新城建试点对城市基础设施韧性的影响OACHSSCD

The construction of new urban infrastructure is of great significance for enhancing the resilience of urban infrastructure and strengthening the sense of security and happiness of the people.Based on the panel data of 258 prefecture-level cities in China from 2012 to 2023,this paper used the difference-in-differences model to explore the impact and mechanism of the pilot project of new urban infrastructure construction on the resilience of urban infrastructure.The research found that:(1)The Pilot projects for the construction of new urban infrastructure could significantly enhance the resilience of urban infrastructure.(2)Mechanism analysis indicated that technological innovation and economic input are important ways to enhance the resilience of urban infrastructure.(3)Heterogeneity analysis indicated that the pilot policy for the construction of new urban infrastructure had a significant effect in the eastern and central regions,while the significant effect in the western region was lower than that in the eastern and central regions.Meanwhile,the higher the level of economic development of a city,the more significant the effect of its policies.On this basis,countermeasures and suggestions for strengthening the construction of new urban infrastructure and enhancing the resilience of urban infrastructure are put forward.
