With the rapid development of globalization, information and communication technology and high-speed railways, the frequency of element flow has greatly increased, and the comprehensive connection of multiple flow perspectives has become the key to the development of port cities and regions. With the help of GIS, Matlab and Gephi and other technical means, different flow elements are used to analyze the network connection and spatial variation characteristics of China’s coastal port city system in 2006 and 2016. The results show that: 1) In the 5 flow element networks, the total number of element connections between cities has increased and the increase degree has been larger, and the degree of concentration and dispersion and the characteristics of regional distribution have changed significantly. The cyberspace structure of the port city system is transforming from a ‘point axis’ model to a ‘networked’ model. 2) The hub cities with different flow elements have a high degree of overlap, but the network structure has obvious differences. Logistics and passenger flow present the network characteristics of coexistence of ‘group development’ and ‘hub-spoke’. The capital flow and technology flow have developed significant ‘core-periphery’ and hierarchical spatial patterns. Information flow presents a balanced network development model. 3) Different flow elements describe the port city system at different levels, but they are closely related. Logistics and passenger flow affect each other and are cause and effect. The flow of capital and technology has a positive effect on logistics. The impact of information flow on logistics has obvious lag; the port city system has changed from a single flow element to a comprehensive development of multiple flow elements, and the connections between port cities are more diversified, and the interaction and integration with external flow elements have been realized.

Key words: multi element flow, urban network, flow space, port city system
