基于全球视角的中国数字经济研究

Research on China’s Digital Economy Based on Global Perspective

摘要: 数字经济作为新兴的经济形态，已经成为世界经济增长的重要驱动力。本文分析了全球29个国家数字经济发展的现状和特点。构建8个指标，首先运用纵横向拉开档次法解析各国数字经济发展指数，随后运用σ收敛、β收敛和耦合协调度模型，探究全球数字经济的空间趋势与发展水平。最后的结果显示：全球数字经济化水平呈现出稳步上升的趋势，且差距在逐步缩小，国家间数字经济发展呈现出空间聚集性特征，发达国家与发展中国家经济协调程度相差较大。从各大洲角度看，国家间的数字经济化发展差距在增大，但依然保持上升趋势。

Abstract: As an emerging economic form, digital economy has become an important driving force for world economic growth. This paper analyzes the current situation and characteristics of digital economy development in 29 countries around the world. Eight indicators are constructed. First, the horizontal and vertical separation grade method is used to analyze the digital economy development index of various countries. Then, the spatial trend and development level of the global digital economy are explored by using σ convergence, β convergence and coupling coordination degree models. The final results show that the level of global digital economy shows a trend of steady rise, and the gap is gradually narrowing, the development of digital economy among countries shows the characteristics of spatial clustering, and the degree of economic coordination between developed countries and developing countries is greatly different. From the perspective of each continent, the gap between countries in the development of digital economy is increasing, but it still maintains an upward trend.
