粤港澳大湾区港口对泛珠三角主要城市吸引力及其空间结构演化分析

Analysis on the Attractiveness of the Ports in the GBA to the Main Cities in the Pan-Pearl River Delta and Its Spatial Structure Evolution

构建粤港澳大湾区港口规模评价指标体系,并采用熵值法对粤港澳大湾区各港口规模进行度量,应用Huff模型构造粤港澳大湾区港口对泛珠三角主要城市的吸引力模型.在此基础上,研究粤港澳大湾区港口与泛珠三角主要城市在战略合作背景下吸引力的空间结构发展和空间演化趋势.研究表明:泛珠三角主要城市与粤港澳大湾区港口群之间吸引力网络结构由“广州港—深圳港—香港港”的“铁三角”格局,逐步转变为“广深港为核心、莞佛肇为支撑”的多边连接关系;各港口吸引力空间发展格局也从“东高西低”“南北两头高”逐步演化为“东陡西缓”“北高南低”;局部港口城市优势明显,珠江东西岸发展不均匀仍存在.

The evaluation index system of port scale in Guangdong-Hong Kong-Macao Greater Bay Area is constructed,and the entropy method is used to measure the scale of each port in the GBA,the Huff model is used to construct an attractive model for the ports in the GBA to the main cities in the Pan-Pearl River Delta.On this basis,the spatial structure development and spatial evolution trend of the attractiveness of the ports in the GBA and the main cities in the Pan-Pearl River Delta under the background of strategic cooperation are studied.The research shows that the attractive network structure between the ports in the GBA and the main cities in the Pan-Pearl River Delta has gradually changed from the“iron triangle”pattern of“Guangzhou Port-Shenzhen Port-Hong Kong Port”to a multilateral connection with“Guangzhou,Shenzhen,Hong Kong as the core and Dongguan,Foshan,Zhaoqing as the support”.The spatial development pattern of the attractiveness of the ports has gradually evolved from“high in the east and low in the west”“high in the north and south”to“steep in the east and slow in the west”“high in the north and low in the south”.However,there are obvious advantages of some port cities and uneven development on the east and west banks of the Pearl River.
