This study is to analyze the existence of the real buffer effect that reflects the effect of beginning-of-period inventory stocks effect on the demand for fixed investment, and the financial buffer effect indicates the substitution effect between end-of-period inventory stock and the source of financing for fixed investment. I use panel data of 361 Korean listed non-financial firms during 1990-2003. After the crisis, it also observed whether the relationship between inventory stocks and fixed investment has altered or not. I review the theoretical connection between inventory stock and fixed investment through the paper by Bo(2004) and estimate the investment model by the method of GMM-SYS. The results show negative relation between end-of-period inventory stock and fixed investment in the whole period and each period classified, also it confirms that the relation between fixed investment and end-of-period investment is significantly negative. It can be interpreted through two aspects that firms not only use inventory stock as a buffer in response to unexpectedly high demand, but also utilize inventory stock as a source of financing for fixed investment. The results imply that firm's decision-making is much correlated with production-and-inventory stock adjustment, decision-making about fixed investment, and decision-making about financial affairs.

본 연구는 국내 지역R&D투자와 지역경제지표 간의 관계를 파악하기 위한 것이다. 연구 방법은 패널VECM을 사용하여 1995~2014년 국내 17개 시 도별 정부 및 민간R&D투자, 고정자본과 고용, 지역내총생산의 상호 간 장 단기 인과관계를 도출하였다. 분석결과, 단기적으로 GRDP의 원인변수는 고정자본, 고용, 그리고 민간R&D투자로 나타났다. 고정자본의 원인변수는 고용, 민간R&D투자로 나타났으며, 고용의 원인변수로는 GRDP와 고정자본으로 나타났다. 장기적으로 고용, 고정자본, 정부R&D투자가 다른 변수들의 장기균형관계로부터 각각 인과관계를 갖는 것으로 나타났다. 이와 같은 결과를 바탕으로 목적과 대상 그리고 시간의 흐름에 따라 지역R&D투자의 직 간접적 효과를 함께 고려할 수 있는 추가적인 분석이 요구된다.

고정 투자율법이란 (Fixed Permeability Method : FPM) 시스템이 자기적으로 포화 상태에 있을 때 각 요소별 동작지점의 투자율을 고정하여 선형적으로 시스템을 재해석하는 방법으로, 두 가지 이상의 자계원에 의해 포화가 발생할 경우, 각각의 영향을 구분지어 포화시 철심내의 자계 비선형 문제를 해석할 수 있다. 본 논문에서는 제안된 고정 투자율법을 적용하여 자기 포화가 발생하는 영역까지를 운전 영역에 포함하는 매입형 영구 자석 전동기의 특성 값들을 추출하는 방법을 제시하였으며, 실험값과의 비교를 통해 그 타당성을 검증하였다.

This study analyzed the financial information between 2011 and 2014 comparing management performance and utilization of capital and human resources between private non-profit general hospitals and regional public hospitals operated as general hospitals. The purpose of this study was to enhance the productivity for financial independence of regional public hospitals. Comparison analysis variables were value added to the total assets, value added to the productive activity tangible fixed assets, value added to personnel expenses, ratio of value added, and operating margin to revenues. According to the analysis results, regional public hospitals showed lower investment efficiency indicator and higher ratio of value added, as well as significantly lower operating margin-to-revenues compared with private non-profit general hospitals. Moreover, the effect of investment efficiency indicators on operating margin-to-revenues was value added to the productive activity of tangible fixed assets and value added to personnel expenses in regional public hospitals; the value added to personnel expenses in private non-profit general hospitals had a significant effect on the operating margin-to-revenues, the effect of value added to personnel expenses was the greatest. Therefore, it is necessary to asset utilization to the revenue and propriety of human resources to personnel expenses in regional public hospitals.

