishes it on the emission rights trading platform). After the transferee learns about the session created by the transferor through the second client, the transferee can sign up through the second client.

[0090] S23 is the same as the corresponding embodiment of Scenario Two above.

[0091] Specifically, S24’ is as follows: After the co-sponsoring unit approves, the first server responds to the approval instruction triggered by the third client and sends a notice to the assignee.

[0092] Specifically, S25’ is as follows: After receiving the notice, if the transferor is an auction, the assignee bids according to the auction rules (such as price priority, time priority, etc.).

[0093] Specifically, S26’ is as follows: After receiving the notice, if the transferor is a listed transfer or a listed lease, the assignee can pay the deposit and make an offer through the second client.

[0094] Specifically, S27’ is as follows: If the transferor is a listed transfer or a listed lease, after the assignee pays the deposit and successfully makes an offer, the first server determines the corresponding session result for the session created by the transferor. If the transferor is an auction and the assignee wins the bid, the first server determines the corresponding session result for the session created by the transferor.

[0095] S28~S212 are the same as the embodiments corresponding to the above scenario two.

[0096] The above embodiments introduce the content of the whole-link management of pollution rights trading from the perspective of the entire system. Next, the methods corresponding to each end will be described from different ends.

[0097] Such as Figure 4 shows a schematic flowchart of a pollution rights trading method provided by an embodiment of the present application. The method provided in this embodiment is applicable to the first server corresponding to the pollution rights trading platform. Specifically, as Figure 4 shown, the method includes: 101. Determine the transaction data in the pollution rights trading, the transferor identifier and the assignee identifier that have reached a transaction intention; 102. Generate the platform service fee corresponding to the assignee based on the assignee identifier and the transaction data; 103. Send the platform service fee to the second client corresponding to the assignee according to the assignee identifier, so that the assignee can perform a payment operation through the second client; 104. If the pollution rights trading is not a negotiated transfer, respond to the instruction that the first client corresponding to the transferor and the second client have uploaded the transaction contract, and determine the tax information corresponding to the assignee based on the transaction data; 105. Send the tax information to the second client, so that the assignee can enter the tax service platform through the second client and perform a tax payment operation; 106. After determining that the transferee has successfully paid the platform service fee and received the tax payment information of the transferee feedback by the tax service platform, perform the transfer operation of the emission rights corresponding to the transaction data to transfer the emission rights from the transferor to the transferee.

[0098] It should be noted here that: the transferor in this embodiment may be the organizational entity mentioned in the above embodiment (such as the environmental protection department / organization, etc.), and the transferee may be an enterprise. Of course, the transferor and the transferee may also be two different enterprises. The content of tax payment is not involved in the embodiments corresponding to Scenario 2 and Scenario 3 above, and the taxes and fees shall comply with the provisions of relevant laws and regulations. Whether taxes and fees need to be paid for the transaction of emission rights between enterprises is not limited in this embodiment.

[0099] The solution provided in this embodiment aims to: highlight the innovative technology of this application, that is, the multi-platform collaboration technology, and connect multiple platforms, such as the emission rights trading platform, the tax service platform, etc.

[0100] The technical solution provided in the embodiment of this application connects the emission rights trading platform and the tax service platform, that is, realizes the multi-platform collaboration solution. The transferee can directly enter the tax service platform on the emission rights trading platform to pay taxes, and the tax service platform will timely feedback the tax payment information of the transferee to the emission rights trading platform, so that the emission rights trading platform can timely transfer the emission rights corresponding to the transaction data of this time. Adopting the solution of the embodiment of this application, the transferee does not need to log in and operate on multiple platforms respectively, nor does it need to upload the tax payment information to the emission rights trading platform, or the emission rights trading platform does not need to verify whether the transferee has paid taxes. The whole process is efficient and helps to realize the full-link management of emission rights trading.

[0101] Further, when the transaction between the transferor and the transferee is an inter-regional transaction, the method provided in this embodiment may further include: Respond to the transfer application triggered by the transferor for the transaction data, and send a first approval notice to the first management party corresponding to the first region where the transferor belongs; Respond to the transfer application triggered by the transferee for the transaction data, and send a second approval notice to the second management party corresponding to the second region where the transferee belongs; After receiving the approval through instruction made by the first management party for the first approval notice and the approval through instruction made by the second management party for the second approval notice, send a third approval notice to the third management party corresponding to the superior region where the transferor and the transferee belong; After receiving the approval through instruction made by the third management party for the third approval notice, send a permission to trade notice to the transferor and the transferee.

