In the Greater Bay Area (GBA), each city has a specific role and mission that is tailored to its unique competitive advantages, and economic development in the region is helping to promote the free flow of capital, goods and people.

The open market landscape of the GBA's two special administrative regions, Hong Kong and Macau, provides an example for the nine cities in the Pearl River Delta as they work together to further open up and create a globally competitive business environment. Hong Kong enjoys the advantage of being the GBA's global financial hub with open access to the world's capital and financial markets and a significant pool of executive talent.

Furthermore, Hong Kong, Macau and the nine cities in the Pearl River Delta share a similar culture, and most of the residents can communicate in English, Putonghua and Cantonese. The development of smart cities, convenient transportation, and individual income tax concessions are also helping to attract high-end talent to work in the region.
