我国工业行业技术分解测度与技术溢出渠道分析

Our Industrial Technology Indices Decomposing and Technological Spillover Channels Analysis

首先构建了行业内研发、行业间研发和进出口贸易所带来的技术溢出对技术进步、技术效率及全要素生产率影响的计量模型,然后使用数据包络分析法(DEA)计算了我国工业行业效率指数、技术进步指数和表示全要素生产率的Malquist指数,最后使用我国工业行业数据对计量模型进行了估计。结果表明,国内本行业研发和国内其他行业研发提升本行业技术进步指数的同时降低了行业效率指数,行业内研发对全要素生产率的贡献为正,而行业间研发对全要素生产率的贡献不显著,进口和出口对生产效率的提高无显著作用,对技术进步产生了正向的溢出,进口对全要素生产率的贡献为正,而出口对全要素生产率的贡献不显著。

This paper firstly constructs econometric models reflecting the effects of intra-industry R&D,inter-industry R&D,international technological spillover to technology progress,technology efficiency and total factor productivity(TFP).Secondly,this paper counts our industrial indices of technology efficiency,technology progress and Malquist index by using date enveloped analysis(DE A)method.Finally,this paper estimates the effects of intra-industry R&D,inter-industry R&D,import and export to the stated indices.The results indicate that domestic intra-industry and inter-industry R&D have negative effect to technology efficiency enhancing and have positive effect to technology progress.Intra-industrial R&D effects positive contributions to TFP growth,but inter industrial R&D has no significant effect on TFP.Both import and export have no significant effect on technology efficiency enhancing and have positive one on technology progress.Import has significant positive contributions on TFP growth,but export has no significant contributions on TFP growth.
