基于契约博弈模型的农业产业链纵向协作分析

农业产业链纵向协作模式的优化演变有利于实现产业链整合，促进产业链参与主体利益互补机制的建立。根据实地调研情况，在分析市场交易、合同、合作社以及纵向一体化等多种纵向协作模式的运作方式及其优缺点的基础上，通过构建契约博弈模型对产业链纵向协作模式优化进行博弈分析。结果表明，合同模式并不是一种稳态的纵向协作模式，而合作社模式是合同模式的改进，是一种更为有效的纵向协作模式，并由此提出促进农业产业链纵向协作模式发展的相关政策建议。

Analysis on Longitudinal Cooperation Mode of Agricultural Industry Chain Based on Contract Game Model

The optimization and evolution of longitudinal cooperation of Chinese agricultural industry chain can help realize industry chain integration and promote the establishment of benefit complementary mechanism of industry chains.Based on the ways of operation and advantages and disadvantages of many kinds of longitudinal cooperative modes such as market transactions,contracts,cooperative and vertical integration,this paper analyzes the optimization of longitudinal cooperation by building contract game model.The result shows that contract mode is not a steady state longitudinal mode of cooperation,the cooperative mode is the improvement of contract mode and a more effective longitudinal cooperation mode.Therefore,this paper puts forward some relevant policy suggestions on how to promote the vertical cooperation mode in the development of agricultural industry chain.
