Description

Technical Field

[0001] This application relates to the field of digital supply chain management technology for plastics and chemicals trade, and in particular to a method and system for full-chain compliance management of plastics and chemicals trade based on the integration of four flows. Background Technology

[0002] The current plastics and chemical trading industry is in a stage of competition for existing market share. The supply chain is long and the links are independent of each other. Traditional operating models generally suffer from a deep disconnect between the flow of commerce, logistics, capital, and information. Data from various business systems is isolated, forming information silos and making it impossible to achieve full-chain data synchronization and linkage.

[0003] In terms of compliance management, existing plastic and chemical trading companies rely on manual processing of documents and offline verification of compliance materials. The application of tax incentive policies requires manual verification of contracts, invoices, and logistics documents one by one, which is prone to problems such as missing documents, incorrect associations, and data tampering. There is no mandatory compliance verification mechanism for business flow, and illegal transactions cannot be stopped in advance, resulting in high compliance risks.

[0004] Transaction data tracing relies on manual review of paper files or scattered electronic data, resulting in extremely low tracing efficiency; tax declaration requires the manual collection of massive amounts of compliance data, which is time-consuming, has a high error rate, and cannot meet regulatory and policy reporting requirements. Summary of the Invention

[0005] This application provides a method and system for full-chain compliance management of plastic and chemical trade based on the integration of the four flows (information, capital, logistics, and funds). It aims to solve the problems of existing technologies that only have a single supply chain management system, document storage system or tax declaration tool, which have not achieved deep integration of the four flows, have not embedded tax incentive compliance requirements into the entire business process, have not set up a mandatory compliance inspection mechanism for business nodes, have not formed an immutable full-chain compliance evidence chain, and have no integrated solution for automatically generating compliance declaration reports.

[0010] In some embodiments, enabling the platform's intelligent document center to automatically associate service contracts, logistics documents, invoices, and bank statements to generate an immutable and compliant evidence chain includes: using the unique identifier of the transaction order as the association dimension, matching the corresponding transaction's service contract, warehousing documents, outbound documents, transportation receipt documents, VAT invoices, and bank transfer statements; adding a timestamp and unique identifier to each associated document; and storing the document data using encrypted storage to ensure that the document data cannot be tampered with.

[0011] In some embodiments, the setting of mandatory compliance checkpoints at key nodes of the business process to verify the completeness of compliance documents and block the business process if there are no valid compliance documents includes: setting compliance checkpoints at the order confirmation node, goods outbound node and payment settlement node respectively, verifying the completeness, validity and relevance of the compliance documents required for the corresponding node one by one, locking the current business node if the document verification fails, prohibiting the business from entering the next processing stage, and triggering a compliance anomaly warning.

[0012] In some embodiments, the step of achieving full-process data traceability of transactions based on the corresponding compliance evidence chain includes: using the unique identifier of the transaction order as the retrieval basis, associating the full-process compliance evidence chain of the corresponding transaction with the business operation log, retrieving the document data, flow node information and operation records of the entire transaction process, and forming a complete and verifiable transaction traceability link.

[0013] In some embodiments, the automatic collection of compliance data according to the tax declaration cycle to generate a compliance declaration report for tax incentives in the plastics and chemicals trade includes: according to the set tax declaration cycle, screening plastics and chemicals trade transaction data that meet the conditions for tax incentives, automatically collecting the compliance evidence chain information of the corresponding transactions, filling in the data according to the tax incentive declaration document format, and generating a tax incentive compliance declaration report that can be directly submitted.

[0014] In some embodiments, the method further includes: constructing a compliance risk assessment model for plastic and chemical trade based on machine learning algorithms; collecting transaction document data, business flow data, and transaction entity qualification data as input data for the compliance risk assessment model for plastic and chemical trade; calculating the transaction compliance risk score through the compliance risk assessment model for plastic and chemical trade; and automatically triggering secondary compliance verification and risk warning for high-risk transactions with risk scores exceeding a preset threshold, thereby improving the accuracy of compliance control.

