대형 백화점들의 다점포화전략, 할인점의 증가, 무점포업태의 성장 등으로 지방 백화점 고객들이 점포 전환을 용이하게 할 수 있는 유통환경이 조성되고 있다. 따라서 그동안 제한된 경쟁상황에서 영업활동을 해 온 지방 백화점들은 고객전환행동에 대한 폭넓은 이해를 필요로 하고 있다. 본 연구는 지방 독점백화점 고객들의 전환행동 특성파악을 위해 선행연구를 검토한 후 유통환경의 급격한 변화속에서 고객들의 전환행동 특성을 불만즉요인, 전환장벽, 전환의도, 고객육특성(쇼핑향유성향, 다양성추구성향, 경쟁에의 노출정도, 인구통계특성)의 관계를 중심으로 파악해 보았다. 그 결과 불만족요인 평가는 고객의 특성(쇼핑향유성향, 경쟁에의 노출정도)에 따라 차이가 있으며, 전환장벽 인식은 고객의 특성(경쟁에의 노출정도, 인구통계특성) 및 불만족요인 평가에 따라 차이가 있고 예상경쟁자로의 전환의도는 고객의 특성(쇼핑향유성향, 경쟁에의 노출정도, 인구통계특성) 및 전환장벽 인식에 따라 차이가 있는 것으로 나타났다. 따라서 경쟁자의 시장진입을 눈앞에 두고 있는 지방 독점백화점의 전환관리는 고객특성 파악과 고객불만족을 감소시키려는 노력을 중심으로 이루어져야 할 것으로 보인다.

How health care providers compete and how competition among them affects their behavior are crucial questions in theory and health policy. In ordinary markets, competition improves social welfare, However in health care markets facing uncertainty and information asymmetry, competition can take the form of wasteful quality competition and result in cost increase. The purpose of this study is to examine the characteristics of hospital service markets and examine the impact of hospital competition on hospital behavior, more specifically hospital cost and the size of personnel. Based on patient discharge data of 2002 by the Ministry of Health and Welfare and Korea Institute for Health and Social Affairs, and health insurance EDI claims data of 2002, this study measures the degree of competition in the inpatient service market of hospitals, using variable radius method and Herfindahl index. The result of the study shows that the hospital service market consists of on average 3.13 government administrative units(shi, gun, or gu). Compared with hospitals, general or general specialized hospitals cover larger markets and operate in more competitive markets. Nearly 60% of patients use hospitals, which are not located in their government administrative units, meaning that market definition based on variable radius is better than the conventional method of market definition based on government administrative units. The results of multivariate analysis show that competition is not associated with high cost index of hospitals. But hospitals in more competitive markets employ larger(more intensive) input of personnel per 100 beds, implying that hospital competition in Korea can have the form of quality and cost-increasing competition.

Purpose: Corporate social responsibility is a self-regulating business model that helps a firm be socially accountable to the public. By practicing corporate social responsibility, firms can be conscious of the kind of impact they are having on all aspects of society, including economic, social, and environmental. Corporate social responsibility activities are not directly linked to increasing corporate performance and corporate value, but rather involve spending expenses. Based on these facts, this study verifies whether the effects of corporate social responsibility activities differ depending on the firm's situation. Research design, data and methodology: This study analyzed the effect of market competition on corporate social responsibility activities using logistic regression analysis on listed companies in the KOSPI and KOSDAQ for fiscal years 2014 through 2016. In this study, market competition was measured using the Herfindahl-Herschman Index(HHI). Higher HHI value can be interpreted as a lower degree of market competition. We also measured corporate social responsibility activities using the KEJI Index published by the Korea Economic Justice Institute (KEJI). If a firm-year is included in the top 200 companies of the KEJI Index, it is classified as a good corporate social responsibility activity firm. Results: We find that companies in less competitive market were not included in the KEJI Index. This result indicates that firms in the market with lower market competition perform less corporate social responsibility activities that incur costs. An additional analysis showed that there was a significant negative relationship between the market competition and the corporate social responsibility activity scores published by the KEJI Index. These result adds robustness to the result of the hypothesis that firms that have a monopolistic place in the market practice passive corporate social responsibility activities. Conclusions: The results show that managers of a firm in the lower market competition have a lower incentive to use limited resources for projects that are not directly related to revenue. The results of this study imply that corporate social responsibility activities vary according to the position of the business. Therefore, this study suggests that market investors should consider the degree of competition in the market when they evaluate corporate social responsibility activities.

