Abstract: Corporation and Forestry Cooperation Organization and Farmer model is an important forestry management form after the reform of collective forest property right system. Using method of evolutionary game theory, a replication dynamic model of the cooperation relationship between corporations and farmers is constructed in this paper. Evolutionary regulation of cooperation relationship of corporations and farmers is also analyzed. Results show that the cooperation will change evolutionary paths because of the change of both sides’ initial cooperation desire, cooperation benefit and cooperation cost. According to the analysis results, corresponding suggestions are put forward.
