Abstract 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.
