中文摘要：

大农和小农在资源禀赋方面存在的异质性使得双方在合作社的生产活动和经营管理活动中均存在博弈行为。本文利用完全信息动态博弈理论对大农与小农博弈过程进行分析，双方博弈的结果往往是“大农得益、小农失利”，继而形成了“大农吃小农”的现实。为达到帕累托最优，实现大农“不盘剥”、小农“管理”的博弈均衡，必须建立完善的合作社奖惩激励机制、加大政府对规范型合作社的资金支持力度，降低大农与小农的异质化程度来缩小双方在资源禀赋上的差距，形成大农与小农相互合作、共同受益的局面以促进合作社的持续发展。

英文摘要：

The heterogeneity of the big-＇farmers and small-farmers＇ resource endowments makes the two sides have game behavior in the cooperative activities and management activities of the cooperatives. In this paper, the dynamic game theory of complete information is used to analyze the process of big-farmers and small-farmers. The result of the game is that the big-farmers is getting benefitted and the small-farmers is losing interest, and then form the reality of ＂big-farmers eating small-farmers＂. In order to achieve the best of Pareto, it is necessary to establish a perfect cooperative reward and punishment mechanism, increase the government＇ s support for the normative cooperatives, and reduce the large heterogeneity, becoming the situation of mutual cooperation and common benefit between big-farmers and small-farmers in order to promote the sustainable development of coop- eratives.
