摘　　要：基于中国285个地级市2003—2019年的平衡面板数据,采用多期双重差分模型探析贸易新通道对沿线城市经济联系的影响。研究发现:中欧班列开通显著提高了沿线城市的经济联系,且对不同城市经济联系的影响存在异质性,其对大中型城市与货源地城市的促进效应更强,对小型、特大、超大型城市和铁路枢纽城市、港口城市并无显著促进作用。时间节约效应与资源再配置效应是中欧班列增进城市经济联系的重要机制。中欧班列开通数量、开通时间与城市经济联系增进呈正相关关系,且开通城市显现出一定的虹吸效应。基于结论提出通过加强经济联系助力中欧班列高质量发展的对策建议。Taking the opening of China-Europe Railway Express(CRE)as a quasi-natural experiment,this paper explores the impact of new trade corridor on economic ties of cities along the route based on the balanced panel data of 285 prefecture-level cities in China from 2003 to 2019 using time-varying DID model.It is found that the opening of CRE significantly improves the economic ties of cities;and there is heterogeneity in the impact on the economic ties of different cities,among which,the promotion effect of medium and large-scale cities and source cities is stronger,and it does not have a significant effect on the promotion of small and super-large and mega cities,railroad hub cities and port cities;The time-saving effect and resource reallocation effect are important mechanisms to enhance the city's economic ties.The number and time of CRE are positively correlated with the city's economic ties,and the opening city shows a certain siphon effect.Based on the above conclusions,suggestions are put forward to assist the high-quality development of cities along the route and CRE by strengthening economic ties.
