基于空间杜宾模型的数字乡村建设水平测度及影响因素探究

Measurement of Digital Rural Construction Level and Its Influencing Factors Based on Spatial Durbin Model

基于中国30个省(区、市)2016—2022年的面板数据,从数字基础设施建设、乡村数字产业、乡村数字生活、乡村数字治理4个维度构建了数字乡村建设水平评价指标体系,采用熵权TOPSIS法进行测度,进一步根据空间杜宾模型探究了数字乡村建设的影响因素和空间溢出效应。结果表明:(1)中国数字乡村建设水平在增幅、年均增速等指标上均呈现出东部最高、中部次之、西部再次之、东北部最低的态势,具有明显的“马太效应”和空间依赖性。(2)分地区来看,浙江省的数字乡村建设水平最高,观察期内山西省的数字乡村发展最快。(3)人口年龄结构和城镇化水平与数字乡村建设水平呈显著负相关,研发强度和农民收入水平为显著正相关。(4)地区发展水平具有正向空间溢出效应,研发强度和城镇化水平则具有负向空间溢出效应。

Based on the panel data of 30 provinces(municipalities/districts)in China from 2016 to 2022,the evaluation index system of digital rural construction level was constructed from four dimensions:digital infrastructure construction,rural digital industry,rural digital life and rural digital governance,and the entropy weight TOPSIS method was used to measure it.The influencing factors and spatial spillover effect of the digital rural construction were further explored according to the spatial Durbin model.The results show that:(1)In terms of the growth rate and average annual growth rate,the level of digital rural construction in China is the highest in the east,the second in the middle,the second in the west,and the lowest in the northeast,which has obvious“Matthew effect”and spatial dependence.(2)In terms of regions,Zhejiang Province has the highest level of digital village construction,and Shanxi Province has the fastest development of digital rural construction during the observation period.(3)Population age structure and urbanization level are negatively correlated with the level of digital rural construction,while R&D intensity and farmers’income level are positively correlated with the level of digital rural construction.(4)Regional development level has a positive spatial spillover effect,while R&D intensity and urbanization level have a negative spatial spillover effect.
