数字经济对中国城市制造业出口技术升级的影响——基于产业结构升级和市场化程度的双重视角

The Impact of Digital Economy on the Technological Upgrading of China’s Urban Manufacturing Exports—Based on the Dual Perspective of Industrial Structure Upgrading and Marketization Degree

摘要: 数字经济为我国出口贸易的优质发展提供了重要机遇和新动能。文章利用2011~2021年我国281个地级市面板数据，实证分析数字经济对我国城市制造业出口技术升级的影响和作用机制。研究发现：数字经济对中国城市制造业出口技术升级具有显著的促进作用，从异质性角度来看，这一促进作用在一线城市，长三角珠三角北部湾三大城市群和高技术产业更为明显。从影响机制的角度来说，数字经济可以通过产业结构升级和提升市场化程度，实现出口技术升级。

Abstract: The digital economy provides important opportunities and new momentum for the high-quality development of my country’s export trade. This article uses panel data from 281 prefecture-level cities in my country from 2011 to 2021 to empirically analyze the impact and mechanism of the digital economy on the upgrading of my country’s urban manufacturing export technology. The study found that the digital economy has a significant promoting effect on the technological upgrading of China’s urban manufacturing exports. From the perspective of heterogeneity, this promoting effect is more obvious in first-tier cities, the three urban agglomerations of the Yangtze River Delta, the Pearl River Delta and the Beibu Gulf, and high-tech industries. From the perspective of impact mechanism, the digital economy can achieve export technology upgrades through upgrading the industrial structure and improving marketization.
