[0050] 2. In this agricultural digital land transfer credit management system, by setting up an administrator module in the background management unit, the administrator module's permissions and functions can be used to monitor and trace the contract signing templates and clause contents of merchants in real time, avoiding the emergence of seriously unreasonable clauses and ensuring that both parties sign voluntarily and peacefully. Therefore, the contract signing process of land transfer can be effectively supervised, preventing illegal operations and fraud.

[0051] 3. In this agricultural digital land transfer credit management system, by establishing a unified agricultural digital land transfer credit management system as a neutral party to conduct contract signing, the land transfer contract and payment information are automatically generated throughout the process without manual operation, enabling unified digital management. This ensures that land transfer information does not become isolated, and thus guarantees the effective integration and sharing of transfer information, facilitating practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 It is the internal module schematic diagram of the agricultural digital land transfer credit management system of the present invention;

[0053] Figure 2 It is the schematic diagram of the verification process of the contract verification module in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] In a specific embodiment, as Figure 1As shown in the figure, an agricultural digital land transfer credit management system is integrated on the PC side. When merchants use it, they can create contracts through the contract creation module inside the contract management module 2: First, select a template to initiate a contract; then add signatories and plot descriptions: For the leased property, fill in the leased property information (village group, plot name, plot code, location boundaries, area, quality grade, land type, contract code for land contracting, remarks) by oneself; automatically calculate the total area of the filled plots; then add attachments: 1. Attachment 1: Photos of the certificates of both parties (for individuals: front and back of the ID card; for enterprises: front and back of the legal person's ID card, business license photo); 2. Attachment 2: Certificate of land ownership for the leased land; 3. Attachment 3: Attached drawing of the boundaries of the leased land; 4. Attachment 4: Others.

[0056] After the contract is initiated, it will automatically reach the other party's account. The other party's account can preview the entire contract PDF file through the contract preview module; at the same time, through the contract details viewing module, it can display the basic information of the contract, signatories, signing status, operation time, and information of the pushed signing SMS for the signatories to view;

[0057] Of course, the other party can also directly confirm the signing through the contract signing module. When confirming the signing, insert the official seal. The official seal has been entered when registering the account system, and at the same time, the official seal inserted in the contract can also be cleared; and the contract can also be rejected through the contract rejection module. Whether it is to confirm the signing or reject the signing, it needs to be confirmed through Ukey / SMS.

[0058] After the contract is signed and confirmed, it will enter the payment status. Through the payment list viewing module inside the contract payment module, the contracts to be paid can be viewed, and through the payment screening module, the contracts after payment can be screened according to the contract signing time or contract name.

[0059] By establishing a unified agricultural digital land transfer credit management system as a neutral party for contract signing, the land transfer contract and payment information are automatically generated throughout the process without manual operation, enabling unified digital management, so that the land transfer information will not appear as isolated islands, and further ensuring that the transfer information can be effectively integrated and shared, facilitating actual applications.

[0060] System administrators can manage the templates, contracts, and SMS logs inside the system through the administrator module inside the background management unit, and at the same time can conduct online verification of the signed contracts to verify whether the contract content and signatures have been tampered with, further ensuring the authenticity of contract signing.

[0061] During the specific operation process, the template management module can be used to manage templates one by one. For the templates within the system, selection and download are supported, and multiple selections for batch download are allowed. The download format is a pdf file, and the naming rule for the download file name is: Name of Signatory A + Name of Signatory B + Contract Name + Download Time + Serial Number (Example: Land Transfer Contract between Chen Yong and Hefei Yicun Information Technology Co., Ltd.;

[0062] The contract management module can also be used to manage all contracts within the system in all states. The contract states include contracts to be signed, completed, rejected, expired, revoked, due (contract expiration), and terminated. At the same time, the contract list fields are displayed, including contract name, initiator, all signatories, signing status, contract type, initiation time, and expiration time. Through the contract management module, contracts within the system can also be filtered by contract type (including self-owned template contracts and platform template contracts), initiator, keyword, signatory, and initiation time;

[0063] At the same time, the contract management module can also be used to download the credit information within the system, including the user credit PDF files of both signatories and the land credit PDF file of one party. First, it is packaged by contract, and then the compressed packages are packaged and downloaded together. The naming rule for the download file name is: 1. User credit: Signatory Name + User Credit Report + Download Time + Serial Number; 2. Land parcel credit: Signatory Name (land operator) + Land Parcel Credit Report + Download Time + Serial Number. This is convenient for system administrators to view and evaluate the credit of both parties to the contract.

