The static status and dynamic trend of the market structure in the international wheat trade market are empirically analyzed. The export inequality level empirically proved to be high compared to import inequality level. And such states have been maintained since 2001 until 2014. Although the concentration level of export side seems to be easing, the international wheat market remains imperfect competitive market. Moreover, overall imperfect competitive status over 2002-2014 has been worsened compared to 2001 level. The main reasons are that the overall trends of the imports concentration is reduced more than those of the export concentration level.

From middle of 90's, SCM had emphasized the importance of connection of all companies which participate to a market, and outsourcing has emphasizes the slim structure of companies for pursing cost reduction and service improvement. But outsourcing as '2-1=1' and integration as '1+1=2' not adapt to the advanced market but return to the former state. Besides, it is impossible of subcontractors and logistics companies to execute these strategies which are win-win strategy and outsourcing. So many logistics companies have sharp competition in price recently. Therefore logistics companies have increased the need for a profitable business model and strategy. This paper researches the limitations of logistics market and redefines the role of logistics through the evolution of logistics. Also this paper proposes new role(Logister) and structure(Velcro structure) for not maker-oriented logistics but market-oriented logistics. The introductory case study will help to understand 2 terms(logister and velcro structure).

본 연구에서는 방산시장의 시장구조와 경쟁현황을 측정하기 위한 방법 및 방위산업과 방산시장의 특징을 살펴보고, 연도별 주요 방산업체 매출액을 바탕으로 시장점유율 및 상위 기업집중률, 허핀달-허쉬만 지수를 적용하여 시장구조와 경쟁현황을 분석해 봄으로써 국내 방산시장이 독과점구조에서 벗어나 경쟁지향적 시장 형태로 변화하도록 개선방안을 제안하고자 한다. 이를 위해 방산시장과 유사한 형태의 시장들을 비교·분석하였으며, 그 결과를 바탕으로 방산업체의 다양한 공급능력 구비를 위한 정부의 지원정책 추진, 정부 주도하 방산제품의 공급 시기, 규모, 기간을 고려한 기업 선정, 군 소요에 대한 정보 제공 등의 개선사항을 제안하였다. 이는 정부가 정책을 추진하는데 있어 근본적인 시장구조 개선 및 산업 차원의 정책개발을 통해 공정하고 원칙에 맞는 방산시장을 조성하여 기업 운영의 효율성을 추구하기 위함에 있다.

In this paper, I tried to analyze the relationship between the market structure of teleommunicatin industry and market performance using Economides and Lehr's results considering composite goods methods. And I took three policy scenarios into account. First, government tires to implement the policy which divides the integrated monopoly into network operator and service provider, then invite competition to service part. Second, government tries to implement the policy which invite the competition to service part only. Third, government tries to implement the policy which invite the competition to integrated duopoly. I gained the best result in the third scenario. So we can conclude that Parallel vertical integration is the best market structure. I also specially checked the relationship between the market structure and service quality. I gained the best service quality in the third scenario. So we can conclude that Parallel Vertical Integration is also the best market structure with regard to the service quality.

경쟁구조와 산업성과 간의 관계에 대한 연구는 경쟁정책 분야의 핵심 주제이다. 특히 통신 산업과 같이 독과점적 시장을 형성할 가능성이 큰 산업에서는 독점력이 산업성과(후생)에 미치는 영향과 효과에 대해 보다 심도 있는 연구가 필요하다. 즉 소수 사업자로 시장이 집중되면, 독과점에 의한 초과이윤의 개연성이 높아지고 이는 사회후생 증대에 부정적이기 때문이다. 이러한 배경 하에 본 연구는 이동통신 산업의 시장구조(시장 지배력 형태)와 사회후생 성과(요금 인하)의 관계를 국제비교를 통해 실증하고자한다. 구체적으로, OECD 주요 21개국을 대상으로 국내시장의 경쟁구조 변화양상과 사회후생 성과수준을 비교하며, 시장지배력 수준에 따른 평균 소매요금 인하율의 차이를 실증한다. 분석결과는 국내시장의 경쟁상황 및 시장구조는 글로벌 추세와 상당한 괴리가 있음을 보여준다. 또한 독점시장으로 인식되는 1위 사업자의 점유율(CR1>50)이 높은 시장에서는 소비자 후생을 증진시키는 요금인하가 더디게 이루어지는 것으로 나타났다. 이러한 결과는 시장지배력이 강한 독점적 사업자의 독점력 완화가 요금인하, 후생증대에 중요한 요소임을 보여주며, 경쟁정책의 방향이 시장집중도(HHI)의 개선뿐 아니라 지배적 사업자의 독점력 완화에도 초점을 두어야 함을 시사한다.