[0102] For example, in the embodiments corresponding to Scenario 2 and Scenario 3 above, first, the district or county-level competent authority approves, then the city-level competent authority approves, and finally the provincial-level competent authority approves. If the transferor and the transferee are in the same city but belong to different districts or counties, only two approvals are required, that is, the district or county-level competent authority where each belongs approves, and then the city-level competent authority approves. The city-level competent authority is the joint competent authority.

[0103] Furthermore, the method provided by the embodiments of the present application may further include: 107. After the emission rights are transferred from the transferor to the transferee, update the emission rights information corresponding to the transferor and the emission rights information corresponding to the transferee in the emission rights information management database; 108. Trigger the emission rights tracking and early warning system to update the emission rights early warning benchmark corresponding to the transferor and the emission rights early warning benchmark corresponding to the transferee.

[0104] Among them, the emission rights tracking and early warning system is used to track the emission behavior of enterprises, and generate early warning information when the emission volume of enterprises reaches the early warning value, reminding enterprises that the emission volume corresponding to the current remaining emission rights is insufficient.

[0105] The transaction data in this embodiment may include, but is not limited to, transaction indicators, transaction volumes, and emission rights periods. Correspondingly, "determine the tax and fee information corresponding to the transferee based on the transaction data" in step 104 above may include: 1041. Determine the tax and fee information corresponding to the transferee according to the transaction indicators, the business scope of the transferee, and the income information generated by the increase in the emission rights due to the transaction volume of the transferee during the emission rights period; or 1041'. Send the transferee identifier, the transferor identifier, and the transaction data to the tax service platform, and the tax service platform determines the tax and fee information corresponding to the transferee based on the transaction data.

[0106] Furthermore, in the solution provided by this embodiment, the first server may further provide a contract generation function. That is, the method provided by this embodiment may further include the following steps: 109. Send contract upload notifications to the first client and the second client respectively; 110. If the contract information is initiated by the transferor, in response to the contract generation instruction triggered by the transferor through the first client, use the artificial intelligence tool deployed on the first server to determine the contract requirements of the transferor, and automatically generate contract information that meets the requirements of the transferor and is suitable for emission rights trading; 111. Send the contract information to the second client for the transferee to view, adjust, and confirm. The transferor and the transferee can conduct at least one round of contract negotiation through their respective corresponding clients for the contract information to obtain a target contract on which both parties reach an agreement. 112. After receiving the target contract confirmed and signed by the transferee and the target contract confirmed and signed by the transferor, trigger an indication that the transferor and the transferee have uploaded the transaction contract.

[0107] See Figure 5 The interface example shown. There is a control 7 of "Generate Contract" displayed on this interface, and this control 7 can also be called a contract generation control. When the user clicks this control 7, it can trigger the first server to retrieve the artificial intelligence tool deployed on the server side (such as an agent constructed and trained based on neural network algorithms) to automatically generate contract information suitable for the transferor and the transferee and suitable for the pollutant discharge right transaction. In a specific implementation, after the user clicks this control 7, a conversation page can be popped up or displayed on one side of the interface. The user can provide materials for the agent in the way of text input, voice input, or importing a draft. The agent can directly generate contract information based on the materials provided by the user. Of course, the user can also conduct multiple rounds of conversations with the agent to adjust and improve the contract information.

[0108] As Figure 6 shows a schematic flowchart of a pollutant discharge right trading method provided by another embodiment of the present application. The method provided in this embodiment is applicable to the second client corresponding to the transferee in the pollutant discharge right transaction. Specifically, the method includes: 201. After the transferee and the transferor reach a transaction intention, display the platform service fee information sent by the first server corresponding to the pollutant discharge right trading platform on the trading page corresponding to the pollutant discharge right trading platform. 202. Respond to the payment operation performed by the transferee on the trading interface and execute the platform service fee payment process. 203. After the transferee successfully pays the platform service fee and the transferor and the transferee complete the signing of the transaction contract through their respective clients, display the tax information sent by the first server on the trading page. The tax information is determined based on the transaction data of the transferee in the pollutant discharge right transaction. 204. Respond to the operation of the transferee on the trading interface for the tax information and jump to the tax payment page corresponding to the tax service platform so that the transferee can perform the tax payment operation according to the prompts on the tax payment page. 205. After the transferee completes the tax payment, display the trading page, and the trading page shows the tax payment information of the transferee feedback by the tax service platform. 206. Receive and display the successful information of the transfer of pollutant discharge rights corresponding to the transaction data fed back by the first server.

