摘要
为更好地研究港口物流与区域经济协同发展的相互关系,构建港口物流与区域经济指标体系,选取2007~2016年重庆市港口物流与区域经济指标的相关数据,运用灰色关联度模型(GRA),实证分析了重庆市港口物流与区域经济之间的内在关系.结果表明,两者之间存在较高的关联性.为进一步分析二者协调性,采用极值变换法、熵值赋权法、综合发展水平评价模型、耦合度模型、耦合协调度模型进行评价,结果显示二者协同发展水平较高,表明了评价指标体系和模型选取的有效性.最后根据分析结果提出相关发展建议,以期为重庆市港口物流与区域经济发展提供决策依据.
In order to study the relationship between port logistics and regional economic development,in this paper the port logistics and regional economic index system is constructed by selecting the relevant data and economic indicators of Chongqing city from 2007 to 2016.The gray correlation model(GRA)is used for empirical analysis of the internal relationships.The results show that there is a high correlation between the port logistics and regional economy in Chongqing.Further analysis is conducted on the coordination of the two aspects using the extreme value transformation method and entropy weighting method.The study indicates the validity and effectiveness of the evaluation index system and the model selection.On the basis of the analytical results,some suggestions are given for further improvement and development of port logistics and regional economy.
