东西部对口帮扶政策与企业异地投资

East-West Pairing Assistance and Cross-Regional Investment

对口帮扶作为一种横向转移支付方式,在缓解地区发展不平衡等方面取得了突出成就。文章基于2010—2020年地级市层面异地投资子公司数量的面板数据,以2016年《关于进一步加强东西部扶贫协作工作的指导意见》为政策背景,运用双重差分法探讨了对口帮扶对企业异地投资的政策效应。研究发现,两地建立对口帮扶结对关系显著促进了帮扶地对被帮扶地进行跨区域投资,且不存在地理距离远近和产权性质不同的异质性影响,但受到市场化水平和方言异质性的影响。进一步分析发现,对口帮扶政策在两城市行政等级不同组合下呈现出不同的影响效应。最后,从帮扶双方角度分别探究该政策对异地投资的调节效应。本文研究结论对新时期开展对口帮扶政策的研究创新提供了新的经验证据。

Pairing assistance, as a form of horizontal transfer payment, has achieved outstanding achievements in mitigating regional development imbalances. Using panel data on the number of cross-regional investment subsidiaries of the city of prefecture-level from 2010 to 2020, this paper uses the difference-in-differences method to explore the policy effects of pairing assistance on enterprise cross-regional investment in the context of the 2016 “Guiding Opinions on Further Strengthening East-West Poverty Alleviation Cooperation.” The research findings show that the establishment of a pairing assistance relationship between the two regions significantly promotes cross-regional investment of the assisting region in the assisted region. Moreover, there is no heterogeneity effect of geographical distance or property rights, while there is an impact from marketization and dialect heterogeneity. Further analysis finds that the effects of pairing assistance policy on cross-regional investment vary with the different combinations of administrative levels between the two cities. Finally, the paper explores the regulatory effects of the pairing assistance policy on cross-regional investment from the perspectives of both the assisting and assisted parties. The research findings provide new empirical evidence for the innovative development of pairing assistance policy in the new era.
