Abstract: Through the analysis of the role of village cadres in collective land management, the operation mechanism of collective land management is discussed. The appreciation of power provides a dynamic foundation for the land management of village cadres. By mobilizing individual social relations and working with local governments, village cadres raise private and government resources and build a resource base for the land management. Due to the social security function of land for peasants, collective land market management behavior will inevitably lead to uncontrollable risk, and village cadres transfer the market risk to governments by self-preservation strategy, which will produce political risk. In order to restrain the economic risk behavior of the land management of village cadres, the supervision of village cadres and local governments should be strengthened in the law.
