本文利用国家统计局工业企业的大样本数据,在微观上估算了我国企业的全要素生产率(TFP),并考察R&D与TFP之间的关系。研究发现:第一,R&D对生产率的提升存在滞后效应,并且滞后效应在民营企业中尤其显著。第二,R&D不但未能提升当期生产率,甚至存在负效应。第三,市场竞争和人力资本通过研发对企业生产率存在显著的边际影响,即:市场竞争越激烈,人力资本水平越高,研发对企业TFP产生的提升效应就越大。并且这种边际效应在国有和民营企业中存在显著差异。本研究有着清晰的政策含义,即在长期持续增进研发的同时,提升竞争与人力资本水平。
本文利用國傢統計跼工業企業的大樣本數據,在微觀上估算瞭我國企業的全要素生產率(TFP),併攷察R&D與TFP之間的關繫。研究髮現:第一,R&D對生產率的提升存在滯後效應,併且滯後效應在民營企業中尤其顯著。第二,R&D不但未能提升噹期生產率,甚至存在負效應。第三,市場競爭和人力資本通過研髮對企業生產率存在顯著的邊際影響,即:市場競爭越激烈,人力資本水平越高,研髮對企業TFP產生的提升效應就越大。併且這種邊際效應在國有和民營企業中存在顯著差異。本研究有著清晰的政策含義,即在長期持續增進研髮的同時,提升競爭與人力資本水平。

Using manufacturing large sample data from National Bureau of Statistics ( 1998--2007 ), we estimate the total factor productivity (TFP) of our enterprise and explore the relationship between the enterprise R&D investment and TFP. We found that: first,enterprise~ R&D spending has significant hysteresis effect,and the hysteresis effect is particularly significant in the private enterprises. Second,the current R&D not only failed to improve the current productivity, even there are negative effects. Third, market competition and human capital plays a significantly marginal role to the enterprise productivity through R&D,i. e. , with the more intense market competition and the higher level of human capital, R&D produces the greater effect to promote TFP. And the marginal effect exist significant differences in the state-owned and private enterprises.
