18 February 2022 marks the 3rd anniversary of the promulgation by the State Council of the "Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area". GBA has by now become the catchword whether in government, business or professional sectors. The Outline Plan sets out 5 big goals in strategic positioning: a vibrant world-class city cluster; a globally influential international innovation and technology hub; an important support pillar for the Belt and Road initiative; a showcase for in-depth cooperation between the Mainland and Hong Kong and Macao; and a quality living circle for living, working and travelling. Joint efforts in "going global" are emphasized, to enable the GBA to play a leading role in international cooperation. It is a tall order. This Policy Dialogue examines how Hong Kong can leverage its institutional strengths and key resources in taking advantages of the GBA platform to foster economic transformation and shape a stronger future. New opportunities emerge out of GBA integration and collaboration, but there also exist challenges and threats.