[0015] Secondly, this application provides a compliance management system for the entire plastics and chemical trade chain based on the integration of four flows (information, capital, logistics, and capital), the system comprising: The platform building unit is used to build a unified business operation platform for plastics and chemicals trade, embedding relevant tax incentive compliance requirements into the platform's business processes and configuring corresponding compliance rule engines; through the platform, the flow of commerce, logistics, capital and information in plastics and chemicals trade is integrated to achieve a closed loop of commerce flow throughout the entire procurement and sales process, fully visualized logistics control of warehousing and transportation, integrated business and financial settlement of capital flow, and synchronized data and information flow linkage across the entire chain; The central activation unit is used to activate the platform's intelligent document center, automatically linking service contracts, logistics documents, invoices, and bank statements to generate an unalterable chain of compliant evidence; it sets up mandatory compliance checkpoints at key nodes in the business process to verify the completeness of compliant documents, and blocks the business process if there are no valid compliant documents. The report generation unit is used to achieve full-process data traceability of transactions based on the corresponding compliance evidence chain; automatically collect compliance data according to the tax declaration cycle and generate compliance declaration reports for plastic and chemical trade tax incentives; it also uses big data analysis technology to conduct multi-dimensional analysis of compliance data, obtain compliance analysis results, and dynamically iterate compliance rules based on the compliance data analysis results, including adding compliance verification rules for frequently occurring compliance anomalies; adjusting existing compliance rule parameters in response to policy updates to achieve self-optimization of compliance rules; adapting to business process adjustments by combining compliance rule iteration results, and ensuring the comprehensiveness of document storage by adapting to new document types and formats; and regularly generating compliance control effectiveness evaluation reports, including indicators such as compliance verification pass rate, business interruption rate, risk warning accuracy rate, and policy adaptation efficiency, to further optimize compliance control strategies based on compliance control effectiveness evaluation reports, achieving continuous iterative upgrades of compliance control.

[0016] This application breaks down data silos across various stages of the plastics and chemicals trade, achieving deep integration and real-time linkage of business flow, logistics, capital flow, and information flow, significantly improving the operational efficiency of the entire chain. By embedding tax incentive compliance requirements into business processes, compliance rules can be flexibly configured to quickly adapt to policy changes, reducing the difficulty of policy adaptation and compliance costs. The intelligent document center automatically associates various documents to generate an immutable evidence chain, eliminating issues such as missing documents, tampering, and incorrect associations, ensuring the authenticity of compliance evidence. Mandatory compliance checkpoints are set up at key business nodes, and ineffective compliance documents directly block business flow, avoiding compliance risks from the source. Relying on the compliance evidence chain, the entire transaction process is traceable, and data from all stages can be quickly retrieved, improving the efficiency of regulatory verification. Compliance data is automatically collected according to the declaration cycle and declaration reports are generated, replacing manual operations and improving the accuracy and efficiency of declarations.

[0026] The current plastics and chemical trading industry is in a stage of competition for existing market share. The supply chain is long and the links are independent of each other. Traditional operating models generally suffer from a deep disconnect between the flow of commerce, logistics, capital, and information. Data from various business systems is isolated, forming information silos and making it impossible to achieve full-chain data synchronization and linkage.

[0027] In terms of compliance management, existing plastic and chemical trading companies rely on manual processing of documents and offline verification of compliance materials. The application of tax incentive policies requires manual verification of contracts, invoices, and logistics documents one by one, which is prone to problems such as missing documents, incorrect associations, and data tampering. There is no mandatory compliance verification mechanism for business flow, and illegal transactions cannot be stopped in advance, resulting in high compliance risks.

[0028] Transaction data tracing relies on manual review of paper files or scattered electronic data, resulting in extremely low tracing efficiency; tax declaration requires the manual collection of massive amounts of compliance data, which is time-consuming, has a high error rate, and cannot meet regulatory and policy reporting requirements.

