As a strategic resource for the region to participate in global economic cooperation and competition, the coordinated development of ports within the port group is of great practical significance to promote its own and regional economic development. In order to better promote the port’s rational development and resource allocation, this paper uses the rough set reduction method based on information entropy to determine the attribute weight and importance of the system order parameter index and uses the port group system coupling measure model to obtain the port coupling degree. Then, different coupling states are distinguished according to the coupling degree of the port, and the level of the coordinated development of the port is described. Finally, through the empirical analysis of the three major port groups in the Bohai Rim region, the level of coordinated development of ports within the three major port groups is analyzed.

作为区域参与全球经济合作与竞争的战略资源，港口群内港口的协调发展对促进自身和区域经济发展具有重要的现实意义。为了更好地促进港口的合理发展和资源配置，本文采用基于信息熵的粗糙集约简法确定系统阶序参数指标的属性权重和重要性，并利用港口群系统耦合测度模型获得港口的系统合理性。端口耦合度。然后，根据端口的耦合程度区分不同的耦合状态，并描述端口的协调发展水平。最后，通过对环渤海地区三个主要港口群的实证分析，
