创新资本效率及空间溢出效应研究

Research on Innovation Capital Efficiency and Spatial Spillover Effect

利用空间计量模型对风险投资、R&D投资、高技术投资对技术创新的影响效果进行实证建模,研究结果表明,中国R&D投资对技术创新的贡献远远大于风险投资的作用,高技术产业投资对于技术创新正向作用显著,风险投资对技术进步具有阻碍作用,技术创新具有正向的空间溢出效应。这与R&D投入对产学研协同创新绩效的促进作用和知识溢出效应、风险投资的竞争性信息泄露以及中国处于经济体制转型时期的制度环境和产业政策有关。此外,空间自相关、空间自回归和空间杜宾模型的对比研究显示空间自回归模型效果最优。本文为政府和相关部门如何提高技术创新效率提供了理论参考和经验借鉴。

This paper uses spatial econometric model to model the impact mechanism of venture capital,R&D investment and high-tech investment on technological innovation.The results show that the contribution of R&D investment and high-tech industry investment to technological innovation is far greater than that of venture capital.R&D investment has the most significant effect on technological innovation efficiency,and technological innovation has a positive spatial spillover effect.This is related to China’s institutional environment and industrial policy.In addition,in the comparative study of spatial autocorrelation,spatial autoregression and spatial Durbin model,it is found that the spatial autoregression model has the best effect.The conclusion of this paper provides theoretical reference and experience reference for the government and relevant departments to improve the efficiency of technological innovation in China.
