A Research Of Market-oriented Credit Mechanism In Construction Project

In the engineering construction projects, quality and safety accidents caused immeasurable loss and also produced waste of resources, much due to the breach behavior. The main reason for the lack of credit is that system is not perfect and lack of credit management system in the construction engineering. At present, the study of credit problems for construction projects is still in the analysis of the causes of credit risk and credit evaluation methods of theoretical research stage. There are lots of new and highlighted gradually problems in the process of policy implementation.This paper is to research on construction engineering credit mechanism. Thus, each credit body’s integrity self-discipline will be increased and whole credit level of society will be great promoted. Through the analysis of research status at home and abroad, we can analyze credit mechanism in the construction engineering. On the basis of system dynamics theory, this paper uses STELLA software to simulate construction market credit system. On the other side, it also expounds the incentive-restricted mechanism from mechanism design theory.The paper builds a game model between owners and contractors on the basis of the views and methods of evolutionary game theory. Through the study of the project payment default in construction engineering, the paper discussed the evolution process of credit mechanism in construction engineering market and also analyzed game behaviors and its evolution regularity.Credit mechanism which is based on the idea of complex system simulates the process and predicts its developing trend, and will be a theoretical evidence of the measures. Comparison and analysis are made between the government-led construction engineering market credit system and market-oriented construction engineering market system with the help of STELLA. The results show that attaching great importance to the role of credit service agencies in the market will help to improve the credit level of construction engineering market. Besides, the paper build a base model about credit system "simulation lab”, which have a great influence on scenario analysis of credit system in construction engineering market.Finally, with the introduction of credit service agencies, the credit mechanism order governance framework was put forward and the problem which is not been fixed between government and market has also been solved. Meanwhile incentive mechanism and constraint mechanism was put forward, which means credit service agencies will be dominant role and the level of the each credit body in construction market will be developed, which is based on the government regulation and the incentive and punished measures. Combining with the characteristics of engineering construction projects, the relevant suggestions are given to the incentive and constraint mechanism, so the credit service organizations in our current country and their status have been ensured.
