First of all, data concerning the change in the industrial structure was collected. Though I inquired of various related groups regardless of the inside and outside Japan and examined material as far as I could do, I could not help judging, to my regret, that enough data (monthly data) does not exist to analyze changing the market structure in the statistically meaningful manner.Since the considerable time and the effort were used for the collection work of data, I had to put over theoretical model construction and concentrated only on the improvement of the simulation model. Up to now, I have introduced (1) a statistical physics technique that uses the transition probability to describe consumer behavior and (2) an algorithm of reinforcement learning to describe firm behavior.The following are regarded as future works :a)An important parameter concerning consumer's transition probability of changing firm to purchase goods is endogenized so as to be affected by the advertisement of firms.b)Learning processes of agents are introduced or refined so that they behave more intellectually (but in the boundedly rational manner).c)The branding strategy through an advertising investment etc. is incorporated.

首先，收集了有关工业结构变化的数据。尽管我询问各个相关小组，而不管日本内部和外部如何，并尽我所能检查材料，但我遗憾地判断了足够的数据（每月数据）来分析以统计上有意义的方式改变市场结构，而与统计学上有意义的方式更改市场结构。到目前为止，我介绍了（1）一种统计物理技术，该技术使用过渡概率描述消费者行为以及（2）强化学习以描述公司行为的算法。以下算法被视为未来的工作：a）关于消费者的过渡概率，使得企业的过渡概率是由他们介绍的，或者是由他们介绍的企业，或者介绍了企业，以至于他们介绍了企业，以至于他们介绍了这些企业，以至于构成了广告的范围。 c更智力上（但以有条理的方式）.c）通过广告投资等进行品牌策略。
