Evaluation of Comprehensive Development Quality of Port City from the Perspective of Flow Space

Abstract

As an important node of transportation network, it is the mainstream trend to improve the development quality of port city and build a high-quality port city. Based on the perspective of flow space, from the two dimensions of "dynamic" and "static" , this paper explored the characteristics and types of comprehensive development quality of 47 coastal port cities, and put forward countermeasures and suggestions. The results showed that: (1) The comprehensive development quality of each port city formed a relatively reasonable gradient distribution, but the driving role of the core port city and the ability of cooperation and mutual assistance among the port cities needed to be improved; (2) The comprehensive development quality of China's port cities can be divided into four types: very high, high, average and low. The number of low type port cities was much higher than that of very high type port cities, and the comprehensive development quality of China's port cities wa still not optimistic; (3) From the internal point of view of different port urban agglomerations, Bohai Rim, Yangtze River Delta and Pearl River Delta port urban agglomerations were concentrated, complete and homogeneous; (4) The key factors affecting the comprehensive development quality of port cities were technology flow, capital flow, logistics and container throughput
