数字普惠金融服务乡村产业振兴效率的测度及时空演进分析

Measurement and spatiotemporal evolution analysis of the efficiency of digital inclusive finance in serving rural industrial revitalization

针对数字普惠金融与乡村产业振兴的关系,选取2011—2021年我国除西藏、香港地区、澳门地区、台湾地区外其余30个省(自治区、直辖市)的面板数据,分别运用DEA-BCC模型和DEA-Malmquist指数方法,基于全国视角与区域视角对我国数字普惠金融服务乡村产业振兴效率进行静态与动态分析,并在此基础上运用核密度估计法对我国数字普惠金融服务乡村产业振兴全要素生产率进行时空演进分析.结果表明,东部、西部、中部、东北部四大区域全要素生产率总体而言呈下降趋势,其主要原因是技术进步较为缓慢;全国数字普惠金融服务乡村产业振兴的全要素生产率下降幅度总体呈收窄趋势,地区间差异不断缩小;东北地区数字普惠金融服务乡村产业振兴全要素生产率的核密度分布存在双峰态势,有明显极化现象,区域内发展水平差异较大.提出了增强数字金融在农业技术进步中的作用,加大对乡村金融人才的培养力度,加强乡村数字普惠金融监管等建议.

In view of the relationship between digital inclusive finance and rural industry revitalization,the panel data of 30 provinces(autonomous regions,municipalities directly under the Central Government)in China except Xizang,Hong Kong region,Macao region and Taiwan region from 2011 to 2021 was selected,respectively the DEA-BCC model and DEA-Malmquist index method were used to conduct a static and dynamic analysis on the efficiency of digital inclusive finance in serving rural industry revitalization in China based on the national perspective and the regional perspective.Based on this,kernel density estimation was applied to analyze the temporal and spatial evolution of the total factor productivity of digital inclusive finance in serving rural industry revitalization.The results indicate that the total factor productivity of the eastern,western,central and northeastern regions is generally declining,mainly due to slow technological progress.Overall,the decline in total factor productivity of digital inclusive finance in serving rural industry revitalization across the country shows an overall narrowing trend,the regional differences are constantly narrowing.The core density distribution of the efficiency of digital inclusive finance in serving rural industrial revitalization in Northeast China shows a bimodal trend and obvious polarization,indicating significant differences in development levels within the region.It was suggested that the role of digital finance in agricultural technological advancement should be strengthened,efforts should be made to enhance the training of rural financial talents,and the regulation of rural digital inclusive finance should be reinforced.
