제조업을 중심으로 분석한 환경관련투자 효율성의 주요 연구 결과는 다음과 같다. 내부수익률과 편익의 현재가치를 가변비용절감부문, 투자비용절감부문, 임대수입부문으로 분해함으로써 기존 연구의 범위를 확장했다. 그리고 단기총비용과 임대수입의 역할을 탐구하여 편익의 현재가치는 편익의 크기만을 나타내는 반면, 내부수익률은 효율성의 존재여부를 나타냄을 발견했다. 그리고 내부수익률과 시장이자율을 비교하는 투자효율성 방법론으로 환경관련투자와 관련된 투자효율성과 편익을 분석함으로써 사후 비용편익분석을 수행했다. 그 결과 환경투자, 공해방지투자 모두 비효율적인데, 공해방지투자가 환경투자보다 더 비효율적임을 발견했다.

Subscriber network investment cost is a main cost element among those constituting the access charges in telephone networks. The purpose of this paper to estimate the investment cost of installing a subscriber network in a typical metropolitan area and to develop a cost modeling framework. To this aim, a metropolitan area in Seoul was investigated. The main cost elements were identified and their relationships with the cable technology, geographical characteristics, and the number of subscribers were analyzed. The findings could be used to design an enhanced cost proxy models for estimating the access charges in a multi-operator environment.

This paper considers a supply chain consisting of a manufacturer under the cap-and-trade emissions regulation and a permit supplier. We study joint production quantity and investment in reducing permit production cost decisions for centralized and decentralized supply chains. We formulate two supply chain contracts with aims to coordinate the decentralized supply chain; wholesale price contract and cost-sharing contract. Under the cost-sharing contract, the manufacturer shares a part of the investment in reducing permit production cost and then is allowed to purchase emission permit at a lower price. We analytically find that the proposed cost-sharing contract with reasonable parameters can coordinate the supply chain whereas the wholesale price contract is not desirable to achieve the system-wide profit. Numerical example is followed to support the analysis.

The capital cost of the company is one that must be paid to the money owner as the price by using the money. The capital cost according to the source of money supply can be estimated by the expected profit rate undertaken by the use of the capital. But in the area of pre-existent economic evaluation, the evaluation of the company investment has been treated by the profit rate of the capital after considering the repayment conditions of the other's money or the interest. Thus in this study, in case the company makes an investment on various kinds of the capital at the same time, not make use of the capital as a one source, the economic evaluation of an investment should be handled by taking the weighted average cost of capital into consideration in proportion to the constitution of the capital cost by the sources of money supply, Especially, as the cost of the private money is very much connected with the profit rate through the stock market, the Capital Asset Pricing Model (CAPM) will be applied. This kind of economic evaluation method can be said to have much to do with the Economic Value Added : EVA) as well as to be highly thought as a standard to estimate the company' value recently To certify the usefulness of this approach, the case study of the output of the capital cost will be made for the purse of the economic evaluation of the alternative investment by using the financial statements of a motor company H.

비용편익분석은 어떤 사업으로 인하여 자연배분의 변화가 생길 때 그에 따른 경제적 편익을 측정하게 되며 사업을 시행하여 생기는 편익과 비용을 비교하여 경제성을 평가하고 대안 중에서 우선순위를 결정할 때 유용하다. 따라서, 본 논문은 자본에 관한 투자기준을 마련하기 위해서 분석용 모델인 "비용편익분석"을 활용 하여 제조기업의 어떤 사업계획에 의하여 생겨나는 자본요소가 어떻게 투자되어야 생산비용을 최소화 할 수 있는지를 자본투자에서 가장 핵심적인 생산설비투자와 기술개발투자에 대한 비용편익분석을 통하여 그 방법론을 제시함으로써, 자본투자에 있어서 "비용효과분석"의 활용성을 확인하고자 한다.

It is expected that the market of residential facility for retired seniors will be a new investment field for construction firms. This study describes the questionnaire survey analysis results of potential customers' demand for the facility. For comparison purpose, direct construction cost was estimated by estimation experts. In addition, a case analysis was conducted to compare direct cost and indirect project cost with the experts' estimation. According to the questionnaire survey analysis, it is observed that there were significant differences in demand between groups which are classified by the regions, living expenditures, the level of property ownership and the scales of residence. From an investor's perspective, investment decision on residential facility for retired seniors should be made considering bothe the level of returns which can be generated from the investment and the customers' needs.

Before expanding of distribution automation application to distribution network, we must examine whether there are economical effect. Investment expense for distribution automation can be divided into facility investment expense, maintenance expense, communication expense, investment expense etc. Effect of distribution automation can classify by effect that can convert into money and effect that can not convert into money. Representative effect is outage time decrease effect, distribution line loss decrease effect, main transformer upload effect, distribution line upload effect, work environment improvement effect of lineman and so on. This paper studied economical effect and break-even Point for investment expense by using data that acquire in KEPCO's distribution network.

This paper deals with the optimal investment method for distribution facilities, based on the analytical approach for the reliability assessment in distribution systems interconnected with new dispersed generations. The existing approach can estimate the expected reliability performance of distribution systems by a direct assessment of the configuration of the systems using the reliability indexes such as NDP(Non-Delivery Power) and NDE(Non-Delivery Energy). The indexes can only consider the number and configuration of the load, but can not consider the characteristics of the load which is the one of the most important factor in the investment cost for the distribution systems. Therefore, this paper presents the new performance indexes for the investment of the distribution facilities considering both the expected interruption cost for the load section and the operation characteristics of dispersed generations. The results from a case study show that the proposed methods can be a practical tool for the voltage management in distribution systems including dispersed sources.

중앙정부의 환경투자 관련 제조업의 비용구조를 트랜스로그 가변비용함수를 활용하여 분석하였으며, 주요 결과는 다음과 같다. 첫째, 중앙정부에서 진행하는 환경투자의 적정 여부를 파악하기 위해 충족도를 살펴본 결과, 적정수준인 1에 못미치는 0.7230으로 분석되었으며, 이에 따라 생산비효율이 발생하고 있다. 그러므로 중앙정부는 환경투자를 적정수준으로 끌어올릴 수 있는 방안을 마련해야 할 것이다. 또한 중앙정부는 환경투자의 부족에도 불구하고 잠재가격이 시장가격보다 작아 투자여건은 유리하지 않다. 그러나 중앙정부의 환경투자는 제조업체의 산출증대를 가져오고, 가변비용을 절감하며, 규모의 경제를 가져오는 것으로 분석되었다. 둘째, 제조업체의 공해방지투자와 중앙정부의 환경투자를 비교해 본 결과, 전자 후자 모두 투자가 적정수준에 못미치고, 투자여건이 양호하지 못하며, 규모의 경제를 가져오고, 산출 증대에 기여하는 것으로 나타났다. 특히 중앙정부의 환경투자는 정(+)의 잠재가격에 따라 효율적이므로 가변비용을 절감하게 된다. 이에 따라 제조업체는 중앙정부의 환경투자 부족이 가변비용을 증가시켜 생산비효율을 가져오고 있다. 그러나 제조업체의 공해방지투자는 부(-)의 잠재가격에 따라 비효율적이므로 가변비용을 절감하지 못하고 있다. 이러한 제조업체의 공해방지투자 부족은 오히려 가변비용을 절감시킴에 따라 생산효율을 가져오고 있다. 그러므로 제조업체는 공해방지투자를 적정수준으로 끌어올려 효율화함으로써 가변비용을 절감시켜 생산효율을 달성해야 할 것이다.
