Global economy these days is characterized with an unlimited competition due to Globalization and Information Age. Expansion of E-business accelerates informationized and globalized society and also intensifies market competition. As a result, global economy gradually develops to knowledge-based economy, and Business Service Industry becomes essential to the production increase in the manufacturing industry as well as its high added value comes into the spotlight as one of rapidly growing business industry. Business Service Industry has not yet been academically established, however, it may be defined as the industry of which production is a mediating service in the production process rather than in the final consumption. The export of the manufacturing industry has traditionally played mainstream role in Korea where economic development has been centered on the manufacturing export. However, as with increasing emphasis on the role of service sector and highly developed industrial field in the national economy, not only the relationships between manufacturing industry and service industry becomes rapidly more involved, but also the importance of highly competitive service industry becomes emphasized in accordance with open global economy after WTO system takes off. Now it is time we come to the realization that service is in the center of national competitive power as a result of global door open in all service industry.

New retailers, especially giant retailers, so called "mart" or "discounter" which introduced around 1996, when Korea's domestic retail market was opened to the world, have brought big transitions. Consequently, new comers like discounters and CVS drove out department stores, mom & pops and traditional retailers. Literatures showed two reverse opinions for the giant retailers; rising consumers' benefit, or dropping small retailers' businesses. This study have conducted to find the situation of market concentration in retail market, and to learn the new market condition in it. According to the study, in 2005, CR3's of Korea's whole retail industry was counted 12.8%, and CR5 of that was 13.9%. CR3 of discount store business was 39%, department stores' 55%, and TV home shopping businesses' was 75%. In addition to those results, indices growing worse. So, we can say this industry already get into the oligopolistic industrial organization. Generally, under monopolistic or oligopolistic market structure, consumers' benefit may shrink and businesses' surplus profit may jump. So, it means, it's good time to turn government's policy for the retail industry in Korea to fair competition policy instead of development policy.

In an electricity market with imperfect competition, participants devise bidding plans and transaction strategies to maximize their own profits. The market price and the quantity are concerned with the operation reserve as well as the bidding system and demand curves in an electricity market. This paper presents a market model combined by an energy market and an operating reserve market. The competition of the generation producers in the combined market is formulated as a gaming of selecting bid parameters such as intersections and slopes in bid functions. The Nash Equilibrium (NE) is analyzed by using bi-level optimization; maximization of Social Welfare (SW) and maximization of the producers' profits.

본 연구는 최근 그 시장이 폭발적으로 성장하고 있는 소프트웨어 산업의 국제경쟁력의 현황과 대앙방안에 대한 연구이다. 인터넷 환경하에서 그 시장 규모와 중요성이 매우 커지고 있는 소프트웨어 산업에 있어 그 파급효과가 매우 크다는 점, 그 부가가치가 매우 크다는 점, 시장 선점 효과가 크다는 점 등은 기타 산업에서 볼 수 없는 매우 독특한 측면으로서 미국, 일본을 비롯한 다수의 관련 국가에서 이들 산업 분야에 대한 국제경쟁력 제고를 위한 다양한 노력이 시도되고 있으며, 우리나라 역시 다양한 시도가 되고 있다. 그러나, 이러한 노력이 국제경쟁력으로 이어지기 위해서서는 보다 단일화된 법적 제도적 지원이 전제가 된다고 판단된다. 또한, 이들 산업분야에 종사하는 인력은 여타 산업분야와 달리 매우 창의적이고 관련 분야의 고도의 지식을 갖춘 전문 인력을 필요로 하므로 장기적인 측면에서 소프트웨어 산업에서 국제경쟁력 확보의 관건은 해당 분야에서 필요로 하는 고급인력을 육성을 전제로 한다. 특히, 해당 업계의 의견수렴과 함께 세계적 동향과 궤를 같이하는 형태로의 인력 양성이 주목할 필요가 있다.

