港珠澳大桥影响下粤港澳大湾区经济空间新变化

Changes in the Economic Space of the Guangdong-Hong Kong-Macao Bay Area Under the Influence of the Hong Kong-Zhuhai-Macao Bridge

港珠澳大桥是连接香港、澳门与珠海的跨海大桥,是一项重要的交通运输基础设施,其建成通车对粤港澳大湾区经济空间格局产生重大的影响。基于超制图学的方法,建立模型将时间距离换算成公里为单位的空间距离,在此基础上利用Arc GIS软件进行投影空间变换以及橡皮拉伸方法,用换算出的距离重新定义两地间距离,对原空间地图进行变换,得出时间距离制图,结果发现:港珠澳大桥的通车让澳门、珠海与香港呈现"接壤"关系,珠海市政府和澳门特区政府与香港特区政府的时间距离比深圳市政府与香港特区政府的距离更短;大桥的通车将改变香港与珠海的城市经济空间格局,让香港城市经济空间更加均衡;同时也使得大湾区的相关产业实现了空间优化配置与重组,区域产业空间聚集效应增强,区域产业进一步专业化。

The Hong Kong-Zhuhai-Macao Bridge is an important cross-sea transportation infrastructure connecting Hong Kong,Macao and Zhuhai.Its completion and opening to traffic has brought significant changes to the economic spatial pattern of the Guangdong-Hong Kong-Macao Bay Area.Based on the method of cartography,time range is convert into the unit of space distance.Meanwhile on the basis of projection space transformed by using ArcGIS software and rubber stretching method,and with the conversion of the distance to define the distance between the two places,we are able to map to the time distance among spaces.Results showed that:the Bridge make Zhuhai“closer”to Macao and Hong Kong in terms of time space,even closer than the distance from Shenzhen municipal government to Hong Kong SAR government;the opening of the bridge will change the urban economic space pattern of Hong Kong and zhuhai and make the urban economic space of Hong Kong more balanced.It has also made relevant industries achieve the spatial optimization and reorganization,the regional industrial spatial aggregation effect enhanced,and the regional industry further specialized.
