A Study on the Synergistic Mechanism between Industrial Structure Adjustment and Green Development in the Guangdong-Hong Kong-Macao Greater Bay Area

The Guangdong-Hong Kong, China-Macao, China Greater Bay Area (GBA) represents one of China's most dynamic, innovative, and open economic regions, serving as a critical engine for national growth. As it continuously strives for high-quality development, the intricate coordination between industrial structure adjustment and green development becomes an urgent strategic priority. This paper comprehensively investigates the underlying mechanisms through which the GBA can effectively harmonize economic restructuring with long-term ecological sustainability. Drawing on robust theoretical frameworks of ecological economics, environmental management, and regional development, the study systematically analyzes the current state of the regional industrial system. It identifies multifaceted challenges inherent in the green transformation process, such as resource constraints, technological bottlenecks, and institutional barriers. To address these critical issues, the research proposes a comprehensive synergistic mechanism that seamlessly integrates technological innovation, policy frameworks, and extensive cross-regional cooperation. By fostering a circular economy and promoting low-carbon industrial practices, this proposed model aims to optimize resource allocation and mitigate environmental degradation. Furthermore, the study provides actionable policy recommendations to facilitate the transition toward a more resilient and sustainable economic model. Ultimately, this research contributes valuable insights into the spatial and structural dynamics of regional integration, offering a replicable paradigm for other rapidly urbanizing and industrializing regions globally seeking to balance robust economic expansion with stringent environmental preservation mandates.
