Comparison of Modularization in the Information Service Industry and Construction of the Productivity Analysis Model

在本研究中，为了分析标准化和模块化对国际分工组织所处的信息服务业生产率的贡献，构建了将开放式创新作为变量的生产率分析模型。由此证明，自21世纪初以来，日本信息服务业的劳动生产率增长率随着剩余总和的下降而下降。

In this research, in order to analyze the contribution of the standardization and modularization to the productivity of the information service industry, in which international division-of-work organization is following, the productivity analysis model which puts the open innovation into the variable is constructed. In consequence, it is establish by proof that the labor productivity growth rate of information service industry in Japan has come down by the degradation of the residual sum, since the 2000s.
