Description

Method for importing deposit and remittance under collection item based on block chain and storage medium

Technical Field

The invention relates to the technical field of import collection and deposit in import and export trade, in particular to a method for carrying out import deposit and deposit under a collection item based on a block chain and a computer-readable storage medium.

Background

The import deposit is the business that the bank applies for by the importer, provides short-term fund financing when the bank pays the external money and is paid by the applicant according to the agreed interest rate and term. According to the settlement mode, the method is divided into import deposit and remit under the letter of credit, import deposit and remittance. The import deposit under the collection item is also called import collection deposit, which is a financing payment for providing the importer by the collection agency with the import collection documents including the property right documents as the mortgage. The basic method is that after the exporter delivers the goods, the consignment application is filled in and delivered to the consignment bank by virtue of the complete set of documents (including the commercial documents such as the transportation documents, the drafts and the invoices) which are in accordance with the contract requirements, and the consignment bank sends the consignment book together with the drafts and the documents to the consignment bank, and then the consignment bank delivers the consignment book to the importer. The importer pays the bill or accepts the bill depending on the nature of the commitment. The collection agency can open a receipt for collecting the trusts according to the application of the deposit exchange of the importer, firstly fills money in the receipts, and returns the collected money to the bank after the importer carries out goods processing, selling or resale.

However, the existing import collection and pledge method has the following problems:

1. because the collection and the deposit are entrusted as the security document and the document is the paper document, the fraud of the document also happens occasionally in international trade, and the financing risk of banks is increased.

2. In the traditional international trade financing activity, the bank and the imported enterprise have asymmetric information, the bank does not know whether the financial condition of the imported enterprise is stable or not and whether the historical credit condition is good or not, so that the bank is not favorable for carrying out financing examination and approval, and the imported enterprise is not favorable for obtaining financing.

3. In the actual operation process of import deposit, when the bank gets the bill of lading and signs the trust agreement with the importer, the bank only has the ownership of the goods on the upper surface and cannot actually control the flow of the goods, if the import deposit applicant is due and cannot return the import deposit remittance and the goods for various reasons, the bank has the risk of 'two losses of money and goods'.
