摘要
基于全国1880个县的截面数据,采用Moran's I指数、泰尔指数、地理加权回归等方法,对县域数字经济发展的空间特征进行研究,并具体分析影响因素的作用程度和方向。研究发现:中国县域数字经济整体呈现“东高西低”的空间分布格局,且数字乡村总指数及各分维度指数均存在显著的空间正相关性。县域数字经济发展差异主要来自于区域内差异,贡献率为66.24%。从影响因素看,经济发展水平和人力资本对县域数字经济的影响较大,但对不同地区的影响效果存在异质性。最后,根据研究结果得出启示并提出建议,为推进县域经济高质量发展提供参考。
Based on the cross-sectional data of 1880 counties in China,this paper adopts Moran's I index,Thiel index and geographically weighted regression to study the spatial characteristics of the digital economy development in counties,and specifically analyzes the effect degree and direction of influencing factors.The results show that the spatial distribution of China's county-level digital economy largely follows an“east high and west low”pattern,and there is a significant positive spatial correlation both in the overall digital rural index and its sub-dimensional indices;the development disparity mainly comes from intra-regional differences,accounting for 66.24%of the variance;in terms of influencing factors,the economic development level and human capital have a significant impact on the digital economy,but their effects vary across different regions.Drawing from these results,it puts forward insights and recommendations to provide a reference for promoting high-quality economic development in county-level regions.
