The economic crisis in North Korea has reduced its capacity to invest in the energy industries. The country is going through a vicious cycle of decreased investment in the energy industries and reduced energy production. This suggests that the energy industries would come to the top priority of investment once the economy improves. This paper calculated the economic ripple effect of the investment on North and South Korean economies based on the assumption that 390 billion won was invested in the construction of a natural gas combined-cycle power plant in Gaesong Industrial Complex. In order to analyze the economic ripple effect of the investment on North Korean economy, we constructed the inter-industry relation table of North Korea for year 2014 and used the input-output model. The ripple effect of the investment in the natural gas industry turned out to be 1.012 billion dollars. In order to analyze the effect of the investment on South Korean economy, we constructed the inter-industry relation table of South Korea for year 2013 and used the demand-driven model for inter-industry analysis. As a result, production, added-value and employment inducement coefficients of the investment in the natural gas industry were calculated as 2.02073, 0.62697 and 8.99409 respectively.

The government is trying to expanding the manufacture and utilization of solid refuse fuel (SRF) facilities in order to mitigate greenhouse gases reducing and eco-friendly waste-to-energy recovery. In this regard, this study attempts to look into the economic effects of expanding the manufacture and utilization of SRF facilities by applying an inter-industry analysis using a 2014 input-output table. Specifically, by applying the demand-driven model presents the results for the production-inducing effect, value-added creation effect, and employment-inducing effect. In particular, this study attempted to redefine for the SRF. In addition, it was accessed by exogenous around the manufacture and utilization of SRF sector. The results show that production-inducing effect and value-added creation effect of expanding the manufacture and utilization of SRF facilities for the investment of 1.0 won are estimated to be 1.9993 and 0.6747, respectively. The employment-inducing effect of one billion of investment in the expanding the manufacture and utilization of SRF facilities is computed to be 11.1982 persons. This information can be utilized in predicting the economic effects of the manufacture and utilization of SRF.

The climate industry could be defined as the group of industries responding to world climate change compacts. This study confined it to renewable energy and analyzed the economic impacts of Korean renewable industry, using 2009 Input-Output Table. This study estimated that Korean renewable industry made the production-induced impact of 1.1644 won(Korean money), and the value-added-induced impact of 0.3544 won through an increase in output growth of 1 won. Its job-creation impact is analyzed to correspond to 10.065 labors through an increase in output growth of 1 billion won. And its industrial linkage effects including forward and backward ones are analyzed not to be so great as expected. According to these results, some policies vitalizing Korean renewable industry and relating industries to its value-chain as new growth engines are recommended.

School foodservice in the business opportunities could be magnified as the university and the general enterprise as well as elementary, middle, and high school. Therefore school foodservice creates commercially profitable and would go on its investment in social welfare service field as well as create new jobs. By using local food materials, school foodservice has economic effect on the society. This paper examines current state and related cases of school foodservices to discuss ways to vitalize school foodservice system. The study also examines the economic effect on consumers, producers and whole society. Especially, to test a ripple effect on the entire economy, input-output analysis has been used in the study.

The regional infrastructure industries of Gwangyang City, the subject of this study, are Gwangyang Port and Gwangyang Steel Mill. Therefore, it is necessary to analyze the regional economic ripple effects of the port logistics industry in Gwangyang City. In this study, a multi-stage approach using the RW and the LQ methodology using the national input-output tables in 2015 and 2019 is used to prepare the regional interindustry analysis chart in Gwangyang City, and an exogenous demand induction model that reclassified the port logistics industry was applied. Through this, the purpose of this study was to provide policy implications by figuring out the regional economic ripple effects of the port logistics industry quantitatively in Gwangyang City. As a result of the analysis, the industries with high production inducement effect and forward/backward linkage effect of the port logistics industry in Gwangyang City were analyzed as manufacturing, transportation, land and air logistics sectors. And the industries in which the added value inducement effect and the employment inducement effect were analyzed as an industry related to the service industry. Therefore, it is necessary to prepare support measures to foster the port logistics industry as a way to promote these industries and revitalize the local economy of Gwangyang City. To this end, it is desirable to improve policies and systems for the vitalization of the Gwangyang port maritime cluster and provide various policy support for the port logistics industry in Gwangyang City. This study is meaningful in suggesting policy implications for the regional economy of Gwangyang City based on the results of exogenous analysis of the port logistics industry in small and medium-sized cities. However, It seems that further studies related to this will be needed in the future.

