### Theoretical and Practical Significance  
This study expands the concept of the CGSP to the community level, addressing a gap in research on community-level CGSP and introducing an innovative micro-level theoretical research model. This expansion not only provides theoretical support for the CGSP system at the micro level but also creatively applies the TAO Three-Way Decision model to a digital platform, demonstrating its applicability within the community CGSP digital platform. The deep integration of this model with the platform enhances the theoretical methods and outcomes of model-platform integration, offering new directions for digital scientific decision-making systems. This research highlights the potential advantages of combining community CGSP with digitalization, opening up new avenues for research in related fields. From the perspective of social development, the community CGSP system proposed in this study facilitates residents' adoption of low-carbon lifestyles through the collaborative efforts of government, community organizations, and social enterprises, offering an innovative implementation pathway for community-level CGSP. By quantifying residents' carbon reduction behaviors and combining these efforts with both spiritual and material incentives, the system continuously encourages low-carbon practices, thereby enhancing the overall emission reduction effectiveness at the community level. Furthermore, this research provides community managers with an operational CGSP mechanism, helping them formulate more efficient emission reduction and incentive measures, raising environmental awareness among residents, and fostering the development of low-carbon behaviors and environmentally friendly lifestyles. The study offers a new paradigm for carbon reduction strategies in the context of digital transformation, with broad social application prospects. Comparison of Community Carbon Generalized System of Preferences and Traditional Carbon Generalized System of Preferences  
Although the development of CGSP in developed countries is quite advanced, research and practice focusing on community-level CGSP systems remain relatively limited. In recent years, several countries have conducted research on CGSP, but significant differences exist in the specific measures and the scope of low-carbon behaviors. For instance, since 2008, South Korea has promoted voluntary participation in low-carbon behaviors by individuals and households through its \"Carbon Bank\" system, which quantifies spontaneous water, electricity, and gas conservation behaviors and provides positive economic

However, this system mainly focuses on specific sectors of the CGSP. In 2009, Japan introduced the \"Eco Points\" system, relying primarily on market forces to guide public participation and incentivize household carbon reduction behaviors [51]. France and the United Kingdom have also conducted some community-level CGSP initiatives within their respective policy frameworks, but overall, these efforts have been limited in achieving systematic low-carbon emission reductions at the community level [52; 53; 54]. Therefore, despite significant progress in CGSP in developed countries, community CGSP is still in its early stages, and there is a need for further in-depth research on systematic and comprehensive community CGSP. In contrast, China's CGSP practices have mainly been concentrated in specific regions, with a lack of systematic research at the community level. Existing platforms face limitations in covering low-carbon behaviors and involving resident participation.
