效率增进、技术进步与全要素生产率增长——制造业内外资企业生产率比较

Efficiency Improving,Technological Progress and TFP Growth

运用随机前沿生产函数和1999～2006年产业面板数据,本文研究了制造业内外资企业全要素生产率和技术效率的动态变化特征。实证结果表明,内外资企业全要素生产率均不断提高,由于内资企业增速更快,二者之间的差距开始缩小。进一步的分解表明,前沿技术进步已成为全要素生产率增长的核心动力,1999～2006年前沿技术进步对内外资企业生产率增长的贡献平均约为80%和90%。

Using the stochastic frontier production function and industrial panel data from 1999 to 2006, this paper examines the dynamic features of the total factor productivity and technical efficiency of domestic and foreign enterprises in China＇ s manufacturing industry. The empirical result shows that both domestic and foreign enterprises＇ TFP continuously increase, the gap between them begins to become narrow because the TFP of domestic enterprise increases with a higher speed. Further decomposition shows that the frontier technological progress has already be- come the core motive of TFP growth. The contribution to domestic and foreign enterprises＇ TFP growth by frontier technology progress＇reached as much as 80 and 90 percentage points a year on average respectively during the years 1999-2006.
