| Public interest is the core value of the pursuit of public administration. The theory and practice of public interest face multiple complexities during the transition period in China. On the one hand, with the development of political democratization and civil rights awareness growing, the public interest have to face the extrusion and digestion from the individual interests; on the other hand, as there is a long way to go in the political reform, the market economy system is far from perfect as well, executive power is still firmly grasping the scarce resources, the public interest can easily be equivalent to the national interests and the government interests. Under such situation, public interest becomes an excuse for infringement of personal interests by public authority. Serious differences on the connotation and denotation of public interest theory, as well as the long-term absence and "unstructured" about the concept of the public interest in legislative and public policy practice can not be ignored. This article focuses on the urban housing expropriation areas, which public and personal interests intertwined and conflicts most concentrated, as well as the social groups protest.
