Abstract:

With the development of 5th Generation Mobile Communication Technology(5G), industrial internet, artificial intelligence, smart manufacturing, smart construction, and other new technologies or new industries, a new infrastructure has emerged. The scale and the spatial distribution structure of new infrastructure across various regions of China from 2020 to 2022 were measured based on the official annual engineering construction project plans, and the impacts of the digital economy were analyzed by using the spatial Durbin model. The results indicate that the new infrastructure projects are mainly distributed in Eastern, Central, and Southern China. Meanwhile, the Moran’s I index demonstrates a statistically significant positive spatial autocorrelation, indicating that there is a significant trend of spatial agglomeration among these new infrastructure projects. The digital economy is significantly affecting the spatial distribution of the new infrastructure. The impact of the digital economy on the new infrastructure can cross regions and has significant spatial spillover effects, which reflects the virtual characteristic of the new infrastructure and digital economy. Therefore, various regions should coordinate the digital economic development needs of local and surrounding regions to rationally plan new infrastructure projects, ensuring the supporting capacity of infrastructure while preventing over-investment.

随着5G、工业互联网、人工智能以及智能制造、智能建造等新技术、新产业的深化发展,新基建应运而生。基于各地区建设项目计划,对2020—2022年我国各地区的新基建规模进行统计,在此基础上分析新基建的空间分布结构,并利用空间杜宾模型探索其所受数字经济的影响效应。结果发现,我国新基建主要分布在华东、华中、华南等区域,莫兰指数显示其存在显著的空间正自相关性,空间集聚性明显。不同地区新基建的分布受到数字经济的显著影响,且数字经济不仅影响本地的新基建规模,其需求引导性也具有空间溢出效应,影响着异地的新基建规模,从而体现了新基建和数字经济的虚拟特征。因此,各地应统筹本地和异地的数字经济发展需求以合理规划新基建项目,确保基础设施支撑力的同时避免过度投资。
