山东省区域港口与经济发展的互动效应分析

以烟台港、青岛港、潍坊港、东营港、日照港等8个山东典型港口为研究对象，充分考虑山东半岛、渤海湾及鲁南地区发展的特殊性，结合山东省港口资源整合的大环境及各港口经济发展现状，综合剖析区域港口之间的差别及组建港口联盟的必要性。在此基础上，对2011年至2017年山东各港口的相关面板数据进行向量自回归，分析港口与经济发展间的相互作用，并通过固定效应回归模型，进一步研究具体因素对区域港口发展的影响。研究发现，区域港口与经济发展之间存在互动效应，且港口对经济发展的贡献程度要强于经济的反向影响。具体来看，地区经济水平、产业结构及基础设施等异质经济因素对山东区域港口发展具有显著影响。

Analysis on the interactive effect of Shandong regional ports and economic development

Eight typical ports in Shandong (e.g. Yantai, Qingdao, Weifang, Dongying, Rizhao) are studied in this paper. By fully considering the particularity of the development of Shandong Peninsula, Bohai Bay and the southern areas；in light of grand environment of port resource in Shandong Province; and the status quo of port development, thereof, this paper analyses the differences between regional ports and the necessity of forming port alliance. On this basis, the relevant panel data of Shandong regional ports from 2011 to 2017 are analyzed using vector auto-regression, the interaction between ports and economic development are analyzed, the influence of specific factors on regional port development through fixed effect regression model are further analyzed. The study finds that there is an interactive effect between regional ports and economic development, and the ports-to-economic contribution is stronger than economy-to-port contribution. Specifically, the regional economic level, industrial structure and infrastructure, and other heterogeneous economic factors have significant impacts on the development of Shandong regional ports.
