“双循环”背景下长江经济带节点城市的功能评价与空间组织方向

Function Evaluation and Spatial Organization Direction of Node Cities in the Yangtze River Economic Belt under the Background of“Double Cycle”

“双循环”背景下,长江经济带节点城市要更加注重流通运输与对外开放功能的有效发挥,并以新功能要求明确其在新发展格局中的定位,从而放大长江经济带的支点效应。长江经济带节点城市仍存在功能发挥动力不足、功能主体行政指向明显、功能分布空间差异突出等现实问题。从城市、城市群以及城市空间网络三大空间组织联系结构出发,打造成为国际资源吸纳承转中心、超级增长点和网络联动中心是节点城市的组织方向。提升自主创新能力、增添区域合作交流路径、构建数字化信息共享平台是推动长江经济带节点城市发展的重要推力。

Under the background of“double circulation”,node cities in the Yangtze River Economic Belt should pay more attention to the effective play of circulation,transportation and opening to the outside world,and define their positioning in the new development pattern with new functional requirements,so as to amplify the fulcrum effect of the Yangtze River Economic Belt.The node cities of the Yangtze River Economic Belt still have some practical problems,such as insufficient impetus for functional development,obvious administrative direction of functional subjects,and prominent spatial differences in functional distribution.Starting from the three spatial organization and connection structures of cities,urban agglomerations and urban spatial networks,it is the organizational direction of node cities to build themselves into international resource absorption and transfer centers,super growth points and network linkage centers.Improving independent innovation capacity,adding routes for regional cooperation and exchange,and building digital information sharing platforms are important forces to promote the development of node cities in the Yangtze River Economic Belt.
