Today, the Korean fisheries is undergoing significant hardships, both domestically and internationally. While declining amount of catch, ascending international oil prices and others pose a compelling challenge to the fishing sector, the ever strengthening influence of international institutions related to fisheries and international trade organizations also compel to bring about myriad of changes in the realm of fishery products. Against the backdrop, this study attempted to examine the fisheries catch, aquaculture, service, processing fields in terms of its rippling effect and of how the industry has been changed by analyzing the past and present through an input-output analysis. As for research methods, 168 items of the input-output tables in 2000, 2005, 2009, and 2010 were integrated to form and classify 32 sectors (28 basic sectors + catch, aquaculture, fishery service, processed fishery products) so as to generate production inducement coefficient, sensitivity coefficient, and impact coefficient. The analysis results revealed that : though the linkage effect of fishery industry was not very sizable, the impact coefficient of the processed fishery products was high; the consumption and investment coefficient sector among production inducement coefficient was on an upturn trend ; the export coefficient was tended to decline. In the future research, it is necessary to carry out a study based on the integration of detailed classification (404 sector) and a study and analysis of fishery industry by different regions through the inter-regional input-output tables. The fishery industry is one of the crucial industries in Korea. The fishery industry is not only important in its own right but also significant as it exerts influence over other industries. Therefore, it is required that there should be more investment and supports for the development of the fishery industry, and pay efforts to ensure that the investment and development could lead to mutual growth for both the fishery and other various industries.

국가간 지역간 물의 이동을 개념화하여 물 부족 현상을 정치경제학적 관점에서 접근하려는 가상수(virtual water) 연구가 국제적으로 진행되고 있다. 가상수를 양적 측면에서 산정하여 정확한 물 수지를 파악하면 수자원에 대한 국가의 계획과 전략 수립에 매우 유리한 여건이 조성된다. 우리나라의 국가계획인 수자원장기종합계획은 국가 간의 물 이동을 고려하지 않고 국내에서 발생하는 용수의 수요와 공급 측면만을 산정하고 있다. 그러나 현재에도 국내에서 소비하는 농산물과 축산물의 상당량은 수입에 의존하고 있으며, 향후 국제교역과 FTA의 확대 등으로 그 의존도는 더욱 증대될 것으로 추산된다. 따라서 국가 간 물 이동에 대한 양적 규모를 파악하여 국가전략을 수립하는 기초자료로 활용하기 위한 연구가 필요하다. 이에 본 연구에서는 산업연관분석법을 활용하여 국내 산업별(제조업, 서비스업) 가상수를 산정하여 국가 수자원계획 수립에 필요한 기초자료로서 제공하고자 한다. 산업연관분석(Inter-industry analysis)은 산업연관표를 바탕으로 산업 간의 상호 연관관계를 수량적으로 파악하는 방법이다. 이를 가상수 산정에 활용하여 직접수와 간접수를 포함한 물의 전체 사용량을 산정할 수 있다. 본 연구에서는 각 산업의 용수량을 총 생산량으로 나누어 물 강도($m^3$/원)를 계산하고, 생산유발계수와 최종수요를 곱하는 방식으로 산업별 가상수량을 산정하였다. 산업별 가상수 산정 결과는 경제총조사의 용수비와 산업연관표의 생산유발계수를 적용하였으며, 제2차 산업인 제조업 분야의 연간 가상수량은 60.4억 $m^3$, 제3차 산업인 서비스 분야의 가상수량은 연간 43.1억 $m^3$으로 분석하였다. 또한 향후 10년의 OECD 기술수준 제품군별 무역수지 전망을 고려한 결과, 기술수준 중 및 고 기술제품의 가상수 수출량이 2020년에는 2010년에 비해 약 3배 증가하는 것으로 산정하였다. 이와 같은 방법으로 산정된 산업별 가상수는 각 산업의 물 사용량을 추정하고 산업 전반의 수자원 활용도를 파악하는데 이용 가능하다. 더불어 국제 환경 및 기후변화가 반영된 가상수 시나리오 연구를 통해 장래 용수 수요변화예측 등 효과적인 물 관리 정책 수립에 기여할 수 있다.

Fishery industry is an important part of agricultural industry in coastal countries. The purpose of this study is to use the theory of industrial competitiveness for reference, use Analytic Hierarchy Process (AHP) and Delphi method to establish the evaluation index system, and analyze the fishery industry competitiveness of 11 coastal provinces in China. This study data came from China Fishery Statistical Yearbook 2020. The results show that Shandong Province is the most competitive province in fishery industry among the coastal provinces. The inter-provincial differences are great. Not only the resource endowment is the factor that affects the fishery industry competitiveness, but also the long-term profitability is too. The proportion of recreational fishery in the fishery economic output value has become one of the main indicators to measure the competitiveness of the fishery industry. The findings of this study suggest that all regions should adopt measures in accordance with local conditions, promote the integrated development of the fishery industry, enhance the added value of fishery products and enhance the competitiveness of fishery industry. The disadvantage of this study is that the fishery industry competitiveness of China's coastal provinces is only compared and analyzed. The future direction is to carry out a comparative study on the international competitiveness of fishery with other east Asian countries.

The main objective of this research is to examine the spillover effects of technological knowledge from IT industry to other industrial sectors and, based on empirical findings, to draw policy implications and suggest policy directions. To this end, we divide IT industry into IT equipment and IT service, assuming that these two sub-sectors are considerably different each other in terms of technology knowledge flow. Other industries are classified into 17 different sectors based on the KSIC of 1990. As the proxy measure of technological knowledge, the notion of R&D stock is employed. The Input/output(I/O) Table is used to define the inter-industrial flow pattern and to draw the knowledge flow matrix. As the research methodology, cost function model is employed to gauge the spillover effects of technological knowledge of IT industry. Based on the results of analysis, it is found that the economic impact of technology diffusion also exhibits a different pattern between IT equipment and IT service. The diffusion of IT equipment tends to show labor-substitution effect whereas IT service displays labor-creation effect. This fact should be considered in devising industry, education, and labor policy. The expectations from this research are as follows. First, the sectoral pattern, difference between IT equipment and service in particular, identified from this research may shed light on the sector-specific policy direction. It is emphasized that a sector-specific approach, rather than an aggregate approach, is relevant for formulating IT policy. Second, it is expected that the importance of technology diffusion programs and policy measures are recognized among policy makers in IT industry.

This study explored the current implementation status of corporate social responsibility (CSR) among textiles and apparel manufacturers and retailers in Korea, based on the Triple Bottom Line (TBL). We also investigated the provision of information related to CSR practices on the websites of companies. A quantitative content analysis was conducted to analyze the website disclosures of 61 listed companies categorized in the textiles, apparel, shoes, and luxury industry. Analysis was focused on the presence, accessibility, and the level of CSR website disclosure. Seven themes emerged by applying the constant comparison analysis. Using Scott's formula for pi, a high level of inter-coder reliability was achieved, ranging from 0.91 to 0.97. Regarding the three dimensions of CSR suggested in TBL, economic dimension was relatively more emphasized in the website disclosures of most companies, compared to social and environment dimensions. Website disclosures were further investigated, based on the product categories of each company. Limitations of this study and suggestions for future studies are discussed.
