Field of Study

Commercial Science

“Commercial Science” is synonymous with “marketing” in a broad sense. This discipline is systematically sub-divided into “macromarketing” and “micromarketing.” In the subfield of micromarketing, Japan’s distribution network, the structure of trades between Japan and the United States, or the EU transaction system, for example, will be investigated. The subfield also includes analyses of how macro phenomena are influenced by various factors that are characterized by micro and macro elements. This provides implications for policy makers regarding institutional designs for what is ideal at the macro level. Further to this, the History of Marketing Thought and Methodologies of Commercial Science, which do not fall under the categories of either micro or macro, are categorized as macromarketing issues for the sake of convenience. On the other hand, in the subfield of micromarketing, the focus will be on the aggregation at the micro level, for example, the behavior of manufacturers, wholesalers, retailers, and consumers. As in the case of the aforementioned macromarketing studies, various methods for description, explanation and management are being explored.
