본 연구는 에너지정책을 종합적 차원에서 일반경제정책과 병행하여 정량적으로 분석할 수 있는 수리모형 (numerical multi-sector general equilibrium model)을 개발하기 위하여 시도되었다. 모형은 크게 (i) 가격/기술변화 반응적인 투입-산출계수를 내생화한 "산업간 거래모형 (inter-industry production model)", (ii) 민간에 의한 최종부문 수요를 나다내는 "소비자 선택모형 (consumer choices model)", 그리고 (iii) 생산물시장과 본원적 투입요소시장, 수출입시장 등에서 민간기업 정부 및 해외라는 개별 경제주체간의 행태를 반영하는 "거시경제 (성장) 모형 (macro-econometric growth model)"으로 구성되어 있다. 이러한 방법은 분석경제를 충분히 세분하고 제(諸)경제변수들의 동시결정적 과정을 중시한 일반균형적 /부문적 접근방법 (general equilibrium/sectoral approaches)을 취함으로써 지금까지 단순한 거시경제모형(aggregate macroeconomic models)이나 전통적 산업연관모형 (static input-output models)에만 의존해 오던 경제예측이나 경제 및 에너지관련 정책의 효과분석이 한층 더 강화될 수 있을 것으로 기대된다.

Estimated coefficients has serious problems including inconsistency, biasness, etc. because many researches about the effect of fiscal decentralization on a country's economic growth use the traditional OLS method. Researches use the data intactly so that so called "spurious regression" phenomenon exists. This causes fundamental fallacy. This research tries unit root test, cointegration test, and then estimates the United States' economic time series by using VECM. The analysis of the effect of the state level-fiscal decentralization on economic growth shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth move the same or different directions. In case of prediction GDP increases steeply and then from 2015 gently; and fiscal decentralization index shows a general reduction trend and then decreases slowly. At local level it shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth also move the same or different directions. Impulse response analysis shows the very negative effect of fiscal decentralization on economic growth.

연구개발투자의 촉진과 가용한 연구개발자원의 효율적 배분을 위해서는 연구개발투자의 경제적 효과에 대한 이론적이고 실증적인 분석을 통해 연구 개발투자의 효과를 정량적으로 입증할 필요성이 있다. 본 연구에서는 연구개발투자가 경제 성장에 미치는 직접효과와 기술 및 기술능력을 통해 경제성장에 미치는 간접효과를 실증적으로 분석하고자 한다.

The purpose of this research is to conduct the empirical analysis of the short- and long-term causal relationship between public R&D investment, corporate R&D investment, and university R&D investment on economic growth in Korea. To this end, based on the time series data from 1976 to 2020, a causality test was conducted through the unit root test, cointegration test, and vector error correction model (VECM). As a result, it was found that there is a long-run equilibrium relationship between economic growth in Korea, public R&D investment, corporate R&D investment, and university R&D investment, in which a causal relationship exists in the long run. Also, while public R&D investment has a short-term effect on economic growth, corporate and university R&D investment does not have a short-term effect on economic growth. In addition, the results shows that there is a bidirectional causal relationship between economic growth and public R&D investment, corporate R&D investment and public R&D investment, and university R&D investment and public R&D investment in the short term. Through this research, it was empirically found that a highly mutual relationship exists between public R&D investment, corporate R&D investment, university R&D investment and economic growth. In order to increase the ripple effect of R&D investment on economic growth in the future, R&D investment between universities and corporations should be mutually promoted, and R&D investment by corporations should have a positive effect on public R&D investment so that public R&D investment can contribute to future economic growth.

This paper examines the effect of bargaining power over intermediate goods prices on innovation and economic growth using a Schumpeterian growth model. The notion of "intermediate goods prices" broadly indicates the reward to innovators including innovative SMEs as well as intermediate goods producers that are vertically integrated to big businesses. From this viewpoint, this paper sets up a Schumpeterian growth model that incorporates the market power between final goods producers and intermediate goods producers. The results show that the reduction of intermediate goods prices slows down long-run growth rates as it erodes the reward to innovations. Lower intermediate goods prices decrease marginal productivity of capital and real interest rates. However, the harmful effect of lower profits on innovations outweighs the beneficial effect of lower interest rates. Simulations using Korea's data for various cases show that in all cases the policies that raise the share of intermediate goods producers are as powerful as the R&D subsidy policies in raising growth rates. Therefore, fair trade policies that enable intermediate goods producers-especially SMEs to obtain more fruits of innovations will be helpful for long-run economic growth.

The purpose of this study is to examine relationship between water consumption and economic growth in Korea, and to obtain policy implications of the results. To this end, we attempt to provide more careful consideration of the causality issues by applying rigorous techniques of Granger causality. Tests for unit roots, co-integration, and Granger causality based on an error-correction model are presented. The existence of bi-directional causality between water consumption and economic growth in Korea is detected. This finding has various implications for policy analysts and forecasters in Korea. Economic growth requires enormous water consumption, though there are many other factors contributing to economic growth, and water consumption is but one part of it. Thus, this study generates confidence in decisions to invest in the water supply infrastructure. Moreover, this study lends support to the argument that an increase in real income, ceteris paribus, gives rise to water consumption. Economic growth results in a higher proportion of national income spent on water supply services and stimulates further water consumption.

그 동안 R&D와 관련된 많은 연구는 다양한 성장모형을 이용해 경제성장과 연구개발 투자사이의 관계를 보이는데 중점을 두어왔으나, 디지털 경제에서의 지식 혁신에 의한 R&D활동의 성장패턴을 보이는 연구는 이루어지지 않고 있다. 따라서 본 연구에서는 W기업의 생산과정에서 R&D활동에 따른 비중의 변화가 생산성을 증가시키는 성장의 패턴을 다양하게 할 수 있음을 보이고자 한다.

We empirically examine the validity of second generation endogenous growth theory suing 21 OECD countries' panel data(1981~2011). Due to non-stationarity in all variables, we test the cointegrated relationships strongly supporting the semi-endogenous growth model. In the estimation of total factor productivity growth function, the growth of domestic and foreign R&D investment levels statistically significantly affect total factor productivity growth. R&D intensity, however, has significant impacts on the total factor productivity growth only in a few models, and international technology gap also has positive impacts on GDP growth. Thus the semi-endogenous growth model is relatively supported while fully endogenous growth model is weakly and occasionally supported in OECD countries. The policy implication of supporting the semi-endogenous growth model is that the sustaining growth requires increasing R&D expenditures.
