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

这个项目有三个主题。第一个是对粮食系统研究的复杂系统经济学的研究。第二部分是用复杂系统经济学研究粮食系统的结构变化过程。第三部分是用复杂系统经济学研究食物系统的空间变化，研究结果表明：（1）用复杂系统经济学来把握食物系统是必要的。特别是复合物理论中的“噪音”和“涌现”，对于研究食物系统具有重要意义。(2)分析了牛奶和牛奶加工以及小麦的食品系统。Yukijirusi nyugyo的食物中毒是因为利润下降而停电。看来，这其中有很多原因。它们不是简单的，而是复杂的。复杂性下的粮食安全保障体系是必要的。北海道牛奶加工用牛奶的生产具有缓和饮用牛奶市场“噪音”的功能。牛奶加工机构支持这一职能。粮食控制系统切断了小麦生产者和小麦加工者之间的关系，以保护小麦生产者。它造成了供需之间的不匹配。食物系统由资源生产者、加工者、分配者和消费者组成。仅由其中之一组成的食物系统是不可能存在的。如果一个机构只保护其中一个，就会在系统中造成一些问题。食品系统的设计者没有认识到这一点。(3)分析了食品工业的区位波动。集聚力对食品工业区位波动起作用。技术产生于涌现，并在食品系统中制造噪音。研究了几种淀粉工艺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.
