数字经济如何提升城市出口技术复杂度

How Does the Digital Economy Increase the Urban Export Sophistication in China

在数字经济成为推动贸易高质量发展重要引擎的背景下,研究城市层面出口技术复杂度具有重要意义。本文采用2011—2016年数据测算城市层面数字经济发展水平和出口技术复杂度,并探究数字经济提升城市出口技术复杂度的内在机制。研究发现:数字经济显著提升了我国城市的出口技术复杂度,提高全要素生产率和促进市场竞争是其中两条重要路径;城市数字经济对东部地区、二三线城市以及高技术制成品的出口技术复杂度存在显著的正向影响;在外部需求和技术性贸易壁垒的影响下,数字经济对城市出口技术复杂度仍存在显著的正向影响。

This paper used data from 2011 to 2016 to measure the development level of digital economy and the export sophistication at the city level, and explored the internal mechanism of digital economy to improve the urban export sophistication. The study finds that the development of digital economy can significantly improve the export sophistication of Chinese cities. At the same time, improving total factor productivity and promoting market competition are two important paths for the development of digital economy to improve the urban export sophistication. Further, the development of urban digital economy has a significant positive impact on the export sophistication of eastern cities, second-tier cities,third-tier cities and high-tech manufactured goods. Finally, from the perspective of external demand and technical barriers to trade, it is found that under the influence of external demand and technical barriers to trade, the development of digital economy still has a significant positive impact on the export sophistication of urban.
