A Study on Dynamic Process of Food Systems by Economics of Complex Systems

这个项目有三个主题。首先是食品系统研究中复杂系统经济学的研究。二是运用复杂系统经济学对粮食系统结构变化过程的研究。三是基于复杂系统经济学的粮食系统空间变化研究。结果表明：(1)从复杂系统经济学的角度把握粮食系统是必要的。特别是复合体理论中的“噪声”和“涌现”对研究食物系统非常有用。(2)分析了牛奶、牛奶加工和小麦的食品系统。Yukijirusi nyukyo的食物中毒是由于在利润下降的情况下停电而发生的。这件事的发生似乎有很多原因。它们并不简单，而是复杂的。复杂条件下，粮食安全体系是必要的。在北海道生产牛奶加工用的牛奶，有消弭饮用牛奶市场“噪音”的作用。牛奶加工机构支持这一职能。食品管制制度切断了小麦生产者和小麦加工商之间的关系，以保护小麦生产者。它造成了供给和需求之间的不匹配。粮食系统由资源生产者、加工者、分销商和消费者组成。只有其中之一组成的粮食系统是不可能存在的。如果一个机构只保护其中的一个，就会在系统中产生一些问题。食品系统制度的设计者并没有意识到这一点。(3)分析食品行业区位波动。积累力作用于食品行业的区位波动。技术产生于出现，并在粮食系统中产生噪音。研究了几种淀粉技术的特点及其在冷冻食品中的应用。

This project has three subjects. First is a study on economics of complex systems for food system research. Second is a study on the process of structural changes of food systems by economics of complex systems. Third is a study on spatial changes of food systems by economics of complex systems.The results of this project are as follows:(1) It is necessary to grasp food systems by economics of complex systems. Especially, 'noise' and 'emergence' on the theory of complex are useful for studying on food systems.(2) The food systems of milk and milk processing, and wheat are analyzed. The food poisoning of Yukijirusi nyugyo happened because of a power cut under profitability decreasing. It seemed that there many causes in this happening. And they are not simple but complex. Food security system is necessary under complexity. The production of milk for milk processing in Hokkaido has a function to defuse 'noise' of drinking milk market. The institution for milk processing supports the function. The food control system cut relationship between wheat producers and wheat processors to protect wheat producers. It causes a mismatch between supply and demand. Food systems are composed of resource producers, processors, distributors and consumers. Food systems composed of only one of them can not existence. An institution protecting only one of them causes some problems in the systems. Designers of institution of food systems did not recognize it.(3) Location fluctuations of food industries are analyzed. Accumulation power works on location fluctuations of food industries. Technologies result from emergence and make noise in food systems. The characters and utilizations for frozen food of some starch technologies are studied on.
