We analyzed the effect of 6-month lagged number portability policy and introduction of common number among carriers on Korean mobile market. Our result shows that the policy change contributed to both the increase in number of mobile subscribers and decrease in dominant carrier's market share. We found that unified prefix among mobile operators is more effective than the lagged number portability policy. The carriers' profit, however, decreased a lot due to excessive marketing expenditure. We also estimated market shares of carriers up to year 2005 when full number portability policy is adopted. The results show that dominant carrier's monopolistic power will be recovered by the end of 2005 implying government's number policy itself cannot guarantee the effective competition in Korean mobile market.

This study derived implications regarding competition policy to establish a reasonable spectrum allocation draft of a 3.7 GHz spectrum band by indepth analysis of 5G spectrum auctions. The following general features were identified by examining auctions of three countries, including the United States, United Kingdom, and Denmark, were completed in 2021. First, securing the minimum bandwidth that is essential for service competition was guaranteed by applying the spectrum cap. Second, a continuous spectrum band was allocated to all mobile network operators. Third, certain requirements were implemented to encourage the expansion of 5G service coverage. The spectrum cap that was implemented in Korea during the most recent spectrum auction was ineffective regarding competition policy. Additionally, it is anticipated that the allocation of 3.7-4.0 GHz spectrum will considerably impact market competition because the continuity of spectrum band is different among mobile service operators. Therefore, it is time to discuss promoting the 5G service competition in Korea by revising related laws.

After the establishment of 'Staggers' Rail Legislation' in 1980, which established an atmosphere of free competition in rail freight transportation market, freight railway in America became larger and the proportion of freight railway in the market increased. In 2008, it took up 43% of the transportation market based on tonne/mile unit and the productivity of freight rail increased. On the other hand, in the case of Korea, the competing atmosphere is being set up under the influences of the renovation of the rail transportation industry in 2004. However, to make the rail transportation market more active and become more advanced, a lot of efforts are required to build a stronger foundation of free competition atmosphere. In this paper, we have deducted the political implications on the establishment of strengthened competition in Korean rail transportation industry from reviewing what kind of changes the rail transportation market in America went through and how it was developed. In this case, we have focused on the changes in industrial trend towards the restriction policy. Also influences of the deregulation policy after 1980 on the enhanced market efficiency were reviews.

본고는 산출물시장이 과점적이고 동질적 상품이 거래되어 기업들이 생산량 경쟁을 하고 배출권시장은 완전경쟁적일 경우, 기업이 지출하는 저감투자량의 적절성을 이론적으로 분석한다. 산출물시장이 완전경쟁적일 때와는 달리 저감투자는 직접적으로 배출비용을 줄이는 효과 이외에 다른 기업의 산출물을 줄이는 간접적 효과를 발생시킨다. 균형하에서의 저감투자량은 사회적으로 최적인 저감투자량에 비해 생산량 대비 과잉투자를 야기하여 투자배분을 왜곡한다. 본고는 또한 불완전경쟁시장이 배출권 거래제도하에서 발생시킬 수 있는 비효율성의 제반 요인들을 검토하고 정책적 시사점을 제시한다.

본고에서는 통신시장의 구조를 최대한 반영하면서 투명성, 객관성, 규제 비용, 정책목표 구현 등을 고려한 평가체계를 개발하여, 기존 평가 방법 대비 개선된 새로운 평가 기준을 만들었다. 그리고 국내 이동통신시장에 대해 새로운 평가기준을 적용하여 경쟁상황 평가를 시도하였다. 경쟁상황에 대한 1차 판단 결과 국내 이동통신시장은 지배적 사업자로의 지속적인 쏠림현상이 존재하여 유효경쟁 상태에 있지 않은 것으로 나타났다.

A Liner Conference can be defined as "a group of two or more vessel operating carriers which provide international liner services for the carriage of cargo on a particular route or routes within specific geographical limits and which has an agreement or arrangement within the framework of which they operate under uniform or common freight rates and any other agreed conditions with respect to the provisions of the liner services". This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. The repeal of the block exemption for liner conferences and the abolition of any special EC antitrust regime for the shipping industry marks an important step in European maritime competition policy. This article examines the origins and the rationale of the EC antitrust immunity granted so far th the shipping industry and explains the causes of this historic changes. The abolition of Regulation 4056/86 and of the EU commitment to the UN Code of Conduct marks an historical evolution in international maritime policy, which will have an influence far beyond the EU.

This research began by recognizing the development of telecommunication skill in a short period of time as one achievement of launching the national research and development (R&D) project for the diversification of telephone service and for the solution of telephone holdup rate. Under this concern, this research is focusing on searching the influential elements on successful outcome by analyzing the case of Time Division Exchange R&D Project carried out by Korea. Those variables for analyzing the case is limited to 7 definite variables, which are "willingness of policy making organization", "participation of manufacturers and buyers", "support from research and development group", "economy of operating methods and selection of machinery", "rate of technology transfer", "support from Fixer", and "quality management". Summarizing the result of analysis, in order to bring about technological innovation, knowledge creation activity leading to upward efficiency through competition and cooperation making a harmony should be done in one mechanism. I.e., launching an innovative policy should be done in an arena of competition and cooperation, where stability of implementing system is achieved, the entity of "Fixer" is an adequate operator, and competition and cooperation is efficiently managed, among where agreement on purpose and professional opinions are reflected.

영국의 이동통신시장은 2001년 8월 성인의 73%가 이동전화를 소유하고 있을 만큼 성장하였고, Vodafone, BTCellnet, One2One, Orange 등 4개 사에 의해 균형적인 경쟁이 전개되고 있다. 본 고에서는 영국에서 이동전화 사업자간 균형발전을 가져오고, 경쟁이 활성화된 배경을 정리하고 있다. 국내의 경우에 후발사업자와 선발사업자간 시장점유율 격차가 지속적으로 확대되고 있고, M&A에 의해 이용자의 사업자 선택권이 축소되고 있는 상황에서 영국 사례를 중심으로 경쟁이 활성화되기 위한 시사점을 살펴보고 있다.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discriminated. The purpose of this paper is to examine the competition policy theoretically, international background with issues, and discussion trend of global enterprise. By doing them, this paper suggests the responsive plan, future prospects, and policy directions for the competition policy by distribution service. There is not a statistically significant relationship between international diversification strategy and firm performance. However, we observed some tendency that the larger the firm size, the higher the firm performance, assuming the degree of international diversification or multinationality to be constant. However, the export productivity increase after 1~2 years, and there exits a clear evidence that the innovation investment increases a firm's export competitiveness as time goes on.