[0109] Further, the method provided in this embodiment may further include the following steps: 207. If the contract information is initiated by the assignee, a contract generation control is displayed on the transaction page; 208. In response to the operation of the assignee on the contract generation control, an artificial intelligence tool interaction page is displayed, so that the assignee can trigger the artificial intelligence tool to generate contract information that meets the needs of the assignee and is suitable for pollutant discharge rights trading by communicating with the artificial intelligence tool on the interaction interface; 209. In response to the confirmation instruction of the assignee on the contract information or the confirmation instruction after the assignee modifies and saves the contract information, the confirmed contract information is sent to the first client corresponding to the assignor, so that the assignor can review, adjust and confirm; 210. After at least one round of contract negotiation between the assignee and the assignor through their respective clients for the contract information, a target contract on which both parties reach an agreement is determined; 211. In response to the signing operation of the assignee on the target contract, the signed target contract by the assignee is sent to the first server, and the first server sends the target contract to the first client, so that the assignor can sign.

[0110] The specific form of the above "contract generation control" on the application interface may be Figure 5 the control 7 shown in; of course, it may also be other forms, and this embodiment does not make specific limitations on this.

[0111] Such as Figure 7 shows a schematic flowchart of a method for trading pollutant discharge rights provided in another embodiment of the present application. The method provided in this embodiment is applicable to the first client corresponding to the assignor in the trading of pollutant discharge rights. If the contract information is initiated by the assignor, the method provided in this embodiment may include: 301. After the assignor and the assignee reach a trading intention and it is determined that the assignee has successfully paid the platform service fee, a contract generation control is displayed on the transaction page corresponding to the pollutant discharge rights trading platform; 302. In response to the operation of the assignor on the contract generation control, an artificial intelligence tool interaction page is displayed, so that the assignor can trigger the artificial intelligence tool to generate contract information that meets the needs of the assignor and is suitable for pollutant discharge rights trading by communicating with the artificial intelligence tool on the interaction interface; 303. In response to the confirmation instruction of the transferor for the contract information or the confirmation instruction after the transferor modifies and saves the contract information, send the confirmed contract information to the second client corresponding to the transferee, so that the transferee can review, adjust and confirm it; 304. After the transferee and the transferor conduct at least one round of contract negotiation on the contract information through their respective corresponding clients, determine the target contract on which both parties reach an agreement; 305. In response to the signing operation of the transferor on the target contract, send the target contract signed by the transferor to the first server, and the first server sends the target contract to the second client, so that the transferee can sign it.

[0112] The solution provided in the embodiment of the present application improves the intelligence of the pollutant discharge right trading platform. The pollutant discharge right trading platform not only serves as a trading platform for facilitating transactions, but also uses artificial intelligence tools to make the trading platform more intelligent, providing convenience for both trading parties.

[0113] In each embodiment of the present application, the design of the pollutant discharge right trading platform can be based on the Browser / Server information framework in the Internet environment, and adopt a three-tier architecture of a browser, a Web server, and a background database. The pollutant discharge right trading platform architecture, under the B / S three-tier architecture, includes a user presentation layer, a Web service layer, and a data service layer.

[0114] The user presentation layer is located on the client side, and its main task is to send service requests to the Web server and return results.

Government departments review the application information of pollutant discharge enterprises through this platform and summarize and statistically analyze pollution source information, etc. The trading center organizes transactions through this platform. The public supervises the trading information and trading process.

[0115] The Web server layer is located on the Web server side, and its main task is to receive user requests, execute corresponding operations, send data processing requests to the database server, and send the obtained results to the client.

[0116] The data service layer is located at the data server end. It can share a computer with the Web server, or it can be a separate data server connected to the Web server through the network. The main task of the data service layer is to accept the Web server's request for database operations, implement functions such as query, modification, and update of the database, and submit the results of the operation to the Web server. The databases included in the data service layer include the basic information database of pollutant discharge enterprises, the purchase index database, the transaction information database, the pollutant discharge permit database, the quota tracking and detection data, the index configuration database, the user authority database, etc.

[0117] In this application, the emission rights trading platform is also connected with other platforms, such as the tax service platform, the fiscal open platform, etc. For example, data interaction is achieved by calling the API provided by the emission rights trading platform. For cloud platform docking, a private network connection can be established through VPN and dedicated lines (such as AWS Direct Connect) to achieve data interaction between platforms.
