摘　　要：利用最新的动态OLS面板协整向量估计法,研究了大中型工业企业中全部企业、国有企业和三资企业的产出对研发资本的弹性,发现在规模报酬可变假设下,研发的作用不显著,而在规模报酬不变假设下,国有企业研发效率低于全部企业的平均研发效率,但三资企业的研发作用并不显著。该结论非常稳健,对研发资本折旧率不敏感。Using the latest dynamic OLS estimator for panel cointegration vectors, this paper reconsiders estimation of elasticity to R＆D for three type of samples： all, state-owned and foreign- invested industrial enterprises with large and medium size, and finds new conclusions： I. R＆D capital has no significant effects on output without the assumption of constant return to scale; 2. Under the assumption of constant re- turn to scale, the R＆D efficiency of state - owned firms is below average R＆D efficiency and R＆D capital of foreign- invested finms has also no significant role. Conclusions are robust to the depreciation rate of R＆D.
