It is further preferred that the system has a user information repository for storing relevant data for users of the platform.

Still more preferably, the user information base includes holographic multidimensional information such as basic information, financial information, detection authentication information, production equipment information, test equipment information, raw material group component purchase information, research and development design information, process file information, production capacity information, inventory information, after-sales service information, performance information, manufacturing quality information, operation quality information, service quality information, safety accident information, quality evaluation information, service evaluation information, power consumption information, social public credit information, criminal record information, financial behavior information, price information, collaborative manufacturing evaluation information, and the like.

More preferably, the system carries out composite credit investigation management based on the buyer, the buyer and the transaction behavior of the transaction, and automatically measures and calculates the credit line and the financing rate to provide credit basis for the financial institution, thereby realizing the control of financial risk to the maximum extent.

The specific measuring and calculating method comprises the following steps:

and automatically measuring and calculating the ABS financing loan credit line = (A is the credit score of the seller + B is the credit score of the buyer)/200 is the sum of the goods amount 90%. Wherein A and B are used as weights and are set according to different cargo types.

For example, for a 500kV power transformer product, and a buyer is a transaction of a large national enterprise such as a national grid company, a is 0.9, and B is 0.1;

for raw material products such as silicon steel sheets and the like, and the buyer is a power transformer factory, A is 0.4, and B is 0.6;

a, B is set by the financial institution itself based on the credit investigation service platform data of the system or in combination with the credit investigation service platform data of the system and other data of the financial institution. The sum of A and B is 1. The financial institution assigns A, B a certain weight proportion according to the actual situation, thereby automatically measuring and obtaining the loan credit line. The larger the value of A is, the larger the influence of the credit of the enterprise A on the credit line is, and the larger the risk of the enterprise A is; the smaller the value of A is, the smaller the credit risk of the enterprise A is, and the smaller the influence of the enterprise A on the credit line is; similarly, the larger the value of B is, the larger the influence of the credit of the enterprise B on the credit line is, and the larger the risk of the enterprise B is; the smaller the value of B is, the smaller the credit risk of the enterprise B is, and the smaller the influence of B on the credit line is.

Financing rate = (a + seller credit + B + buyer credit)/200 + financial institution ABS financing discountless rate;

wherein A and B are used as weights and are set according to different cargo types.

a, B is set by the financial institution itself based on the credit investigation service platform data of the system or in combination with the credit investigation service platform data of the system and other data of the financial institution. The sum of A and B is 1. The financial institution assigns A, B a certain weight proportion according to the actual situation, thereby automatically measuring and obtaining the financing rate. The larger the value of A is, the larger the influence of the credit of the enterprise A on the financing rate is, and the larger the risk of the enterprise A is; the smaller the value of A is, the smaller the credit risk of the enterprise A is, and the smaller the influence of the enterprise A on the financing rate is; similarly, the larger the value of B is, the larger the influence of the credit of the enterprise B on the financing rate is, and the larger the risk of the enterprise B is; the smaller the value of B is, the smaller the credit risk of the enterprise B is, and the smaller the influence of B on the financing rate is.

Fixed-asset mortgage credit line = corporate credit/100 mortgage assessment value 90%;

financing rate = business credit/100 financial institution mortgage loan discounted interest rate;

the credit loan credit line = the enterprise credit/100 the maximum credit loan line of the financial institution;

financing rate = business credit/100 financial institution credit discounted interest rate.

More preferably, the system adopts the credit scores and credit grades of the buyers and the sellers to be displayed online in real time, and provides auxiliary decisions for mutual selection of two transaction parties, so that the transaction efficiency is improved, and a credit transaction environment is constructed.
