최근 한국(韓國)을 비롯한 동(東)아시아지역(地域) 몇 나라들의 성공적인 성장업적(成長業績)에 자극되어 이들 국가들의 성공사례를 모형내(模型內)에서 이론적으로 설명해 보려는 노력이 활발히 진행되고 있다. 이 글에서는 최근의 이러한 노력의 일환으로 개발되고 있는 '내생적(內生的) 성장이론(成長理論)'을 개관하고 그 함의(含意)와 한계점(限界點)을 정리해 보았다. 먼저 내생적(內生的) 성장모형(成長模型)의 비판대상이 되고 있는 신고전파(新古典派) 성장모형(成長模型)의 한계점(限界點)을 요약하고 대체모형(代替模型)으로 제시되고 있는 몇 가지의 대표적인 신성장모형(新成長模型)을 그 특성별로 구분하여 정리하였다. 성장(成長)의 기본적 동인(動因)이라고 할 수 있는 기술진보(技術進步)나 인적자본(人的資本)의 축적(蓄積)을 내생화시키고 이를 통해 국가간(國家間) 성장률(成長率) 격차(隔差)를 모형내(模型內)에서 설명하려고 시도하는 등 여러 가지 새로운 이론적(理論的) 혁신(革新)이 이루어지고 있으나, 아직 비현실적인 수학적(數學的) 가정에 의존하고 있고 모형(模型)의 경직성으로 인하여 성장과정(成長過程)의 설명에 필수적인 주요 이슈들이 간과되어 있다는 점 등을 지적하였다.

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.

Using the soils containing several arbuscular mycorrhizae, the degrees of infection on the plant roots were measured with the different level of phosphate added on pot cultures. Infection on the plant roots was independent of the phosphate level for the roots of sorghum, but formation of arbuscular mycorrhizae in the roots was inversely related to the growth of soybean roots. It was concluded that infection of arbuscular mycorrhizae would be related to the phosphate level in the soils. Plants, themselves, were considered to control the infection of arbuscular mycorrhizae under the environments of soils, especially amount of phosphate.

본 연구는 지난 30년간(1975-2004년) 한국의 경제성장과정에서 교육의 부문별(초등 중등 고등교육) 역할을 추정하는 데 주목적이 있다. 본 연구는 우선 신고전학파 Solow의 외생적 경제성장이론을 접목한 Cobb-Douglas 모형을 확장하여 1인당 경제성장 추정을 위한 내생성장모형을 제시하였다. 또한 자료 한계를 극복하기 위하여 동아시아 7개국 자료를 바탕으로 시계 및 횡단면 자료를 블록으로 구축하여 앞의 내생성장모형을 이용한 pooling방법으로 1인당 경제성장에 물적자본, 단순노동력, 인적자본, 지적자본(R&D), 초기년도의 기술수준 등의 기여분을 추정하였다. 이러한 각 생산요소의 직접적인 추정결과로부터 각 요소간(고등교육, 중등교육, 지적자본) 상호작용으로 인한 간접적인 기여분 추정을 위해 연립방정식체계를 구축하고 각 요소의 영향력을 재 추정하여 보정된 결과를 제시하였다. 1975-2004년간 한국의 경제성장 과정에 있어서 인적자본요소인 교육은 40.7%를 기여였으며 이를 다시 분해하면 중등교육이 가장 큰 87.0%, 초등교육이 6.6%, 중등교육에 간접적으로 기여한 대학교육이 -52.9%를 보였다. 물적자본이 39.6%, R&D자본이 24.1%들 보였으며 지식 정보기반사회에서 그 의미가 감소한 단순노동력은 -1.4%, 기술추격을 가능케 하는 1975년도 초기기술수준이 -3.0%의 추정결과를 보여주고 있다. 향후 정책연구 과제로는 한국미 지식기반사회에서 선진국으로 진입하기 위해서는 경제성장과정에서 대학의 역할을 제고할 필요성이 있음을 제안하고 있다. 이를 위해서는 기존 대학의 양적인 구조조정이 필요하다. 특히 대학의 질적 경쟁력을 높이기 위한 정부의 대학 지원 역할 역시 제고되어야 할 것이다. 또한 이 글은 교육시장과 노동시장을 어떠한 방법으로 연계 시키는가를 논의하고 세계시장의 급격한 기술변화와 체제변화에 따라 국내노동시장의 필요한 산업인력수요의 내용도 같은 속도의 변화를 요구하고 있음을 상기시키고 연계지원 정책을 주장하고 있다.

This study researches the correlation between the firm value, which can be represented as Tobin's Q in this paper, and other financial information. The research is based on the financial statistics of KOSDAQ-listed Venture manufactures, which is comprised of the venture businesses group and the general group. The multiple regression, the correlation test tool, shows the R&D expenditures and tangible assets have the positive relation with the firm value while training expenses and the return on assets have the negative one. More specifically, R&D expenditures and total assets have the affirmative relations with the firm value among the venture businesses, whereas tangible assets, advertising expenses, and training expenses have the negative ones. The positive correlation between total assets and the firm value of venture business, shows that the volume of intangible assets impacts on the firm value of venture businesses. It also reflects the features of venture businesses highly relying on the technology development. The results are summarized as follows: First, The R&D expenditures and firm value have been positively correlated in the KOSDAQ-listed companies. Second, total assets and firm value has the positive correlation in the venture businesses.

This paper examines the recently empirical test for the two types of endogenous growth models, which one is more fitted to real data. We adopt the non-stationary panel data methodologies for seeking empirical implication by using productivity and R&D data in the OECD over the past two decades. The Empirical tests show that there is a robust relationship Total Factor Productivity and R&D variables implied by semi-endogenous growth model. The relationship suggested by fully endogenous growth theory, however, is sensitive to R&D variables. Therefore, the estimation results provide empirical evidence in favour of endogenous growth theory of R&D expenditure role for sustaining economic growth. The sustained Total Factor Productivity, however, is maintained by more increasing R&D inputs for overcoming diminishing return to R&D efforts.

The main theme of this paper was to investigate the role of education as a source of economic growth in Korea. In this study, first, the objective mode was built by extending neoclassical Solow growth theory. Second, the capital deepening typical of an endogenous economic per-capita growth model was developed empirically for seven East-Asian economies as for the medium term, during $1975{\sim}2004$. And then we found the meaning of coefficients of growth factors, direct relative contribution of each input to per-capita growth in seven East-Asian countries, relative indirect contribution of education to per-capita growth in Korea, accounting for difference due to accumulation in Korea. The indirect relative contributions of secondary and higher education and R&D to per-capita growth change the results somewhat. Secondary education is still the largest single contributor 83.6 percent of predicted growth is due to secondary school enrollment in Korea. Primary education comes second with 37.5 percent and followed by higher education at -52.9 percent. Physical investment gives 62.3 percent and unimproved raw labor contributes only -1.4 percent.

In the period of rapid economic growth, it is possible to practice the growth policy by factors input and the regional development policy by the dispersion of growth. But, in the period of weakened growth, this model loses its theoretical and practical merit. The endogenous regional development model that can efficiently cope with a international competition and a uncertainty of international economy become an alternative policy of growth and regional development. France, which had a problem of overcrowding in the capital region by the centralized growth policy and regional development policy, phase the regional innovation system policy in order to establish the foundation of an endogenous regional development from the 1970's. The regional innovation system policy in France which pursues simultaneously the systematic regional knowledge creation and the regional development is very suggestive to the regional innovation system policy in Korea that pursues the endogenous regional development and the solution of the regional disparity.
