Optimization Study Of Science And Technology Input Body Structure Based On The Cooperative Game Theory

Science and technology input is an important symbol of national and regional science and technology development level, and the key to make full use of science and technology to promote social progress and improve the level of people’s life. In recent years, in order to improve the level of science and technology, the governments have made the medium and long-term development plan with the core of developing high and new technology.However, an increase of the absolute number of science and technology input does not achieve a satisfactory result and it appears a phenomenon of low efficiency, severe resource waste. During 1953-2002, the contribution rate of science and technology input to economic growth in China is only 17.6%, which shows that science and technology input promotes the economic growth in China to a certain extent, but the effect is not obvious, because the main body of science and technology only stresses to increase science and technology input, and ignore the importance of the input structure of science and technology. Due to science and technology input is constant of any one region or country in a certain period, therefore, it has an important theoretical and practical significance to promote the competitiveness of the regional science and technology and economic development, that research how to determine the input in science and technology, how to allocate resources of science and technology, and establish a scientific and efficient science and technology input structure.In this paper, using the knowledge of game theory, we study the structura optimization of science and technology input in our country. Firstly, clear the definition of structure of science and technology input, and comb the relevant theories of game theory.Secondly, build the tripartite game model with enterprises, universities and government about science and technology input under the condition of complete information, and further analyze the influencing factors of the optimal structure proportion of science and technology input. Thirdly, set up tripartite game model of science and technology input of enterprises, universities and government under the condition of incomplete information,introduce the risk of the science and technology activities to into the game model as an kind of uncertainty, and further analyze the influencing factors of the optimal structure proportion of science and technology input. Fourth, set up cooperation game model of enterprises, universities and government, optimize structure of science and technologyinput using shapley value, and further analyze the influencing factors of the optimal proportion of government science and technology input structure. Finally, put forward the corresponding policy recommendations on the basis of analysis conclusions of game model to optimize structure of science and technology input in our country.
