Enterprise Credit Chain Risk Transmission Theory Model And Its Application

The main research of this paper is one aspect of the chief studies of the National Natural Science Foundation project as "General project risk element transmission theory model and its application". This paper put an emphasis on enterprise credit chain risk transmission model based on risk element transmission theory. Firstly, this paper explains the risk element transmission theory, and then this paper proposes enterprise credit chain risk element transmission model. And then enterprise credit chain is broken down into capital credit chain, supplies credit chain and sales credit chain. Probability theory, fuzzy Markov chain, and game analysis are respectively used to analyze risk element transmission on the three chains. Finally, total differential method is used to establish the analytic model of enterprise economic evaluation indicators, and the analytical expression of enterprise credit chain risk element transmission is obtained, which impact economic evaluation indicators. In this paper, Matlab mathematical software is used to draw the probability density function of risk distribution. The model is verified to be scientific, reliable and operable.