In this paper, we analyse empirically the fixed asset investment smoothing of working capital of firms listed on Korea Securities Market. The main results of this study can be summarized as follows. Firms will seek to lower long-term cost by smoothing fixed asset investment and maintaining stationary investment with working capital. Working capital is not only an important use of fund, but also a source of liquidity that should be used to smooth fixed asset investment relative to cash flow shocks if firms face financial constraints. Working capital investment is more sensitive than fixed asset investment to cash flow fluctuations. If firms face financial constraints, working capital investment will compete with fixed asset investment for the limited pool of available cash flows. So, fixed asset investment will have negative relationship with working capital investment. However, criticism that the positive correlation between cash flows and fixed asset investment could arise simply because cash flows is proxy variable for investment demand. Finally, controlling for the fixed asset investment smoothing effects of working capital results in a much larger estimate of the long run impact of financial constraints. Financial constraints is measured by dividend payout ratio and market access level. Fazzari et al. (1988), Fazzari and Petersen (1993), and Faulkender et al. (2008) emphasize that low dividend firms or market unaccessible firms are more likely to face financial constraints, and rarely make use of new equity issuing. The results from empirical analysis show that financial constraints can be better explained using 'adjustment cost' concept. Specifically, the results show that financial constraints exist and that in order to measure financial constraint effects more succinctly, fixed asset investment smoothing effects with working capital should be considered.

지난달 9일에는 교내에서 ESCO 2차사업 추진을 위한 기공식을 가졌다. 2차사업이 완료되면 그동안 냉난방 설비시설 가동을 위한 34명의 기기가동요원이 12명 수준으로 줄어들고 열악한 근무환경도 벗어나게 된다. 또 노후된 전기 및 설비시설 개선을 위해 연평균 4내지 5억여원이 고정투자되던 시설보수비가 절감되어 다른 노후시설 개선에 집중투자할 수 있는 여건이 마련된다.

본 논문은 국내세법, 한 중 조세협약, 중국세법을 근거하여 특수목적회사(SPC), 사모펀드(PEF) 등의 간접투자 방식과 직접투자 방식에 대한 투자시뮬레이션을 활용하여 최상의 투자형태 협상전략을 제시하였다. 분석결과 중국내 고정사업장이 없는 경우 홍콩과 같은 조세회피지역에 특수목적회사를 설립하여 중국에 투자하는 형태가 직접투자 혹은 국내에 PEF 설립을 통한 투자보다 더 합리적이었다. 더욱이 특수목적회사는 국내의 여러 가지 규제에서 벗어나 자유로운 펀드운용과 새로운 투자추진시 국내과실 송금 처리절차를 거치지 않고 재투자가 가능하다는 점을 포함하여 다양한 장점을 가지고 있었다. 중국 등의 해외투자 고려시 조세회피지역에 특수목적회사를 설립하고 이를 통해 투자를 실행하는 것이 가장 효율적인 방안임을 고려하여 투자방식과 JV협상을 진행하여야 할 것이다.

The study has been carried out to understand productivity-related factors that have been connected to improve financial independence rate of national university hospital. In order to achieve such research purpose as working out implications of efficient resource management, data from the four years between 2007 to 2010 of 12 national university hospitals were reviewed. According to the results, the hospitals came up with significant differences in Value Added to Total Asset, Value Added to Tangible Fixed Assets, Value Added to Personnel Expenses and Value Added Ratio to Patient Revenues. In addition, after the relation between the investment efficiency and profitability of the national university hospitals was investigated, it was learned that application of basic environmental factors would have an influence on a profitability index Operating Margin. As long as the basic environmental factors are adopted, Operating Margin of the national university hospitals is improved under the condition that the Value Added to Tangible Fixed Assets for Production and the Value Added to Personnel Expenses gets higher but the Value Added Ratio to Patient Revenues gets lowered.

This paper investigates empirically the impact of foreign investors on a firm's dividend and investment decision making in Korean stock market. Empirical results using the sample firms in non-financial firms listed in Korean stock market whose settlement month are December, we find that foreign investors who declared participation in management didn't exert significant impact on dividend increase. In the case of investment, foreign investors exerts significant impact on R&D investments. Using Hausman-Taylor Instrumental Variable method, we controlled endogeneity problem related with foreign ownership and dividend and investment policy. The contribution of this paper is that the purpose of foreign investors whether or not participate in management is the most critical point and the impacts of foreign investors on dividends and investment are different whether they participate in management or not.
