摘要
基于2008—2012年上海市科技企业统计中的高新技术企业数据,运用OLS、FE、系统GMM、OP方法分别估算了企业TFP,并研究R&D人力和资本投入与国外技术引进与高新技术企业TFP之间的关系.结果表明:自主研发中的R&D人力投入和国外技术引进对生产率有促进作用,但是自主研发中的R&D资本投入因存在1年时滞而产生抑制作用;当研究自主研发与国外技术引进的吸收作用时,R&D资本的吸收效应可以提高企业TFP,而R&D人力的吸收效应不明显.
Based on the statistical data of high-tech enterprises in Shanghai from 2008 to 2012, it studied the relation- ship among TFP, independent R＆D and technology import. It estimated TFP with four methods of OLS, FE, system GMM and OP, and then made the regression on human and capital inputs of independent R＆D, oversea technology import and TFP of high-tech enterprises. The results show that both human inputs of independent R＆D and technology import have significant positive effects on TFP, while capital input of independent R＆D has negative impact because of the time lag. Considering the absorption effect of R＆D, the absorption of R＆D human input can help to improve TFP, but the absorption of R＆D capital input has no significant influence.
