摘要
本文对我国科技活动的直接人力资本投入、R&D投入与创新绩效间之间的定量关系进行了实证分析。在理论分析的基础上,运用主成分分析法对我国各类科技活动的直接人力资本投入、R&D投入和创新绩效的水平进行了综合评价,并运用Pearson、Kendall和Spearman三种相关分析测算了直接人力资本投入、R&D投入与创新绩效的相关系数,运用Enter回归分析方法测度了直接人力资本投入、R&D投入对创新绩效的贡献度。得出结论:直接人力资本投入、R&D投入与创新绩效正相关,二者对创新绩效的贡献都为正;直接人力资本投入与创新绩效的相关系数略低于R&D投入与创新绩效的相关系数,R&D投入对创新绩效的影响大于直接人力资本投入对创新绩效的影响;对于不同主体的科技活动,直接人力资本投入、R&D投入与创新绩效的相关系数以及前两者对后者的贡献度存在差异。
This paper tries to study the relationships among direct human capital input,R＆D input and innovation performance quantitatively through an empirical analysis on science ＆ technology activities. It evaluates direct human capital input,R＆D input and innovation performance synthetically using the principal component analysis method on the basis of theoretical analysis, and calculates the correlation coefficients among direct human capital input,R＆D input and innovation performance using Pearson, Kendall and Spearman correlation analysis methods. It also measures the contributions to innovation performance of direct human capital input and R＆D input using the enter regression analysis method. And it draws the conclusions as following：firstly,direct human capital input and R＆D input are positively correlated with innovation per- formance and their contributions to innovation performance are positive;secondly,the correlation between direct human capital inputand innovation performance is lower than that between R＆D input and innovation performance, and the contribution of R＆D input to innovation performance is bigger than that of direct human capital input finally, the correlation and the contribution level vary significantly in different S＆T activities.
