粤港澳大湾区港口效率与产业结构升级耦合协调时空演化分析

Spatial and Temporal Evolution Analysis of Coupling Coordination between Port Efficiency and Industrial Structure Upgrading in Guangdong⁃Hong Kong⁃Macao Greater Bay Area

为分析粤港澳大湾区港口与产业结构升级关系,运用超效率SBM模型和熵值法分别测度了粤港澳大湾区港口效率和产业结构升级水平,通过耦合协调度模型分析了两者之间的耦合协调度及其时空演化.结果显示:2011—2020年粤港澳大湾区港口效率整体呈倒“N”形,产业结构升级水平呈不断提升趋势;大部分的港口效率与产业结构升级耦合协调水平不断提升,粤港澳大湾区港口效率与产业结构升级耦合协调水平呈“沿海高、内河低”的空间分布格局.

In order to analyze the relationship between ports and industrial structure upgrading in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area,use the super⁃efficiency SBM model and the entropy method to measure the port efficiency and industrial structure upgrading level respectively in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area,and then employ coupling coordination degree model to analyze the coupling coordination degree and its spatiotemporal evolution.The results show that:(1)From 2011 to 2020,the port efficiency in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area is in an inverted“N”shape,and the level of industrial structure upgrading is on the rise;(2)the level of coupling and coordination between the efficiency of most ports and the upgrading of industrial structure is constantly increasing.The level of coupling and coordination between port efficiency and industrial structure upgrading in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area shows a spatial distribution pattern of“high coastal areas and low inland rivers”.
