This paper takes the advanced manufacturing industry in Guangdong, Hong Kong and Macao Greater Bay Area and the integrated development of county industrial chain in Guangdong Province as the research object, and takes Tai Po County as the case study to analyse the mechanism of the integrated development of the industrial chain in depth. By exploring the mechanisms of industrial docking and synergistic development, technological innovation and industrial upgrading, infrastructure construction and public service optimisation, policy support and government guidance, as well as enterprise exchange and cooperation and collaborative innovation, it reveals its driving effect on the high-quality development of the regional economy. The results of the study show that the mechanisms of industrial docking, technological innovation, and infrastructure construction have been remarkably effective in promoting the integration and development of the advanced manufacturing industry in the Greater Bay Area and the county industrial chain in Guangdong Province, providing useful reference for other regions in Guangdong Province. With the acceleration of the integration process of the Greater Bay Area, more opportunities will be ushered in the development of county industries in Guangdong Province, and it is of great significance to continue to deepen the integration of the industry chain and promote the development of county industries in the direction of high-end, green and intelligent.
