In this study, I first inductively constructed a theoretical framework for rating evaluation based on the rating criteria of rating agencies active in Japan. I then conducted a textual analysis of rating releases published by rating agencies to clarify what financial information is emphasized in actual ratings. This provided clues for the selection of explanatory variables when constructing a creditworthiness evaluation model. In addition, this study clarified the theoretical foundations of textual analysis that had previously been unclear.
