In the process of China’s urbanization development, the manifestation of rural land value caused by the land expropriation arouses the opportunism behavior trends of the peasants, however, the unclear rural contracted land right and the default of rural “legal authority” make rural contracted land system difficult to restrict the opportunism behavior of the peasants. Under the popularization of the opportunism, the “boundary dispute” emanating from plundering the valueadded of the land between the peasants has its necessity. China should continue to verify the contracted land right of the peasants, establish the rural property right system with tangible allocation and easy implementation for rural land, make laws and regulations for restricting the opportunism behaviors of the peasants through the penalty, set up clean administration image of governmental departments, raise legal and cultural quality of rural residents, let the peasants follow the rural contracted land system and regulations in their heart, realize the experience effect of the laws and regulations and set up rural social “authority” in order to effectively control present rural “boundary dispute” in China.
