The demand for the study about the pollution haven activities under increasing return to scale is increasing since the trade theory under increasing return to scale has been developed. In this paper, based on Davis (1998)'s argument about home market effect, pollution haven activities under increasing return to scale is developed. The result shows that pollution haven effect can be identified with the high trade barriers. When the trade barriers are lowered, both pollution haven effect of heavy polluted industries and migration of low polluted industries are mixed together. Even the behavior under pollution haven hypothesis and that of pollution haven effects are co-existed. Therefore, to keep both environmental protection and continuous economic development, the local government of the region with high environment preservation value encourages the productivity increase of the environmental technique.

This study analyzed annual final sample data from 159 companies based on firms selected as economic justice companies by Economic Justice Institute in Citizens' Coalition for Economic Justice in South Korea according to interest variables from 2005 until 2011. Analyzed results are as follows. First, higher scores in soundness and corporate social activities among CSR items suggested that corporate credit rating upgraded. This indicates that credit rating institutions give a good evaluation on their social activities and reflect them in credit rating assessment. However, environmental protection satisfaction and corporate credit rating showed the opposite results. Second, high objectivity and contribution to the economic development as well as supervision by giant auditors had substantial effects on higher corporate credit rating. In contrast, high soundness and supervision by giant auditors reduced corporate credit rating. Based on this outcome, it is estimated that there is a discriminatory response among CSR activities in terms of credit rating evaluation conducted by credit rating institution.

As the spatial structure of a region is evolving into a decentralized multi-nucli model, networked connection among cities in a region is emerging as an important issue to strengthen regional competitiveness. This paper focused on the limitation of current new town planning criteria which just suggest a uniform standard for economic self-sufficiency by new-town size, without representing the network characteristics of new town. If a new town is planned as a economic strongpoint within a region, it needs to secure appropriate industrial functions. This study classified the characteristics of new towns by network analysis and reviewed the economic self-sufficiency criteria by new town types. Using various network connectedness indices, the 1st and 2nd round new towns in the capital region were analyzed, and land-use distribution of new-towns in other countries were also examined comparatively. The network characteristics of new towns are classified as three types: mono-nucleus, distributed center, and dependent. Based on this classification, planning criteria for self-sufficiency were compared among 6 new towns. This study provides implications for the amendment of "the sustainable new town planning criteria" or the revision of development plans.

In the past, the United States has been engaged in large-scale urban development projects as a tool for urban regeneration to revitalize distressed urban areas. On the other hand, large-scale urban development projects have been stalled or discontinued globally since the 2008 economic crisis. Despite this, the Hudson Yard development, which is the subject of this study, has resumed smoothly due to the characteristics of its development structure and rational negotiation process. Most domestic developments depend on the economic circumstances, and the problems that are exposed in a privately led development are repeated; the Yongsan International Business District Development is a representative failure case. This study examined the characteristics of the business structure and the nature of the negotiation process in the Hudson Yard development project in New York City.

This study analyzes the technological level of Korean waste-to-energy(WTE) firms and its determinants by using a multiple logistic regression analysis based on a survey. As the results of analysis, the technological level of Korean WTE firms has been positively influenced by the firm size, R&D expenditures, R&D manpower, but negatively influenced by the competition in domestic market. Also there is no significant effect of the economy of scale. The policy implications of this study are as follows; First, the system in which stakeholders coevolve should be set up to prevent excessive market competition from having a bad effect on the technological level of Korean WTE firms. Second, it is needed to make an effort to achieve the economy of scale by increasing an output and decreasing cost in WTE firms.

국내의 저수지 비상대처계획수립은 저수용량 100만$m^3$이상의 중 대규모의 댐 및 저수지를 대상으로 수립되고 있다. 반면, 전국 14,208개의 시 군 구 지자체관리 저수지 가운데 80% 이상을 차지하고 있는 30만$m^3$ 미만의 중 소규모 저수지에 대해서는 피해규모의 정량화 방안이 체계적으로 구축되어 있지 못한 실정이다. 이에 본 연구는 중 소규모 농업용 저수지의 붕괴로 인하여 하류부에서 발생하는 피해를 산정하고, 잠재적인 피해액을 예측할 수 있는 홍수피해액 산정방법을 연구하고 인명 및 재산피해를 추정하는 기법을 연구하였다. 홍수피해액 산정에 대한 연구는 1970년대에 치수경제성 분석의 필요성이 대두되면서 원단위법(1993, 건설부, 하천시설기준), 회귀분석법(2001, 건설교통부, 치수사업 경제성분석 개선방안 연구), 다차원법(2004, 건설교통부, 치수사업 경제성분석 연구 방법) 순으로 발전되어 왔다. 원단위법과 회귀분석법의 문제점을 보완하기 위하여 다차원법이 제시되었지만 사용하는 자료가 방대하고 실제 가용성이 제한적인 자료를 포함하고 있어서 적용성이 떨어지는 단점을 가지고 있다. 본 연구에서는 중 소규모의 농업용 저수지 붕괴로 인한 홍수범람시의 피해액산정을 위하여 기존의 원단위법과 다차원법의 장점을 취하여 침수피해추정곡선법(IDEM : Inundation Damage Estimation Method)을 적용하였다. 인명손실액, 이재민피해손실액, 건물피해액, 건물내용물 피해액, 농작물 피해액, 농경지피해액, 공공시설물 피해액으로 구분하고 현재 제공되는 통계자료와 GIS 기법을 이용하여 대상 저수지인 창리저수지의 붕괴에 따른 소규모 범람구역의 침수심별 홍수피해액을 산정 후 침수심-피해액 곡선을 작성하였다. 창리저수지의 경우 저수지 붕괴시 0.4m의 침수심부터 제내지의 침수피해가 발생함을 알 수 있었으며, 침수심-피해액 곡선을 이용하여 침수심별 피해규모를 예상할 수 있었다. 향후 다양한 저수지에 적용성을 검토하여 국내 중 소규모 농업용 저수지 붕괴에 따른 홍수피해액 산정에 이용될 수 있을 것으로 판단된다.

