Analysis of Interactive Relationship Between Shipping Center and City Economy：A Comparison Between Shanghai and Singapore

Abstract:

The coordinated development of the port-city economy can enhance the competitiveness and influence of the port. This paper conducts a comparative analysis between the international shipping centers of Shanghai and Singapore. Employing the entropy weight-gray correlation model and the vector autoregressive model， it examines the interactive relationship between the port and the city， focusing on foreign trade， gross product value， and industrial structure. The findings reveal a strong correlation within the port-city economy. In Singapore， foreign trade and port exhibit a stable two-way promotion effect， whereas the export-oriented economy in Shanghai has a modest driving effect on the shipping center. The GDP of Shanghai emerges as a pivotal support for the port， although the radiating effect of the shipping center on GDP appears less pronounced. A long-term driving force is identified between tertiary industry and the port in Shanghai. The secondary industry in Shanghai exerts a predominant influence on the shipping center. Therefore， policies promoting the expansion of the tertiary industry demonstrate a more potent influence on the shipping center than those favoring the secondary industry. Based on the conclusions， it proposes some suggestions， such as bolstering port resilience and integrating port-industry-city development.
