The port is the transportation field with the highest degree of marketization in China. At present，a planning system combining development strategy，spatial planning and development planning has been gradually established. In particular，as a statutory planning system，port layout planning and port overall planning have effectively guided the development and construction of China’s ports in the past decades. In recent years，with the influence of factors such as the integration of port resources，the precision management orientation of the industry，and the increasingly complex coordination of territorial space resources，port spatial planning is currently facing many problems such as complex content and inconvenient management，which is difficult to reflect the national will and implement the corresponding authority in the context of comprehensively deepening the reform. The framework system of port planning is systematically combed to solve the outstanding problems in the preparation and implementation of the current port master plan.The concept of combining rigidity with flexibility in the planning process is explored，and the port planning principles and relevant countermeasures in the new era are proposed，so that the port planning can better serve and respond to the actual needs of local government governance and regional economic development while reflecting the national will，and truly realize the planning guided development.
