China's public institutions originated from the planned economy.With the establishment of market economy,the public institutions could not adapt to the situation.The reform and development are the main focus of research and policy choice.Among the problems of public institutions,there exists unclearness of function definition,rigid of system,lack of regulation,low of efficiency,inadequate of competition.To solve these problems,China proposes the idea of classification.But the classification reforms abide by the logics of state and market,which make the reforms slowly.Based on the design and experiment of epistemology,the reform of china public service unit reforms should substitute the state and market logics for the non-profit logic.Through the logic of non-profit,the public institutions can maintain the public interest and promote the efficiency of public service provision.The reforms of public institutions can be classified into three types,namely quasi-government units,public owned non-profit organizations(basic public services),and public owned non-profit organizations(alternative public services),and society owned non-profit organizations.
