The purpose of business strategy is to achieve competitive advantages which includes higher efficiency, better quality, more innovation and faster customer response. In other words, The business strategy is to build unique capability of lower cost and/or differentiation. In production aspect, unique capability means better production power with better performance at 3M(Man, Machine, Material) of input and PQCDSM (Product, Quality, Cost, Delivery, Safety, Moral) from output. The Total Productive management (TPM), a series of improvement activities focused on reduction of equipment loss, is a tool to establish business competitive advantages. In this paper, several domestic companies who won the Japan TPM Award have been studied. It is found that there is a strong cause-effect relationship between TPM and competitive advantages because. 1. TPM can change employees mindset effectively. 2. TPM can upgrade employees capabilities. 3. TPM can lead to excellent productivity.

Given capital market imperfections, an entrepreneur can alleviate financial frictions by creating a pyramidal business group in which a parent firm offers its subsidiary firm internal finance. This endogenous creation of pyramidal business groups can beget asymmetric financial frictions between business-group firms and stand-alone firms. I build a model to show that these asymmetric financial frictions can have sizable effects on resource allocation. On one hand, the financial advantage of pyramidal business groups can foster productive firms by incorporating them as subsidiaries. On the other hand, the asymmetrically large amount of external capital controlled by pyramidal business groups can be expended by unproductive business-group firms and push up the equilibrium price of capital. The model suggests that with fine investor protection or low financial frictions, the benefits of pyramidal business groups can be dominated by their costs because the probability of fostering productive subsidiaries diminishes as the efficiency of external capital markets improves, while the prevalence of pyramidal business groups is not attenuated due to their continuing asymmetric financial advantage.

In this study, we evaluate the efficiency of Construction Industry using Data Envelopment Analysis(DEA). Since the Construction Industry has been traditionally operated through competition, it is important to measure the efficiency. In this paper, we empirically analyze the Efficiency of the 50 Korean Construction Industry. In detail, we used the scale of efficiency in order that efficiency cannot be affected by the total technical efficiency of each company and the scale of DMU by applying CCR or BBC model. Also, we analyzed the changes of measurement DEA model score. we adopted the basic DEA, RTS Region and MPSS(Most Productive Scale Size) method which are combined with efficiency measurement model in order to analyze the operational status. Furthermore, by complementing the shortfalls of the scale efficiency value of the DEA Model, RTS Region Model can be recommended to be appropriate in the evaluation of ideal input/output Quantity. In particular, input variables are total assets, construction capacity, the technical staff and output variables are sales volume, operating income. The result of RTS Region and MPSS shows that 9 DMUs of the efficiency frontier in the Construction Industry are analyzed to be relatively efficient DMUs, and 41 DMUs are analyzed to be inefficient DMUs, and finally inefficient DMUs are separated with Region 1 and Region 6.

Objectives : This study examined relations between investment efficiency and management performance as indexes related to productivity of Korean regional public hospitals. Methods : The analysis data are financial information of Korean regional public hospitals from 2011 to 2014. For the indicators, value added to total assets, value added to productive activity tangible fixed assets, and value added to personnel expenses, operating margin to revenues, net profit to total earnings, and ratio of value added. Results : Significant relevance was not shown among indicators of investment efficiency. However, Significant relevance was shown between value added to personnel expense and productivity per value added. Conclusions : It confirmed that outside support funds like subsidy did not have effect on improving the management performance. Also, it could be known that availability about input of capital and labor was not realized organically.

To evalate the efficiency of public and private hospitals, the author used Data Envelopment Analysis(DEA), a mathematical linear programming method calculating the of ficiency of a unity(DMU: Decision Making Unit) in relation to the other units in analysis. DEA was applied to thirty three (10 public and 23 private) general hospitals wiwith 160 to 299 beds. In respect to productivity, public hospitals appeared to be a little more efficient than private ones, even though it's statisticansignificant. However, the efficiency score for profitability conversed that these contrary results were due to the caring of more medical protection patients in public hospitals, who brought less revenlue to te hospital than other patients. Public hospitals' superiority to private counterparts in productivity, which are aguged mainly based on cared patients, suggests that the former contributes so much positively to social utility. In particular, the fact that public hospitals are caring more medical protection patients, namely the poverty group whom the society should bear a burden of by all means, seems to be desirable in respect of role of publi hospitals.

