摘　　要：为探究数字普惠金融驱动农村三产融合的影响,本文利用2011—2020年的省级面板数据,对农村三产融合发展水平进行测算,并运用熵值法和耦合协调度模型,探究数字普惠金融与农村产业融合之间的协同效应。进一步地,利用Dagum基尼系数和核密度估计模型,对数字普惠金融在促进农村三产融合发展过程中的区域异质性及其随时间空间的变化趋势进行实证检验。结果表明,数字普惠金融能够有效推动农村三产的融合与协同发展,且这一融合过程在不同区域表现出显著的差异性,主要体现在两个系统的耦合协调程度上。随着时间的推移,区域间的差异性影响力呈现递减趋势,与此同时,超变密度的影响则日益增强。两者之间存在着明显的空间聚集效应与空间相关性。To investigate the impact of digital inclusive finance on the integration of rural three industries,this paper utilizes provincial panel data from 2011 to 2020 to measure the development level of the integration of rural three industries.By employing the entropy method and the coupling coordination degree model,we explore the synergistic effect between digital inclusive finance and rural industrial integration.Furthermore,using the Dagum Gini coefficient and kernel density estimation model,we conduct an empirical test on the regional heterogeneity of digital inclusive finance in promoting the development of rural three industry integration and its changing trends over time and space.The results show that digital inclusive finance can effectively drive the integration and coordinated development of rural three industries,and this integration process exhibits significant regional differences,mainly reflected in the degree of coupling and coordination between the two systems.Over time,the influence of regional differences shows a decreasing trend,while the impact of super variable density is increasingly strengthening.There is a clear spatial agglomeration effect and spatial correlation between the two.
