Research On The Construction Of Personal Credit Investigation System In China's Internet Finance

In recent years, Internet Finance(ITFIN) is developing rapidly in our country, more and more people are involved in it to enjoy convenient financial service. ITFIN is the combination of Internetrelated technology and financial industry, compared with the traditional financial industry, although there are differences in the form, but its essence is still the financial, so, it still has to face the various risks that faced by traditional financial industry. As a traditional financial industry, the basic risk is credit risk, the situation in the ITFIN is more severe, because the inclusive nature of the ITFIN and the global nature of the Internet expand the degree of impact of personal dishonesty and scope of influence. The most effective way to avoid personal credit risk is to build a perfect personal credit investigation system.China's personal credit investigation system started late, many aspects are still not perfect, especially in the era of ITFIN, the situation of personal credit risk will be more severe, so we urgently need to build a perfect ITFIN personal credit investigation system.In this paper, the Asymmetric Information Theory and the Transaction Costs Theory are used to explain the theoretical basis of building personal credit investigation system, and the Game Theory is used to explain the necessity and importance of personal credit investigation system. Then, starting from the construction of the status of China's ITFIN personal credit investigation system, we point out China's ITFIN personal credit investigation system construction problems. The method to solve the problem of personal credit is the most important part of ITFIN personal credit investigation system, which is different from the traditional method to solve the problem of personal credit, this paper studies the new method to solve the problem of ITFIN personal credit(Big Data). Based on the above analysis and research, at the same time compare the ITFIN personal credit investigation system construction mode of the mainstream countries in the world, this paper puts forward the ideal model of construction of China's ITFIN personal credit investigation system. Finally, we put forward some suggestions on the problems in the construction of ITFIN personal credit investigation system in China.Through the research on the construction of China's ITFIN personal credit investigation system, we have reached a few conclusions: Firstly, personal credit investigation system as a restraint mechanism in the personal credit game, which makes both of the game out of the "Prisoner's dilemma" to achieve Pareto Optimality. Then, ITFIN should use the method to solve the problem of personal credit by big data, the method is faster, more convenient and more accurate. Finally, the ideal model of construction of China's ITFIN personal credit investigation system should be based on the personal credit system of The People's Bank Of China(PBOC), establish the ITFIN personal credit investigation subsystem.
