Under the conditions of market economy, farmers scattered, autonomous, to the pursuit of self-interest maximization for the purpose of production and management decision-making, driven by economic interests tend to choose to grow high comparative effectiveness of economic crops, government regulation of agricultural production a major The goal is to maintain a certain amount of grain crops, crop production and management, both sides have some contradictions. How to coordinate the relationship between the two compatible as well as a win-win for the two sides to achieve goals is a major issue for researchers and concerned parties. Farming of this article to the outskirts of Shanghai, for example, select several typical crops, research the contradictions of the scale and efficiency of agricultural production, the contradictions in the government and farmers in the agricultural operation, answered the trade-offs between the scale and efficiency of crop production and management contradiction coordinating the response of government and farmers contradictions. Paper is divided into seven parts, the first chapter, the introduction, mainly on the purpose of this study, the meaning and Research, as well as the work of the study process; second chapter, the theoretical basis for this study involved the basic theory, scale reward theory and game theory; Chapter, the basis of the data collection and collation, the methods and results of the data sources, as well as organize the raw data; Chapter, cost analysis, and analysis of the cost structure of the crop, and compare the different crop costs and the cost of similar crops; Chapter, performance evaluation, and analysis of the operating performance of the crop, based on comparing the performance of different crops vary; Chapter VI, game theory analysis, the basis of the cost analysis and performance analysis game model built on crop production and management, through the analysis of the course of the game, strike game balanced business strategy under different conditions; Chapter VII, countermeasures and suggestions, and discuss how to use the results of this research to guide production practices and operating decisions. The analysis found that: (1) different crop production and management performance difference between the larger, represented by rice vegetable cash crops completely different economic characteristics of food crops in terms of production costs, operating performance; (2) The economic benefits of rice is much smaller than its social benefits, with a quasi-public nature of the product; (3) of rice, vegetables and other to show some economies of scale in the production and management, but with the crops of their own characteristics; (4) in the assumption , the farmers and the government is not easy to reach the game equilibrium, risk of failure of agricultural policies.
