The Korean domestic media environment is seeing a rapid and dynamic change. Consumer media behavior is shifting from TV to smartphones, and from traditional media, such as terrestrial TV and cable, to intelligent Internet-based media, such as OTT channels and social media. This affects the profit structure of each media company and the competition among them, furthermore, the competitiveness of media services. In this regard, we propose a domestic UHD activation plan after evaluating the competitiveness of each media based on the analysis of the changes in the domestic media environment and the status of UHD services.

석왕헌,박추환 한국경영과학회 2017 經營 科學 Vol.34 No.4

This study used an absolute and conditional convergence model to analyze the effects of information and communication infrastructure on income convergence and decision making in 16 domestic provinces and metro-cities. The analysis of IT(Information & Technology) infrastructures is focused on telecommunication equipment investment, Internet penetration rate, and computer penetration rate. As a result, it is analyzed that there is some positive relationship between the construction of ICT infrastructure and the rate of income convergence in the region. Specifically, the largest contributor to regional convergence was the gross value added in the region (with a convergence rate of up to 8.2%). The adverse impacts on convergence speed were telecom equipment investment, and internet penetration rate and computer penetration rate had a positive effect on convergence rate (0.3% p, 0.2% p increase respectively). Finally, analysis of determinants of regional incomes showed that telecommunication equipment investment showed a negative relationship with regional economic growth, while internet penetration rate and computer penetration rate showed positive (+) relationship. It is expected that this study will be used as a basic data of regional communication policy since it can grasp the mutual influence between telecommunication equipment investment and regional economic growth.

메타버스와 NFT 비즈니스 모델현황 및 고려사항

석왕헌,W.H. Seok 한국전자통신연구원 2023 전자통신동향분석 Vol.38 No.2

The combination between metaverse and non-fungible token (NFT), which opens up new opportunities for the media industry, raised expectations for a new economic system and business model. Of course, last year, various institutions and researchers continuously introduce representative metaverse services and business strategies such as Roblox, Fortnite, and ZEPETO. However, as 2022 progresses, the reaction to the metaverse is tepid than expected. Search volume on Google has been continuously decreasing. Furthermore, skepticism, regarded as one of the special phenomena caused by the coronavirus disease 2019 pandemic, is expanding since December 2021. Nevertheless, analysis or contemplation of a new business model related to the metaverse, which is still ongoing, is essential for those who must prepare for the future. The reason is that even if without being activated now, advanced preparation can help when various problems arise. In this study, we look at the metaverse and NFT biz models and estimate a picture of the future. In other words, the social and economic problems that may arise when the business model is expanded are summarized, and technical and policy measures are derived as solutions.

석왕헌,Seok, W.H. 한국전자통신연구원 2021 전자통신동향분석 Vol.36 No.4

Recently, discussions on Metaverse, which represents the transcendent world, have been dominant for some time. Cases related to the Metaverse are introduced through various media and are continuously attracting attention as the next generation of the Internet. This study reviews the business model and the ecosystem overview, focusing on service cases related to the Metaverse. The widely used business models include content production and sales, media brokerage fee, and marketing fee. The Metaverse ecosystem is formed around games, with major players in game production, authoring tool & support SW, intelligent cloud service, and game platform expected to lead the market. Results show that a strategy to secure the leadership of the Metaverse, such as the business model expansion conditions, a strategy to foster a game-oriented Metaverse ecosystem, and technology development for the realization of the ultra-realistic Metaverse, is necessary.

방송산업의 진입, 소유 및 겸영규제에 대한 문제점과 해외사례 분석

석왕헌(Seok, Wang-Hun),박추환(Park, Chu-Hwan) 영남대학교 산경연구소 2009 영상저널 Vol.2 No.1

본 연구는 방통융합이라는 새로운 환경속에서 방송산업규제의 핵심이라 할 수 있는 진입규제, 소유 및 겸영규제에 대한 문제점을 확인하고, 해외사례 분석을 통해 규제틀의 방향성에 대해 제시하고자 한다. 먼저 문제점에 대해 살펴보면 우리나라는 크게 수탁이론과 미디어균형발전이라는 개념틀 속에서 규제가 이루어져오고 있으며, 이러한 점은 지상파방송의 공공성을 제외하더라도 종합유선방송, 방송채널사용사업, 그리고 위성방송산업에 경쟁력을 가지기 어려운 환경을 제공한다는 점이다. 이는 수탁이론이나 미디어균형발전개념 틀이 여전히 수직적 시장획정을 통한 규제를 가하고 있기 때문으로 판단된다. 이에 반해 해외 사례를 분석해본 결과 진입규제와 관련해서 각 방송사업영역에 대한 규제의 완화하고 융합법 체계 속에서 네트워크와 콘텐츠에 따라 진입규제를 이원화하여 운용하려는 조류를 형성하고 있다. 또한 소유 및 겸영규제는 완화함으로써 소유의 집중에 대해 어느 정도 인정하고, 그에 따른 부정적 효과를 상쇄시키기 위해 여론의 다양성을 확보할 수 있는 방법을 제시하고 있는 것으로 나타났다. 따라서 미디어 환경의 재편에 따른 방송관련 정책은 동종 및 이종매체들 간의 결합 혹은 제휴에 대한 기존의 규제가 새로운 방통융합시장환경에 맞도록 조정하는 가에 대한 중요한 문제로 본다면 우리나라의 경우 규제체계의 수정이 필요할 것으로 판단된다. This paper analyses the problems of entry regulation, ownership and combining the management regulation for the broadcasting industry, which are the core regulations parts under the changing environment of the merge with broadcasting and telecommunication. First of all, the problems that occur from the core regulations are that the regulation of the Korea"s broadcasting has maintained the theroy of trust and the direction of the media development, which didn"t sustain the competitiveness of the fields in the total line broadcasting, the broadcasting channel business, and the satellite broadcasting except the ground frequency broadcasting"s publicity. This means that the theory of thrust and the media development restricted those parts by imposing the regulation with the vertical market fix. However, the major oversea"s countries have decreased the degree of regulation for the broadcasting industry so as to have the competitiveness with separating the network and entry barrier regulation, and have recognized the ownership and the merge of broadcasting by allowing the concentration of ownership.

