实现乡村振兴,产业兴旺是关键。现有研究发现,发展数字普惠金融是促进乡村产业兴旺,推动农业农村现代化的重要抓手。本文基于我国2014—2021年1578个县域样本空间面板数据,实证检验数字普惠金融发展是否促进乡村产业兴旺以及它们之间的影响是否存在异质性特征。研究表明：第一,数字普惠金融发展对乡村产业兴旺具有显著正向的促进作用,资本传导效应、技术传导效应和劳动力传导效应是数字普惠金融赋能乡村产业兴旺的作用机理。第二,数字普惠金融发展对乡村产业兴旺的影响存在双重门槛效应和空间异质性。当数字普惠金融发展处于第一门槛值下方（DIF≤0.186）时,对乡村产业兴旺影响呈现“弱显著”当数字普惠金融发展跨过第一门槛值,处于第二门槛值下方（0.186<DIF≤0.867）时,对乡村产业兴旺正向促进作用明显增强;当数字普惠金融发展跨过第二门槛值上方（DIF>0.867）时,对乡村产业兴旺正向促进作用相较第一、第二门槛之间的影响有较大程度的下降,表明空间溢出作用开始通过涓滴效应和扩散效应传导机制辐射周边地区,对本地乡村产业兴旺正向促进作用边际效应递减。

Based on the spatial panel data of 1578 county samples in China from 2014 to 2021, this paper empirically tests whether the development of digital inclusive finance promotes the prosperity of rural industries and spatial heterogeneity. The results show that: firstly, the development of digital inclusive finance plays a significant positive role in promoting the prosperity of rural industries. This is due to the capital transmission effect, technology transmission effect, and labor transmission effect that digital inclusive finance facilitates. Secondly, there are dual threshold effects and spatial heterogeneity in the impact of digital inclusive financial development on the prosperity of rural industries. When the development level of digital inclusive finance is below the first threshold （DIF ≤ 0.186）, its impact on the prosperity of rural industries is “weakly significant”. When the development of digital inclusive finance crosses the first threshold and is below the second threshold （0.186<DIF ≤ 0.867）, the positive promotion effect on the prosperity of rural industries is significantly enhanced. When the development of digital inclusive finance crosses the second threshold （DIF>0.867）, the positive promotion effect on the prosperity of rural industries is significantly reduced compared with the impact between the first and second thresholds. This indicates that the spatial spillover effect begins to radiate the surrounding areas through the trickle-down effect and diffusion effect transmission mechanism, and the positive promotion effect on the prosperity of local rural industries diminishes.
