Abstract: The lag of farmer workersapos; citizenship process is a major obstacle to the quality and speed of new urbanization in China, and the high cost of citizenship is also the root cause of the lagging process. Based on the stakeholdersapos; perspective, this paper analyzes the cost-sharing mechanism of farmer workersapos; citizenization by using game theory, establishes the pure strategy Nash equilibrium matrix for the central government, local government, enterprises and farmer workers and finds the optimal Nash equilibrium solution. According to the research, the central government and local government should share the common cost of citizenship. For example, the central government should adopt the encouragement strategy to increase the general public expenditure and the transfer payment, and the local governments cooperate with each other to promote the farmer workersapos; citizenization process. Enterprises and individuals are the main participants and beneficiaries of the farmer workersapos; citizenship. They mainly undertake the non-public costs of urbanization. Enterprises should share the private costs of farmer workers through the establishment of a management system of "equal pay for equal work, equal work for equal time and equal work for equal rights", share the private costs of farmer workers, and improve the ability to citizenship.
