Study of the Change of the Commerce Structure in the City from the Point of View of the Regional Planning.

我们从两个方面分析了城市商业结构的变化。第一个方面是消费者意识结构分析，第二个方面是消费者行为分析。对于后者，我们应用了地理信息系统。我们特别注重区域比较和商业结构布局，旨在进行区域规划。研究结果总结如下：1.消费者意识结构分析近年来，随着商业环境的变化，消费者对商业结构的认识和行为发生了很大的变化。识别它们并不是一件容易的事情。我们用各种方法来分析这个问题。在意识结构分析中，AHP(层次分析法)是最有效的方法。此外，为了对居民进行分析，我们提出了语义度量方法和相对位置度量方法。我们检验了这些新方法的有效性。分析揭示了北海道与斋田在消费者意识结构上的差异。基于地理信息系统的消费者行为分析我们利用地理信息系统将消费者行为光盘和商业机构的分布情况描绘在地图上，然后在地图的基础上进行空间分析。我们还从地理数据库、商业机构数据库和购买行为数据库三个方面编制了一个综合数据库。有了这个数据库，我们就可以对食品、国内非耐用品、时尚服装、休闲耐用品、书籍和礼品等单个物品的购买行为差异进行分析。最后，我们明确了上述物品的购买行为的特点和差异。

We analyze the change of the commerce structure in the city from two aspects. The first aspect is consumer consciousness structure analysis, and the second aspect is the consumer behavior analysis. We apply GIS (Geographical Information System) for the latter. We especially pay attention to the area comparison as well as the distribution of the commerce structure, aiming at regional planning. Summary of the results are following :1. Consumer consciousness structure analysisConsciousness and behavior of the consumer toward commerce structure are greatly changing with the change of the commerce enviromnent in recent years. It is not an easy task to identify them. We analyze this issue by various methods. We perfotm analysis by AHP (Analytic Hierarchy Process) that is the most effective method in the consciousness structure analysis. Also, to perform analysis regarding the residents, we propose Semantics Measurement Approach and Relative Position Measurement Approach. We inspect validness of these new methods. The analysis reveals the difference in consumer consciousness structure between Hokkaido and Saitama.2. Consumer behavior analysis by GISWe depict the consumer behavior CD and the distribution of commercial institutions on a map by GIS.Then, we perform spatial analysis, basing on that map. We also compile a comprehensive database from geographic database, commercial institution database, and purchase behavior database. Wuth the database, we can carry out analysis about the difference in purchase behavior regarding individual items such as foods, domestic non-durable goods, fashionable clothes, recreational durable goods, books, and gifts. Finally, we make clear the characteristics of and differences in the purchase behavior regarding above-mentioned items.
