Abstract
The New Western Land-Sea Corridor development enables East and West to benefit from each other through a network of connected land and sea routes. The research period spans from 2014 through 2022 for all regions situated along the corridor. The study determines provincial and municipal economic connection strength through the urban flow intensity model. The research implements a multi-period difference-in-differences (DID) model to analyze how the corridor affects regional economic development coordination. The research demonstrates three main findings: (1) The corridor's operational start brought significant policy-driven improvements to regional economic connections which fostered unified economic growth. The results demonstrate stability through multiple verification procedures. The corridor's ability to drive coordinated economic development strengthens with time while the "13+1" cooperative framework produces better results. The corridor supports economic balance at different levels between northern and southern areas and between regions with varying economic development stages. The research outcomes provide valuable insights to enhance the New Western Land-Sea Corridor development while stimulating economic growth throughout its entire route.
