日照市港口物流与城市经济互动发展关系研究
Research on the Interactive Development Relationship between Port Logistics and Urban Economy in Rizhao City

港口物流作为一个综合物流体系和与外部经济互动的窗口，对城市经济发展具有不可替代的重要作用，因而探究港口物流与城市经济的互动发展关系逐渐成为当下的热点问题。本文选取日照市作为研究对象，以港口货物吞吐量、集装箱吞吐量衡量港口物流发展状况，以日照市地区生产总值(GDP)衡量城市经济发展水平，对日照市港口物流与城市经济的关系进行多元线性回归分析。回归结果表明，港口物流与城市经济之间存在显著的相互促进关系。最后，根据回归结果，结合现实因素，提出在海洋强国战略背景下，日照市应优化港口物流发展模式，加强港口物流与城市经济之间的互动发展，并给出相应的对策与建议。
As a comprehensive logistics system and a window for interaction with the external economy, port logistics plays an irreplaceable and important role in urban economic development. Therefore, exploring the interactive development relationship between port logistics and urban economy has gradually become a hot issue at present. This paper selects Rizhao City as the research object, measures the development status of port logistics by port cargo throughput and container throughput, and measures the level of urban economic development by Rizhao City’s gross regional product (GDP), and then the relationship between port logistics and urban economy is analyzed by multiple linear regression. The regression results show that there is a significant mutual promotion relationship between port logistics and urban economy. Finally, according to the regression results, combined with practical factors, it is proposed that under the background of the strategy of marine power, Rizhao City should optimize the development mode of port logistics, strengthen the interactive development between port logistics and urban economy, and give corresponding countermeasures and suggestions.
