This study has three main objects. First is to classify exporting firms in korean stock market as environmental management strategy. Second is to analyse the relationship between environmental management strategy and organizational resources(human resources, strategic proactiveness, and sharing of vision). Lastly, This study investigates whether or not more proactive environment management strategy affects environmental and economic performance. To accomplish these objects, it suggested literature reviews, research hypotheses, and proper research methodologies. The result is as follows: This study finds environmental management strategy groups that are reactive strategy, pollution prevention, and environmental leadership through cluster analysis. The suggested hypotheses are to verify through ANOVA. The findings are that more proactive environmental strategic firms have more organizational resources and higher environmental and economic performances.

본 연구는 자산 가격의 시가, 고가, 저가, 종가 정보를 이용하여 산출된 범위변동성과 이를 응용한 범위변동성 변화 즉, 기술적 범위변동성(Technical Range Volatility)의 분포특징을 이용하여 범위 변동성 변화의 예측가능성을 진단하고, 투자성과를 향상하는 데 이용할 수 있는지에 대한 여부를 분석하고자 하는 데서 출발하였다. 기존 문헌에서 해외시장을 대상으로 제시하고 있는 기술적 범 위변동성의 특징이 국내에도 나타나는지를 검증하고 투자성과에 응용할 경우 국제시장간에 어떠 한 유사점과 차이점을 보이는지 비교해 보았다. 자료는 2000년부터 2010년까지 미국, 일본, 한국의 주식시장의 주요지수인 S&P500, NIKKEI, KOSPI이며 한국시장내의 시장특징에 따른 비교를 위해 KOSDAQ시장을 추가 분석, 비교하였다. 그 결과 다음과 같은 사실을 발견하였다. 첫째, 기술적 범 위변동성의 특징은 한국시장에서도 유사하게 나타났으며 정규성 측면에 있어서 KOSPI시장이 더 두드러진 특징을 가지고 있었다. 둘째, 기술적 범위변동성의 수준을 분류하여 포트폴리오를 구성 할 경우 좌우 극단에 있는 포트폴리오의 1기간 후의 수익률이 평균적으로 높은 현상을 공통적으로 발견하였다. 다만, KOSDAQ 시장에서는 이러한 현상이 나타나지 않았다.

In the late 90’s of last century, E-commerce became the focus of research following its application in government, enterprises and many other fields. In this paper, we present a literature review of academic journal papers in China that was published on the subject between 1999 and 2012. We organize these studies into four main categories: technological issues, applications areas, support and implementation issues, and other issues. All of the papers in the review are allocated to the main and sub-categories based on their main focus. Our analysis of these papers provides useful insights on the anatomy of the E-commerce literature, and should aid the creation and accumulation of knowledge in this domain. A comprehensive list of references is also presented. It is hoped that the review will be a good resource for anyone who is interested in E-commerce research in China, and will help to stimulate further interest in this area. The implications for E-commerce researchers and practitioners and suggestions for future research areas are discussed.

This paper aims at analysing the technical efficiency and productivity of the 22 railroad lines using the SBM model and the Malmquist index. This paper utilizes data for the period 2004-2010. The SBM model uses two inputs to produce two outputs. The inputs consist of the number of staffs and non-labor cost and the outputs are the passenger revenue and man-kilometer. The result shows that most of lines not only have larger operational inefficiencies than scale ones, but are in a condition of increasing returns to scale. That indicates that it is more reasonable to increase the staffs as well as the investment in infrastructure rather than downsize the organization. The SBM/WINDOW analysis reveals that there is a very large efficiency gap among the DMUs. The efficiency is only greater than 0.8 in 3 of 22 lines, but that of 14 lines is below 0.4. The Malmquist productivity analysis indicates that both technological progression and higher technical efficiency enable the 9 lines including Kyungbu High Speed Line to increase their productivity. The other lines, however, suffer from lower productivity due to decrease of technical efficiency in spite of technological progression. The Kyungbu High Speed Line is shown to record the highest productivity increase of all lines.

The purpose of this paper is to analyze whether foreign investors prefer specific determinants in locating the investment and how the preference will actually differ across the regions, Busan and Kyeongnam. This study is distinguished from the previous studies. Firstly, it is based upon direct interview survey on the FDI determinants specifically in Pusan and Kyeongnam. Secondly, using non-parametric X2(Chi-square)tests, we test somewhat fundamental hypothesis, whether or not international firms do value differently among location factors (or determinants). Thirdly, the correlation has been tested using correlation coefficient Cramer V and chosen level of significance (probability P). Results show that there is significant difference between Pusan and Kyeongnam regions in perceptions of important factors such as infrastructures, markets, incentives, firm-level characteristics and also a significant difference of satisfaction with those factors. This means that international investors do prefer some factors to others and also that this preference differs across regions, Busan and Kyeongnam (including Ulsan) in our context. It indicates that to attract FDI inflow each region needs to develop region-specific FDI policy which is more likely to meet the specific needs of investors.

This paper seeks to search Korea’s strategic alternatives for the Korea-China-Japan FTA and Regional Comprehensive Economic Partnership (RCEP) negotiations after examining the changes and progress of the Korea, China and Japan and economic status and relationship of trade interdependence. From the viewpoint of three nations, Korea, China and Japan that need to pursue after Korea-China-Japan FTA and RCEP almost around the same time. First, it is recommended to pursue after the Korea-China-Japan FTA first and foremost, playing a leading role in case of the RCEP negotiations. Second, however, there is a need to prepare for the situation in which the three nation FTA is pursued at the RCEP level to prepare for the instance in which Korea-China-Japan FTA may be delayed. If the negotiation between Japan and China should be delayed compared to the agreements reached between Korea and China, and Korea and Japan, Korea has to sign the two-party FTA first, naturally. However, the Korean government needs to take on a more active role when it comes to the Korea-China-Japan FTA since Korea-China-Japan FTA is needed for the RCEP and since Korea-China-Japan FTA can contribute to the improvement of overall relationship at the regional level.
