摘要
数字经济正成为全球经济与贸易增长的重要力量,利用2002—2023年货物进出口总额与数字经济相关变量的时间序列数据,在ADF检验的基础上,建立向量自回归(VAR)模型,通过格兰杰因果检验分析法综合探讨货物进出口贸易和数字经济发展水平的关系。结果表明:货物进出口贸易与数字经济发展水平呈现正相关的关系,为后续制定货物进出口贸易政策和货物进出口贸易发展提供依据。
The digital economy is emerging as a crucial force in global economic and trade growth.This paper utilizes the time-series data of the total value of goods import and export and digital-economy-related variables from 2002 to 2023.Based on the ADF test,a Vector Autoregression(VAR)model is established,and the Granger causality test analysis method is employed to comprehensively explore the relationship between goods import and export trade and the development level of the digital economy.The results indicate a positive correlation between goods import and export trade and the development level of the digital economy,providing a basis for formulating subsequent goods import and export trade policies and promoting the development of goods import and export trade.