[0029] Existing technologies only exist as single supply chain management systems, document storage systems, or tax filing tools, failing to achieve deep integration of the four flows (information, capital, logistics, and capital), failing to embed tax incentive compliance requirements into the entire business process, failing to set up mandatory compliance inspection mechanisms for business nodes, failing to form an immutable chain of compliance evidence across the entire supply chain, and lacking an integrated solution for automatically generating compliance filing reports.

[0030] To solve the above problem, please refer to Figure 1 This application provides a method for full-chain compliance management of plastics and chemicals trade based on the integration of four flows (information, capital, logistics, and information), applied to computer equipment. The computer equipment can be deployed on a single server or server cluster. It can also be deployed on handheld terminals, laptops, wearable devices, or robots, etc. It should be noted that every piece of information involved in the method provided in this application is extracted with the authorization of the relevant user and in accordance with relevant regulations, and will not infringe on user privacy.

[0031] The provided method for full-chain compliance management of plastics and chemicals trade based on the integration of four flows includes steps S101 to S103. Details are as follows: Step S101. Build a unified business operation platform for plastics and chemicals trade, embed relevant tax incentive compliance requirements into the platform's business processes, and configure the corresponding compliance rule engine; through the platform, integrate the flow of commerce, logistics, capital and information in plastics and chemicals trade to achieve a closed loop of commerce flow throughout the entire procurement and sales process, visualized logistics control throughout the warehousing and transportation process, integrated business and finance capital flow settlement, and synchronized data flow and information flow linkage across the entire chain.

[0032] Specifically, the core technology of this step is to build an integrated business platform that embeds tax incentive compliance requirements into business processes. Simultaneously, it achieves full-chain integration of the plastics and chemicals trade's commercial flow, logistics, capital flow, and information flow. The platform is built using a modular and scalable architecture to create a unified business operation platform for plastics and chemicals trade. The platform includes built-in business adaptation modules, data interaction modules, and process control modules. After deployment, the platform connects with the company's existing procurement management, sales management, warehousing management, transportation management, and financial accounting systems to establish a unified master data management standard, unify the basic data formats and coding rules for products, customers, and suppliers, and eliminate data barriers between systems.

[0033] The implementation of compliance requirements is achieved by transforming tax incentive compliance policy standards into digital verification rules and embedding them into the platform's business workflow; a compliance rule engine is configured, which supports parameterized editing and adjustment, allowing users to adapt to policy changes by adjusting rule parameters without modifying the platform's core program; and compliance verification rules are bound to all business nodes, including purchase ordering, order review, goods delivery, and payment settlement, to achieve deep integration of compliance requirements with business processes.

[0034] The implementation of the four-in-one integration includes: Implementation of closed-loop business flow: The platform enables online processing of the entire process from procurement sourcing, supplier quotation, purchase order generation, sales lead follow-up, sales contract signing, and order fulfillment, achieving closed-loop management of business flow from procurement to sales; Logistics visualization implementation: The platform connects with warehousing equipment and transportation positioning terminals to collect real-time data on the status of goods entering and leaving the warehouse, storage within the warehouse, and transportation in transit, thereby achieving visualized management and control of the entire warehousing and transportation process. Implementation of fund flow settlement: Based on business documents, financial accounting is automatically triggered to automatically generate accounts receivable and accounts payable, connect with online payment channels to realize automatic fund settlement, and achieve integrated business and financial management; Information flow linkage implementation: Build a platform data transfer module to synchronize data across all stages of commerce, logistics, and capital flow in real time, ensuring that data in each business stage is updated synchronously and interconnected.

[0035] Step S102. Activate the platform's intelligent document center to automatically associate service contracts, logistics documents, invoices, and bank statements to generate an unalterable chain of compliant evidence; set up mandatory compliance checkpoints at key nodes in the business process to verify the completeness of compliant documents, and block the business process if there are no valid compliant documents.

[0036] Specifically, the core technology of this step is to generate a compliance evidence chain through the intelligent document center and perform mandatory compliance verification at key business nodes. The intelligent document center is implemented by activating the platform's built-in intelligent document center, using the order number of each plastics and chemicals trade transaction as a unique identifier, automatically matching and capturing the service contract, warehousing and logistics documents, sales and purchase invoices, and bank transfer data corresponding to the transaction; adding a generation time identifier and an independent storage code to each captured document, and using encrypted storage to save the document data to ensure that the document data cannot be tampered with, thus forming a complete compliance evidence chain.

