新基建投资对城市吸引力的影响研究

Research on the Impact of New Infrastructure Investment on Urban Attraction

新型基础设施作为现代化基础设施体系中的关键部分,也是推动社会高质量发展的关键支撑,正逐渐成为我国促投资、稳增长的重要着力点。文章基于2016-2021年全国37个城市新基建投资数据,构建面板固定效应回归模型,实证检验新基建投资对于城市吸引力发展的促进作用,研究发现:新基建投资对城市吸引力增长有显著的促进作用,新基建投资对于不同类型城市的吸引力发展存在异质性,对于一线、新一线、二线城市,新基建投资的促进作用显著,反之规模较小的三线城市促进作用并不明显。

As a key part of the modern infrastructure system and a key support for promoting high-quality social development,new infrastructure is gradually becoming an important focus for promoting investment and stabilizing growth in China.The article is based on new infrastructure investment data from 37 cities in China from 2016 to 2021,and constructs a panel fixed effects regression model to empirically test the promoting effect of new infrastructure investment on urban attractiveness development.The study found that new infrastructure investment has a significant promoting effect on urban attractiveness growth,and there is heterogeneity in the attractiveness development of different types of cities.For first tier,new first tier,and second tier cities,the promoting effect of new infrastructure investment is significant,while for smaller third tier cities,the promoting effect is not significant.
