We divide the local governments into the central government’s agent，“corporatism” economic man and profit-seeking manager of political power. Through constructing an analysis framework which consists of central government，local government，firm and consumers，the mechanism of government and firm’s behavior logic influences the implementation of regulation after the central government has set the policy of Minimum Quality Standards regulation is analyzed. We show that when local government acts as a “corporatism” economic man，firm’s utility and local governments’ utility would increase，meanwhile，the degree of firm’s compliance，consumer utility and the level of social welfare would decrease in comparison with the situation when local government acts as a central government’s agent. When local government acts as a profit-seeking manager of political power，firm’s utility and local government’s utility are the highest，and the degree of firm’s compliance，consumer utility and the level of social welfare are the lowest among the three situations. Hence，only analyzing firm and local government’s specific behavior logic accurately can we forecast and appraise the real degree of firm’s compliance and social welfare effect preferably.
