The 5G technology pilot has become an important way to enhance the international competitiveness of digital trade.This article selects 292 prefecture-level cities from the CEIC Global Economic Database from 2005 to 2021 as research objects,and uses a multi time point DID model to evaluate the impact and mechanism of 5G technology pilot projects on the international competitiveness of digital trade.The pilot of 5G technology can significantly enhance China's international competitiveness in dig-ital trade.Technological innovation is a mediating variable between 5G technology pilot projects and international competitiveness in digital trade.The rationalization and advancement of industrial structure have a mediating effect on the impact of 5G technolo-gy pilot projects on the international competitiveness of digital trade.The promotion effect of 5G technology pilot policies on China's international competitiveness in digital trade is relatively greater in cities that have opened the China Europe freight train.The indirect effect of 5G technology pilot on the international competitiveness of digital trade is greater than the direct effect.Fi-nancial and tax policies should be formulated to encourage enterprises to achieve industrial upgrading through digital transforma-tion,and continuously enhance the promoting effect of the opening of the China Europe freight train on China's international com-petitiveness in digital trade.
