Research on Effectiveness of Urban Construction Land Use Structure Based on DEA

With the acceleration of urbanization process, the increasing land resource constraint has become a primary issue in the process of Chinese economic and social development. Since the social, economic and ecological benefits are closely related to the land use structure, reasonable and effective use of land structure is a valid way to ensure the sustainable exploitation of land resources. This paper carries out a contrastive study of urban construction land use structure efficiency among 26 typical cities in our country according to the urbanization rate, makes use of data envelopment analysis to deal with the related data in these cities in the years from 2007 to 2011, and then focuses on Tianjin issues to find out that the adjustment of investment combination among all kinds of construction land makes the allocation of resources optimized, which is an inevitable trend with the improvement of urbanization rate. The study also concludes that it can avoid the waste of land resources effectively, promote economic growth and lead to the development of urbanization through the reasonable optimization of urban construction land structure. For Tianjin, it should try to reduce the land area for public facilities, industry and storage to achieve economic growth. In the end, it draws the conclusion that the country has paid more attention to the construction land structure adjustment by the contrast between the newly Code for Classification of Urban Use and Planning Standards of Development Land in 2012 and the standards implemented in1990.
