| Summary: | 碩士 === 國立交通大學 === 管理學院經營管理學程 === 104 === This study adopts the stochastic frontier analysis (SFA) to compute the disaggregate inputs efficiency of securities firms in Japan. The panel data set contains a total of 23 securities firms during 2010-2014. This study employs three inputs (stakeholder equity, operating expenses, and the number of employees) and a single output (total revenue). The major empirical findings are as follows: Securities firms with higher total assets have lower efficiency scores of stakeholder equity and operating expenses, but have better efficiency of employees. Older securities companies have worse efficiency than younger securities companies in the use of stakeholder equity, operating expenses, and employees. The higher TPX Index makes worse efficiency of operating expenses. In conclusion, Japanese securities firms have better efficiency of operating expenses, but still have a lot of room for improvement on the efficiency of stakeholder equity and employees.