This paper analyses the economic effects of the water industry on the Korean economy by using Social Accounting Matrix (SAM). The SAM is constructed based on the Input-Output table, National account and Family income and expenditure survey for Korea in 2009. Through the SAM multiplier analysis, I estimate the effects of water investment. As the results, this study has found the followings. i) output multiplier effects of water sector are 5.300~7.741, ii) value added multiplier effects of water sector are 0.685~1.158, iii) income multiplier effects of water sector are 0.511~0.984, iv) redistributed income multiplier effects of water sector are -0.096~0.247. The results indicate that a significant influence on the industrial production and the household income in Korea.

There has been a rising interest in cultural content industry as it may be one of the future growth engines to boost the economy of Korea. Cultural content industry has demonstrated high growth rates compared to any other industries. In the case of Busan, a variety of cultural content industry around games are being developed; however objective and quantitative research on the economic impact of this industry is inadequate. This study, therefore, analyses the economic impact of the cultural content industry of Busan in order to create a plan that would enhance the value of existing cultural contents.

전력산업의 경쟁체제 도입에 따른 전력설비 투자부진현상은 정전 발생 확률을 높였고, 이에 따른 대비책 마련 및 경제적 파급효과 분석과 관련된 연구가 대두되었다. 국내에서 수행된 정전의 경제적 파급효과 분석은 정전비용 산정에만 초점을 맞추어 수행되었기 때문에 잠재적인 경제적 영향성을 고려하여 정전과 금융시장의 상관관계 분석이 필요하다. 본 논문은 이벤트 스터디(Event Study)기법 적용을 통해 정전이 에너지 저장장치산업 관련 기업 주가에 미치는 영향을 분석한다.

신규 기술 기획시 해당 기술의 파급효과 중 하나로 관련 산업에 미치는 영향에 대하여 강조하는 추세이다. 그러나 시장이 형성되지 않는 제품에 대해서는 이러한 파급효과 추정이 용이하지 않다. 본 논문은 특허분석을 통하여 시장 현황 파악이 어려운 신규기술의 기획시 잠재 산업을 발굴하는 방법론을 제시하고 실증사례로 핵융합 실증로에 적용하고자 한다. 특허 분석 방법론은 특허 검색 범위에 따라 파악 가능한 잠재산업의 수준을 검토한다. 적정한 특허 검색 범위가 확인되면, 특허분석을 수행한다. 분석결과는 IPC 코드 등 특허의 산업 코드, 개별기업의 매출, 주제어 등을 활용하여 잠재산업을 발굴하는 방법을 제시한다. 이러한 방법론은 이미 기획된 핵융합 실증로에 적용하여 유용성을 검토한다,

이 연구는 '80년대 이후 많은 변화를 보이고 있는 정보통신 산업분야의 추세를 거시적으로 분석하기 위하여 '80년 이후 발표된 산업연관표(1980년, 1983년, 1985년)를 이용해 정보통신 산업이 국민경제에서 차지하는 역할과 타산업에 미치는 효과를 실증적으로 검증하였다. 분석결과 우리나라의 산업구조는 매년 고도화 되고 있으며, 특히 1차산업이 줄어듬과 동시에 3차산업과 정보통신산업의 비중이 증가하는 선진국형의 산업구조로 변화되고 있다. 1985년 현재 정보통신산업이 차지하는 비중은 4.54%로서 산출액은 8조6,468억을 기록하고 있지만, 성장율로 보면 정보통신서비스업은 1983년 대비 34.83%, 정보기기산업은 40.43%로 전체성장율을 훨씬 앞지르는 성장을 보였다. 그리고 국내 생산활동에 의하여 창출된 부가가치도 대폭 증가하였는데 부가가치비율은 1985년 전산업 평균이 41.35%이지만 정보통신서비스업은 60.71%로서 다른 어느 산업보다도 고부가가치산업임을 보여주고 있으며, 우리나라의 산업구조개선과 정보화 사회로 옮겨가는데 커다란 견인차 역할을 하고 있음을 나타내 주고 있다.
