A Study on the Dynamic Process and Development Conditions of Food System under the Structure Reform

第一章从食品系统的角度对食品加工用大豆市场进行了分析。长期以来，由于政府支付制度的缺失，大豆粮食制度没有充分发挥作用，不能有效地联结供求关系。这就是为什么尽管过去的市场条件很好，但国内大豆生产商却错过了增产的机会。第二章试图解释目前糖需求的变化，并阐明其对日本糖食品体系的影响。通过分析，我们明确了以下几点。首先，根据日本国内食糖需求模型的时间趋势参数推算，消费者对食糖口味的变化、糖果进口的增加、食品加工厂的搬迁等对国内食糖需求产生了负面影响。其次，日本对糖的需求减少，引起了糖食品行业成员之间的一些冲突。最后，我们考虑了解决这些问题的两项措施。一是控制加糖制剂进口。第三章介绍了一些利用废弃食品和开发易分解的马铃薯淀粉容器的例子，因为我们需要考虑保护地球环境。第四章考虑了生产地区的战略，以维持和发展甜菜，马铃薯，洋葱和玉米我们专注于进口原材料和进口加工产品的竞争关系。结果表明，在严格的国际竞争条件下，原料产地和加工企业需要认识到彼此之间的共生关系。

Chapter 1 considered the soybean market for food processing from the point of food system. Because of the deficiency payment institution by the government for long period, the soybean food system does not have worked sufficiently so as it can link demand-supply relationships. This is the very reason that the domestic soybean producers have missed the chance to increase their production in spite of the past favorable conditions of the market.Chapter 2 attempts to explain the current changes in the demand for sugar and to clarify its influence on the Japanese sugar food system. As a result of this analysis, we have made clear the following ideas. First is that the estimated time trend parameter of Japan's domestic sugar demand model shows that the change of consumers' taste for sugar, the increase in confectionery imports, and the relocation of food processing plants have negatively affected the demand for domestic sugar. Second is that a decrease in the demand for sugar in Japan has raised some conflicts amongst members of the sugar food industry. Finally, we consider two measures to solve these problems. One is to control the importation of sugar-added preparations. The other is to lower the domestic sugar price in order to compete more effectively against sugar-added preparations.Chapter 3 introduced some examples of utilization of waste food and development of a container made of potato starch which can be decomposed easily, because we need consider to keep the earth environment.Chapter 4 considered strategies of producing areas in order to maintain and develop the food systems for beet, potato, onion and corn. We focused on competitive relationship against import raw materials and import processing products. As a result, it was shown that material producing areas and processors need to recognize symbiotic relationship each other under the strictly international competition.
