Understanding the Evolution of Network Structure of Market Using Large-Scale Multi-Agent Systems and Data Analysis

为了揭示有关市场结构动态的统计事实，《日本市场份额》（1972-2011年版）由矢野研究所进行的计算机化。由于输入工作的数量远远超出了最初的预期，数据输入大约在研究持续时间结束的同时完成。数据分析将是未来的任务。关于模型，虽然最初期望对现有模型进行改进，以便能够解释从数据分析中获得的统计事实，但由于数据分析的延迟，所做的只是对模型中的企业行为部分进行改进。

In order to discover the statistical facts about the dynamics of the market structure, "Market Share in Japan" (1972-2011 Eds.) by Yano Research Institute were computerized. Because the quantity of input work was far beyond the initial expectations, data entry has been completed at about the same time as the end of the study duration. Analysis of the data would be a future tasks. As for model, although it was initially expected to make improvements to the existing model to be able to explain the statistical facts obtained from the data analysis, because of the delay of data analysis, what was done was to make improvements to the part of the firm behavior of the model.
