## 6 Discussion and Conclusions  
### Discussion  
This study aims to deeply explore the spatial and temporal distribution evolution and sustainable development mechanisms of the GIS-based smart healthy ageing demonstration base. Through GIS technology, we track the changes in the spatial and temporal dimensions of the Smart Healthy Aging Demonstration Base and deeply analyze the rationality of its spatial layout, the evolution of its geographic characteristics, and its impact on the surrounding environment. We aimed to explore the sustainable development mechanism of the Smart Healthy Aging Demonstration Base in terms of economic, social, and environmental aspects to establish a comprehensive theoretical framework that will lead the base to balance economic benefits, social responsibility, and environmental protection in the long term. The closest neighbour index method was used to analyze the agglomeration of the bases; the spatial extent was analyzed by Tyson polygons; the hotspot distribution of the bases was examined by applying kernel density; and the aggregation characteristics of the distribution of the bases were examined by spatial autocorrelation analysis. A quantitative analysis based on the aforementioned research framework yields detailed spatial analysis results, effectively quantifying the characteristics of regional spatial relationships, such as the balance, disparities, and patterns of agglomeration within the distribution of smart healthy ageing demonstration bases across 31 Chinese provinces. The visual representation of graphical data enhances the intuitiveness and readability of the research findings. Utilizing a combination of diverse analytical methods, this study showcases the spatiotemporal distribution characteristics of China's intelligent healthy ageing demonstration bases from varied perspectives, thereby facilitating a comprehensive and precise assessment of the spatial and temporal distribution of the ageing demonstration bases and augmenting the scientific and persuasive nature of the study. It offers novel perspectives for appraising the development of China's intelligent, healthy ageing demonstration bases and furnishes scientific argumentation to uphold the research findings. It was found that China's intelligent healthy ageing bases are spatially clustered, and the clustering areas are mainly located in the central and eastern parts of China, with Zhejiang, Sichuan, and Shandong provinces and regions being the most significant. The bases as a whole show a spatial pattern of the \"three-pole concentration-multi-core encircling type\". The spatial correlation Moran I index increased from 0.011 in 2017 to 0.116, a nearly 10-fold increase, indicating that China's intelligent, healthy ageing bases also have a certain degree of spatial correlation on the whole. Finally, the study proposes that the market power development mechanism, the policy power development mechanism, the technology power development mechanism, and the other \"three major power\" mechanisms correspond to each other and continue to promote the construction of wisdom to realize the sustainable development of the demonstration base. This study provides a scientific basis for the planning layout and industrial development of relevant departments. Compared with previous studies, this study analyzes the relationship between the base and the surrounding environment in more detail using GIS technology and digs deeper into the potential impact of spatial layout on the service effect. It pays more attention to the analysis of sustainability, emphasizing the important significance of comprehensively promoting the establishment and sustainable development of the sustainable development mechanism of the demonstration base for smart healthy ageing from the three aspects of the market-powered development mechanism, the policy-powered development mechanism, and the technological-powered development mechanism, improving the quality of life of the elderly and promoting the harmony and stability of society.
