农民经济合作：演化轨迹与发展趋势

农民经济合作的演化经历了传统时期社会网络内的合作、20世纪50年代政府主导下的合作和20世纪80年代后出现的专业性经济合作三个阶段。不同合作阶段在社会经济结构、合作纽带、主导力量和合作路径等方面呈现不同的特征。从合作的演化趋势看，社会网络内农民合作将长期存在，但朝着规范的方式演进；政府对农民合作的推动力量逐渐隐蔽，但仍然发挥着重要的作用；农民主导的专业性经济合作成为主流。

Farmer＇s Economic Cooperation： The Evolution and Development Trend

Farmer＇s economic cooperation has undergone three stages：cooperation within the traditional social networks, cooperation dominated by the government in the 1950＇s, and the professional economic cooperation in the 1980＇s. There are different characters of cooperation at different stages because of the economic and social structures, tie of cooperation, and the dominant force and cooperative path. From the perspective of evolution trend, cooperation within social networks will persist in the evolution of the specification; the increasingly subtle driving force of the cooperation from the government still plays an important role in the co- operation; and farmerled professional economic cooperation will become mainstream.
