Analysis on The Mechanism for Influence of ICT Progress on Income Inequality in Economic Development

假设ICT的进步是技术实施水平的提高，我们构建了涉及实施水平和s型学习曲线的模型。结果如下。技术实施水平的学习率参数越高，稳态下的潜在生产率增长率越低。执行曲线的形状影响收入不平等。在理论分析的基础上，通过动态面板数据和多元回归分析等实证分析，我们证实了20世纪90年代以来全球收入不平等的扩大，信息通信技术的进步加剧了全球收入不平等。

Assuming that progress of ICT is regarded as increase of implementation level for technology, we construct the model where implementation level and S-shaped learning curve are involved. The results are the followings. The higher parameter for rate of learning as to implementation level of technology is, the lower growth rate of potential productivity at steady state is. A shape of implementation curve affects income inequality. In addition to the theoretical analysis, with empirical analysis such as dynamic panel data and multiple regression analysis, we confirm that worldwide income inequality has widened since 1990s and progress of ICT increases income inequality worldwide.