[0064] The user rankings are jointly output through the credit information management module, contract revocation module, and contract rejection module, and then the optimal user rankings are screened and matched with users through the payment screening module and monitoring module. The specific steps are as follows:

[0065] Step 1: Set decision variables. Through the lease time value T and lease area value S in the contract signing module, and determine the influence value Z of the tenant through the credit information management module to construct a variable group F(T, S, Z);

[0066] Step 2: Estimate the optimal lease duration Y through the decision variables, calculate the optimal lease time of the lessee through the objective function, obtain the lease time of regular lessees, set a threshold through the regular lease time, and judge whether Y is greater than the threshold. If it is greater than the threshold, assign the lessee to the longest lease time and preferentially allocate the lease area size; otherwise, lease according to the shortest time:

[0067]

[0068] In the above formula, N is the sum of the contract rejection and contract revocation times.

[0069] And through the contract verification module, it is possible to conduct online verification on the contracts uploaded for use (i.e., the contracts after signing and payment). Verification logic: Upload a contract file, verify the integrity of its file content and whether it has been modified twice; verify whether the signature corresponds to the signature serial number in the database. The verification process is as Figure 2 shown.

[0070] In addition, through the SMS log management module, it is possible to record the SMS sent by the platform and simultaneously record the time node content when the SMS is triggered, so as to facilitate the management personnel to query and manage the contract signing information.

[0071] By setting up the administrator module, it is possible to use the permissions and functions of the administrator module to monitor and trace the contract signing templates and clause contents of merchants in real time, avoid the occurrence of seriously unreasonable clauses, ensure the voluntary and peaceful signing of both parties, and thus effectively supervise the contract signing process of land transfer, avoiding illegal operations and fraud.

[0072] At the same time, merchants can view and operate on all contracts through the contract status management module, including contracts that are to be signed, to be improved, completed, rejected, expired, revoked, and due (contract expiration); at the same time, use the contract list field management module to display the list fields of the contract, including contract name, initiator, all signatories, signing status, contract type, initiation time, expiration time, and related operations (view details, revoke, sign, reject); and can perform contract list screening operations on contract type, issuing role, signing time, contract name, template name, and signatory through the contract screening module; merchants can also trigger the SMS log through the contract revocation module, send a confirmation SMS, and input the verification code of the SMS confirmation to achieve the contract revocation operation; at the same time, merchants can batch download contracts through the contract download module. By selecting the contracts and downloading the contract PDF files to the local, the naming rule for the downloaded file name is: Name of Signatory A + Name of Signatory B + Contract Name + Download Time + Serial Number.

[0073] In addition, before signing the contract, merchants or signatories can also view the credit information of the plot or user through the contract review module, and can batch download the credit files. The naming rule for the downloaded file name is: 1. User credit: Name of Signatory + User Credit Report + Download Time + Serial Number; 2. Plot credit: Name of Signatory (land operator) + Plot Credit Report + Download Time + Serial Number.

[0074] By downloading and viewing the credit information of the other party, it is possible to effectively obtain the credit information and historical signing records of the other party, thereby avoiding the trust risks existing in the transfer process and ensuring the symmetry of agricultural land transfer management information.

[0075] In addition, merchants can also select and manage the templates within the system through the Template Management Module II, and find suitable templates for their own use. The templates include platform templates and quick templates. For platform templates, they can be directly retrieved and used, while for quick templates, they need to be newly created. When creating a quick template, the following information needs to be entered: template name (displaying 30 characters, with the excess automatically wrapped to the next line); template description (displaying 30 characters, with the excess automatically wrapped to the next line); creator (the account to which the template belongs); creation time (the time when the template was successfully created); and template ID (18 - digit lowercase letters + numerical code). After the quick template is newly created and saved, it can be modified through editing: 1. Click the edit button to enter the basic information editing page, where the template name and template description can be modified; 2. Click "Next" to enter the page for improving contract information. This page defaults to loading the content data before modification, and the filled - in data can be directly modified; 3. Click "Next" to enter the preview and save page. Click the save template button, and a save confirmation box will pop up. Confirm to save. Saving after editing will replace the content data before modification and the modified items such as the name.