Purpose - This paper analyzes how Research and Development (R&D) cartelization and Research Joint Ventures (RJV) affect firms that engage in Cournot competition in their product market using a model in which the Home and Foreign firm produce differentiated products and export their total output to a third country's market. Design/Methodology - In a two-stage game, research expenditures incurred in the first stage improve product quality and are subject to various degrees of spillovers. We consider four different scenarios. Findings - In a symmetric equilibrium we observe the following: (i) an RJV that cooperates in R&D decision yields the highest R&D expenditure. However, the scenario which yields the lowest expenditure depends on the extent of differentiation between the goods and the degree of spillovers; (ii) RJV cartelization yields the highest product quality, output, and consumer surplus in the third country; however, the lowest is produced by R&D competition if spillovers are strong and by R&D cartelization if spillovers are weak; and (iii) each firm's profit is at its minimum in R&D competition and its maximum in RJV cartelization. Furthermore, if spillovers are strong, the profit of each firm in R&D cartelization is greater than that in RJV competition, and vice versa. Originality/value - By analyzing product innovation in international markets, we can find similarities and differences between process R&D and product R&D in international markets.

This study analyzed the effect of the factors of introducing information technology(organizational and environmental characteristics) on non-financial performance. As detailed variables of each characteristic, the technical support/task force, users' IT capability, and education/training were used for the organizational characteristics while the degree of competition, external pressure, and uncertainty of environment were used for the environmental characteristics. In the results of the analysis, such factors like technical support/task force, users' IT capability, and education/training of the organizational characteristics had significant influence on non-financial performance. Also, factors such as degree of competition, external pressure, and uncertainty of environment of the environmental characteristics had significant influence on non-financial performance.

The long-existed licence system which has acted as one of the strong barriers to entry in the ocean shipping market in Korea is supposed to repeal in the near future. As a result, competition among the different sizes of firms which are operating under regional shield by means of the licence will be intensified. The main objective of this paper is to estimate the degree of economies of scale and economies of density for various firm sizes. For the successful estimation of economies scale and economies of density, translog cost models are developed and estimated through SURE technique which was suggested by Zeller (1963). The major findings are as follows ; All shipping firms in the sample exhibit economies of scale and density. Even small size shipping firms under licence system, they show substantial economies of scale contrary to the wide-known idea that small-size firms are subject to diseconomies of scale. For the ranked firm sizes according to owned deadweight tons, the degree of economies of scale decreases as the firm sizes are larger and larger. The degree of economies of density moderately declines from the smallest to the firm size of 30-60 thousand deadweight tons and sharply rise thereafter. And the large shipping firms with over half-million deadweight tons exhibit high economies density compared to other sizes of firm. If follows that the larger firms have great advantage in competition if the licence system is abolished.

일반건설업과 전문건설업의 겸업제한을 폐지하여 폐쇄적 시장구조를 개선하자는 주장이 제기되고 있다. 일반건설업과 전문건설업의 겸업 허용은 경제적 측면에서 불 때 양자의 시장을 통합하는 결과를 초래하여 한국의 시공시장에 일대 변화를 초래할 가능성이 높다. 그러나 건설시공 시장의 구조에 대한 실증적 분석에 기초한 논의는 부족한 실정이다. 이에 본 연구는 건설산업 정책과 관련한 합리적 논의의 기초를 제공하기 위하여 전문건설업 시장의 구조를 개방성과 경쟁성의 관점에서 실증적으로 분석하는 것을 목적으로 하며, 문헌연구 및 시장구조에 대한 자료를 이용한 시계열분석을 이용하여 수행되었다. 본 연구의 결과를 요약하면 다음과 같다. 전문건설 시장의 진입규제는 지속적으로 완화되어 일반건설업과 비교하여 상대적으로 개방성은 높은 것으로 평가된다. 전문건설 시장의 진입규제 완화에 따른 업체수 증가로 인해 전문건설업 시장의 성장률 대비 업체당 계약실적 증가율은 상대적으로 낮으며, 또한 하도급계약 낙찰율이 하락하고 있어 경쟁성은 높은 것으로 평가된다.

The study suggests an answer to the question of what determines category diversification of Internet portals in Korea. First, as external factors, competition intensity and market growth are hypothesized to have influence on the degree of category diversification. Second, an internal factor, user loyalty to portals, is hypothesized to influence negatively category diversification. The study performed empirical analysis based on weekly portal-specific panel data of eighteen internet portals in Korea during the period between 2001 and 2004. The result shows that category diversification increases as competition intensity increases, and that category diversification decreases as user loyalty increases. There was no effect of market-level growth rate on category diversification.
