数字经济对高技术产业出口竞争力的影响机制研究

Research on the Impact Mechanism of Digital Economy on the Export Competitiveness of High-tech Industries

在数字化转型的时代背景下,数字技术逐渐成为产业发展的重要支撑,研究数字经济对高技术产业出口竞争力提升的作用机制,可以提高高技术产业的发展效率与质量。首先,从理论上分析了数字经济赋能高技术产业出口竞争力提升的作用机制。其次,基于2013年至2021年30个省(区市)的面板数据,通过基准回归模型、面板分位数回归模型、中介效应模型以及空间杜宾模型,检验数字经济对我国高技术产业出口竞争力的影响及其作用路径,并从空间视角验证其区域溢出效应。研究发现:数字经济可以赋能高技术产业出口竞争力提升,该影响可通过产业结构升级、出口技术复杂度提升作为中介效应来实现;随着高技术产业出口竞争力水平的提升,数字经济赋能高技术产业出口竞争力的提升作用逐渐减弱;在空间效应方面,数字经济对本省(区市)及邻近省(区市)的高技术产业出口竞争力均有促进作用。

Under the background of digital transformation,digital technology has gradually become an important support for industrial development,and studying the mechanism of digital economy on the export competitiveness of high-tech industries can improve circular efficiency and quality.This paper first analyzes the mechanism of digital economy to empower the export competitiveness of high-tech industries.Secondly,based on the panel data of 30 provinces from 2013 to 2021,the impact of digital economy on the export competitiveness of China's high-tech industries and its action path are examined through benchmark regression model,panel quantile regression model,mediation effect model and spatial Dubin model,and its regional spillover effect is verified from a spatial perspective.The results show that the digital economy can empower high-tech industries to improve their export competitiveness,and this impact can be achieved through industrial structure upgrading and export technology complexity as mediating effects.With the improvement of the export competitiveness of high-tech industries,the role of the digital economy in enhancing the export competitiveness of high-tech industries has gradually weakened.In terms of spatial effects,the digital economy has promoted the export competitiveness of high-tech industries in this province and neighboring provinces.
