New infrastructure is a crucial tool for fostering new quality productive forces and high-quality economic development.In the context of transitioning from traditional productive forces to new quality ones,it is of great significance to scientifically construct an evaluation system for the development level of new infrastructure,measure the actual level in each region,and identify their strengths and weaknesses,in order to foster the emergence of new quality productive forces and enable high-quality economic development. Based on 29 specific indicators in three subsystems,namely information infrastructure,integration infrastructure,and innovation infrastructure,this paper adopts the entropy weight method to calculate the index of China's new infrastructure.Then,it portrays the spatial and temporal distribution characteristics of the new infrastructure and its components,as well as their evolution trends based on the Dagum Gini coefficient,the center of gravity method,and the Markov chain method.The findings reveal that the index of China's new infrastructure exhibits an overall upward trend,gradually forming a double-core structure with the eastern coastal regions and Sichuan as the dense areas.Inter-regional differences are identified as the primary source of overall spatial differences,followed by intra-regional and hyper-variable density differences.The center of gravity mainly shifts towards the southwest,showing path dependence in terms of the development level.However,with the prolongation of the intervals,provincial-level regions with low levels undergo a leapfrog shift after three years of the interval.The findings provide valuable insights into the promotion of the construction of new infrastructure and the development of new quality productive forces. This paper makes the following marginal contributions.First,in terms of indicator construction,it optimizes the new infrastructure indicator system on the basis of the original results,which makes the constructed indicator system able to provide a comprehensive and scientific assessment of the level of new infrastructure in each region.Second,in terms of research content,it enriches the examination of new infrastructure,especially the portrayal of the evolution of differences and the dynamics of its distribution,which helps to accurately understand the characteristics of the spatial differences in the development of new infrastructure in China.Third,in terms of application value,it puts forward policy recommendations based on the results of an all-round and multi-faceted examination of the level of new infrastructure construction in 31 provincial-level regions in China,which holds great significance for promoting the construction of new infrastructure and the coordinated development of regions.
