专利申请量与R&D投入因素的弹性关系研究——基于36个产业面板数据的实证分析

Research on the Elasticity Relationship between Patent Application and R&D Input Factors: The Empirical Study on the Panel Data of Thirty-six Industries

对比分析我国不同类型产业的专利产出对R&D投入要素的敏感程度,采用产业专利申请量变化率与R&D人员全时当量变化率、R&D经费总量变化率、R&D项目总量变化率的比值作为弹性的计算方法,按产业年均专利申请规模划分产业类型并进行对比研究。结果表明:低规模和高规模专利产出的产业中专利申请量受R&D人员全时当量的影响最为明显;中规模专利产出的产业中专利申请量受R&D经费总量的影响最为明显。因此,在制定相关产业政策时需要考虑产业的不同类型,以便建立最有效的R&D投入组合。

In this paper, we focus on the elasticity relationship between R＆D personnel, R＆D investment and R＆D project. Thirty-six industries are separated according to the industry average annual patent application scale. The result shows that in low and high patent scale industries, patent application obviously affected by R＆D personnel per year. In middle patent scale industries, patent application obviously affected by R＆D investment. There- fore, in order to establish the most effective R＆D input combination, we should take the type of patent scale indi- cator into account.