[0037] Mandatory compliance checkpoints are implemented by setting up mandatory compliance checkpoints at three key business flow nodes: order confirmation, goods shipment, and payment settlement. Each checkpoint automatically retrieves the corresponding transaction's compliance evidence chain and verifies the completeness and validity of the service contract, logistics documents, invoices, and bank statements. If any valid compliance documents are found to be missing, the platform immediately locks the current business node, prohibiting the business from proceeding to the next stage, and triggers a compliance anomaly warning. The business is only allowed to continue after the documents are supplemented and verified.

[0038] Step S103. Achieve full-process data traceability for transactions based on the corresponding compliance evidence chain; automatically collect compliance data according to the tax declaration cycle and generate a compliance declaration report for plastic and chemical trade tax incentives; furthermore, use big data analysis technology to conduct multi-dimensional analysis of compliance data, obtain compliance analysis results, and dynamically iterate compliance rules based on the compliance data analysis results, including adding compliance verification rules for frequently occurring compliance anomalies; adjusting existing compliance rule parameters in response to policy updates to achieve self-optimization of compliance rules; adapting to business process adjustments by combining compliance rule iteration results, and ensuring the comprehensiveness of document storage by adapting to new document types and formats; and regularly generating compliance control effectiveness evaluation reports, including indicators such as compliance verification pass rate, business interruption rate, risk warning accuracy rate, and policy adaptation efficiency, and further optimizing compliance control strategies based on the compliance control effectiveness evaluation reports to achieve continuous iterative upgrades of compliance control.

[0039] Specifically, the core technology of this step is to complete transaction traceability based on the compliance evidence chain, automatically complete the collection of compliance data and report generation on a periodic basis, and implement full-process transaction traceability by using the transaction order number as the retrieval basis. The platform calls the corresponding transaction's compliance evidence chain, business flow records, and operation log data, and integrates and displays them in the order of business occurrence time. This enables the data of the entire transaction process from order placement to settlement to be queryable and traceable, ensuring that the entire transaction process is verifiable.

[0040] The compliance declaration report generation process involves setting up tax declaration cycle parameters within the platform. The platform automatically filters plastic and chemical trade transaction data that meet the tax incentive conditions according to the set cycle, collects the corresponding transaction compliance evidence chain and business accounting data, and automatically fills in the collected compliance data according to the document format requirements for tax incentive declaration, generating a standardized plastic and chemical trade tax incentive compliance declaration report. The report can be directly used for tax declaration submission.

[0041] In some embodiments, the establishment of a unified business operation platform for plastics and chemicals trading includes: building the platform's basic framework using a microservice architecture, configuring a unified business workbench, connecting to the procurement management system, sales management system, warehouse management system, transportation management system, and financial accounting system, establishing a master data management system, unifying the standards and codes for product data, customer data, and supplier data, and achieving real-time data exchange between the various systems.

[0042] This embodiment addresses the technical aspects of building a unified business operation platform for the plastics and chemicals trade. It employs a microservice architecture to decompose platform functional modules, establishing the platform's basic framework and deploying service registration, configuration management, and service gateways. A unified business workbench is configured, integrating functions such as task processing, message reminders, data querying, and quick access to business information. Standardized interfaces are used to connect with the enterprise's existing procurement management system, sales management system, warehouse management system, transportation management system, and financial accounting system, establishing data transmission channels between systems. A master data management system is established, unifying the input standards and data formats for product codes, product specifications, customer information, and supplier information. Master data cleaning, deduplication, and calibration are performed to achieve real-time data interoperability and consistency across systems.

