摘要
文章研究了研发投入对全要素生成率的影响。结论表明,近年来工业TFP增长主要源于技术进步的贡献;2002年之后技术效率反而有所恶化;R&D和人力资本都显著地促进了技术进步,但是过分技术"赶超"的思想却同时阻碍了技术效率的提高。增加基础产业的技术投入,能够促进前向R&D溢出,进而提升整个工业行业的技术效率。人力资本更多的起"同化器"的作用,促进R&D投资的效率进而提升TFP;但是文章没有发现人力资本积累作为TFP增长引擎的证据;相反,如果控制人力资本与R&D的交互项,人力资本变量与TFP之间呈显著负相关关系。
This paper investigates the effects of R＆D and human capital on TFP growth.The resuhs as follnwing, firstly, the TFP growth mainly results in technical progress, while technical efficiency even deteriorated since 2002. Secondly, both R＆D investment and human capital accelerate technical progress significantly, but the idea of excessive technology catching-up is bad for the improvement of technical inefficiency. Thirdly, there is a robust positive effect of upstream R＆D spillovers on technical efficienc.y improvement, which means more R＆D input on basic industries improves the whole industries＇ technical efficiency.Human capital severs as ＂assimilator＂ for imprnving efficiency of R＆D and resulting in TFP growth.This paper fail to find evidence of human capital work as ＂TFP growth engine＂, however, a significant negative effect is found for human capital to TFP growth when the interact effects of human capital and R＆D investment are contrnlled.
