抄録

This paper measures the technical efficiency of joint public-private venture railways and private railways in Japan using the Stochastic Frontier Analysis.　We compare the following four groups using student’s t-tests: Group 1 is composed of rural railways operated by joint public-private ventures, Group 2 is composed of rural railways operated by the private sector, Group 3 is composed of urban rapid transit railways operated by joint public-private ventures, and Group 4 is composed of urban rapid transit railways operated by the private sector.　The results show that the null hypothesis of no difference between Group 1 and Group 2 in mean efficiency is not rejected, and the null hypothesis of no difference between Group 3 and Group 4 in mean efficiency is not rejected.
