The Price Game Model Analysis And Application Research Of A Kind Of Oligarch Insurance Market

After decades of development, China’s insurance market has entered the state of mamy oligarchs occupy the market, and have the competition in different insurance product. How to occupy the initiative in the complex competition, and have the advantage in the process of market game, has become the important issues which have a great influence on the decision-making of Chinese oligarchs insurance company development in future. Based on the research achievement of the scholars of the domestic and foreign, this paper put the game theory and chaos theory into the use of Chinese insurance market oligarchs’ competition. and establish the corresponding game model, then have an analyses on the inner complexity of the system. Through the numerical simulation, gives the corresponding results and the economic management in the sense of analysis, which provide a certain reference for the Chinese insurance market pricing game problem.1. Have the introduction of the game theory and chaos theory, and analyzes the necessity of the use of game theory and chaos theory in the research process of Chinese insurance market’s inner complex characteristics according to the Chinese oligarchs insurance market’s actual situation. Based on this, this paper introduces a series of chaotic model and economic model, and make an improvement to traditional Bertrand model as the theoretical basis of this research, will the price index as the variables in the process of game, which conform to actual situation of China’s oligarchs game insurance market.2. Establish the repeated game model with prices as a decision variables, and then have an analysis to the complex dynamics behavior of the system, obtained a series of complete conclusion. Through numerical simulation we get its bifurcation diagram, Lyapunov index diagram, the strange attractor and initial value sensitivity, all of which is the visual diagram of complex dynamic behaviors, and have the results described. The result shows that due to different price adjustment speed, the oligarchs have different chaotic state in the game process, the game equilibrium price stability changed. According to the conclusion, the instrument oligarchs should accurate judge the game environment, expand the stability area of the Nash equilibrium, narrowing the scope of chaotic. Then we get the conclusion of strengthen and extended the macroeconomic market regulation in the process of competition.3. Improved the repeated game model with the market share factors joined, and then have an analysis to the complex dynamic behaviors of the new system, shows the corresponding complex dynamic behavior diagram. Through the analysis and comparison we can see that with the introduction of related factors, the modification of the system’s dynamics behavior tended to complicated state, the market competition results will become more chaos and unpredictable. The result we get further shows the importance of government to strengthen the macroeconomic regulation. In order to ensure the order of oligarchs insurance market competition, the oligarchs need to control the parameters, clear the related factors, strengthen macroecenomic regulation, the result provide some guidance to the future development of Chinese insurance market.
