数字经济发展水平对中国省域出口竞争力的影响研究——基于中国东、中、西部15个省份面板数据的检验

A Study on the Impact of the Development Level of Digital Economy on Provincial Export Competitiveness in China——Based on the Inspection of Panel Data of 15 Provinces in Eastern,Western Central and Western China

近年来,中国数字经济发展势头强劲,成为影响经济和社会发展的关键因素。数字技术不仅深刻改变了国际贸易的信息交互模式,还通过推动跨境电商、市场采购和外贸综合服务等新业态,促进了外贸增长。本文基于2013—2022年中国15个省份的面板数据,借助SPSS的描述性统计、ANOVA分析、皮尔逊相关性分析和回归分析等方法,对15个省份的数字经济发展水平及出口竞争力的波动情况进行研究,了解不同省份数字经济和出口竞争力的发展趋势及成熟度。实证结果表明,数字经济发展水平(熵值法)是影响出口竞争力的重要因素,数字经济对出口竞争力的提升效应存在区域差异。当数字经济发展到一定水平时,对出口竞争力的推动作用具有显著的正向调节作用。本研究结果可为推动中国各省数字经济和出口贸易高质量发展提供参考。

In recent years,China’s digital economy has developed rapidly and become a key factor in eco⁃nomic and social development.Digital technology has not only changed the mode of information interaction in international trade,but also helped to accelerate the growth of foreign trade by promoting new business forms such as cross-border e-commerce,market procurement,and comprehensive foreign trade services.This study collected relevant data from 15 provinces in China from 2013 to 2021 from the statistical yearbooks of different provinces in China,the National Bureau of Statistics,and the PPman database and carried out a study on the development level of the digital economy and the export competitiveness in various provinces through SPSS descriptive statistics,ANOVA analysis,Pearson correlation analysis,and regression analysis,with the purpose to have some understanding on the development trend and maturity of digital economy and ex⁃port competitiveness in different provinces.The Pearson’s correlation coefficient analysis shows that there are regional differences in the improvement effect of the digital economy on export competitiveness,and there may be a threshold effect.When the digital economy develops to a certain level,it has a signifi⁃cant positive effect on promoting export competitiveness.The regression model analysis indicates that the development level of the digital economy(entropy method)is an important factor that affects export competi⁃tiveness.The results of this study can provide a reference for the high-quality development of the digital economy and export trade in Chinese provinces.
