创新要素流动如何影响区域创新能力——基于空间视角下金融结构调节作用的非线性检验

The Impact of Innovation Factor Flow on Regional Innovation Capability——Non-linear Testing of the Regulatory Role of Financial Structure from a Spatial Perspective

提升区域创新能力是实现创新驱动战略的重要途径。文章基于我国2005—2019年省级面板数据,选用动态空间杜宾模型验证创新要素流动对区域创新能力提升的促进作用,在此基础上进一步讨论金融结构在其中的非线性调节作用。研究发现:以金融规模、金融活力和金融效率作为门槛变量,跨越门槛值后创新要素流动对区域创新能力提升的促进作用得到强化。脉冲响应函数进一步论证了合理稳定的金融结构会在其中产生正向冲击作用。

Based on the provincial panel data of China from 2005 to 2019,this paper selects the dynamic spatial Dobbin model to verify the promoting effect of innovation factor flow on the improvement of regional innovation ability,and further discusses the nonlinear regulation of financial structure on this basis.The study found that:taking financial scale,financial vitality and financial efficiency as threshold variables,the promotion of innovation factor flow on the improvement of regional innovation ability has been strengthened after crossing the threshold.Impulse response function further demonstrates that a reasonable and stable financial structure will have a positive impact.
