摘　　要：聚焦于西部陆海新通道,运用T检验、动态面板数据模型、双重差分法、多时点双重差分法及事件分析法,系统分析该通道设立对沿线地区新质生产力提升的直接影响及内在机制。研究发现:西部陆海新通道的设立显著促进了沿线地区新质生产力的提升,且这一正面效应随时间推移逐步增强,突显出通道建设对区域经济发展的长期贡献。中介效应分析进一步发现,贸易的中介效应显著且正向,表明通道通过促进区域内外贸易的流通与繁荣,有效推动了沿线地区新质生产力的提升;外商直接投资的中介效应相对较弱,表明沿线区域在吸引高质量外资方面仍面临挑战;值得注意的是,虽然通道设立后基础设施得到了一定程度的改善和提升,但其作为中介对沿线地区新质生产力的间接提升效应并不显著,这提醒我们需要定制更为细致的政策规划和长期发展战略,以确保基础设施建设能够切实支撑区域新质生产力的持续增长。This study focuses on the Western Land-Sea New Corridor and uses T-tests,dynamic panel data models and multi-period difference-in-differences approaches to systematically analyze the direct effects of the corridor on the new-quality productive forces in the regions along the corridor,as well as its intrinsic mechanisms.The study shows that the establishment of the Western Land-Sea New Corridor significantly promotes the enhancement of new-quality productive forces in the regions along the corridor,and this positive effect gradually strengthens over time,highlighting the long-term contribution of the corridor’s construction to regional economic development.Mediator effect analysis further reveals that the mediating effect of trade is significant and positive,indicating that the corridor effectively promotes the enhancement of new-quality productive forces in the regions along the corridor by facilitating and prospering trade both within and outside the region.The mediating effect of foreign direct investment is relatively weak,suggesting that regions along the corridor still face challenges in attracting high-quality foreign capital.It is noteworthy that although the establishment of the corridor has led to a certain degree of improvement and enhancement in infrastructure,its indirect enhancing effect on the new-quality productive forces in the regions along the route through its intermediary role is not significant.It serves as a reminder that we need to develop more nuanced policy planning and long-term development strategies to ensure that infrastructure development can effectively support the sustained growth of regional new-quality productive forces.
