区域创新绩效:金融集聚与贸易开放的空间效应

Regional Innovation Performance:Spatial Effect of Financial Agglomeration and Trade Openness

基于2007-2018年中国省际间面板数据,运用三阶段DEA模型测度区域创新绩效,并构建静、动态空间杜宾模型实证分析金融集聚、贸易开放对区域创新绩效的空间效应、分解效应和异质性效应。研究显示:金融集聚、贸易开放对区域创新绩效有显著促进作用;金融集聚、贸易开放对区域创新绩效具有正向空间相关性;金融集聚水平和贸易开放水平对区域创新绩效产生异质性影响;贸易开放的长短期效应均显著,而金融集聚的短期效应更加显著,对邻省的影响更多体现在短期。

Based on China’s inter-provincial panel data from 2007 to 2018, this paper uses the three-stage DEA model to measure regional innovation performance, constructs the static and dynamic spatial Dubin model to empirically analyze the spatial effect and decomposition effect of financial agglomeration and trade openness on regional innovation performance, and further explore the impact of heterogeneity. Key findings emerge: financial agglomeration and trade openness significantly promote regional innovation performance;financial agglomeration and trade openness have a positively spatial correlation to regional innovation performance;levels of financial agglomeration and trade openness have heterogeneous effects on regional innovation performance;the longterm and short-term effects of trade openness are both significant, while the long-term effects of financial agglomeration are more significant, and the impact on neighboring provinces is more significant in the short-term.
