| 摘 要： | 该文运用1993-2002年中国大中型工业企业的行业面板数据对R&D产出弹性进行了测算.在扩展的柯布道格拉斯生产函数基础上,在估算各工业R&D资本存量、校正R&D双重计算问题后,通过混合OLS、固定效应法和一阶差分法等不同的估计方法进行估计,该文发现中国大中型工业企业的R&D产出弹性约为0.1-0.3.研究还发现,R&D产出弹性还取决于技术机会、企业规模、产权结构等特定的约束条件;技术水平较高、企业规模较大、国有产权比重较低的产业中,R&D产出弹性较大;而在国有产权比重较高的产业中,R&D对生产率没有促进作用.

| Abstract: | THE PAPER ESTIMATES THE ELASTICITY OF OUTPUT WITH RESPECT TO R&D BY USING THE PANEL DATA ON CHINESE INDUSTRIES DURING 1993-2002.BASED ON THE EXPANDED C-D PRODUCTION FUNCTION,CALCULATING R&D CAPITAL STOCK AND REVISING R&D DOUBLE COUNTING PROBLEM,WE FIND THAT R&D OUTPUT ELASTICITY IS APPROXIMATELY 0.1-0.3 THROUGH DIFFERENT REGRESS MODELS INCLUDING POOLED OLS,FIXED EFFECTS AND FIRST DIFFERENCE.WE ALSO FIND THAT THE CONTRIBUTION OF R&D TO PRODUCTIVITY ALSO DEPENDS ON SOME CONSTRAINTS SUCH AS TECHNICAL OPPORTUNI... |
