Technical Field
The invention relates to the field of supply chain finance, in particular to a supply chain financial platform system based on XBRL and a block chain.
Background
Supply chain finance is a financing mode for banks to link core enterprises with upstream and downstream enterprises to provide flexibly applied financial products and services.
At present, in a supply chain, core enterprises with strong competitiveness and large scale have strict requirements on upstream and downstream supporting enterprises in the aspects of trade conditions such as delivery, price, account period and the like due to the strong status of the core enterprises, so that great pressure is caused on the enterprises. Most upstream and downstream supporting enterprises are just small and medium-sized enterprises, financing from banks is difficult, and finally, a fund chain is very short, and the whole supply chain is unbalanced.
Currently, vulnerable member enterprises in the supply chain are often faced with: not only supply to core enterprises, but also bear the delay of account receivable; or to pay funds in advance to the core enterprise in the form of shop runs, securities, etc. before the sale begins. Many supply chain downstream enterprises consider "capital pressure" to be the maximum pressure they encounter in supply chain collaboration. The upstream and downstream enterprises in the supply chain share the capital risk of the core enterprise, but are not supported by the credit of the core enterprise. Although the bank wants to give credit to the enterprises, the financial institutions such as the bank and the like usually refuse to credit because of a plurality of factors such as small scale of the small and medium-sized enterprises, insufficient mortgage, difficult control of production and operation, poor resistance to economic fluctuation and the like.
