Research On Supply Chain Competition Based On Asymmetric Information And Contract

With the rapid development of science and technology, in the context of the global economy increasingly integrated, enterprises in the market economy to be successful, should not only focus on their structure and benefit, must pay more attention to their competitors, always doing the competition countermeasures is very important. In real life, in order to obtain a favorable position in the competition, each enterprise hide some of their information, to get more revenue, but it can not only effectively increase their profits, but will damage the overall efficiency of the supply chain, so the information sharing is an important topic in the research of supply chain,and supply chain contract is an effective way to solve the information asymmetry, so under the conditions of asymmetric information and contract, researching in the supply chain competition is very meaningful.In this paper, one-to-one structure of the traditional supply chain is expanded to a two-suppliers-and-a-manufacturer supply chain, the manufacturer's processing cost information and manufacturer's demand information is asymmetric, we use different contracts such as profit sharing contract and two-part tariff contract to study the supply chain competition problem. In the research process, comprehensive game theory, supply chain contract and operation research and other related knowledge is used to model and solve.First of all, through the study of domestic and foreign research results, summed up the supply chain competition, asymmetric information existing research situation,supply chain contract in supply chain management application status and principles.Secondly, in this paper, under the profit sharing contract, we analyze whether there is a second supplier to participate in the competition. When there are two suppliers competing with the manufacturer, we discuss the information symmetry of the manufacturer and the two suppliers separately, the asymmetric information between the manufacturer and one supplier, the information asymmetry between the manufacturer and the other, and the information asymmetry between the manufacturer and the two suppliers. Thirdly, we discuss the optimal decision whether the information is symmetrical or not between the manufacturer and the two suppliers.Finally, numerical simulation is carried out by MATLAB software to verify the correctness of the results.
