摘　　要：创新赋能是国际贸易通道实现高质量发展的重要着力点。以西部陆海新通道为准自然实验,运用多时点DID模型系统考察国际贸易通道如何发挥创新赋能效应。研究发现,西部陆海新通道对城市的创新质量有显著正向作用,其核心机制是空间要素集聚效应、资源错配矫正效应和市场规模扩大效应,且存在时空动态效应;西部陆海新通道对创新要素和创新技术的影响较大,暂未形成创新产业的赋能效应;主通道和重要枢纽的政策效应更为明显,经济基础好、制度环境优的城市更能激发创新潜力;西部陆海新通道存在显著的创新质量外溢效应,最优辐射空间是距通道100千米范围内。Innovation empowerment is an important focus for international trade channels to achieve high-quality development.Taking the New Western Land-Sea Corridor as a quasi-natural experiment,the multi-time point DID model was used to systematically examine how international trade corridors can play an innovation empowerment effect.The study found that the New Western Land-Sea Corridor has a significant positive effect on the innovation quality of cities.Its core mechanism is the agglomeration effect of spatial factors,the correction effect of resource mismatch and the effect of market scale expansion,and there is a spatiotemporal dynamic effect.The New Western Land-Sea Corridor has a greater impact on innovation factors and innovative technologies,and has not yet formed an enabling effect for innovative industries.The policy effects of main channels and important hubs are more obvious,and cities with good economic foundations and excellent institutional environments can better stimulate innovation potential.The New Western Land-Sea Corridor has a significant spillover effect on innovation quality,and the optimal radiation space is within 100 kilometers of the channel.
