Guangdong-Hong Kong-Macao Greater Bay Area is a city group consisting of two special administrative regions of Hong Kong and Macao and nine cities including Guangzhou, Shenzhen and Zhuhai. Zhang Siping, former member of the Standing Committee of Shenzhen Municipality and deputy mayor, said that although the country’s overall plan for the Dawan District has not yet been announced, the special geographical location determines its importance in global competition, and it is one of the four largest Bay Areas in the world together with the New York Bay Area and San Francisco Bay Area and Japan's Tokyo Bay Area.

　　

　　The special characteristics of the Guangdong-Hong Kong-Macao Greater Bay Area are one country, two systems, two special administrative regions, and two special customs zones. Zhang Siping said that Dawan is divided into two parts, one is the main area of the world manufacturing and international multinational enterprises, and the largest foreign trade import and export center in China, including nine major cities of the Pearl River Delta in the process of internationalization; The other part is a cosmopolitan city that has long been closely linked to the world economy and global integration, and is a separate special customs zone and free port of Hong Kong and Macau.

　　

　　The distance between the two regions is not only the distance and the degree of internationalization, but the "two systems." Zhang Siping believes that the isolation of the system is caused by physical isolation and information isolation. There is a strict border management system between the two, and the goods between them are difficult to circulate. “This may be an important constraint on the planning and construction of the Guangdong-Hong Kong-Macao Greater Bay Area.”

　　

　　Despite the hustle and bustle, there is no doubt that the unique advantages of Hong Kong's financial, trade and shipping centers will drive the development of the Greater Bay Area. Zhang Siping suggested that in order to give full play to the unique advantages of Hong Kong and Macao, some mechanisms, institutional policies and some systems in the special system of Hong Kong and Macao will be extended to the Pearl River Delta to promote the integration of the Pearl River Delta and Hong Kong and Macao and promote the internationalization and globalization of the entire Dawan District.
