A Study Of Credit Mechanism In Chinese Construction Market Based On The Complex System Theory

With the reform and opening in China, disorder and credit shortage in construction market become increasingly severe and harmful, which not only add production cost and risk in construction corporations, ruin social moral, but also decrease the efficiency of resource use in the whole society, and became bottle-neck to the productivity improvement. A series of credit institutions and measures have been put forward by Chinese central and local governments, but they are focused on one aspect of credit issues, cannot solve the problems fundamentally. So, it is urgent to form the "mechanism improvement" conception in view of system, dynamics and evolution, devote to credit mechanism design in special stage of construction market, and promote the building and improvement of credit institutions and credit system.To solve the problem of credit disorder and mechanism shortage in construction market, this dissertation puts complex system theory, mechanism design theory and evolution and game theory into use to analysis the form principle, connotation and complexity characteristic of credit mechanism in construction market and to discuss its effect principle, mode and function. This paper also analyzes evolutionary characteristic of credit mechanism, such as illogic evolution, unbalanced mechanism and axiology shortage, and reveal the evolutionary path and development rule on the precondition of the situation and credit status of Chinese construction market. This paper also analyzes and imitates the credit mechanism in construction market by using system dynamics theory, brings forward relevant policy suggestion on credit mechanism design.The main achievements include: puts forward the "up-and-down" mode of information sharing mechanism and "joint rejection in market" mode of incentive restriction mechanism by combining credit management experience in west countries and actual situations in our construction market; builds evolutionary game models with two bodies and multi-bodies to discuss their convergence conditions and influence factors and put forward the evolution path of credit machanism; based on System Dynamics and status of construction market, builds system dynamics model of credit mechanism in construction market, makes imitation analysis and long-term forecast on credit issues, and takes relevant policy test and analysis; puts forward goal, reference, basic principle of credit mechanism design in construction market and provides relevant policy suggestions on improving credit mechanism, accelerating institution construction and promoting credit system based on the status and special situation of our construction market.The innovation points include: extends the view of credit mechanism research by the application of system complexity theory and evolution theory; puts forward academic study frame of credit mechanism based on the analysis on the form principle, connotation, complexity characteristic, effect principle, mode and function of credit mechanism; reveals evolutionary rules of credit mechanism in the construction market by using evolution and game theory; brings the conception of "credit chain" and "credit entropy" into the credit mechanism research, enriching the quantitative indexes and methods on credit mechanism research; builds systemic model of credit mechanism, simulates and imitates its evolutionary processes, and examines relevant policies by means of "policy laboratory ".With the improvement of governmental inspection and management by and information opening laws, public information sharing platform and information serving organizations have been established and improved. In the same time, incentive and restriction measures such as united database of information reporting system, credit behavior revelation in public, credit evaluation, and engineering assurance have been tried out and spread throughout the country. Thus, credit mechanism has been improved continually and credit system in our construction market been promoted to be information sensitive and incentive compatible.