[0043] In some embodiments, embedding the relevant tax incentive compliance requirements into the platform's business processes and configuring the corresponding compliance rule engine includes: presetting document templates required for tax incentive compliance, defining mandatory verification fields for documents, binding tax incentive compliance verification rules to each node of the business process, supporting parameterized adjustment of compliance rules, and adapting to policy changes by adjusting parameters without modifying the platform's core code.

[0044] This embodiment addresses the technical aspects of embedding tax incentive compliance requirements into business processes and configuring a compliance rule engine. It pre-defines electronic templates for service contracts, orders, invoices, and logistics documents required for tax incentive compliance within the platform, clearly defining the mandatory verification fields for each template. Tax incentive compliance verification rules are linked to all business nodes, including purchase order placement, order review, goods shipment, payment settlement, and financial accounting. Verification rules are automatically invoked when a node is triggered. The compliance rule engine employs a parameterized configuration mode, converting policy requirements into editable parameters. When policies change, only parameter values ​​and verification logic need to be adjusted; rule updates and adaptations can be completed without modifying the platform's core code.

[0045] In some embodiments, the integration of the plastics and chemicals trade's commercial flow, logistics, capital flow, and information flow through the platform to achieve a closed-loop commercial flow throughout the entire procurement and sales process, visualized logistics control throughout warehousing and transportation, integrated business and financial capital flow settlement, and synchronized data flow across the entire chain includes: completing the entire process from procurement sourcing to payment and from sales lead acquisition to payment collection online through the commercial flow end; connecting the logistics end to the warehousing operation system and transportation positioning equipment to synchronize the warehousing status and transportation location information of goods in real time; automatically generating accounts receivable and payable vouchers based on business documents through the capital flow end and connecting to the payment system to complete fund settlement; and building a data middle platform through the information flow end to synchronize data from each business link in real time, forming a unique and accurate source of business data.

[0046] This embodiment focuses on the technical aspects of platform integration of four flows (commerce, logistics, and capital) to achieve full-link linkage and control. On the commercial flow side, the platform facilitates the entire online process of procurement sourcing, price comparison, order generation, contract signing, and payment, as well as the entire online process of sales lead generation, pricing, order fulfillment, and payment collection, forming a closed-loop commercial flow. On the logistics side, interfaces connect to the warehousing operation system and transportation positioning equipment to collect real-time information on goods entering, shelving, picking, leaving, transferring, and their transit location and transportation trajectory, achieving full visualization of warehousing and transportation. On the capital flow side, accounts receivable and accounts payable vouchers are automatically generated based on business documents, and online payments are completed through bank payment systems, achieving integrated business and financial settlement. On the information flow side, a data platform is built to synchronize data from all aspects of the commercial, logistics, and capital flows in real time, establishing a unique source of business data to ensure real-time, unbiased data linkage.

[0047] In some embodiments, enabling the platform's intelligent document center to automatically associate service contracts, logistics documents, invoices, and bank statements to generate an immutable and compliant evidence chain includes: using the unique identifier of the transaction order as the association dimension, matching the corresponding transaction's service contract, warehousing documents, outbound documents, transportation receipt documents, VAT invoices, and bank transfer statements; adding a timestamp and unique identifier to each associated document; and storing the document data using encrypted storage to ensure that the document data cannot be tampered with.

[0048] This embodiment addresses the technical aspects of generating an immutable and compliant evidence chain through an intelligent document center. It uses the order number of each transaction as a unique identifier, and this identifier as the association dimension to automatically match the corresponding service contract, warehousing documents, outbound documents, transportation receipts, VAT invoices, and bank transfer records. A generation timestamp and independent storage identifier are added to each matched document. National cryptographic algorithms are used to encrypt and store the document data. Document data modification permissions and operation tracking mechanisms are set to ensure that the document data cannot be tampered with, forming a complete and authentic compliant evidence chain.

[0049] In some embodiments, the setting of mandatory compliance checkpoints at key nodes of the business process to verify the completeness of compliance documents and block the business process if there are no valid compliance documents includes: setting compliance checkpoints at the order confirmation node, goods outbound node and payment settlement node respectively, verifying the completeness, validity and relevance of the compliance documents required for the corresponding node one by one, locking the current business node if the document verification fails, prohibiting the business from entering the next processing stage, and triggering a compliance anomaly warning.

