The purpose of this study is to analyze the structure, status and economic ripple effects of the fisheries processing industry in Korea using interindustry analysis. Five input-output tables published over the past twenty years have been reclassified with a focus on the fisheries processing sector. Through these multi-period tables, we analyzed changes in the inducing effects in production, value added and employment as well as the backward-forward linkage effects. As a result of the analysis, it was found that the industrial scale of the fisheries processing industry is very small compared to other food manufacturing industries. The backward linkage effect of the fisheries processing industry was greater than that of other industries, but the forward linkage effect was rather low. This means that the fisheries processing industry can be greatly affected by industrial depression of the downstream industries such as fishery and aquaculture. Production and employment-inducing effects of the fisheries processing industry have shown a decreasing trend in recent years. This reflects the reality that intermediate inputs are gradually being replaced by imports from domestic production due to the expansion of market opening and the depletion of fishery resource. In the future, it is necessary to prepare a strategy to increase the value-added productivity of the fisheries processing sector and foster it as an export industry.
본 논문은 한국의 연구개발투자가 제조업구분에 따른 파급효과들을 산업연관분석을 이용하여 분석하고 있다. 연구 방법은 2010∼2014년 국내 산업연관표 상에서 연구개발투자 부문을 외생화하고, 경제협력개발기구(OECD)의 기술수준 분류표에 입각하여 기술수준별로 제조업을 분류하여 연구개발투자가 미치는 생산유발효과와 부가가치유발효과를 분석하였다. 분석결과, 연구개발투자의 기술수준별 제조업 구분에 따른 생산유발효과는 중고기술과 중저기술에 속한 제조업에서 높은 것으로 나타났으며, 부가가치유발효과 역시 중고기술 제조업에서 높은 것으로 나타났다. 반면 연구개발투자가 가장 많은 고기술제조업에서 생산유발효과와 부가가치유발효과가 상기 2부문보다 낮은 것으로 분석되었다. 이러한 결과들은 한국 제조업이 연구개발투자를 통해 기술수준의 제고를 달성하고 이를 산업구조의 고도화로 이어간다는 품질사다리론과 연계되지 않았음을 의미한다. 이러한 분석결과로부터 한국의 연구개발투자가 고기술제조업의 생산유발과 부가가치효과의 증대를 위해 구조조정이 필요하다는 시사점을 얻었다. 본 논문은 산업연관표의 구조적 특성으로 인해 연구개발투자의 시차를 고려하지 못한 한계를 안고 있다.
The VHTR (Very High Temperature gas-cooled nuclear Reactor) has been considered as a major heat source and the most safe generation IV type reactor for mass hydrogen production to prepare for the hydrogen economy era. The VHTR satisfies goals for the GIF (Generation IV International Forum) policy such as sustainablility, economics, reliability and proliferation resistance and physical protection, and safety. As a part of a VHTR economic analysis, we have studied the VHTR construction cost and operation and maintenance cost. However, it is somewhat difficult to expect the ripple effect on the whole industry due to the lack of information about Inter-industries relationship. In many case, the ripple effect are based on experts’ knowledge or uncertain qualitative assumptions. As a result, we propose quantitative analysis techniques for ripple effects such as the production inducement effect, added value inducement effect, and employment inducement effect for VHTR 600MWt×4 modules construction and operation ripple effect based on NOAK (Nth Of A Kind). Because inducement effect values have been published annually, we predict inducement effect’s relation function and estimated values including production inducement effect value, added value inducement effect value, and employment inducement effect value using time series and estimated values are verified with published inducement effects’ value. This paper presents a new method for the ripple effect and preliminary ripple effect consequence using a time series analysis and inter-industry table. This ripple effect analysis techniques can be applied to effect expectation analysis as well as other type reactor’s ripple effect analysis including VHTR for process heat.
The economic effects of sewage and wastewater treatment service (SWTS) sector on other sectors have been rarely investigated in the literature. This paper attempts to apply an inter-industry analysis to looking into the economic effects of the SWTS sector. To this end, the most recently published 2012 input-output table is used here. In particular, the SWTS sector is specified as exogeneous to identify the economic effects of the SWTS sector on other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are also analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect and value-added creation effect of a unit of investment or production in SWTS sector are estimated to be 1.7076 and 0.7392, respectively. The employment-inducing effect of one billion of investment or production in the SWTS sector is computed to be 11.0498 persons. The shortage effect of the SWTS sector amounts to 0.8417 won. The overall price effect of the 10% increase in the price of SWTS sector is calculated to be 0.0115%. This quantitative information can be utilized in predicting the economic effects of the SWTS sector-related activities or policy-making.
This paper to empirical examine the date from 2007 to 2010 China's ODI in 103 countries, found that a lot of overseas theory and experience hypotheses to explain China's ODI is not suitable for a large part. China's outward FDI to the investing countries are the main factors that affect the size and potential of the markets, the open level of market, such as the degree of technological development. But China's enterprises towards the presence of exchange and other financial risks that are not realize. The average wage level, the exchange rate of the traditional FDI determinants influenced the theory and existing research findings conflicting results were obtained. The strategic implications for Korean government and enterprises are as follow: First, China to take advantage of new investment source need to target strategies. Second, the extension of Korea's market should be expanded. Third, the investment environment should be open for the Chinese capital in Korea. Fourth, the response to M&A of China's enterprises should be prepared in advance. Fifth, we should be prepared that compete with foreign manufactured products by China's enterprises.
A lot of rural development projects have been planned and implemented for revitalizing rural areas in South Korea. However, it is not easy to properly evaluate and quantitatively analyze project outcomes. For this reason only selected regions have been evaluated for rural projects by government agencies. In this study, we analyzed the purpose and the contents of the Rural Village Development Project (RVDP) and Green Tourism Village Project (GTVP) to find indicators for evaluating results of rural projects using logistic regression analysis. Outputs of this study show that RVDPs increase regional population and GTVPs positively affect the sales of agricultural products. We also estimated the spatial distribution of project effects through spatial autocorrelation analysis and local-spatial autocorrelation analysis. Results show that the Moran's I values for the proportion of farmers with avocational jobs, product sales changes, and population growth in Jeol-La province are positive and the biggest one is population growth. Especially, key areas of agricultural product sales are widely distributed.
In this paper, we estimated the economic impacts of Korea-EU FTA on the agricultural sector in GyeongGi-Do. In particular, we estimated the economic impacts of agricultural production decrease resulting from Korea-EU FTA for 31 sub-regions in GyeongGi-Do by 15 industrial sectors. We employ a regional economic impact model combining a regional input-output model with a spatial allocation model. We found that the size of inter-industrial impacts are quite different across regions. Our results suggest the importance of agricultural and industrial policy considering the impacts of industrial sectors at the regional level.
