中国地区工业知识生产效率测算

Calculation of Knowledge Production Efficiency of Industry across Regions of China

文章运用1996-2003年我国29个省(自治区,直辖市)的大中型工业企业面板数据,以新产品开发项目数衡量创新产出,以研发资本存量和研发人员表示创新投入,采用数据包络分析和随机前沿分析方法,对我国地区工业的知识生产效率进行了测算和分析。分析结果表明,用随机前沿法测算的知识生产效率较大而且较为稳定;各地区工业的知识生产效率存在较大差异,具有明显的不均衡发展特征;总体而言,我国地区工业的知识生产效率偏低,存在较大的改进潜力。

Based on the panel data of large-and-medium industrial enterprises in 29 provinces and regions of China, the paper estimates and analyses knowledge production efficiencies of regional industries by using the methods of DEA and SFA. The study finds that the efficiencies of knowledge production are higher and more stable while using SFA method. Great differences of knowledge production efficiencies are also found among different provinces. In a word, our knowledge production efficiencies of regional industries are lower, so there exists a big potential to improve them.
