区域技术市场发展对创新的驱动作用

利用我国2002-2015年省级面板数据,考察技术市场对创新的影响,研究区域研发环境与技术创新的协同作用。首先,通过构建GMM模型稳健性检验,发现在控制物质资本、人力资本、制度因素、R&D投入、FDI、对外贸易、市场化程度等各种影响因素后,技术市场对创新具有显著影响,且对技术含量较高的发明专利的影响弹性最大;其次,通过交互项检验和门槛回归,发现R&D物质资本和人力资本对技术市场存在两个门槛,跨越门槛将增加技术市场的边际创新产出;再次,技术市场发展对各类专利贡献率的测度结果显示,发达地区技术市场对发明专利的贡献最大。据此提出加速我国技术市场发展、因地制宜改善区域研发环境、进一步强化技术市场驱动高质量创新发展等政策建议。

The Impact of Regional Technology Market on Innovation

This paper goes into the impact of technology market on innovation with the provincial panel data of China from 2002 to 2015.We also study the synergy between regional R&D environment and innovation.Firstly, we construct GMM model and conduct detailed robustness test, and find that the technology market has a significant impact on innovation when controlling the factors such as physical capital, human capital, institutional factors, R&D investment, FDI, foreign trade, marketization degree and etc, and has the hugest impact on invention patent.Secondly, through interaction test and threshold regression, we find that R&D material capital and human capital have two thresholds to the technology market.Crossing each threshold will increase the marginal innovation output of the technical market.Thirdly, there is an optimal scope of intellectual property protection, when technology markets’ effect is the greatest.Beyond this range, the elasticity of technology markets’ influence on innovation tends to decrease.Finally, we calculate the contribution rate of technology market.We find that only in developed technology market, the contribution rate of technology markets to invention patent is the greatest.In conclusion, it is necessary to speed up the technology market development in China.Besides, it is a wise choice to improve regional research and development environment according to local conditions.
