Abstract
This study shows how to evaluate carve-out companies and how to develop the carve-out companies with parents companies continuously. Carve-out companies connect parents companies tightly, and their purpose of establishment are clear. Thus, benefits and their business plans are important. We considered the business plan by a figure with catalyst function as x axis and benefits as y axis. As a result, we found that the business plans after establishment of the companies were largely different from each other, by focusing on catalyst function or benefits. Furthermore, we found this figure showed the motibation and the trusts, and became evaluations of the carve-out compamies which aim for continuous development.
