选取2010—2023年我国30个省级面板数据，实证检验数字贸易与战略性新兴产业绿色技术创新效率的内在关系。结果表明，数字贸易可显著驱动战略性新兴产业绿色技术创新效率提升。中介效应检验结果发现，数字贸易可助推产业结构升级，驱动战略性新兴产业绿色技术创新效率提升。门槛效应检验结果显示，数字贸易对战略性新兴产业绿色技术创新效率提升具有双重门槛效应。异质性分析发现，数字贸易对东部地区和高环境规制强度地区战略性新兴产业绿色技术创新效率的驱动效应更明显。上述研究结果为更好地推进数字贸易发展和提高战略性新兴产业绿色技术创新效率提供有益借鉴。

The article uses panel data from 30 provinces in China from 2010 to 2023 as a research sample to examine the impact of digital trade on the efficiency of green technology innovation in strategic emerging industries. Research has found that digital trade can effectively promote the efficiency improvement of green technology innovation in strategic emerging industries. The results of the mediation effect test found that industrial structure upgrading plays an important mechanism role between the two. The threshold effect results show that there is a double threshold effect on the impact of digital trade on the efficiency of green technology innovation in strategic emerging industries. The heterogeneity analysis results indicate that digital trade has a more pronounced driving effect on the eastern region and areas with high environmental regulation. The above research results provide useful reference for better promoting the sustainable development of digital trade and improving the innovation capability of green technology.
