数字经济对城乡融合发展的空间溢出及门槛效应研究--以浙江省为例

Research on the Spatial Spillover and Threshold Effect of the Digital Economy on the Urban-Rural Integration-A Case Study of Zhejiang Province

文章基于2007—2020年浙江省11个地级市的数据,构建空间面板模型和门槛回归模型深入探讨了数字经济对城乡融合发展的影响。结果显示:(1)浙江省内部城乡融合发展水平差异明显,整体来看浙江东北地区明显高于浙西南地区,城乡融合水平较高的地区对周边发展水平较低的地区具有明显的辐射带动作用;(2)数字经济对城乡融合发展存在显著的正向空间溢出效应,本地区数字经济发展可以有效带动周边地区城乡融合水平的提升,政府干预程度和经济发展水平的提高同样有利于城乡融合的发展;(3)城乡融合受经济发展水平影响与数字经济呈非线性关系。

This paper constructs a spatial panel model and a threshold regression model based on the data of 11 cities in Zhejiang Province from 2007 to 2020 to deeply explore the complex impact of the digital economy on the development of urban-rural integration.The results show that:(1)There are obvious differences in the development level of urban-rural integration within Zhejiang Province.On the whole,northeastern Zhejiang has a significantly higher level than southwestern Zhejiang.Areas with a higher level of urban-rural integration have an obvious radiating effect on surrounding areas with a lower level of development.(2)The digital economy has a significant positive spatial spillover effect on the development of urban-rural integration.The digital economy in this region can effectively promote the development of urban-rural integration in surrounding areas,and the improvement in the degree of government intervention and economic development is also conducive to the development of urban-rural integration.(3)Urban-rural integration is affected by the economic level and has a nonlinear relationship with the digital economy.
