摘　　要：基于2012—2022年中国258个地级市的面板数据,通过熵值法重新构建数字贸易指标体系,并从技术创新、产业结构升级和金融发展视角构建中介模型,探究数字贸易对出口技术复杂度的影响机制。进一步研究表明,数字贸易对出口技术复杂度的影响存在门槛效应。研究结论为揭示数字贸易影响出口技术复杂度的内在机制提供了思路。The research is based on panel data from 258 prefecture level cities in China from 2012 to 2022.Using the direct value method,a digital trade indicator system is reconstructed,and an intermediary model is constructed from the perspectives of technological innovation,industrial structure upgrading,and financial development to explore the impact mechanism of digital trade on export technology complexity.Further research indicates that there is a threshold effect on the impact of digital trade on the complexity of export technology.The research conclusion provides insights into the underlying mechanisms by which digi-tal trade affects the complexity of export technology.
