The purpose of this study is to estimate the macro-economic ripple effect of tax exemption for both high end technology firms and research enterprises in R&D special cluster. We apply the user cost of capital model and the Input-output model to the estimation. Estimation results for 2007-2016 are as follows: the increase in both the production and the value-added is 2,807 and 1,392 hundred million Korean won, respectively. Also, employers are increased by 2,355 people. These imply that keeping the tax exemption item for certain enterprises in R&D special cluster may be beneficial to our economy.

The purpose of this paper is to analyze the effects of exports on Korea's employment and to decompose driving factors of change in Korea's employment embodied in exports (EEX). This study uses a multi-regional input-output (MRIO) and structural decomposition analysis (SDA) for empirical analysis, and uses a dataset of World Input-Output Tables (WIOTs) and Socio-Economic Accounts (SEAs) from the World Input-Output Database (WIOD). The main findings of the empirical results are summarized as follows. First, Korea's EEX continues to increase and Korea's share of EEX compared to total employment shows an upward trend. However, Korea's employment inducement coefficient of value-added exports showed a downward trend during the 2000-2014 period. Second, final demand from three countries (China, the United States, and the Rest of the World (RoW)) has affected a significant portion of Korea's EEX. Finally, from the results of the SDA, the effect of changes in final demand was the most important driving factor for the increase in Korea's EEX. Based on the results of this empirical analysis, this study discusses useful policy implications that could increase domestic employment in Korea.

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.

This paper is intended to analyze the toxic substances transmission between South Korea and U.S. through international trade, based on 2000 international input-output data and both country's toxic substances. According to result, The high TEI sectors are metal, chemical and general machinery in Korea, and the high TEI sectors of America are electric & electronics, Chemicals, Rubber and Plastics. Korea's export structure to America is more pollutant than America's export structure to Korea.

This paper presents theoretical explanations about the spill-over effects of domestic production of light rail transit and empirically investigates its effects on output, value-added and employment in the Korean economy. We distinguish net gains of domestic production from gross effects that bring about whether localized or imported cars are used. The input-output analysis is employed to fully capture the interaction among various industries involved. The empirical results reveal that net gains of domestic production such as import substitution, improvement of trade balances, and increase in output, value-added and employment are enormous. The cost reduction in construction, E&M systems, cars, management, and tariff and transportation is also significant.

최근 수년사이 우리나라 경제의 근간을 이루고 있는 중소기업의 부도사태가 갈수륵 확산되는 양상을 보이고 있다. 이로 인해 귀중한 경제자원이 사장되는가 하면 종업원이 실직을 당하고 부도기업과 거래해온 계열 및 하청업체들도 연쇄부도에 휩싸임으로써 연관산업은 물론 지역경제 및 국가경제에까지 큰 손실을 끼치고 있다. 따라서 어떻게 중소기업의 부도를 예방하고 그 피해를 최소화할 수 있느냐 하는 문제는 초미의 관심사로 대두됐다. 본 연구는 이같은 관점에서 중소기업부실화의 효율적인 예방대책마련에 필수적인 근거자료를 제시하는데 초점을 맞추고 있다. 이를 위해 설문조사를 실시하고 정책의 우선순위결정을 위한 통계적 모형인 AHP(analytical hierarchy process)모형을 이용해 설문조사내용을 분석한바, 부실화원인간의 계층적 구조가 파악되고 원인별 영향도가 계량화되고 있다. 이러한 연구결과는 부실화예방을 위한 정책의 우선순위결정이 가능함을 보여주는 것이다. 또 부실화연구에 새로운 접근방법을 구사한 점도 특기할만하다.

현재 국내 경제는 그 어느 때 보다 심각한 전환기에 처해 있다. 과거 한국이 갖고 있던 장점은 우수한 노동력이었으나 이제는 더 이상 경쟁력의 원천이 될 수 없다 남은 유일한 방법은 인적자원의 창조적 활용이다. 여기서 인적 자원은 산업사회의 단순한 노동력이 아닌 인력의 질, 즉 지식이다. 기업지식체계는 기업의 무형 지적자산을 체계적으로 창출, 축적, 활용하는 기반이며 지식경영의 핵심 기술이다. 본 논문은 지식 생산이 기업경쟁력 제고의 핵심으로 점차 그 중요성이 증대되고 있음을 주목하여 지식 창조적 기업 지식 체계를 위한 개념적 연구 모형을 제안한다 연구모형으로 우선 기업지식 창출과정이 소개되며 기업지식 형태와 연관관계가 파악된다. 이 지식창조과정에 근거하여 지식 사용자환경, 지식마이닝. 지식활용, 지식관리 서브시스템. 지식 리파지토리로 구성된 기업지식체계가 제시된다. 본 연구 모형은 향후 여타 지식경영 연구의 출발점으로 사용될 수 있도록 유연하게 구성되는데 중점이 주어졌다.

The study aims to analyze the effects of attracting companies from Seoul Metropolitan Area on regional value-added and employment using a regional input output model and to suggest the most appropriate categories in attracting business based on the result from the analysis. It is assumed that large manufacturing companies in Seoul Metropolitan Area are relocated to 5+2 supra-economic region in this paper. The result shows that selection of categories in attracting businesses should be depend on the characteristic of regional industrial structure. Also, it is derived that establishing a differentiated strategy in attracting businesses is essential.

This paper attempts to conduct a comparative analysis on the economic effects of integrated-energy and manufactured gas supply sectors. To this end, an input-output (I-O) analysis is applied using most recently published 2011 I-O table. In particular, the two sectors are specified as exogeneous to identify the economic effects on own and 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 analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect, value-added creation effect, and employment-inducing effect of integrated-energy and manufactured gas supply sectors are estimated to be 1.5461 vs. 1.0297, 0.4759 vs. 0.1941, and 2.2885 vs. 0.4053 respectively. Price pervasive effects of the 10% increase in integrated-energy and manufactured gas supply sectors are computed to be 0.0127% and 0.1585%, respectively. This information can be utilized in forecasting the economic effects of introducing integrated-energy or manufactured gas as a heating source and the impacts of a rise in price of integrated-energy or manufactured gas on price level of other sectors.

As the petroleum products produced from the Oil refinery industry (ORI), a national key industry in Korea, are supplied to other industries as an intermediate goods, the supply shortage of ORI has a large impact on the national economy. This paper attempts to analyze the supply shortage effects which are defined as the negative impact of one won of supply failure in the ORI on the production of other industries. To this end, an inter-industry analysis using an input-output (I-O) table describing inter-industry flow of intermediate goods is applied. More concretely, the supply-driven model is employed over the period 1990-2012. In addition, the results are compared with those for shipbuilding, semiconductor, and steel industries. The results show that the supply shortage effects are computed to be 0.9205 won when using 2012 I-O table. More specifically, the supply shortage effects on chemical products and transportation industries are computed to be 0.2113 and 0.1140, which are relatively large, The supply shortage effect of ORI is smaller than that of steel industry (1.4131 won), but larger than that of shipbuilding industry (0.0586 won) and that of semiconductor industry (0.1111 won).
