Impact on the Scale Efficiency of Urban Land Caused by Floating Population: Based on DEA Framework

Abstract

Due to the rapid urbanization, a large number of floating populations, who will prompt city land-use spatial scales to grow broader, rush into cities. This article is based on production factors and designs two data envelopment analysis models for evaluating urban land efficiency with population index and choose 69 counties of Zhejiang Province as decision making units to do some researches on scale efficiency in different cities. The result shows that the urban land scale efficiency level in Zhejiang Province is general high when referred to the whole situation, but regional difference is very clear. County which wants to adjust its floating population ratio to an optimal level must consider local practical situation. That is to say, local floating population offset does not have an obvious linear relationship with per capita GDP. So the government’s policy should be oriented to local conditions in making “land-population” linkage policy so as to balance city population and urban land expansion.