The Incheon International Amort Railroad (IIAR) is the railroad that connects Incheon International Airport, Gimpo Airport and Seoul Station. IIAR is now under construction, and it will be finished to Gimpo Amort by 2006, to Seoul Station by 2008. But IIAR is not only so late to start but also has no discussion about effective connecting methods to existing railroads and fine operation plan. Therefore, after IIAR opens, it is possible for IIAR to lose to limousine bus using highway. So, this paper proposes 4 effective connecting methods for IIAR - (1) Shuttle transport, (2) Short-distance connecting transport (Inside IIAR, Seoul Subway Line 9, 'Han-River line') (3) Mid-distance connecting transport (Jung-ang, Tae-baek, Young-dong line) (4) Long-distance connecting transport (Korean Train express (korean high speed railroad)) These methods can increase the connectivity of IIAR with existing railroads and the competition power of IIAR against highway.

This paper examined the factors affecting the implementation of information technology in Korean Global Logistics Companies. Nowadays, the spread of electronic commerce using internet demands a large changes doing business with company to company and give that company a change to recognize logistics. To support logistics activity, all kinds of companies are using the computer and are recognized that the efficient using of Cyber Logistics Information will mainly play a roll to strength the companies competition power. We gathered detailed data on our sample companies mainly from publicly available sources : Korea International Freight Forwarder Association (KIFFA), and companies' web sites. A structured questionnaire was used to collect information about: (1) the company (2) To investigate the factors of the three contexts described above on korean Global Logistics companies's electronic trade adoption and implementation. (3) Usage level of electronic logistics. Most of the approximately 70 questions enumerated in the questionnaire were open-ended, which was consistent with our primary objective of developing a conceptual framework that was informed by empirical evidence. This study suggests that top management support and influential power are main factors for the Korean Global Logistics Companies.

Purpose - The purpose of this study was to investigate market power of soybeans exported by the United States to Korea. Particularly, this paper considered dichotomous characteristics of genetically modified (GM) soybeans and non-GM soybeans and conducted empirical analysis of these two segregated soybean markets to understand key tenets of market power in international soybean trade. Design/methodology - The difference in market power between GM and non-GM soybeans was analyzed using Residual Demand Elasticity (RDE) and Residual Supply Elasticity (RSE) models over the period of 2008~2018. RDE and RSE models under an imperfect competition condition were used to estimate market margins and determine whether GM and non-GM exporters or importers exercised market power in the destination market. Findings - Empirical results suggested that the U.S. had a market power on both GM and non-GM soybean exports. GM exports had greater market power than non-GM exports (14% vs. 9%). By contrast, Korea showed an inability to grab market margin or exert market power in soybean imports. Both export supply by the U.S. and import demand by Korea were found to be more responsive to price changes of GM soybeans than to prices changes of non-GM soybeans. This might be due to a self-interested, profit-seeking strategy by the exporter and many concerned consumers regarding potential adverse effects of GMOs in the importing country. Originality/value - This paper fills the literature gap by exploiting market power in both GM and non-GM markets with explicit consideration of price correlations between GM and non-GM soybeans in Korea. A number of existing studies have provided evidence for market power broadly embedded in international commodity trade. However, studies focusing on Korean markets are limited. No study has explored the country's soybean trade. Furthermore, the majority of prior studies have almost exclusively focused on the market power from a standpoint of exporting countries without discussing importers' market structure. This paper also sought to understand potentially distinguished patterns of market power between GM and non-GM markets.

In 2005, the Korean government decided to postpone the introduction of competition up to 2009 in the power plant service industry. Thus, the purpose of this study is to analyze the efficiency changes and the determinants of international competitiveness of Korean power plant service industry by the comparison between before and after 2006. The sample used in the estimation of efficiency is six firms III Korean power plant service sector for the period of 2003~2008. According to the results, technical efficiency before 2006 (2003~2005) is 0.865 and that after 2005 (2006~2008) is 0.947, which implies that efficiency has been improved after the delay of introduction of competition. In addition, according to the analyses based on the diamond model of Porter using survey data, demand condition has been ranked first in the determinants of international competitiveness. The second and the third important conditions are government and input factor ones. Firm's strategy/structure/competitiveness condition is the most weak condition. Therefore, it would be necessary for firms to improve this condition for competitiveness.