The purpose of this article is to suggest what is the desirable direction of economic relationship between Korea and China. The economic relationship between countries is based on how the present network is. As the economic relationship between countries grows, the network between countries will expand. In the past, the economic relationship between Korea and China is cooperative one from the viewpoint of international division of labor. Korean industries was focused on the value-added and mid-advanced technology products, while Chinese was focused on the labor-intensive products. As the China's economy grows for more than thirty years, there is a great change in China's economic policies and environment. China's industry structure is moving from the labor-intensive industry to technology-oriented industry. China's exports to the global market is increasing very fast, and China's domestic market is also growing. The change in Chinese industries' structure bring about severe competition in the global market. The expanding China's domestic market is also good opportunity as the new market in the world. The change in China's industrial structure needs for Korea to establish the 'New Network" between two countries. Korea has to grab the new opportunities in the China's domestic market and find new cooperative network with the products and industries.

산업조직론적 차원에서 국내외 종합유선방송(SO)사업 중심으로 연구가 이루어졌으며, 프로그램공급업(PP)에 대한 연구도 일부 있었다. 그러나 PP의 시장 구조, 시장 행위, 시장 성과간의 관계를 종합적으로 분석한 논문은 없었다. 이 연구는 케이블TV 시장 내에서 PP를 시장 구조, 시장 행위, 시장 성과간의 관계를 종합적이고 역동적인 측면에서 살펴보았다. 산업조직론적 시각에서 국내 40개 상업 PP를 대상으로 첫째, 시장구조와 시장행위, 둘째, 시장행위와 시장성과, 셋째, 시장구조와 시장성과간에 어떤 영향을 미치는지에 대해 분석하였다. 분석 결과 : 첫째, 구조 행위와의 관계에서 수평결합이 가격 및 규모에 영향을 미쳤다. 둘째, 행위 성과 측면에서는 가격이 가입자당 매출액 및 시청율에 영향을 미쳤다. 수신료 의존도의 경우 가입자당 매출액에 부적으로 영향을 미쳤다. 셋째, 구조 성과와의 관계에서 수평결합은 시청율에 영향을 미쳤고, 제품 차별화는 가입자당 매출액에 부적으로 영향을 미쳤다. 매출원가는 매출액영업이익률에 부적으로 영향을 미쳤다.

This paper studied the factors that influence on RN staffing level in the 43 Specialized general hospitals. Market structure was analysed using the monopsony model. The degree of competition was estimated by Herfindal Index and market was defined as Great medical zone. As the result of the estimation, in the more competitive hospital market hospitals employed the higher level of RN staffing, so monopsony model was supported. Hospitals with above 1001bed employed more RN than hospitals with below 700bed did. Hospital type, hospital union and the number of medical doctor did not affect the level of RN staffing. There was positive correlation between the level of RN staffing and the number of nurse's aid. The structure of RN market in Specified general hospitals was proved monopsony market, it seems that government regulation will be needed to improve social efficiency and equity.

Building a target capital structure is one of the most important decisions in corporate financial management. The purpose of this article is to identify the determinants of capital structure and adjustment mechanism toward the target leverage. The partial adjustment model was applied on a sample of 306 non-financial companies listed on Vietnam stock exchange market during the period of 2008-2017. By the fixed effect model estimation method, the research results have discovered the factors of growth opportunities, firm size, tangible fixed assets and firm's unique characteristics have a positive effect on the target capital structure of enterprises. Besides, profitability and dividend payment have a negative effect on the target capital structure of enterprises. Accordingly, the research results show that the average adjustment speed toward target leverage of the firms is 90.03%. Research results also demonstrate firms have higher or lower debt ratio than the target debt ratio, capital surplus or capital deficit also have an impact on the adjustment rate toward the target capital structure. The research results are consistent with the Dynamic Trade-off Theory. From this result, this article has provided policy implications for non-financial companies listed on Vietnam's stock market in building a reasonable target capital structure according to operating timeline to maximize enterprise value.
