Industrial Structure in Depopulated Area and Effectiveness of Development Policies

为了分析产业结构的特点和中央政府制定的开发政策的有效性，我们对人口减少地区奄美群岛进行了调查。我们不仅收集了许多研究资料，还就这个问题与许多人进行了辩论，并多次召开学习会。我们的主要研究结果如下：1.奄美群岛的国内贸易收支一直处于赤字状态。红色数字还得到了政府补贴的补充。2.在日本经济高速增长时期，大量的农民流向大城市，成为“溢出人口”。如今，老年人的比例急剧增加，年轻劳动力短缺。3.甘蔗制糖业一直是奄美群岛的支柱产业，但问题很多。其中之一是生产率的下降。4.由于市场需求减少、年轻织工短缺、韩国大量产品流入等原因，大岛纺织业（丝织业的一种）正在走向衰落。为促进奄美群岛产业发展而制定的政府政策存在许多缺陷。最重要的是，阿马尼群岛的居民应该为自己的利益制定一个全面的计划。

We investigated the depopulated area, the Amami Archipelago, in order to analyze the character of industrial structure and the effectiveness of development policies which had been formulated by the central government. We not only collected many research materials, but also debated many people on the subject and held the study meeting many times. And we published the results of our research works.Our main findings on the research study are as follows. 1. The balance of payments of the domestic trade of the Amami Archipelago has always been in red. And the red figures has been supplemented by the government' subsidy. 2. Many peasants , who were "overflowing population", flowed out to the big cities in the period of high growth of Japanese economy. And nowadays, the proportion of old aged people is drastically increasing, and young labor forces are in a shortage. 3. Cane sugar industry , which has been a key industry in the Amami Archipelago has many problem. One of them is the decrease of productvity. 4. Oshima-tsumugi industry ( a kind of silk fabric industry ) is now on declined, because of parid reduced demand a shortage of young weavers, an inflow of many products mitic in Korea and so on. 5. The government policies, which has been formulated to promote the development of industries in the Amami Archipelago, has many defects. It is most important that a comprehensive should be made up by the inhabitants of the Amani Archipelago for their own sake.
