本研究分析了孤立住宅的时空分布，即，那些没有周围邻居，在日本各地2009年和2014年使用开发的住宅微观地理数据。然后，我们计算的生命线公用事业的维护成本和利益的居民搬迁到市中心。主要结果如下。第一，全国范围内的孤立住房数量有所减少，但孤立住房的比例有所增加，主要是在山区和偏远岛屿。第二，有没有孤立的住宅和老化率之间的关系，根据城市水平的汇总数据;但是，孤立的住宅的老化率高于非孤立的住宅，根据精确的非汇总数据。最后，对生命线公用事业费用和移民促进费用的计算表明，只要移民促进费用为每个孤立住宅1 000万日元（JPY），日本几乎所有的市政府都可以在13年内收回搬迁促进费用。然而，说服居民同意搬迁可能具有挑战性。此外，还应考虑到与世隔绝的住所的好处，即生态旅游、文化价值、传统社会和居住自由。本研究之空间分析与模拟结果，可借由相关团体间之讨论与资讯分享，促进重要之公众参与城市管理。因此，今后的工作将改进计算过程，以促进对可持续城市管理的讨论。
This research analyzes the spatio-temporal distribution of isolated dwellings; i.e., those with no surrounding neighborhood, throughout Japan for 2009 and 2014 using developed residential micro geodata. We then calculate the lifeline utility maintenance costs and benefits in relation to relocating residents to the city center. The main results are as follows. First, the number of isolated dwellings decreased nationwide although the rate of isolated dwellings increased, predominantly in mountainous areas and remote islands. Second, there was no significant relationship between isolated dwellings and aging rate according to municipality-level aggregated data; however, the aging rate of isolated dwellings was higher than that of non-isolated dwellings according to pinpoint non-aggregated data. Finally, calculations of lifeline utility costs and migration promotion expenses indicate that almost all municipalities in Japan could recover relocation promotion expenses in 13 years, provided that migration promotion expenses are 10 million Japanese yen (JPY) per isolated dwelling. However, convincing residents to agree to relocation can be challenging. Moreover, the benefits of isolated dwellings should also be considered; i.e. ecotourism, cultural values, traditional societies, and freedom of residence. The spatial analysis and modeling results of this study can be used to promote vital public involvement in city management through discussion and information sharing among stakeholders. Therefore, future work will improve the calculation process to promote discussion on sustainable city management.
