中文摘要：

农户互动网络具有嵌入性、多功能性、动态性和传承性等特征。文章针对农户互动网络的动态性,提出农户互动网络的四阶段演化模型,并以河南省杞县孟寨村为例对其进行案例研究。文章认为,初始阶段,互动内容单一、规模小且结构离散;单核阶段,个别农户的能量得到迅速积累,与周围农户的能量呈现显著的差异,并成为农村社区的＂明星＂农户;多核阶段,互动网络出现多个核心,互动规模较大,但网络结构混乱、无序;高水平互动阶段,互动规模大,能量和能量流呈现等级、有序的结构。

英文摘要：

Farmer interaction network has some features such as embeddedness,multifunction,dynamics and inheritance.According to the dynamics of farmer interaction network,this paper brings forward the four-stage evolutional model of farmer interaction network,and in the case of Mengzhai village,Henan province,illustrates this model.The result shows that in the initial stage,farmer interaction network has simple interactive content,small scale and discrete structure,that in the one nuclear stage individual household＇ energy is rapidly accumulated,represents significant difference with surrounding farmers,and becomes ＂star＂ farmer in the rural,that in the several nuclear stage,the scale of interaction network appears larger than in one nuclear stage,and interactive network structure presents confusion and disorder,and that in high levels of interactive stage,farmer interaction network has larger scale,power and energy flow,and presents orderly structure.
