Study Of Information Sharing Behavior In Supply Chain Based On Evolutionary Game Theory

In the era of Internet economy,information technology is developing rapidly,and the supply chain composed of enterprises is becoming more competitive.In the current market competition environment,information has become an important competitive condition for enterprises in the supply chain.But due to problems of information redundancy and its transferring distortion etc.,it is getting increasingly difficult for enterprises to acquire effective information in supply chain.For node enterprises in the supply chain,information sharing is a good way to reduce the costs of obtaining real,effective and reliable information,and to maintain current cooperation state,which helpfully brings them into correspondence and increases their market sensitivity,thus enhancing the productiveness and competitiveness of the whole supply chain.In recent years,research on information sharing has gradually become an important part in the field of supply chain research.This thesis is based on the previous research results and correlation theories.According to the review of related literature,we firstly sort out current views on the value,mechanism and patterns etc.of information sharing in the supply chain,through which the research content and method of this thesis is settled.Combining with the characteristics of information sharing in the supply chain and previous scholars' research,this thesis selects seven affecting factors of information sharing behavior of node enterprises,including information sharing extent,information absorption capacity,information sharing costs,incentive coefficient,penalty coefficient,risk coefficient and synergy coefficient,constructs an evolutionary game model of information sharing in the supply chain based on Evolutionary Game Theory,and simulates the evolution process of information sharing in supply chain by the simulation software.This paper discusses the specific impact of the seven influencing factors on the final formation of the information sharing behavior of each node's enterprise through the solution to the evolutionary game model of enterprise information sharing in the supply chain.We find information sharing extent,information absorption capacity,incentive coefficient,penalty coefficient and synergy coefficient are conducive to the production of information sharing behavior in supply chain;while information sharing costs and risk coefficient hinds the information sharing behavior of node enterprises.At the same time,the correctness of the result is verified by the numerical examples.Based on these influencing factors and the problems in the information sharing process of enterprises in the supply chain,the thesis proposes four countermeasures:strengthening information sharing awareness,improving information absorption capacity,establishing information sharing mechanism,and promoting coordinated development of enterprises in the supply chain.Through these countermeasures,node companies in the supply chain can enhance their cooperation willingness,and the supply chain can operate healthily and harmoniously as a whole.
