| dc.description.abstract | In recent years, Along with the breakthrough of Machine Learning technology in the artificial intelligence, this technology is widely used in various fields. In this study, we analyze the change of social welfare and profits when the manufacturer imports the Machine Learning technology, and suppose that there are high quality and low quality manufacturers in the first period, and the high quality manufacturer use Machine Learning technology to improve the quality of their products in the first period, and convey the effect of Machine Learning to the second period through the intertemporal model. And find the variables through the backward induction in the second period, and use the variables to find the first period variables, finally, observe the relationship between the variables and the Machine Learning effect. And we found that when the manufacturer imports the Machine Learning technology, social welfare will increase when the Machine Learning effect increase. For high quality manufacturer, profits will increase when the Machine Learning effect increase, but for low quality manufacturer, profits will decrease when the Machine Learning effect increase. | en_US |
