摘　　要：高水平开放是实现高质量发展的必由之路。以长江经济带地级城市为研究对象,基于2010年以来的国际货运代理企业数据,借助城市网络等方法,研究长江经济带双向联动开放发展的演化特征、影响因素。研究发现:长江经济带双向联动开放格局在加速形成,但西向开放还需要加强,上中下游的总体开放程度差异明显;长江经济带对全国其他地区的开放牵引作用不断强化,下游地区总体双向开放联系强度始终最高,上游地区内外双向开放联系增速最快;长江经济带内部下游与上游地区的总体开放联系最高,沪苏浙东向开放门户地位突出,中游与上游地区的开放联系始终最弱,副省级以上及省会城市在经济带双向联动开放发展中作用突出。地方经济发展需求、创新和商务服务能力提升、高能级平台建设、综合交通条件改善等是促进长江经济带双向联动开放的主要影响因素。High level opening up is the way to achieve high quality economic development.Taking the prefecture-level cities in the Yangtze River Economic Belt as the research object,this paper studies the evolution characteristics and influencing factors of the two-way linked opening pattern of the Yangtze River Economic Belt based on the data of international freight forwarding enterprises since 2010,using the methods of urban networks.The study finds that the two-way opening pattern of the Yangtze River Economic Belt is being accelerated,yet westward opening still needs to be strengthened,and the overall openness of the upper,middle and lower reaches differs significantly.The Yangtze River Economic Belt's role in opening up as a traction to other regions of the country has been strengthening.The overall two-way opening linkage intensity in the downstream region is consistently at the highest level,while the upstream region shows the fastest growth in both internal and external two-way opening linkage.The overall opening linkage between the downstream and upstream areas within the Yangtze River Economic Belt is the highest,with Shanghai,Jiangsu,and Zhejiang being highlighted as eastward opening gateways.The opening linkage between the midstream and upstream regions is always the weakest,and cities above the sub-provincial level and provincial capitals take a leading role in the two-way opening development of the economic belt.The demand for local economic development,the improvement of innovation and business service capacity,the establishment of high-level platforms,and the enhancement of comprehensive transportation conditions are the main influencing factors to promote the two-way linked opening of the Yangtze River Economic Belt.
