虚拟集聚对区域经济协调发展的空间溢出效应研究
Research on the Spatial Spillover Effect of Virtual Agglomeration on the Coordinated Development of Regional Economy

本文基于2012~2022年我国30个省域面板数据，在构建虚拟集聚评价指标体系的基础上，运用空间杜宾模型量化分析了虚拟集聚对区域经济协调发展的空间溢出效应。研究发现：(1) 我国区域经济协调发展水平总体呈现“东高西低、阶梯递减”的不均衡空间分布格局；(2) 虚拟集聚对区域经济协调发展具有显著的“本地效应”和“邻地间接效应”，该结论经过一系列稳健性检验依然成立；(3) 虚拟集聚对周边地区的辐射带动效应比对本地经济的直接推动作用更为突出。研究不仅丰富了虚拟集聚与区域经济协调发展相关领域的理论体系，还为我国形成区域间优势互补、资源共享、互利共赢的新发展格局，提供了坚实的理论依据与战略支持。
Utilizing panel data from 30 provinces in China spanning 2012 to 2022, and based on the construction of an evaluation index system for virtual agglomeration, this study employs the spatial Durbin model to quantitatively analyze the spatial spillover effect of virtual agglomeration on the coordinated development of regional economies. The findings indicate: (1) The level of coordinated regional economic development in China exhibits a generally imbalanced spatial distribution characterized by higher levels in the eastern regions and lower levels in the western regions; (2) Virtual agglomeration exerts a significant “local effect” and “neighborhood indirect effect” on the coordinated development of regional economies, a conclusion that remains robust across a series of robustness tests; (3) The radiating driving effect of virtual agglomeration on neighboring areas surpasses its direct promotion of local economic growth. This research not only enhances the theoretical framework concerning the coordinated development of virtual agglomeration and regional economies but also offers a solid theoretical foundation and strategic guidance for fostering a new development paradigm of complementary strengths, resource sharing, mutual benefits, and win-win outcomes among regions in China.
