| Over the past 40 years of reform and opening up,remarkable achievements have been made in industrialization and urbanization in China.With the rapid social and economic development and the continuous advancement of urbanization,the pressure of urban land supply has increased sharply.Thus,the economical and intensive use of land has gradually become an important subject of urban construction.In the process of gradually shifting the focus of urban construction from "increment" to "stock",the disposal of inefficiency industrial land become not only the focus of work,but also the difficult point of development.In recent years,driven by the central macro policy,local governments have successively issued policy opinions or plans related to the disposal of inefficient industrial land.However,after several years of development and practice,it is found that most of them have little effect,of which specific embodiment is,the existence of inefficient industrial land,and industrial lands turns into inefficient industrial land shortly after it sold,specially in the urban development zones with the largest number of industrial land and the most concentrated distribution.This paper starts from the actual phenomenon in which the existence of large amount of inefficient industrial land in development zones and the tardiness in the progressing governance work,taking the high-tech zone of M City as an example and selecting five representative cases of inefficient industrial land in this area on the basis of previous research.As the analysis object,this paper summarizes the current difficulties faced by the disposal of inefficient industrial land in development zones by using case analyzing and interviewing methods,and uses the principal-agent theory as a tool to analyze the causes of the current difficulties,so that corresponding countermeasures and suggestions based on the work mode and experience of typical cities can be put forward,such as Guangzhou,Shenzhen,Jinan,etc.This paper consider that the dilemma faced by the disposal of inefficient industrial land is mainly caused by the "thrust" of the disposal of inefficient land with high direct cost and low direct return and the "pull" of the development of new industrial land with low direct cost and high direct return : As the "thrust",it is difficult to dynamically identify inefficient industrial land in practice.After the identification,due to the extremely high disposal cost and few restrictive measures,as well as no index requirement for the disposal of low-utility land in the current stage,the local government is less enthusiastic about the disposal of low-utility land.As the "pull",,it is still possible to solve the problem of enterprise placement through the relatively low-cost incremental land in the development zone,and the development zone government still has some space to avoid the "hard bones".The reasons for the above-mentioned predicament include the root reason and the direct reason.The root reason is the target substitution effect in the multi-agent process of disposal of inefficient industrial land,which makes it difficult to realize the people’s entrusted demand for maximizing land benefits.The direct reason lies in the lack of local government management,which is embodied in the lack of screening and construction tracking in investment promotion,the lack of dynamic judgment of business operations in supervision,and the lack of establishment of regulations in system feedback.This paper suggests that the central government,local governments,and land-use enterprises to establish a system design to reduce the possible target substitution in the process of land use rights entrustment and agency,so as to prompt all levels to fill the management gap in time.Specifically,the central government should focus on strengthening top-level design and establish a system of shared responsibility;local governments should comprehensively deepen management,focusing on establishing a dynamic management mechanism for industrial land;land-use enterprises should emphasize corporate responsibility and keep development direction in sync with policies. |
