Research on the Spatiotemporal Differences Analysis and Dynamic Evolution Characteristics of Digital Economy Development in Liaoning Province
摘要
Abstract
Digital economy has become the"new engine"of social development.Its measurement,spatiotemporal differences,and dynamic evolution characteristics are also important issues to be explored.This paper introduces the text analysis method to build the digital economy index system,uses the entropy method to calculate the comprehensive index of digital economy,uses Moran's I,Dagum Gini coefficient,Kernel density estimation,and spatial Markov chain to reveal the space-time difference and dynamic evolution characteristics,and uses space σ convergence to study the characteristics of convergence during 2011-2019.The results find that the level of the digital economy in Liaoning Province during 2011-2019 has improved,but there is a significant imbalance in regional development.The unbalanced development of Shenyang's modern metropolitan area and the Liaoning coastal economic belt is the main factor affecting the difference in the digital economy of Liaoning Province.Cities at a low level of digital economic development are more likely to develop rapidly,and even achieve leapfrog growth.关键词
