    Flight Service Quality and Competition: Evidence from Regional Airports in Korea

    Joo Yeon Sun | 2020, 47(2) | pp.69~82 | number of Cited : 0
    Abstract PDF
    This study analyzes the effect of competition among carriers on short-haul domestic routes on departure flight delay rates at provincial airports. We construct panel data for each of two airports under a point-to-point network, covering the 2010–2018 period. The following two airports are compared: Daegu International Airport with night curfew restrictions imposed and Cheongju International Airport with no night curfew. The airport-by-airport estimation results from the ordinary least square and instrumental variable estimations are compared. Departure flight delay rates increase with competitive flight services, implying that competition among airline carriers would accelerate the delay in congested air traffic. For Daegu International Airport with curfew time restrictions, low-cost carriers’ timely flights would partly account for on-time performance improvement, but easing the night curfew from 8 hours to 5 hours would have no significant effect.

    Revisiting Neoclassical Realism in Understanding Variations in States’ Armaments: A Case of South Korea and Taiwan's Ballistic Missile Defense

    Bee Yun Jo | 2020, 47(2) | pp.83~100 | number of Cited : 1
    Abstract PDF
    Debating on Jeffrey W. Legro and Andrew Moravcsik’s critique on neoclassical realism, this article seeks to argue that the theory retains its own merits in understanding state behaviors in the international system. Paying particular attention to neoclassical realist literatures - including Randall L. Schweller’s elite cohesion/fragmentation, Jeffrey W. Taliaferro’s resource extractive state, and Steven E. Lobell’s discussions on foreign policy executives and societal elites - the article seeks to illustrate how the theory accounts for variations in states’ response to external security imperatives. Drawing parallels between neoclassical realism and literatures on preference formation and rationality in social science, this study argues that the foundational merit of neoclassical realism lies in advancing the realist paradigm towards what this study calls a model of “situated rationality” for capability aggregation. For empirical clarification, the last section of the article shows how the neoclassical realist framework can account for variations in South Korea and Taiwan’s armaments in the ballistic missile defense (BMD), despite similar security imperatives.

    What affects the User Sharing Degree of Public Transportation Apps in China? - A Comparative Study between Government App and Business App

    Guo Yuanyuan , Sun Yu | 2020, 47(2) | pp.101~131 | number of Cited : 1
    Abstract PDF
    In order to explore the factors influencing the user sharing degree of government apps in the field of public transportation, this study selected government app Beijing One Card and business app Bus Code (Beijing area) in the same field as the comparative analysis objects, and based on the network questionnaire survey and multiple regression analysis, explored the differences of factors influencing the user sharing degree of the two apps. It is found that system quality and platform promotion effect have a significant positive impact on the user sharing degree of two apps, while service quality has no effect on the user sharing degree of two apps. User preference affects user sharing degree of government app Beijing One Card, but has no effect on business app Bus Code (Beijing area). Since the downloads of Beijing One Card app is much higher than the downloads of Bus Code app (Beijing area), this paper believes that user preference determines that users are more inclined to choose government apps instead of business apps. In addition, government apps and business apps not only need to ensure the system quality and pay attention to the platform promotion effect, but also need to focus on the user’s preference and guide the direction of the user’s preference in a normal way, so as to improve the user sharing degree and expand the promotion scope of two kinds of apps.
