港口基础设施与港口城市经济互动发展是区域经济可持续和快速发展的重要保障。本文先以连云港港和日照港为例,实证研究了港口基础设施与港口城市经济互动发展的程度。研究表明：港口城市经济与港口基础设施之间存在着很强的关联性;港口基础设施建设较快的港口城市,城市经济发展也较快;不同港口城市,＂港口基础设施-港口城市经济＂关联系统的性质存在着差异。在港口基础设施与港口城市经济互动发展系统中,港口经济承担很重要的角色,是二者互动的节点、界面、载体、枢纽和纽带。接着,分析了港口基础设施智慧化演进背景下,港口基础设施与港口城市经济互动发展的新内涵。智慧港口基础设施、智慧港口经济、智慧港口城市经济互动发展是港口基础设施与港口城市经济互动发展的新机制。

英文摘要：

The interactive development of port infrastructure and port city economy is an important guarantee for promoting sustainable and rapid economy development of a region. Firstly,this paper studies the quantitative relationship of the interactive development of port infrastructure and port city economy based on the case of Lianyungang port and Rizhao port. The results indicate that there is a closer correlation between port city economy and port infrastructure,the economy of the port city in which port infrastructure constructed more quickly grows more rapidly,the port infrastructure-port city economy interactive development systems are distinct between different port cities. In the port infrastructure-port city economy interactive development system,port economy plays an important role of the node,the interface,the carrier,the hub,and the vinculum. Then,this paper analyzes the new meanings of the interactive development of port infrastructure and port city economy under the background of port infrastructure intelligent development. The interactive development of intelligent port infrastructure,intelligent port economy,and intelligent port city economy is a new mechanism of the interactive development of port infrastructure and port city economy.
