Introduction: In response to China’s ambitious dual-carbon goals, this study investigates the spatial correlation and influencing factors of carbon emission intensity within Guangdong-Hong Kong-Macao Great Bay Area (GBA), a region pivotal for nation’s energy conservation reduction efforts. Through comprehensive analysis encompassing period from 2000 2020, research aims delineate dynamics emissions identify actionable insights regional low-carbon development. Methods: Utilizing an integrated methodology comprising autocorrelation analysis, Social Network Analysis (SNA), Quadratic Assignment Procedure (QAP), analyzes data alongside socio-economic variables. These methodologies allow nuanced exploration structure determination across GBA. Results: Findings reveal cyclical fluctuation in network characterized by varying degrees cohesion among cities, indicating significant opportunities optimization. A “core-periphery” pattern emerges, with economically robust cities such as Hong Kong Macao at core, less developed like Huizhou Jiangmen on periphery. Cities Guangzhou Shenzhen play crucial mediator roles. The QAP further identifies six major factors: geographic proximity, economic development level, urbanization rate, industrial configuration, level technological innovation, environmental protection efforts, latter four having markedly positive impact relevance. Discussion: study’s underscore importance understanding role socioeconomic shaping these patterns. For policymakers stakeholders GBA, findings highlight necessity targeted intervention strategies that consider both unique position broader context. This approach can significantly contribute achieving objectives, promoting conservation, facilitating transition economy.

Spatially, ecological infrastructure (EI) is a multi-scale and cross-level network promoting sustainable urban development. Due to the distinct features of different scales, researchers have emphasized importance EI construction, which calls for support from framework scientific evaluation. Thus, based on nature-based solutions (NbS) criteria, this study proposes construction benefits (MECBs-NbS) evaluation with scale differences chooses Guangdong-Hong Kong-Macao Greater Bay Area (GBA) as case study. The results show that: (1) MECBs-NbS fairly applicable; (2) in 2020, building security patterns at macro-scale (GBA agglomeration) by around 203.63 billion RMB; improving human-nature harmony, ecological, physical, social meso-scale (Huizhou city) were about 358.50 while benefit completing engineering tasks micro-scale (site) was 34.85 million (3) overall, built-up area center, decreased, gradually changed being dominated benefits; (4) supporting status quo analysis before assessment following may not only planning, design management EI, but also serve crucial tool encourage public participation evaluate performance government work.
