本研究以大坂都市圈周边地区的居住区类型为对象，探讨步行性对城市可持续性的影响。为此，本研究分析了步行指数和生态足迹与生物承载力（EF/BC）的比例之间的统计因果关系的每个住宅集群。生态足迹/生物承载力比率是居住区集群的生态足迹与生物承载力的比率。因此，步行性对城市可持续性的影响取决于大坂都市圈边缘地区的住宅集群的类型。具体而言，人们发现，步行指数的负面影响的EF/BC比率在蔓延集群。这表明，在无规划集群中，积极努力提高步行指数可以有助于实现SDG（2030年议程的可持续发展目标）。然而，步行指数有很强的积极影响的EF/BC比在旧的新城集群等，对于住宅集群，本研究的结果表明，有必要通过改善步行能力以外的方法来提高城市的可持续性。
This study aimed to clarify the effect of walkability on urban sustainability, according to the types of residential clusters in the Osaka Metropolitan fringe area. For this purpose, this study analyzed the statistical causal relationship between the Walkability Index and the Ecological Footprint to Biocapacity (EF/BC) ratio of each residential cluster. The EF/BC ratio is the ratio of the ecological footprint of the biocapacity of the residential clusters. As a result, the effect of walkability on urban sustainability was clarified depending upon the types of residential clusters in the Osaka Metropolitan fringe area. Specifically, it was found that the Walkability Index negatively affects the EF/BC ratio in the sprawl cluster. This suggests that, in the sprawl cluster, active efforts to improve the Walkability Index can contribute to the realization of SDGs (Sustainable Development Goals of the 2030 Agenda). However, Walkability Index has a strong positive effect on the EF/BC ratio in the old new-town cluster, etc. For the residential clusters, the results of this study suggested that there is a necessity to improve urban sustainability through approaches other than improving Walkability.
