摘要
从人口城镇化、经济城镇化、社会城镇化、生态城镇化四维度解构新型城镇化,在构建数字经济助推新型城镇化发展理论框架的基础上,以2011-2020年中国283个地级及以上城市的面板数据为样本,利用空间杜宾模型和面板门槛模型实证检验了数字经济对新型城镇化的“本地-邻地”效应和门槛效应。结果表明:①数字经济对本地及邻地新型城镇化均具有显著推动作用;②数字经济对本地新型城镇化4个子维度影响显著,并对邻地人口城镇化、经济城镇化表现出明显空间溢出效应;③东、中西部区域差异导致数字经济对新型城镇化产生不同影响效果;城市规模过大或过小均不利于数字经济有效助力本地及邻地新型城镇化发展;④数字经济对新型城镇化的推动作用具有非线性特征,当数字经济水平越过第二门槛值后,其推动作用大为增强,数字经济对人口城镇化和经济城镇化存在双重门槛,对生态城镇化存在单一门槛。
This paper deconstructed new urbanization from the four dimensions of population urbanization,economic urbanization,social urbanization,and ecological urbanization.Based on the theoretical framework of the digital economy promoting the development of new urbanization,using panel data from 283 prefecture-level and above cities in China from 2011 to 2020 as samples,this paper empirically tested the“local-neighborhood”effect and threshold effect of the digital economy on new urbanization using spatial Durbin model and panel threshold model.The results showed that:①Digital economy had a significant promoting effect on both local and neighboring new urbanization.②Decomposing the action path,it was found that the digital economy had a significant impact on the four dimensions of local new urbanization,and exhibited obvious spatial spillover effects on neighboring population urbanization and economic urbanization.③Heterogeneity analysis revealed that regional differences between the eastern and central-western regions have led to different effects of the digital economy on its new urbanization;A city that was too large or too small was not conducive to the digital economy to effectively promote the development of new urbanization in the local and neighboring areas.④The promotion effect of the digital economy on new urbanization had nonlinear characteristics.When the level of the digital economy exceeded the second threshold value,its promotion effect was greatly enhanced.Further analysis showed that there were dual thresholds for population urbanization and economic urbanization,and a single threshold for ecological urbanization.
