中文摘要：

基于SBM模型分析了2002-2012年中国6个主要经济区城市工业用地利用效率的空间差异，然后用Malmquist指数揭示工业用地全要素生产率（Totalfactorproductivity,TFP）的动态变化，并对其做收敛性分析。结果发现：珠三角和长三角经济区城市工业用地利用效率较高，但TFP却出现衰退趋势；京津冀、成渝、关中一天水和中原经济区城市工业用地利用效率较低，但TFP却出现增长趋势。各经济区都存在工业用地粗放利用、工业劳动力过剩以及工业经济产出不足的情况。工业用地TFP的收敛性分析表明仅有长三角经济区存在俱乐部收敛现象；各经济区都存在条件收敛。影响变量的估计结果表明，为提高工业用地TFP，长三角经济区需要适当减小工业劳动力和工业产值占总体劳动力和经济产值的比重，珠三角经济区需要提高城市化率，京津冀经济区需要适当提高工业产业层次并积极引导转移工业剩余劳动力，成渝经济区需要适当减小工业劳动力比重；所有经济区都需提高工业用地利用强度。

英文摘要：

Based on SBM model, this paper first analyzes the spatial differences of urban industrial land use efficiency in the six main economic zones of China. Then it analyzes the dynamic variation in total factor productivity （TFP） of urban industrial land by using Malmquist index, and examine the convergence of urban industrial land. The results show that the Pearl River Delta Region and Yangtze River Delta Region have higher urban industrial land- use efficiency and show downward trends in TFP, while the Beijing-Tianjin-Hebei Region, Chengdu-Chongqing Region, Guanzhong-Tianshui Region and Central Plains Region have lower urban industrial land-use efficiency and show upward trends in TFP. The extensive use of industrial land, industrial labor surplus and shortage in industrial economic output exist in all six major economic zones of China. Only the Yangtze River Delta has club-convergence, and all the economic zones show the conditional convergence. The estimation results of influence variables show that, in order to raise urban industrial land＇s TFP, the Yangtze River Delta should reduce the percentage of industrial labor force in total labor force and the percentage of industrial output in total economic output. The Pearl River Delta should raise urbanization rate, the Beijing-Tianjin-Hebei Region should raise the industrial level and transfer industrial surplus labor, and the Chengdu-Chongqing Region should also reduce the percentage of industrial labor force in total labor force. The industrial land use intensity should be increased in all the six major economic zones.
