Measurement of coupling development level of new infrastructure investment and digital transformation and its temporal and spatial evolution trend
Abstract
Based on the coupling mechanism between new infrastructure investment level and digital transformation level, a comprehensive index system is constructed. By using entropy weight method, coupling coordination evaluation model, exploratory spatial data analysis (ESDA) and standard deviation ellipse model, the coupling coordination development level of new infrastructure investment level and digital transformation level in 31 provinces and cities in China from 2014 to 2021 is calculated, and its spatial agglomeration level and spatial-temporal evolution characteristics are analyzed.
