There is an inseparable relationship between the SDGs' goals, including a synergistic relationship and a trade-off relationship. This study aims to clarify the nexus structure of the SDGs with respect to the extension of healthy life expectancy. In addition, using the constructed network structure, we estimate healthy life expectancy based on the SSP scenarios and indicate which goals prioritize extending healthy life expectancy. The results show that social area such as Goal 1 are efficient for extending healthy life expectancy, but they also have many trade-offs and require careful policy choices. On the other hand, environmental area, such as Goal 13, do not significantly impact the primary effect but may have a stronger influence on the secondary outcome because they have the most synergistic relationships and fewer trade-offs. The future projection results also show a decrease in healthy life expectancy, even in the SSP1 scenario. Therefore, the results indicate that improving goals 13 and 15 is particularly important to increase healthy life expectancy. In summary, to increase healthy life expectancy and achieve the SDGs, it is essential to promote policies that achieve environmental area in parallel with social area.
