Exerting and promoting "the precise connecting function" is an important part of Macao's long-term development strategy, and is the fundamental assurance of "nation's needs, Macao's specialities" and practice of "one country, two systems" in China's new development era. To meet the challenges from land, industries, regional cooperation, talents and so forth, Macao needs to strengthen the advantages and regional coordination, and to exert strategy of precise connection, precise striving, precise governance and smart growth. By doing so, Macao can promote "the precise connecting function" to a high level, comprehensively and deeply participate in the development of Guangdong-Hong Kong-Macao Greater Bay Area, and can connect to national development.
