中国信息制造业全要素生产率变动、区域差异与影响因素研究

Research on TFP Change,Regional Disparity and Affecting Factors of China's IT Industry

本文使用基于DEA的非参数Malmquist指数方法研究了1996—2005年中国各地区信息制造业的全要素生产率(TFP)的变动、区域差异以及影响因素。研究结果表明:中国各地区信息制造业的TFP的平均增长率为8.6%,其中技术进步是TFP增长的主要动力;东中西部地区之间TFP增长存在显著差异,且技术效率存在收敛趋势;人力资本、工业化、国有企业和外资企业比重是拉动TFP增长的显著因素,而企业平均规模和聚集效应则对其有负面影响。

This paper applied DEA-Malmquist Index to measure the total factor productivity （TFP）change of China＇s IT industry during 1996--2005. The main conclusions are as follows. On the whole, TFP of IT industry is increasing at 8.6% per year during the sample period, and the main source of TFP growth is technical progress＇s advance. The regional disparity of TFP in China＇s IT industry does exist, The technical efficiency reflects remarkable convergence during the sample period. While the reasons of TFP growth include human capital, industrialization and enterprise ownership, the average scale and congregation have negative effects on TFP growth.
