智慧城市建设能促进城市数实融合吗?--基于“准自然实验”的证据

Can Smart City Building Promote Urban Digital-Reality Integration?—Evidence Based on"Quasi-Natural Experiments"

数实融合是中国构建新发展格局和推动高质量发展的重要途径。文章基于2005-2021年280个地级及以上城市数据,实证检验了智慧城市对城市数实融合的影响及其机理。研究发现:智慧城市建设对城市数实融合程度有显著的促进作用,其机制是通过创新效应、人才集聚效应与对外开放效应而实现;智慧城市对城市数实融合的促进作用因城市的区域位置存在明显差异,在中部地区以及特大城市,智慧城市对城市数实融合程度的促进作用较大,而在东西部地区以及中小规模城市与大规模城市,该促进作用并不显著。该研究为推进数字经济与实体经济深度融合提供城市视角的证据,对于中国式现代化和高质量发展目标的实现具有重要意义。

Digital-reality integration is an important way for China to build a new development pattern and promote high-quality development.Based on the data of 280 prefecture-level and above cities from the year 2005 to 2021,the paper empirically examines the impact of smart cities on urban digital-real integration and its mechanism.The findings are:the construction of smart cities has significantly promoted the degree of urban digital-reality integration,and its mechanism is realized through the innovation effect,talent concentration effect and the opening-up effect;the promotion effect of smart cities on urban digital-reality integration varies significantly with the location of the cities;the promotion effect of smart cities on the degree of urban digital-reality integration is greater in the central region and mega-cities than in the east and west regions,small and medium-sized and large-scale cities,where the facilitating effect is not significant.This study provides evidence from an urban perspective to promote the deep integration of the digital economy and the real economy,which is of great significance for the realization of Chinese-style modernization and the goal of high-quality development.
