This paper is conducted to find out if the previous corporate internal reservation has a significant effect on current investment and dividend payments by using the dummy variables of each classified industry. The results of the research show that previous corporate internal reservation had a significant effect on current material investments in following fields - manufacturing industries, technical services, wholesale and retail industries, information services, construction and transportation industries - over two years. Especially, investments in tangible assets were more effective than those in development expenses. In human resource investment, previous corporate internal reservation had a significant effect on current human investments in fields of manufacturing, technical services, information services and transportation industries. Among them, investments in education training expense and welfare benefit expense were more effective than those in wages. In the dividend section, previous corporate internal reservation had a significant effect on current dividends in the fields of manufacturing, wholesale and retail, information services, transportation industries, and in other businesses. Among them, Expenditure on dividend amounts was found to be more effective than that on dividend ratio. This paper contributed to the field in a way of empirically demonstrating the effects of previous corporate internal reservation on current investments and dividends by using the method of industrial classification. On the other hand, it also has a limitation since collecting precise taxation data was practically difficult. Therefore, a further developed study is required to find out the standard which shows exactly how much the measured results of the regression analysis reflect the effects of the government policies. Moreover, it is considered necessary for the government to devise policies on vagueness and uncertainties in the domestic and overseas economic and business environments so that companies can conduct investment with confidence.

In this paper, DEA analysis is employed to compare and evaluate the relative efficiency of a business intelligence (BI) system among five industrial groups such as IT and financial services, electricity and electronics, energy and chemistry, automotive and heavy machinery, and food and apparel. Especially, this study has analyzed the improving tendency of relative efficiency of the industrial groups since they adopted the BI System using Time-Window Analysis. The research findings show that the energy and chemical industry group tends to be remarkably more efficient than the other groups and the electrical and electronic industry turns out to gradually improve their efficiency since the adoption of the BI system.

2002년도 전력소비량은 2,785억kW로서 작년보다 $8.0\%$ 증가하였으며, 12월중 소비량은 248억kW($8.2\%$증가)로 월간 최대를 기록하였다. 이처럼 전력수요가 크게 증가한 것은 8, 9월중 많은 강우와 저기온 영향으로 냉방수요 증가가 둔화되었음에도 불구하고, 10월부터 일찍 시작된 한파의 영향으로 난방전력 수요가 크게 증가한 때문으로 판단된다. $\divideontimes$겨울철 난방전력 민감도 조사에 의하면 총난방전력수요는 665만kW이며, 겨울철 기온이 $1^{\circ}C$하락함에 따라 31만kW의 난방전력이 증가하는 것으로 나타났다. 2002년도 용도별 소비량은 주택용이 $11.8\%$의 높은 증가율을 보였는데 이는 심야전력($24.9\%$ 증가)을 비롯한 난방전력의 수요가 증가한 때문이다. 또한 일반용($9.1\%$ 증가) 및 교육용($11.9\%$ 증가)도 건실한 증가율을 나타냈다. 한편, 산업용전력은 반도체, 기계장비 및 자동차업종 등 수출주도형 업종의 소비량은 높았으나, 소비 비중이 높은 화학제품 및 섬유업종의 전력소비 둔화로 평균증가율보다 낮은 $6.4\%$ 증가에 그쳤다. 그러나 전체 전력소비량에서 차지하는 비중은 $54.3\%$(1,512억kW)로 여전히 제일 높았다. 지역별로는 수도권이 1,049억kWh를 소비하여 전체의 $37.7\%$ 부산$\cdot$경남은 532억kWh로서 $19.1\%$를 점유하였다.

So far, the phenomenon of "electrification" has been deepened in Korean industry and especially direct heating energy which accounted for 44.0%(2010) of total energy consumed in Korean manufacturing has been significantly electrified. This paper decomposed electricity consumption for direct heating in Korean manufacturing from 1992 to 2012 using LMDI(Log Mean Divisia Index). This paper includes 4 different factors such as electricity proportion effect, direct heating proportion effect, energy intensity effect and added value effect. And this paper compared the consumption pattern by business type. As results, electricity proportion effect had contributed the most to the increase of electricity consumption for direct heating in Korean manufacturing. And Petrol-Chemical and Iron & Steel had the most electrification of direct heating.