The purpose of this study is to analyze traffic volume between the Korean container ports located at the west coast and northern Chinese ports and then the distribution trend of container between Korea and China. The findings of the study are as follows. First, Container traffic between western Korean ports and northern Chinese ports has been increasing due to an increasing trade volume between both countries and geographical accessibility. Second, Seoul and neighboring area tend to use the trade route between the western ports and northern Chinese because of lower logistics costs and time-saved advantage compared to another ports. Third, the growth of the western ports did depend mainly on the northern China oriented growth. Such a fact could leads to the overlapping investment in port development in Korea and another intense competition among national ports to attract cargoes and liners. Therefore, port development policy considering the characteristics and function of national ports have to be established. and also alternatives and strategies for improving the competitive edge of small and medium sized shipping lines against the opening of shipping market have to be worked out.

As the industrial complexes that led the national economic growth of Korea become older, it is necessary to prepare countermeasures to improve the competitiveness of these industrial complexes. The purpose of this study is to analyze the determinants of the competitiveness of old industrial complexes in Korea. It was found that the characteristics of the industrial structures, new companies, the working and production environments, and the regions in which these complexes exist all affect their competitiveness, but the effects differ according to the size of the complex. In particular, for large-scale complexes, the central government should play a role in their restructuring to improve their competitiveness. On the other hand, local governments' management of new companies is more important for small-scale old industrial complexes. These results provide implications with regard to the effective management of old industrial complexes.

Saemangeum Development is the largest national project in South Korea, which has been developed for an agricultural, economic and tourist area for 30 years from 1987. In order to convert power sources that used to depend on nuclear and thermal power to eco-friendly for carbon reduction, the government plans to construct a 2.1GW floating photovoltaic project by investing 4.6 trillion won, as a public-private project. For success of the Saemangeum floating photovoltaic project, economic feasibility should be checked. This study defined the factors (construction cost, electricity selling price, power generation and maintenance cost) that give a effect to the volatility of the floating photovoltaic payoffs, and analyzed the volatility of payoffs during 20 years operation period. NPV and option value of the project were calculated by applying an option to abandon. According to NPV analysis, it is determined that projects are difficult to invest. But this project has economic feasibility through real options analysis. This study is expected to help decision-makers in the economic analysis of floating photovoltaic projects by using the real options analysis.

식품관련 질병의 증가, 식품산업의 거대한 성장과 제품, 생산과정의 다양성 등으로 식품안전성 문제가 대두됨에 따라 전 세계적으로 식품위생 시스템에 기초한HACCP을 확대 적용하고 있는 추세이다. HACCP은 식품의 안전성 확보를 위하여 식품의 생산단계에서 발생 가능한 위해 요소를 사전에 관리하는 과학적 관리시스템이다. 국내의 90% 이상을 차지하고 있는 중소규모 식품산업체는 현실여건상 HACCP을 적용할 수 없는 실정이다. 따라서 본 연구는 중소규모 식품산업체에서 효율적으로 적용할 수 있는 HACCP의 적용방안을 제시하였다. 미국, 일본, 캐나다, EU, 한국의 HACCP 현황 자료를 수집하였으며, 미국, 일본, 캐나다, 영국의 중 소규모 식품산업체를 위한 지원방안을 조사하였다. 국외의 경우기업체의 크기 등에 따라 차등화 된 유예기간을 적용하거나, HACCP 적용을 위해 재정상의 보조금 지급, 교육, training, 의사소통 등으로 식품산업체에 HASCP적용을 지원하고 있었다. 설문 방문조사를 통해 국내 중소규모 식품산업체에서의 실태 및 HACCP 적용의 문제점을 조사하였다. 재정상의 어려움, 전문인력의 부족, 경영자의 위생인식 부족이 가장 큰 문제점으로 파악되었다. 이를 토대로 유예기간 지정으로 그 문제점을 개선하는 한시적 간소화방안을 제시하였다. 식품의 안전성은 기업의 크기와 상관 있는 것이 아니라 operation과 관련된 것이기 때문에 중소규모 식품산업체도 대기업과 같은 식품위생기준을 적용하여 관리하여야한다. 따라서 HACCP 적용의 일정 기간의 유예기간를 두고 경제적 지원과 지도 교육, HASCP 원칙 중기록 및 검증의 단순화, 전문 인력의 양성 등을 통해 그 기간 후에는 중소규모 식품산업체에 HACCP 적용을 용이토록 하는 안을 제시하였다.
