Description
Technical Field
The invention relates to the technical field of supply chain finance, in particular to a receivable account and debt right transfer system and a receivable account and debt right transfer method based on a regional chain.
Background
Accounts receivable are important assets of various current economic subjects, especially small and medium-sized micro-enterprises. According to statistics, the annual account amount of enterprises in China at present is 80 trillion, and the inventory is 20 trillion; the local government has reached 20 trillion debt stocks in 2015, with a significant proportion of them being accounts receivable by the enterprise; the research report of the national finance and development laboratory of the Chinese society indicates that the total amount of Chinese debt reaches 168.48 trillion in 2015, the global social leverage (the ratio of equity capital to total assets in an asset liability table) is 249%, and a large amount of receivable accounts urgently await the survival of innovative ways.
Based on market demands and convenience of modern information technology, many business methods and matching system technology research and development around accounts receivable, accounts payable and debt as cores appear, but the current business platform of accounts receivable and accounts payable basically aims at checking accounts receivable, and comprises the purposes of warranty, supply chain finance, debt and debt management, accounts receivable and financing, P2P and the like, and the business platform of accounts receivable and accounts payable has the functions of checking accounts receivable to a certain extent through a mode innovation, so that the accounts receivable and financing are realized or the management level of accounts receivable is improved.
Although these innovative modes build an accounts receivable management, financing, transaction or intermediary platform by virtue of the convenience of information technology, the management, financing or transaction intermediary service is provided for accounts receivable. However, these business platforms have drawbacks: firstly, a large amount of money funds are needed as a support, but most of the funds are reserved in hands of core economic main bodies after passing through the management mode and are used for expanding production operation and investment scale per se and consolidating the core status of an industrial chain, and only part of the funds are transferred to hands of small and medium-sized enterprises or entity economic enterprises in forms of confirmation of core debtors, money payment or supply chain and the like. Secondly, accounts receivable and capital are arranged at two ends directly connected with the business platform, a large amount of debts and triangular debts exist in the middle section, the middle section cannot be completely dissolved in a cash and financing mode, and even the middle section cannot play the role of the value attribute of the accounts receivable, so that the liquidity requirement of the economic main body of the market for developing economic activities is met, and thirdly, the environment for storing data information is not safe enough and is easy to be utilized by lawbreakers.
