Study on the Regional Differences of Construction Land Efficiency in Sichuan Province

摘要

Using data derived from Sichuan Statistical Yearbooks and investigations of land-use change, the present research does a DEA-model study of regional differences in overall input-output efficiencies of construction land in the economic development of Sichuan province between 1999 and 2012. It finds that though in all land-use regions of the province the overall input-output efficiencies of construction land maintain a comparatively high standard, in some regions they are not in complete accordance with local economic development level. In addition, there are obvious disparities in the change patterns of the overall input-output efficiencies in different land-use regions. This paper then suggests that the function of adjustment, which the optimal allocation of construction land can play, should be brought into full effect to enhance regional socio-economic development, and that the allocation of construction land should be based on a comprehensive analysis of overall efficiency.
