摘要
运用永续盘存法的非传统途径,审慎测算出2003-2021年中国新型基础设施的全套资本存量,进一步分析其区域差异和分布动态演进。研究发现,新型基础设施资本存量以年均14.56%的增长率快速攀升,到2021年高达8.12万亿元。其中,创新基础设施的资本存量处于首位,信息基础设施居次,融合基础设施最小。新型基础设施资本存量的总体差异、在中西部地区的内部差异,以及在东~中部、中~西部地区之间的差异均呈波动下降趋势,如此差异产生的最主要来源是区域间差异。就分布动态演进而言,新型基础设施资本存量具有较为明显的极化特征,存在逐渐增强的正向空间聚集现象,全国整体以及三大区域都存在绝对β收敛趋势,其收敛速度先增加、后减小。同时,信息、创新基础设施资本存量具有绝对β收敛特征,而融合基础设施具有发散特征。
Using the non-traditional approach of the perpetual inventory method,this paper prudently measures the full set of capital stock of China's new infrastructures from 2003-2021,and further analyzes its regional dfferences and distribution dynamic evolution.It is found that the capital stock of new infrastructure climbs rapidly at an average annual growth rate of 14.56%,reaching as high as 8.12 trillion yuan by 2021.Among them,the capital stock of innovation infrastructure is in the first place,followed by information infrastructure,and convergence infrastructure is the smallest.The overall difference,the differences within the central and western regions,and the differences between the eastcentral and central-western regions in the capital stock of new infrastructure all show a fluctuating downward trend,and the most important source of such a difference is the inter-regional difference.As far as the distribution dynamic evolution is concerned,the capital stock of new infrastructure has more obvious polarization characteristics,with gradually increasing positive spatial aggregation phenomenon,and there is a trend of absoluteβ-convergence in the whole country as well as in the three major regions,with the rate of convergence increasing firstly and then decreasing.At the same time,the capital stock of information and innovation infrastructure is characterized by absoluteβ-convergence,while convergence infrastructure is characterized by divergence.
