Cao, L., 2020. Changing port governance model: Port spatial structure and trade efficiency. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 963-968. Coconut Creek (Florida), ISSN 0749-0208.

The port governance mode is divided into port spatial structure and information construction. Through the optimization of port governance mode, improving trade efficiency and smooth information of port waterway, it is the basis of orderly promotion of waterway transportation, which is closely related to the development of port waterway hub, establishes a perfect port engineering information system, and realizes the construction of customer group of port spatial structure management project. To realize the integrated development of customer informatization and the informatization level of port spatial structure management project, the whole operation quality and efficiency of port spatial structure management project are directly related to the whole operation quality of port spatial structure governance project. Therefore, port units should increase the investment in information construction and promote the smooth realization of the goal of information construction. We will continue to deepen the work of energy conservation and emission reduction in the port industry. To complete the task of port energy saving and emission reduction and to ensure the realization of the goal of energy saving and emission reduction, the most fundamental thing is to establish a long-term mechanism for the development of low-carbon green ports, promote the benign interaction between ports and foreign trade, and actively expand the service depth of the hinterland economy. Further strengthen the cooperation between Beijing, Tianjin and Hebei port groups, realize the optimal allocation of cargo source structure, constantly increase port logistics infrastructure investment, especially container terminal investment, constantly optimize and enhance the port logistics industry, develop modern new port logistics, speed up the transformation and upgrading of port logistics, and promote the mutual promotion of port economy and foreign trade. The analysis shows that the adoption of optimized seaport governance model can promote trade growth.
