Studies on Long-term Population Projection for Regions and the Mutual Relationship between Population and Economic Fluctuations

首先，我对大阪府向其他46个县的外迁进行了因果分析。结果表明，交通距离和自然资源丰富度对人口迁移具有负向影响，而生活安全网和养老福利服务的质量对人口迁移具有正向影响。此外，这种趋势对老年一代来说非常显著。其次，研究了24个地区制造业的生产要素冗余度和效率。研究结果表明：日本西部产业相对高效，重点产业存在大量生产要素冗余，包括关东在内的经济规模较大的地区也是如此。

First, I conducted causal analysis of out-migration from Osaka prefecture to other 46 prefectures. The results indicate that transportation distance and abundance of nature had a negative effect on demographic shift, while substantiality of life safety net and old-age welfare services a positive one. In addition, this tendency is very remarkable for the old-age generation. Next, I investigated the efficiency and the redundancy on production factors on 24 manufacturing industries by prefecture. The results show the following : Western Japan industries perform relatively efficiently, large amounts of redundancy on productive factors exist in key industries, and so do the regions, including Kanto, whose economic scales are large.