석왕헌 ( Wanghun Seok ),고순주 ( Sunju Kho ),박추환 ( Chuhwan Park ) 한국지역개발학회 2015 韓國地域開發學會誌 Vol.27 No.3

This study conducts an analysis on the determinants of the total factor productivity with telecommunication facilities investments by using random coefficient model for the 16 metropolitan and provincial regions in Korea. The estimation coefficients with including the telecommunication facilities investment in production function as a production factor show that total telecommunication investment, fixed telecommunication investment, and the mobile telecommunication investment have statistically significant effects on the output. In addition, the results of the determinants for the total factor productivity which is characterized as an dependent variable indicates that capital and labor per capita have a negative effect on the total factor productivity, however, three different types of telecommunication investment, energy consumption per capita, and research and development per capita have a positive relationship with total factor productivity. We except from this results that telecommunication investment based on the different regional production structure can increase the total factor productivity and can be used as a policy guidelines.

This study conducts an analysis that find out the regional economic convergence phenomenon among 16 domestic regions by using absolute and conditional convergence model. Especially for the conditional convergence model, telecommunication CAPEX(Capital expenditure) has divided into various types. The data used in this research is unbalanced, depending on the period of each statistical data from 16 domestic regions, but formed a panel data using statistical data from 1995 to 2012 in general. In addition, this research analyzes the absolute and conditional convergence phenomenon through random effect model. To begin with, the conditional convergence model in the research has progressed with the objective of searching out the effect of physical capital, human capital, and telecommunication CAPEX on the convergence of regional economic through Barro(1989)`s empirical model. Besides, in order to understand a various relationship between telecommunication CAPEX and regional economic growth, telecommunication CAPEX consists of two types(wire, wireless) and technologies(3th generation, 4th generation). As a result, this research shows a fact that the absolute and conditional convergence phenomenon of regional economic growth exists among 16 domestic areas. Secondly, in case of telecommunication CAPEX, wireless(1.4%) CAPEX of the convergence rate is faster than wire(0.2%) CAPEX. Also, the convergence rate applied for periods of 4th Generation(1%) wireless telecommunications CAPEX is faster than 3th Generation(0.5%). Thirdly, in the analysis of determination factor, telecommunication CAPEX, irrespective of wire or wireless, has positive impact on regional economic growth by helping a capital accumulation in region. However, since wireless CAPEX has a negative relationship associated with average rate of regional economic growth, better planned telecommunication policy for regional economic growth is needed. Meanwhile, this research has a limitation that cannot compose a perfect telecommunication CAPEX stock by using telecommunication and facilities construction data. Nevertheless, this research enable us to not only understand the relationship between telecommunication CAPEX and regional economic growth, but also provides fundamental data for a telecommunication policy.

방송시장에서 주요 사업자 간 기관운영의 상대적 효율성 분석: DEA분석을 중심으로

석왕헌 ( Wang Hun Seok ),박추환 ( Chu Hwan Park ),박광만 ( Kwang Man Park ),김성민 ( Sung Min Kim ) 한국응용경제학회 2010 응용경제 Vol.12 No.1

본 논문은 방송시장의 주요 영역인 지상파, 종합유선, 방송채널사용사업에서 각 영역별 주요사업자를 대상으로 DEA기법을 이용하여 기관운영의 상대적 효율성을 분석하였다. 분석결과 먼저 지상파방송의 경우 공영과 민영 모두 효율성이 평균적으로 하락함을 보이고 있고, 지역별 공영이 민영에 비해 효율적인 지역이 많은 것으로 나타났다. 그러나 서울, 광주의 경우 오히려 민영이 공영에 비해 더욱 효율적으로 운영되는 것으로 나타났다. 그리고 공영방송 비효율성의 원인은 대부분 순수기술비효율성이 원인이었고, 민영방송은 규모의 비효율성에 기인하는 것으로 나타났다. 두 번째로 종합유선방송의 경우 티브로드(태광)와 C&M이 CJ에 비해 최적효율성을 달성하고 있는 것으로 나타났다. 마지막으로 방송채널사용사업 부문에서는 복수MPP 사업자인 CJ와 온미디어 모두 최적효율성을 달성하고 있으며, 투자 대비 이윤발생이 효율적으로 이루어지는 것으로 나타나고 있다. This paper analyzes the relative efficiency of ground broadcasting, service operator, and program provider in broadcast industries by using DEA(data envelopment analysis) methodology. As a result, in case of the ground broadcasting, both the public and private business` efficiency are decreased averagely; moreover, a regional public business has higher efficiency than private businesses, whereas, in case of the seoul and Kwangju city, private businesses operate more efficiently than other sector. On the other hand, the main cause of the public sector`s inefficiency is mainly associated with a pure technical inefficiency, while a private sector`s inefficiency is primarily related to scale inefficiency. What is more, both T-broad and C&M company show that those company are accomplished with optimal efficiency to contrast with CJ company. Lastly, CJ and On-media company as multiple program provider have been acquired with optimal efficiency; those company show that their profits over investment efficiently get achieved.
