Rural (agricultural and mountainous) depopulation problems in Japan are caused by the over-outmigration into urban areas. The primal factors of the outmigration are not only the rural socioeconomic conditions such as labor and dwelling environments but also the commuting accessibility to urban areas. The over-outmigration does not occur when the commuting accessibility is high, even if the rural socioeconomic conditions are inferior, since they can enjoy the good socioeconomic conditions in urban areas easily. On the other hand, the urban inhabitants who had inmigrated from rural areas will return to their native rural areas, if the rural socioeconomic conditions or the commuting accessibility are improved.The out/in-migration of a person from a rural area is baesd on the evaluation of such his/her life environments. Its process is dynamic and different from each other according to his/her life cycle stage and individual attributes. The effects of countermeasures for rural depopulation problems should be estimated by amount of out/in-migration through such decision making process. Standing on these viewpoints, we have developed a Dynamic Out/ In-Migration Model by using Dimension-Nested and Time-Nested Logit Model.

日本的农村（农业和山区）人口减少问题是由向城市地区过度移民而引起的。移民的主要因素不仅是农村社会经济条件，例如劳动和居住环境，而且是通勤到城市地区的通勤。即使农村社会经济状况较低，通勤可及性很高时也不会发生过度移民，因为它们可以轻松享受城市地区良好的社会经济状况。另一方面，如果农村社会经济状况或通勤可及性得到改善，从农村地区迁移的城市居民将返回其本地农村地区。从农村地区的人口/移民是对他/她的生活环境的评估。它的过程是动态的，并且根据他/她的生命周期阶段和个人属性相互不同。对策对农村人口减少问题的影响应通过此类决策过程来估算出外部/移民的数量。站在这些观点上，我们通过使用维数和时态的logit模型开发了动态的OUT/移民模型。