[0050] This embodiment addresses the technical aspects of setting mandatory compliance checkpoints at business nodes and blocking abnormal business flows. Compliance checkpoints are deployed at three core business nodes: order confirmation, goods dispatch, and payment settlement. The order confirmation node verifies the service contract and the completeness of order documents; the goods dispatch node verifies the validity of logistics documents; and the payment settlement node verifies the correlation between invoices and bank statements. After each checkpoint completes its verification, if any documents are missing, invalid, or incorrectly associated, the platform automatically locks the current business node, preventing the business from proceeding to the next processing stage. Simultaneously, a compliance anomaly warning is sent to the business manager and compliance administrator. The node is unlocked once the documents are complete and verified.

[0051] In some embodiments, the step of achieving full-process data traceability of transactions based on the corresponding compliance evidence chain includes: using the unique identifier of the transaction order as the retrieval basis, associating the full-process compliance evidence chain of the corresponding transaction with the business operation log, retrieving the document data, flow node information and operation records of the entire transaction process, and forming a complete and verifiable transaction traceability link.

[0052] This embodiment addresses the technical aspects of achieving full-process data traceability for transactions based on a compliance evidence chain. By using the unique identifier of the transaction order as the retrieval basis, the platform automatically associates the corresponding full-process compliance evidence chain and business operation logs for the transaction. In chronological order of the business occurrence, it retrieves document data, flow node information, operator records, and operation time information for the entire process of the transaction, from order placement, review, warehousing, transportation, and settlement. This integrates to form a complete and verifiable transaction traceability chain, supporting one-click retrieval and visual display, meeting the needs of regulatory verification and internal traceability.

[0053] In some embodiments, the automatic collection of compliance data according to the tax declaration cycle to generate a compliance declaration report for tax incentives in the plastics and chemicals trade includes: according to the set tax declaration cycle, screening plastics and chemicals trade transaction data that meet the conditions for tax incentives, automatically collecting the compliance evidence chain information of the corresponding transactions, filling in the data according to the tax incentive declaration document format, and generating a tax incentive compliance declaration report that can be directly submitted.

[0054] This embodiment addresses the technical aspects of periodically collecting compliance data and generating tax incentive compliance declaration reports. By pre-setting monthly and quarterly tax declaration cycle parameters within the platform, the platform automatically filters plastic and chemical trade transaction data that meet the tax incentive conditions according to the set cycle; automatically collects the corresponding transaction compliance evidence chain, business accounting data, and document information; and automatically fills in the collected compliance data according to the official document format for tax incentive declarations, generating a standardized tax incentive compliance declaration report that can be directly submitted and supports export in PDF and Excel formats.

[0055] In some embodiments, the method further includes: constructing a compliance risk assessment model for plastic and chemical trade based on machine learning algorithms; collecting transaction document data, business flow data, and transaction entity qualification data as input data for the compliance risk assessment model for plastic and chemical trade; calculating the transaction compliance risk score through the compliance risk assessment model for plastic and chemical trade; and automatically triggering secondary compliance verification and risk warning for high-risk transactions with risk scores exceeding a preset threshold, thereby improving the accuracy of compliance control.

[0056] This embodiment focuses on the technical content of intelligent compliance risk assessment and early warning based on machine learning. It constructs a compliance risk assessment model for plastics and chemicals trade based on machine learning classification algorithms, and collects historical compliant transaction data and abnormal transaction data to complete model training and verification. It collects transaction document data, business flow data, and transaction entity qualification data in real time as model input data. The model outputs a transaction compliance risk score through feature extraction and calculation. It presets a risk score threshold. For high-risk transactions that exceed the threshold, the platform automatically triggers a secondary full-process compliance verification and pushes a graded risk warning to the compliance management department to improve the accuracy and foresight of compliance control.

