최근 지속적인 전력 수요 증가와 이에 따른 사회적 비용 및 갈등 해결을 위한 방안으로 수요자원 거래시장(Demand Response Market)의 활성화가 크게 대두되고 있다. 국내의 경우 2014년부터 수요자원 거래시장을 운영 중이나 대규모 수요자원 거래에 집중하고 있다. 하지만, 전력 소비 비중의 증가, 큰 감축 유동성, 항상 활용 가능, 사회 인식 개선 등의 면에서 소규모 전력 소비자의 시장 참여는 성공적인 수요자원 거래시장 운영의 핵심적 요소로 볼 수 있다. 이 논문은 2016년 여름 스마트폰 어플리케이션을 활용하여 5,000명 이상의 소규모 전력 소비자를 대상으로 한 인센티브 기반(incentive-based) 수요반응(Demand Response) 프로그램의 실제 시범운영 결과를 분석하고 그 효과를 검증하며, 이를 통하여 소규모 전력 소비자 대상 수요자원 거래시장의 가능성을 제시한다.

Purpose: This study aims to utilize geographic data to analyze how various retail formats of large-scale stores around the traditional market affect the performance of the traditional market in Seoul, Korea. Research design, data, and methodology: The two types of catchment areas were demarcated (circle of 1km radius and Thiessen polygon) for each traditional market, and the large-scale stores located within each catchment area were identified for 153 traditional markets in Seoul, Korea. Additionally, multiple regression analysis was utilized. Results: The results revealed that the influence on the performance of the traditional markets were different depending on the retail format of the large-scale stores. Large discount stores were found to have a negative effect on the sales and the visitors of traditional markets, whereas complex shopping malls and department stores had a positive effect on the traditional markets. Conclusions: As a result of the differences in the retail format such as product categories and leisure functions, the impact of some large-scale stores on the traditional market may have a greater agglomeration effect than the consumer churn effect. Therefore, it is suggested that in the regulation of these large-scale stores, the differences in retail format should be considered for the future.

Purpose - This paper attempts to identify the problems and limitations of a market maintenance project conducted according to the 「Special Act for the Development of Traditional Markets and Shopping Street」 and to present a revised direction for the special law and lay the groundwork for market maintenance projects to be promoted smoothly. Research design, data, and methodology - The revised direction for the legislation and the proposal were written based on an investigation of the problems and the legal system, and proposed measures for market maintenance operation and system improvements to derive the improvements needed for market maintenance projects. Results - A market maintenance project has been conducted as a means to reinvigorate traditional markets that are economically depressed, and to revive the local economy. It was largely conducted in the form of reconstruction and redevelopment and represents the interests of landowners and merchants. Thus, it is most likely to contribute to the gradual disappearance of traditional markets. First, as part of a market maintenance project, many companies are building multipurpose buildings or high-rise residential buildings to increase profits. In these high-rise buildings, they can raise rents, which may not be affordable for some existing small businesses. To solve such problems, the large-scale store registration requirement needs to be relaxed or abolished once the market maintenance project is completed. If the large-scale store registration requirement is to be abolished, the term 'large retail store' should be changed in the 「Special Act for the Development of Traditional Markets and Shopping Street」. After registration, the Small and Medium Business Administration should train merchants, offer consultations, and support events, to the extent that the existing traditional market management modernization project permits, and further continue to manage and support its ongoing activities. However, unless large-scale store registration is abolished, adding an exception clause in the special law to relax large-scale store registration criteria, and permitting changes to building use is another option. At the end of a market maintenance project, empty stores should be purchased by the Small and Medium Business Administration, and local government, etc., at the actual construction cost, to utilize them as public rental shopping areas, which in turn may be re-utilized as a temporary market for another market maintenance project. The second problem in market maintenance projects is merchant-protection. Currently, the special law prescribes that a temporary market be created for merchants to conduct business during the rental period of a market maintenance project. Conclusions - In reality, a market maintenance project is conducted usually in big metropolitan cities with 500,000 residents or more. The main building type created under these projects is a multipurpose building. For this reason, it is very difficult to secure a location for a temporary market in the surrounding area of such a project. To solve this problem, this study suggests 'public rental shopping areas' as mentioned above.

This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).

Rapid spread of intermittent renewable energy has amplified the instability and uncertainty of power systems. The Korea Power Exchange (KPX) promoted efficient management by opening the power brokerage market in 2019. By combining small-scale intermittent renewable energy with a flexible facility through the power brokerage market, the KPX aims to develop a virtual power plant system that will allow the conversion of existing intermittent renewable energy into collective power plants. However, the participation rate of renewable power owners in the power brokerage market is relatively low because other markets such as the small solar power contract market or the Korea Electric Power Corporation power purchase agreement are more profitable. In this study, we used a choice experiment to determine the attributes affecting the participation rate in the power brokerage market for 113 renewable power owners and estimate the value of the power brokerage market. According to the estimation results, a low smart meter installation cost, low profit variations, long contract periods, and few clearances increased the probability of participation. Moreover, the average value of the power brokerage market was estimated to be 2.63 million KRW per power owner.

