서울과 부산의 준공영제 시내버스 효율성 비교연구

Abstract

The efficiency of Quasi-Public Bus Operating System in Seoul and Busan was analyzed by DEA model. The three-year change in efficiency of the two cities from 2015 to 2017 analyzes what are the positive impacts of implementing this period. The two cities, Seoul and Busan, were analyzed to see if they had higher efficiency indices and what were the inputs that had a positive effect on transportation revenue. To do this, Tobit regression analysis was performed. First, the number of operations that had a positive effect on the transportation income was the “operational number” in both Seoul and Busan.  Second, Seoul is more efficient than Busan by 0.189 CRS and 0.034 VRS.  Third, in the question of whether policy changes could affect the efficiency index fluctuations, the value of 2017 was lower than 2015, so the effect of policy did not have a positive effect on efficiency. In Busan, the value of 2017 is lower than that of 2015, so the effect of the policy did not have a positive effect on efficiency. The lack of a positive effect on these efficiencies is a lack of feedback on how to implement the policy and in the field. In terms of financial support, Seoul increased steadily from 2016 to 2017, while Busan increased in 2016 and slightly decreased in 2017. In Busan, there was a proportional change in the amount of financial support and efficiency, and in Seoul, although the difference was somewhat different, the decrease in efficiency from 2017 to 2015 was in proportion to the increase in the amount of financial support. In light of this, it can be seen that a decrease in operational efficiency leads to a proportionate increase in financial support. Therefore, selective expansion of the size of inputs should be considered to increase efficiency.
