## 6 Discussion and Conclusions
### Shortcomings and Prospects  
The GIS-based smart healthy ageing demonstration base is a hot spot of current social concern because it combines technology and healthy ageing to provide a better quality of life for the elderly. However, despite the progress made in this study, there are still shortcomings in the research. The spatial and temporal distribution and sustainable development mechanisms of smart healthy ageing demonstration bases need a large amount of data support, but the completeness and quality of the current data are still problematic, limiting the accuracy and feasibility of decision-making. The connotation of smart ageing development is not explored deeply and comprehensively enough in the study. The construction of a demonstration base for smart, healthy ageing needs to be further improved. The future policy recommendations for smart ageing that can be concretized and operable are not strong. When analyzing the sustainable development mechanism, the market power development mechanism, the policy power development mechanism, and the technology power development mechanism from three aspects comprehensively promote the establishment of the sustainable development mechanism and sustainable development of the intelligent healthy ageing demonstration base. However, the potential limitation is the complexity of environmental variables. There are numerous environmental factors affecting the sustainable development of the base, including climate change, geological conditions, etc., and the interplay of these factors may be beyond the scope of the study, leading to difficulties in grasping environmental sustainability in a comprehensive manner. Another potential limitation is the sample bias. The sample points are 89 smart healthy ageing demonstration bases, and the number of new demonstration base points will continue to be announced, which may not be sufficient to represent the diversity of the industry as a whole. The generalization of the study's findings may be limited by sample selection due to regional differences and the diversity of senior care bases. Another limitation is that future uncertainties, such as policy changes and economic fluctuations, which may have a significant impact on the development of smart senior living bases, were not adequately addressed, and the future uncertainties may affect the feasibility and usefulness of the study. When collecting and analyzing the spatial and temporal distribution data of GIS-based smart healthy ageing demonstration bases, the privacy of individuals or organizations may be involved. Therefore, this study fully considers and follows the relevant privacy regulations and ethical guidelines. In future studies, the key factor of protecting data sensitivity and ensuring that the research is conducted within a responsible and ethical framework will be fully considered. Regarding the existence of social justice issues that should be taken into account in the study, the analysis of GIS may reveal differences between different regions, which may involve issues such as socio-economic status, resource allocation, and so on. Therefore, unjust qualitative or quantitative evaluations of certain communities or groups should be avoided in future research to avoid reinforcing social inequalities. The potential impact of these ethical considerations is a key factor in ensuring that research is conducted within a responsible and ethical framework. Therefore, ethical principles should always be placed at the core of research practice to ensure the sustainability and social value of research. In the future, in subsequent eras, the completeness of data may be augmented by the establishment of additional data collection facilities and data-sharing mechanisms with the aim of bolstering more precise decision-making and advancement. The propagation of intelligent, salubrious ageing technologies across diverse regions could be facilitated through instruction and technical support to attain a harmonious evolution in elderly care services.
