From the macro-perspective, seven indexes including urban land use, township economic development stage, urbanization and township enterprise structure are selected. From the micro-perspective, 12 indexes including location situation, governance capability and economic developmental level at village level are selected. Besides, the multiple factors evaluation model is established. Taking implementation items of cooperated rural households in Hubin Village, Baijia Town of Dianjiang County as an example, the implantations items are analyzed by using the comprehensive evaluation model and the evaluation results are in accordance with actual situation. The effectiveness of the comprehensive evaluation method is proved. However, affected by the limited application scope of implementation model, insufficient policy and one-sided farmers' participation, in order to avoid copying the successful experience of completed pilot blindly, farmers are suggested to adopt the implementation model of cooperated rural households.展开更多
