摘要
文章基于数字化转型的背景,从邻近性理论出发,以长三角41个城市为研究对象,利用Tobit随机效应面板模型,探讨区域间技术邻近对跨区域协同创新质量的影响和作用机制,同时考虑关系强度的中介作用和数字化水平邻近的调节作用。实证结果表明:技术邻近对跨区域协同创新质量有显著的正向影响,采用工具变量法控制可能的内生性问题后这一结论仍然成立;关系强度在技术邻近与跨区域协同创新质量关系间发挥中介作用;数字化水平邻近正向调节技术邻近与跨区域协同创新质量、技术邻近与关系强度间的关系,还调节了关系强度的中介效应。研究能够丰富邻近性的理论视角,为跨区域协同创新的提质增效提供新思路。
In the context of digital transformation,this study takes 41 cities in the Yangtze River Delta as the research ob⁃jects based on the proximity theory.The Tobit random effects panel model is used to explore the impact of technology proximity on cross-regional collaborative innovation and its mechanism,with the consideration of the mediating role of re⁃lationship strength and the moderating role of digitalization level proximity.The empirical results show that technology proximity has a significant positive effect on the quality of cross-regional collaborative innovation,and the results of IV still support the positive impact in consideration of endogeneity;relationship strength plays a mediating role between tech⁃nology proximity and cross-regional collaborative innovation quality;digitalization level proximity positively moderates the relationship between technology proximity and cross-regional collaborative innovation quality,between technology proximity and relationship strength,and also moderates the mediating effect of relationship strength.This study enriches the theoretical perspective of proximity,and provides new ideas for improving the quality of cross-regional collaborative innovation.