최근까지 국내 유통산업 성장의 주도적인 역할을 담당해 온 대형할인마트 시장이 점차 업체들간의 치열한 출점경쟁에 따른 내수시장의 포화상태 및 수명주기단축 등 성장의 한계에 다다르게 되었다. 이러한 국내시장의 한계에 따라 대형할인마트들은 생존과 성장을 위해 해외 신규매장 진출, 혹은 해외 유통체인 인수, 그리고 단순 글로벌 출점뿐만 아니라 글로벌 소싱전략 등을 통한 다양한 해외시장 진출전략과 마케팅 전략을 시도하고 있는 상황이다. 기존에는 유통선진국의 글로벌 기업들이 상대적으로 후진국인 아시아지역 국가들에 선도적인 지위를 차지하며 진출을 해왔지만 1980년대 후반 이후 아시아 경제가 급성장하게 되면서 일본과 같은 동아시아 유통기업들의 아시아시장 진출이 시도되기 시작하였다. 중국을 필두로 해서 경제발전 속도에 비해 유통서비스산업 등이 상대적으로 선진화되지 못한 아시아시장은 서구선진국 글로벌 유통기업뿐만 아니라 일본, 한국 등 동아시아 국가들이 내수시장의 한계를 극복하기 위한 탈출구로써 활발하게 진출이 행해지고 있는 시장이다. 이미 많은 유통기업들이 중국 등 아시아시장 진출과정에서 다양한 이유로 인해 성공과 실패를 경험하였다. 유통산업, 특히 대형할인마트의 아시아시장 진출에 있어서 상대적으로 후발국가라고 할 수 있는 우리나라의 경우, 해외진출의 원인과 과정이 우리와 유사한 일본 대형할인마트의 해외진출 사례와 전략을 살펴보고 이를 통해 우리나라 대형할인마트의 성공적인 해외 진출을 위한 전략적 시사점을 찾아보고자 하였다.

Control systems are used to limit structural lateral deflections during large external loads such as winds and earthquakes. Most recently, the semi-active control approach has grown in popularity due to inexpensive control devices that consume little power. As a result, recently designed control systems have employed many semi-active control devices for the control of a structure. In the future, it is envisioned that structural control systems will be large-scale systems defined by high actuation and sensor densities. Decentralized control approaches have been used to control large-scale systems that are too complex for a traditional centralized approach, such as linear quadratic regulation (LQR). This paper describes the derivation of energy market-based control (EMBC), a decentralized approach that models the structural control system as a competitive marketplace. The interaction of free-market buyers and sellers result in an optimal allocation of limited control system resources such as control energy. The Kajima-Shizuoka Building and a 20-story benchmark structure are selected as illustrative examples to be used for comparison of the EMBC and centralized LQR approaches.

Globalization of R&D activities of multinational firms is becoming important in compared with the past, because of increasing globalization of world economy. So, every country tries to attract foreign investment including R&D activities. In this paper, effects of several factors, which determine the scale of foreign subsidiary's R&D activities in local market, are analyzed. Through the review of previous literature, I found that three groups of determinant factors. The first one is the factor which is related to characteristics of local market, such as competitive situation of local market, accessability to research institutions, etc. The second group is the factor which is related to relationship between foreign subsidiary and its mother company. The dominant factors of this group are operation strategy of foreign subsidiary, competitiveness of mother firm, and equity structure of foreign subsidiary. Finally the characteristics of industry affect to the scale of foreign subsidiary's R&D activities. Among these factors, 6 factors are chosen to investigate empirically. For the empirical investigation, 107 foreign subsidiaries among KOITA(Korea Industrial Technology Association)'s list are chosen. Each subsidiary has more than 50% of foreign equity and implement R&D activities in Korea. The results show that sales volume of foreign subsidiary is dominant influencing factor in determining scale of R&D activities in Korean market. And also I found that currently established firms are implementing more R&D activities than old established firms. This is quite interesting finding. However, R&D activities of foreign subsidiary are not vitalized in Korean market. It probably means that Korean government and Korean business partners have to make effort to enhance foreign firms/ R&D activities, because it could contribute technological and economic development of Korean market.

The main reason for the increase in cross-border mergers and acquisitions in developed and emerging countries is globalization and growing economic interdependence across countries. The state of the economy has a significant impact on whether cross-border mergers and acquisitions are encouraged or discouraged by international strategic capital market changes. This study empirically evaluates the influence of determinants of economic development on the scale effect of Cross Border M&As separately on emerging and developed nations as a research gap. We first separated the small and large scale firms based on companies' worth and used panel regression to analyze the impact of GDP, employment rate, and market capitalization on cross-border merger & acquisition deals over the period of 2008-2018. Results indicate that GDP and market capitalization have a positive effect on CBM&A, whereas employment rate has a negative effect on CBM&A deals in large-scale firms of both emerging and developed countries. This study results offer the implication for the potential investors and policymakers to strategically analyze the implementation of cross-border mergers & acquisitions.