A prerequisite for making R&D more productive is to able to measure its productivity. Most of the previous studies on this topic have attempted to measure R&D productivity at the firm or industry levels. In this study, however, R&D productivity is measured at the national level to provide R&D policy implications, particularly for Asian countries. Contrary to the previous studies where total factor productivity was adopted, this study employs the data envelopment analysis (DEA) approach to measure R&D productivity. DEA is a multi-factor productivity analysis model for measuring the relative efficiency of each Decision Making Unit (DMU). In addition to the basic DEA model that includes all inputs and outputs, five additional models are constructed by combining single input with all outputs and single output with all inputs in order to measure specialized R&D efficiency. In this study, the twenty-seven countries are classified into four clusters based on the output-specialized R&D efficiency: inventors, merchandisers, academicians, and duds. Then, the characteristics of the Asian countries with respect to R&D efficiency are identified. It is found that Singapore ranks high in total efficiency, and Japan in patent-oriented efficiency. Meanwhile, China, Korea, and Taiwan are found to be relatively inefficient in R&D. We expect that the findings from this study will be able to provide directions for R&D policy-making of the Asian countries.

본 연구는 강처분성의 가변수익규모 및 비방사적 자료포락분석기법을 이용해 조직유형이 다른 도시철도 운영기관인 서울시지하철공사(지방공기업)와 철도청의 수도권 전철부문(정부부처형 공기업) 및 부산교통공단(국가공단)의 연도별 생산적, 기술적 및 배분적 효율성 값을 추정한 다음, 이들 값에서 토빗회귀식의 추정결과를 이용해 조직유형과 궤도가동률과 같은 외부 요인들의 영향을 제함으로써 내부 요인인 생산활동만의 영향이 반영된 순생산적, 순기술적 및 순배분적 효율성 값을 구하였다. 또한 토빗회귀식의 추정결과로부터 세 도시철도 운영기관들의 조직효율성과 연도별 총효율성 값을 구하였다. 이 때 토시철도 운영기관은 노동, 전력, 전동차 및 유지보수와 궤도(또는 자본) 요소를 투입하여 전동차-km를 생산하는 기업형태로 상정되었으며, 분석에는 세 운영기관의 연도별 자료로 구축된 불균형통합자료가 사용되었다. 자료포락분석의 결과 생산적 효율성과 배분적 효율성은 평균적으로 서울시지하철공사가 가장 높은 반면, 기술적 효율성은 철도청의 수도권 전철부문이 가장 높은 것으로 나타났다. 그러나 생산활동만을 대상으로 추정된 순생산적 효율성과 순배분적 효율성은 오히려 부산교통공단이 가장 높은 반면, 순기술적 효율성은 철도청의 수도권 전철부문이 가장 높은 것으로 나타났다. 또한 이러한 순효율성들의 경우 외부 요인들의 영향이 배제됨에 따라 세 운영기관들의 차이는 상당히 감소하는 것으로 나타났다. 한편 조직효율성의 경우 비용을 극소화하는 조직유형은 지방공기업인 서울시지하철공사인 것으로 나타났으며, 이러한 조직효율성과 순생산적 효율성을 합한 총 효율성도 평균적으로 서울시지하철공사가 가장 높은 것으로 나타났다. 이러한 결과들은 도시철도 운영기관들의 경영상태에 대한 공정한 평가를 위해 외부 요인의 영향을 배제하는 방안의 시행과 기존 또는 신설될 도시철도 운영기관의 비용효율성을 제고하기 위해 지방공기업 또는 공단으로의 조직유형 개편의 필요성을 시사하고 있다.
