数字普惠金融对长三角地区乡村振兴的空间溢出效应研究

The Cross-Regional Radiation of Digital Financial Inclusion: Implications for Countryside Development in the Yangtze River Delta

摘要: 基于2011~2023年长三角地区41个城市面板数据，构建了乡村振兴评价指标体系，利用空间计量模型探讨了数字普惠金融对长三角地区乡村振兴影响的空间溢出效应。结果表明：在长三角地区，数字普惠金融和乡村振兴存在显著的空间集聚现象；数字普惠金融在驱动本地乡村发展的同时，还表现出显著的跨区域辐射能力，对周边城市的乡村振兴形成了正向的空间溢出；数字普惠金融对乡村振兴的影响存在显著的空间异质性，中心城市更多表现为“本地驱动、竞争格局”，而外围城市则呈现“溢出显著、协同发展”的特征；数字普惠金融对长三角地区乡村振兴的促进效应存在双重门槛效应；随着数字普惠金融发展水平的不断提升，其对乡村振兴的边际促进效应呈现出“先降后升”的“U”型特征。因此，建议通过强化区域协同、夯实数字基建、深化产业融合等措施，增强数字普惠金融对乡村产业振兴的支撑作用。

Abstract: Drawing on panel data from 41 cities in the Yangtze River Delta (2011~2023), this paper establishes an indicator system to assess rural revitalization. Through spatial econometric analysis, we investigate the spatial interdependence of digital financial inclusion on rural development. Results demonstrate a marked tendency for spatial clustering in the region. Crucially, digital inclusive finance acts as a dual engine: it propels local development while simultaneously fostering positive externalities in adjacent areas through spatial diffusion. To leverage this mechanism, we recommend enhancing regional coordination, reinforcing digital infrastructure, and promoting deeper industry-finance integration to bolster the rural economy. The impact of digital inclusive finance on rural revitalization exhibits significant spatial heterogeneity, with central cities predominantly demonstrating a “locally-driven, competitive pattern”, while peripheral cities display “significant spillover and collaborative development” characteristics. In the Yangtze River Delta region, the promoting effect of digital inclusive finance on rural revitalization shows a dual-threshold effect. As the development level of digital inclusive finance continues to rise, its marginal promotion effect on rural revitalization presents a “decrease-then-increase” U-shaped characteristic.
