Abstract:

Improving the use efficiency of construction land is an inevitable way to achieve sustainable use of land resources. On a basis of a brief analysis of construction land utilization characteristics in Chongqing, C2R model of DEA was employed in this paper to measure the technical efficiency of construction land use in ecnomic growth of each of its 40 counties during 2000-2008. Results showed that the spacial differences of construction land use efficiency in economic growth were consistant with that of regional economy development and Chongqing’s urban system expansion; the period of 2000-2004 saw a slight increase of overall efficiency, but it experinced a decrease during 2004 to 2008, which kept consistency with the evolution of Chongqing’s industrial structure and construction land’s supply and demand structure, it was also found that slacks of labour and construction inputs exsited in most counties, indicating a dissatisfactory input element configuration. Proposals of rasing construction land use efficiency was given out according to the particular situation of Chongqing.
