Abstract: Since China's reform and opening up in 1978, the Pearl River Delta(PRD)has exerted its advantages in proximity to Hong Kong and Macau, taking the lead in achieving rapid industrialization and urbanization, and has become the most continuous urban area in East Asia. Therefore, it has become more and more urgent to strengthen cooperation and coordinated development among towns and cities. In November 2018, the Central Government of China clearly proposed to establish a new mechanism for more effective regional development and promote regional integration. Through historical research, comparative research and qualitative research, this paper summarizes the evolution of the PRD integration stage and the progress of coordination mechanism construction. Based on the request of the construction of Guangdong-Hong Kong-Macao Greater Bay Area and the improvement of regional governance capacity, this paper puts forward three suggestions to improve the integrated and coordinated development mechanism of the PRD: First, establish a unified spatial development assessment and intelligent management information platform; Second, it’s necessary to establish the "Integration Committee + Task Force" as a decision-making mechanism for the consultation platform; Thirdly, we should establish the inducement mechanism with the Integrated Development Fund as the policy tool.Abstract: Since China's reform and opening up in 1978, the Pearl River Delta(PRD)has exerted its advantages in proximity to Hong Kong and Macau, taking the lead in achieving rapid industrialization and urbanization, and has become the most continuous urban area in East Asia.
