With the development of new-type urbanization and the rapid growth of population,the government faces new situations and challenges in urban governance.Environmental health is related to the overall image of the city,is the "front" of the government.In order to improve the quality of urban governance,under the background of environmental protection upgrading,it is the general trend to transform the functions of the government,choose to purchase sanitation services from social organizations or enterprises,and implement the implementation of sanitation services through market regulation mechanism.Taking Taishan District government’s purchase of sanitation services as the research object,this paper uses literature research method,case analysis method,questionnaire survey method and other research methods to explain the relevant concepts and theoretical basis of the government’s purchase of sanitation services.By referring to the relevant literature of the government’s purchase of sanitation services in Taishan District,and interviewing relevant personnel involved in the government’s purchase of sanitation services in Taishan District.This paper describes the current situation of the government’s purchase of sanitation services in Taishan District,and finds that the purchased sanitation services in Taishan District have achieved certain results,such as improving the management level of sanitation,stimulating the development of the sanitation market,improving the quality of sanitation operations,and playing the role of assessment and supervision.And it is found that there are still some problems such as "more and more outsourcing enterprises scattered",the high cost of government outsourcing,the lack of opportunities for the public to participate in the supervision mechanism is not ideal and so on.By looking for the convergence of the principal-agent theory,the new public management theory and the current situation of Taishan District government’s purchase of sanitation services,it is found that the reasons for the existing problems are "fragmentation" of the sanitation market,the lack of "budget-conscious" consciousness of the government,the mispositioning of the role of managers,and the unsound regulatory system and methods.Then combined with the new public management theory and the principal-agent theory,some suggestions and countermeasures were put forward to improve the government’s purchase of sanitation services from the aspects of constructing the integrated mode of sanitation,improving the government’s ability to "budget carefully",improving the participation of citizens,and improving the supervision and evaluation mechanism.This paper provides theoretical reference for other cities to purchase sanitation services. |
