在知识经济时代背景下,区域创新在区域经济增长中的作用不言而喻,企业作为区域创新活动的重要主体之一,不同体制企业对区域创新效率溢出效应的影响值得关注。理论上各地区之间的区域创新会彼此影响,产生溢出效应,通过全局空间自相关检验和局域空间自相关检验,我国区域创新效率呈现出显著的区域依赖特征,采用空间计量模型将空间效应纳入实证研究,分析国有企业、民营企业和外资企业对区域创新效率溢出效应的影响,发现国有企业和外资企业均能够显著的、正向的影响区域创新效率溢出,即国有企业和外资企业均能够促进临近区域创新效率的提升,并且国有企业相比外资企业的影响效果更加明显;民营企业在技术创新滞后期1年对区域创新效率溢出没有显著的影响,在滞后期2~3年对区域创新效率溢出呈现出较为显著的负向影响。最后得出:国有企业是技术扩散的中心,从区域创新效率溢出效应角度来说,国有企业是高效的。
Under the background of knowledge-based economy, the role of regional innovation in regional economic growth is self-evident. As one of the important subjects of regional innovation activities, the influence of different institutional enterprises on the spillover effect of regional innovation deserves our attention. In theory, regional innovation among regions will affect each other and produce spillover effect. Through global spatial autocorrelation test and local spatial autocorrelation test, the regional innovation efficiency of our country shows a significant regional dependency. By using spatial measurement model, the spatial effect Empirical studies are conducted to analyze the impact of state-owned enterprises, private-owned enterprises and foreign-funded enterprises on the spillover effect of regional innovation efficiency. It is found that both state-owned enterprises and foreign-funded enterprises can significantly and positively affect the overflow of regional innovation efficiency, that is, both SOEs and FIEs can Promote the efficiency of innovation in the neighboring regions, and the effect of state-owned enterprises is more obvious than that of foreign-funded enterprises; private enterprises have no significant impact on the spillover efficiency of regional innovation in the lag phase of technological innovation, and lag behind in 2 to 3 years of regional innovation The efficiency overflow shows a more significant negative effect. At last, it concludes that state-owned enterprises are the center of technology diffusion. From the angle of spillover effect of regional innovation, state-owned enterprises are efficient.
