我国制造业技术进步、技术效率及区域差异——基于DEA方法的实证研究

利用Malmquist生产率指数方法，对我国29个省的制造业在1999--2005年间的全要素生产率（TFP）的变化进行了测算，把TFP的增长构成分解为技术进步和生产效率变化两个成分，并对其区域差异进行了分析，最后对省际制造业TFP进行了趋同分析。结果显示：我国制造业TFP的增长主要是由技术进步推动的，当技术进步促进TFP提升时，总会受到生产效率下降对TFP增长的抑制影响；区域间技术进步及技术效率存在较大差异，省级制造业TFP存在条件β收敛。

Technical Progress ,Technical Efficiency and Regional Difference of Provincial Manufacturing Industry:Empirical Research Based on Data Envelopment Analysis

Through the Malmquist index approach based on data envelopment analysis（DEA）, this paper measures total factor productivity （TFP） of provincial manufacturing industry in China from 1999 to 2005. The structure of TFP is decomposed into technical progress and techni- cal efficiency. And it analyzes the difference of regional productivity and the TFP convergence of interprovincial manufacturing industry. The result shows that the growth of TFP of manufacturing industry in China is mainly promoted by technical progress,the decline in technical efficiency has inhibitory effect on the growth of TFP,and there exists large variations among different regions and conditional β convergence in provin- cial manufacturing industry.
