Construction of metro transportation infra is a large-scale project requiring tremendous financial resources. This study suggests operation method to use for rapid transit line existing infra such as Gyeongbu line and spare line capacity following second phase KTX construction. Reviewing various constraints of metro rapid transit operation, we found that the conditions for metro rapid transit operation are already satisfied in Daegu area, just like the case of Gyeongbu line in Seoul Metro area. Also, the evaluation of the economic feasibility of metro rapid transit operation in Daegu area shows that S/C is about 2.4, which implies that there is sufficient economic feasibility. According to the result of sensitivity analysis, the project is economically feasible unless the passenger demand decreases 15% and construction costs increases more than 70%. SIC is evaluated large because the utilization of already exiting infra lowers the initial cost. As one of mass transportation system of large capacity, metro rapid transit can generate significant spillover effect: It will strengthen competitiveness of metro area by connecting cities within the area and by extending one-day life zone of the area, to say nothing of the benefit of improving traffic condition. The construction of metro rapid transit network is necessary for the mass transportation system of Yeongnam area as well as Daegu area, and it may work as a starting point for uniting Daegu and Gyeongbuk and strengthening regional competitiveness.

Purpose - The purpose of this paper is to analyze the productivity of major airports in Korea using Malmquist Productivity Index methodology and draw implications for airport operations and planning through comparison with existing research results. Also, The results of this study confirm the academic differences between productivity and efficiency. The results of this study provide policy assistance such as attracting, expanding and relocating airports, and eliciting academic implications. Design/Methodology/Approach - We analyzed the productivity of airports in Korea by applying the Malmquist Productivity Index Analysis Methodology among DEA methodologies. Not only individual airports, but also group-specific airports were analyzed. In addition, we compared the results of airport efficiency studies analyzed using efficiency analysis methods such as CCR/BCC. Findings - The larger the airport, the more productive it is. The productivity of the base airport (large) and the productivity of the general airport (medium) and the general airport (small) is inversely proportional. These results resulted in significant differences from existing efficiency studies. For example, an airport with very low efficiency can be measured very high in productivity with only a little performance. In general, however, highly efficient airports also tended to have high productivity, which means there is a correlation between efficiency and productivity. Research Implications - This study identified the relationship between efficiency and productivity by studying productivity aspects, not efficiency. As a result, productivity analysis as well as efficiency analysis should be accompanied for proper airport evaluation. As a result of this study will help not only the operation of the airport but also the planning and expansion of the airport.