[0057] In some embodiments, such as Figure 2As shown, this paper provides a detailed explanation of the overall application scenario of the full-chain compliance management method for the plastics and chemicals trade. By building a unified business operation platform for plastics and chemicals trade and embedding compliance, tax incentive compliance requirements are embedded into the core nodes of the platform's business processes. At the same time, a compliance rule engine is configured to achieve deep binding between compliance requirements and business processes. The platform serves as the core carrier of the flow of commerce, logistics, capital, and information, and connects to each business flow management module to achieve four core functions: closed-loop procurement and sales process, full-process visualized management and control of warehousing and transportation, integrated business and financial settlement, and full-chain data synchronization and linkage. This provides basic architectural support for full-chain compliance management.

[0058] The intelligent document storage system utilizes a built-in intelligent document center on the platform. Based on the entire transaction data, it automatically associates four core documents: service contracts, logistics documents, invoices, and bank statements. Through document matching, encrypted storage, and identifier binding processes, it generates an immutable and compliant evidence chain, providing core data support for subsequent compliance verification, traceability, and declaration.

[0059] The compliance control node implementation involves setting up mandatory compliance checkpoints at key nodes in the business process. These checkpoints automatically retrieve the compliance evidence chain generated by the intelligent document center to verify the validity, completeness, and relevance of the documents. If the verification result is that there are no valid compliant documents, the platform immediately executes a business process blocking operation to prevent non-compliant transactions from occurring at the source.

[0060] The traceability and reporting system relies on an immutable chain of compliance evidence to enable full-process data traceability for transactions, allowing regulatory authorities and enterprises to verify information at any time. At the same time, the platform automatically collects compliance data according to the tax declaration cycle, and combines the chain of compliance evidence with business data to generate a compliance declaration report for plastic and chemical trade tax incentives with one click, replacing manual declaration work and improving the efficiency and accuracy of compliance declaration.

[0061] In some embodiments, supplementary designs are made for compliance management of plastic and chemical trade in multi-entity collaborative scenarios. By enabling multi-entity platform access, plastic and chemical trade participants (suppliers, distributors, warehouse operators, transporters, and tax regulators) to access the unified business operation platform for plastic and chemical trade through a unified identity authentication system, differentiated operation permissions and data viewing permissions are assigned to each entity to ensure that the data interaction between the entities is secure and compliant.

[0062] The collaborative business flow links suppliers to submit supply information through the platform, distributors to submit procurement needs, warehouse operators to synchronize the storage status of goods, and transportation operators to upload transportation tracks. Data from all parties is synchronized to the platform in real time. Based on a compliance rule engine, the platform performs real-time compliance verification on the business data of multi-party interactions, such as verifying whether the supplier's qualifications meet the tax incentive requirements and whether the warehouse operator's qualifications have compliant storage qualifications.

[0063] Cross-entity document storage, through the intelligent document center, not only links internal enterprise documents, but also automatically synchronizes and accesses the entity's compliant documents (such as supplier qualification certificates, warehouse registration documents, and transportation compliance certificates), generating a complete compliant evidence chain containing multiple party documents for each cross-entity transaction. The evidence chain is synchronized to the platforms of each entity and regulator, realizing multi-party sharing and traceability.

[0064] The collaborative compliance early warning system addresses situations such as document mismatches, expired entity qualifications, and abnormal business processes that occur in multi-entity collaborative transactions. The platform uses a compliance rule engine to identify these issues in real time and sends collaborative compliance early warnings to the relevant entities and regulators, guiding each entity to make timely rectifications and ensuring the compliance of multi-entity collaborative transactions.

[0065] In some embodiments, supplementary designs are made for compliance management scenarios in cross-border plastics and chemicals trade. By adapting cross-border compliance rules, the compliance rule engine is built with exclusive compliance rules for cross-border plastics and chemicals trade, including import and export tariff policies, foreign exchange management requirements, cross-border logistics and customs declaration specifications, and cross-border tax incentive details, to achieve differentiated configuration of cross-border business compliance rules and domestic business rules, and adapt to the complex compliance requirements of cross-border trade.

