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分析了大豆食品加工市场。由于长期以来政府支付制度的不足，大豆食品体系没有充分发挥作用，无法衔接供需关系。这正是国内大豆生产者在过去的有利市场条件下错失增产机会的原因。第二章试图解释当前食糖需求的变化，并阐明其对日本食糖食品体系的影响。作为这一分析的结果，我们明确了以下观点。一是日本国内食糖需求模型的预估时间趋势参数显示，消费者对食糖口味的变化、糖果进口的增加以及食品加工厂的搬迁都对国内食糖需求产生了负面影响。其次，日本食糖需求的减少引发了食糖行业成员之间的一些冲突。最后，我们考虑了两个解决这些问题的措施。一是控制加糖制剂的进口。第三章介绍了一些利用废弃食品和开发利用马铃薯淀粉制成的易分解容器的例子，因为我们需要考虑保护地球环境。第四章考虑产地战略，以维持和发展甜菜、马铃薯、洋葱和玉米的食物系统。我们关注的是与进口原材料和进口加工产品的竞争关系。结果表明，在激烈的国际竞争中，原料产地和加工商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.
