This study examines factors driving subscriber migration from traditional pay-TV to OTT services using the push-pull-mooring framework, analyzing switching behavior in the evolving media consumption landscape.
This paper examines the interaction between television-based home shopping and mobile applications in Korea's evolving digital market. Using monthly panel data from four major home shopping companies (2021-2023), we apply fixed-effects models to identify cross-channel effects. We find that higher TV viewership predicts increased mobile engagement, and that sustained app use supports user retention. TV and mobile function as sequential complements rather than substitutes — a 'reverse showrooming' pattern where television builds trust through live demonstrations while mobile apps provide transaction convenience.
We analyze platform power dynamics in Korea's home shopping industry, examining how market asymmetries shape competitive advantages and sustainability outcomes for television commerce platforms.
This paper evaluates operational efficiency of media companies using Data Envelopment Analysis and Malmquist productivity indices, providing insights into performance trends and competitive positioning in the media industry.
This study investigated the direct and indirect impacts of financial investment connectedness and Information and Communication Technology (ICT) on countries' intellectual property (IP) strategies. By utilizing the panel logit model on longitudinal country-level data, we found that countries' positions in the global financial investment network significantly affect their IP strategies.
This study aims to use ISM to identify the enablers affecting the acceptance of IoT services. For this purpose, this study conducted an ISM analysis and a MICMAC analysis, extracted the enablers from Internet of Things-An Action Plan for Europe published by the EU for the research, and conducted interviews and surveys.
This study analyzed the efficiency of global major mobile operators and the reason for their efficiency. For this purpose, the financial data of 96 operators in 40 OECD member countries were utilized.
An information system (IS) upgrade is an essential way to enhance the competitiveness of an organization. Specifically, the decision making processes surrounding IS upgrades is one of the most important parts of an organization's competitiveness in regard to business sustainability.
This study aims to examine Gov. 3.0 (E-government) efficiency of 42 central administrative agencies in Republic of Korea and to identify the critical factors which can have an influence on the improvement of Gov.
This study aims to comprehensively examine the adoption of smart home service. A new model combining VAM (Value-based Adoption Model) and TAM (Technical Acceptance Model) was developed and analysed with a set of variables from Unified Theory of Acceptance and Use of Technology and Elaboration Likelihood Model.
With the advancement of information and communications technologies, market related to Virtual Reality (VR) using mobile-based devices has been rapidly expanded. Global companies such as Google, Facebook, SONY and Samsung Electronics have competed for the preoccupancy in the virtual reality market by introducing products and services in the area of game, education, and tourism.
This study examines factors affecting adoption of mobile payment services in the Fintech industry, analyzing user acceptance patterns and behavioral intentions toward mobile financial technology services.
This paper identifies industrial characteristics of portal sites using stochastic frontier analysis and tobit regression, proposing that market share and appropriate fixed assets have positive impacts on portal site efficiency.
Terrestrial TV service operators have begun to represent an increasing share of content production in the media industry. However, despite its importance, there are relatively few studies about the efficiency of terrestrial TV operators.

This study analyzes the structural crisis in Korea's media industry financing and the unintended consequences of broadcasting reapproval investment requirements. Using panel fixed effects regression on 10 years of financial data (2015-2024) from major cable networks, we document a significant crowding-out effect: government broadcasting development fund contributions of KRW 43.1 billion are associated with investment reductions of KRW 73.3-164 billion, representing a 1.7-3.8 times crowding-out multiplier. Investment ratio requirements reduce ROI significantly, while the 44-year freeze on public broadcasting license fees and 43.5% collapse in broadcast advertising revenue compound the financing crisis. We propose a comprehensive reform roadmap including abolition of rigid investment mandates, revenue-linked alternatives, and license fee normalization.

This study examines the relationship between organizations' compliance with digital policy requirements and their performance outcomes, assessing whether and how compliance translates into measurable organizational gains.
This paper investigates how digital input intensity and a firm's structural position within production networks jointly shape integration into global value chains across the creative industries. Combining network analysis with panel estimation, the study assesses whether digitalization reconfigures which firms capture value as creative production becomes increasingly cross-border and platform-mediated, and how network centrality conditions the returns to digital adoption.
Using daily investor-type trading flows around KOSPI 200 and KOSDAQ 150 reconstitutions (2016-2025), this paper identifies who supplies liquidity to the mechanical demand created by index funds. Around rebalancing dates, index investment trusts execute large mechanical trades that are absorbed primarily by foreign investors, who accumulate ahead of the event and distribute on the rebalancing day. The investor-type decomposition reveals foreign investors as the marginal liquidity provider behind the documented pre-event price run-up and its partial reversal, evidence that the price effects of index reconstitution are intermediated by a specific class of investors rather than the market at large.
This paper asks when OTT regulation achieves its intended effects, arguing that institutional context conditions the impact of regulatory frameworks. Using cross-national variation in regulatory regimes, it estimates the heterogeneous effects of regulatory interventions on the market performance of a global OTT provider, showing that the same regulatory instrument can produce divergent outcomes depending on the surrounding institutional environment.
Even after smartphone saturation, the composition of use continues to shift. This study conceptualizes the platform-driven move toward passive smartphone use as 'platform-driven drift' and examines its links to media displacement and affective well-being. Using 2010-2024 time-diary panel data from the Korea Media Panel Survey with fixed-effects models and Callaway-Sant'Anna difference-in-differences, it documents structural passivization in which passive use rises far faster than active use within the same device, associated declines in television viewing, active PC use, and print consumption, and a link between passive use and higher negative affect that turns positive among older adults.
This study analyzes how global streaming platforms reshape local content ecosystems through the case of Netflix's collaborations with Korean production firms. Situated in debates on cultural globalization, it examines how a global distributor's investment and commissioning practices interact with local production capacity, creative autonomy, and the industrial structure of a national content sector.
