项目摘要

The purpose of this study is the comparison of the explanatory power to internal long-distance migration in Japan of between regional economic differentials and amenity differentials such as those of environmental amenities and social amenities during the latter half of the 20th century. As we have a few preceding articles on internal migration, we made a lots of basic fact findings. We assume that people' s utility consists of income, environmental amenities and social amenities. We use two main methods; (1)regression analysis using modified gravity model and net migration model and (2)national and prefecutural survey of migration reasons.Main results are as follows."Employment reason" has been one of the most prominent reasons of internal long-distance migration. "Natural environment reason" has not been surveyed by most surveys. Though "family reason" have occupied high ratio on the national survey, this reason has not been given enough attention.The results using modified gravity model and net migration model are as follows. We use migration data between major 10 areas using (1)1970, 1980, 1990 and 2000 national census and (2)Report on Internal Migration in Japan Derived from the Basic Resident Registers from 1955 to 2000. First, per capita real income has generally strong explanatory power during the latter half of the 20^<th> century, but it has been declining gradually. Second, we got a very interesting finding that low average temperature promotes migration both from and to cold areas. The clear evidence, however, that people migrate from cold area to warm area was not found out generally. Third, regional differentials of standard of living measured by People' s Life Indicators affected long-distance migration weakly. Fourth, the effect of the change of age structure to the change of net migration rate of each area was found out to be weak.

本研究的目的是比较20世纪后半叶地区经济差异与环境设施和社会设施等设施差异对日本国内长途移民的解释力。由于我们之前有几篇关于国内移民的文章，我们做了很多基本的事实调查。我们假设人们的效用包括收入、环境舒适和社会舒适。我们使用两种主要方法;（1）利用修正的重力模型和净迁移模型进行回归分析;（2）全国和地方性人口迁移原因调查。“就业原因”已成为国内长距离人口迁移最突出的原因之一。“自然环境原因”在大多数调查中没有被调查。虽然“家庭原因”在全国调查中占有很高的比例，但这一原因并未得到足够的重视。本研究使用了（1）1970年、1980年、1990年、2000年的全国人口普查和（2）1955年~ 2000年的基于基本居民登记的日本国内人口迁移报告的10大地区之间的人口迁移数据。首先，人均真实的收入在20^世纪后半期具有较强的解释力<th>，但它一直在逐渐下降。第二，我们得到了一个非常有趣的发现，低平均温度促进了从寒冷地区和向寒冷地区的迁移。然而，人们从寒冷地区迁移到温暖地区的明确证据普遍没有发现。第三，用人民生活指数衡量的生活水平的地区差异对长距离迁移的影响很弱。第四，年龄结构的变化对各地区净迁移率变化的影响较弱。