[0066] The integrated cross-border document storage system adds a cross-border document adaptation module to the intelligent document center. This module automatically links documents required for cross-border trade, such as customs declarations, commodity inspection certificates, foreign exchange payment vouchers, and import / export licenses. Combined with domestic trade documents (service contracts, logistics documents, invoices, and bank statements), it generates an immutable and compliant evidence chain covering the entire cross-border process, meeting the requirements of cross-border regulatory verification.

[0067] Cross-border business node control involves setting up mandatory compliance checkpoints at core nodes of cross-border trade (customs declaration node, cross-border logistics node, foreign exchange settlement node, and cross-border tax declaration node) to verify the relevance and compliance of cross-border documents with domestic documents. If the document verification fails, the flow of the corresponding cross-border business node is blocked, and an early warning is sent to the cross-border compliance management department.

[0068] Cross-border traceability and declaration rely on the cross-border compliance evidence chain to achieve full-process data traceability in cross-border trade transactions, supporting verification by cross-border regulatory departments such as customs and taxation. At the same time, the platform automatically collects cross-border trade compliance data according to the cross-border tax declaration cycle, generates a cross-border plastics trade tax incentive compliance declaration report, and adapts to the cross-border trade declaration process.

[0069] In some embodiments, supplementary designs are made for compliance and batch control scenarios of bulk transactions in the plastics and chemicals trade. Through bulk transaction data import, users can import plastics and chemicals trade transaction data (including commercial flow data, logistics data, and capital flow data of multiple transactions) through the platform. The platform automatically parses the bulk transaction data and establishes the association between each transaction and the documents.

[0070] Batch compliance intelligent verification uses a compliance rules engine to perform batch compliance verification on imported transaction data. This includes verifying the completeness and validity of documents for each transaction, as well as the consistency of compliance logic between batch transactions (such as incorrect document association in multiple transactions, conflicting tax incentive application conditions in batch transactions, etc.). Abnormal transactions found during batch verification are automatically marked and categorized for display.

[0071] Batch business blocking targets non-compliant transactions identified in batch verification. The platform executes batch business blocking operations to lock the corresponding business nodes of the batch transactions. At the same time, it automatically generates a batch compliance anomaly report, which clarifies the details of the abnormal transactions, the reasons for the anomalies, and rectification suggestions to guide compliance management personnel in batch processing.

[0072] Batch traceability and batch declaration are achieved through the platform by using batch transaction sets as units and based on the compliance evidence chain to achieve batch transaction traceability. It supports one-click viewing of the entire compliance information of batch transactions. According to the tax declaration cycle, it automatically collects batch transaction compliance data and generates a batch plastic and chemical trade tax incentive compliance declaration report, thereby improving the efficiency of batch transaction compliance declaration.

[0073] In some embodiments, supplementary designs are made for the dynamic adaptation and iterative optimization scenarios of compliance management in the plastics and chemicals trade. The platform builds a compliance data collection module to collect business flow data, compliance verification data, risk warning data, and regulatory feedback data in real time, and constructs a dynamic database for compliance management. Through big data analysis technology, compliance data is analyzed in multiple dimensions to identify weak links in compliance management.

[0074] The compliance rules are dynamically iterated based on the results of compliance data analysis. The compliance rule engine supports dynamic iteration and optimization of compliance rules. For example, it automatically adds compliance verification rules for frequently occurring compliance anomaly types and automatically adjusts the parameters of existing compliance rules in response to policy updates, thereby achieving self-optimization of compliance rules.

[0075] The platform's dynamic function adaptation combines the results of compliance rule iterations to automatically adapt to business process adjustments, achieving dynamic matching between business processes and compliance requirements without manual intervention. At the same time, the intelligent document center automatically adapts to newly added document types and formats, ensuring the comprehensiveness of document storage.

[0076] The platform regularly generates compliance management effectiveness evaluation reports, including indicators such as compliance verification pass rate, business interruption rate, risk warning accuracy rate, and policy adaptation efficiency. Based on the evaluation results, compliance management strategies are further optimized to achieve continuous iteration and upgrading of compliance management.
