This study is an empirical investigation of faculty compensation at major private universities. The scope of the research was limited to direct compensation such as base salary, allowances, and bonuses, while excluding indirect benefits such as pensions and medical insurance. The methodology was divided into two parts—compensation structure and compensation level—employing both literature review and empirical investigation. The empirical investigation involved a comparative analysis of compensation regulations (including salary scales and allowance tables) across major private universities nationwide, item by item. Additionally, a case study of a specific university was conducted using a questionnaire survey to analyze faculty opinions. The findings revealed that while the compensation structures across universities were largely similar, the forms of base salary differed, falling into three types: rank-based step salary, single step salary, and reverse single step salary. Regarding compensation levels, disparities existed across universities, which were ranked on an annual salary basis. Problems in the compensation regulations of the case university were identified, and improvement measures were proposed.
