英文摘要：

The purpose of this study is to establish a behavior mechanism of local government and land-lost peasants during farmland-acquisition. Suggestions are provided to counter the conflicts of farmland-acquisition. The method of the game theory and case analysis were employed.The results from theoretical analysis and empirical evidence indicate that improving consciousness, reducing cost of peasants＇ rights protection and strengthening punishment of local government＇s illegal behaviors in farmland-acquisition can improve land-lost peasants＇ income and control local governments＇ illegal acquisition behaviors effectively. It concludes that propagating legal knowledge of land acquisition to land-lost peasants, establishing land-lost peasants＇ organization and building their interest claiming mechanism can reduce the rights protection cost; building land supervised system which includes ex-ante prevention, mid-stage monitoring and ex-post punishment can reinforce comprehensive constraint of local governments＇ behaviors in farmlandacquisition.
