This paper estimates the relative efficiency of 29 university libraries in Seoul by data envelopment analysis. We employed library space, staff and book collection as inputs, and book circulation and reader visits as outputs. The result shows that average efficiency score is 0.5248 and only 3 libraries are efficient. Inefficiency is estimated to be 47.52%. Reorganization may be necessary in order to achieve greater efficiency.

This study analyzed collaborative R&D projects funded by the Korean government from 2013-2015. For this analysis, input and output variables of projects were considered, and a combination of those variables was itemized. The output-oriented variable return to scale (VRS) model extended from the DEA methodology was adopted to evaluate the cooperation efficiency of the types of R&D collaboration, which were classified according to the project leader's organizations. In addition, hierarchical cluster analysis was conducted using the efficiency results of the scientific, technical, and economical outcome models. The results showed that cooperation efficiency between large companies and public research institutions was relatively high. Conversely, cooperation among medium-sized companies, small businesses and universities was particularly inefficient. The clustering results demonstrated the various strengths and weaknesses of the types depending on publications, patents, technical loyalties and the number of commercialization. In conclusion, this study suggests differentiated investment portfolios and strategies based on the efficiency results of diverse cooperation types among industries, universities and public research institutions.

This study estimates the productivity change of pharmaceutical industry and decompose the change into technical efficiency change and technological change to explore ways to improve the productive efficiency. Unlike most previous studies, this study employs the non-radial and non-oriented slacks-based Malmquist productivity index which can deals directly with the input excesses and output shortfalls. In addition a smoothed bootstrap method is applied to estimate statistical confidence intervals for the Malmquist Index and its components. For the empirical analysis a balanced panel data set is constructed covering ten years over the period from 2005 to 2014. The input variables used in this study are number of workers, tangible assets and major production cost. The gross production is selected as a main output variable. The empirical results suggest that the productivity of pharmaceutical industry has decreased due mainly to decline in the technological progress rather than improvements in technical efficiency. An analysis result shows that the scale efficiency outweighs the pure efficiency in determining the technical efficiency of pharmaceutical industry. Therefore, in order to enhance the competitiveness of domestic pharmaceutical industry, it is important to continue supporting policies to promote the technology innovation capability through efficient R&D investment and industry reform strategy.

We have analyzed technology transfer and commercialization process and factors affecting the outcomes of technology commercialization of public research institutes in Korea. A technology commercialization process model was presented as an input, intermediate outcomes/capabilities, output (outcome) structure using the structural equation model. Input variables include R&D input, technology commercialization strategy/support, collaboration, social capital. The model also includes R&D capabilities and technology commercialization performance as intermediate variable and output variable respectively. The technology commercialization performance was measured as the number of technology transfer and spin-off. We conducted survey and 88 institutes responded. Empirical results show that R&D input influence R&D capabilities and R&D capabilities influence the output of technology transfer and commercialization. Collaboration activities and social capital also appear to have a positive effect on the output. However, the effect of strategy and support on the output appear to be not statistically significant.

경영성과(經營成果)의 평가지표(評價指漂)는 개별조직의 목표와 제약환경, 즉 이용가능한 자원량과 개별적 특수요인 등을 고려하여 설정하여야 하며, 산업내의 특성과 동질적 비교집단을 이해함으로써 조직의 성과와 직접적으로 연결될 수 있어야 한다. 또한 조직의 평가는 부분적(部分的)인 효율성(效率性)에 편중되지 않고 투입과 산출간의 유기적인 관계를 총체적인 관점에서 분석함으로써 종합적(綜合的) 효율성(效率性)에 그 촛점이 두어져야 한다. 이러한 문제의 인식에 바탕을 두어 본 연구에서는 Charnes, Cooper와 Rhodes(1978)에 의해 처음 개발되어 주로 비영리기관의 경영성과의 평가에 많이 사용하여 온 DEA(Data Envelopment Analysis)기법을 이용하여 금융기관(金融機關)의 효율성(效率性)을 평가(評價)한다. 금융기관은 다양한 투입요소를 사용하여 다양한 서비스 상품을 제공하는 조직이기 때문에, 또 재무비율을 이용한 기존의 평가나 통계적 생산함수의 추정에 의한 평가방법은 단순히 과거의 실적을 평가하는 데 그치게 되고 객관성이 결여되기 쉽기 때문에 조직의 미래운영방향의 설정에 도움이 되지 못한다는 단점을 가지고 있다. 그러나, DEA은 다수의 투입과 산출요소를 요구하는 경우에 적합하게 설계된 분석방법이므로 금융기관의 성과분석에 적절하게 이용될 수 있다. 본 연구에서는 먼저 금융기관(金融機關)의 효율성(效率性)을 평가(評價)하는 기존의 방법을 간략하게 검토한 다음, DEA에 관한 이론적 기초와 그 특성을 검토한다. 실증분석에서는 여 수신업무(與 受信業務)를 수행하고 있는 국내금융기관들 중에서 자료의 동질성과 표본대상 기업의 수를 고려하여 은행업(銀行業)과 투자금융업(投資金融業)을 선정하고 이들 업종에 속한 37개 회사들에 대한 운영효율성(運營效率性)을 측정한다. 투입요소로 직원의 수와 영업비용을, 그리고 산출요소로 영업수익과 경상이 익을 선정하고, 3년간의 자료를 사용하여 실증분석을 한다. 분석의 결과에 의하면, 18개 전체 은행의 평균적인 효율성의 정도는 가장 효율적인 은행을 기준으로 할 때, 약 85% 수준에 그치고 있어서, 나머지 대부분의 은행들 특히 대규모 시중은행들의 경영상의 개선의 여지가 매우 크다고 할 수 있다. 5대 시중은행들간에는 효율성의 차이가 거의 없는 반면, 지방은행들간에는 매우 큰 차이가 있는 것으로 나타난다. 이는 영업지역의 제한으로 인하여 지역경제 규모가 은행의 수지상황에 결정적인 영향을 미치고 있다는 것을 반영하고 있다. 29개 단자회사를 대상으로 한 투자금융업의 경우에도 은행업의 경우와 동일하게 낮은 효율성과 지역간 격차현상이 나타나고 있다.

This study analyzed convergence status among input technologies used in technology development with Technology I-O analysis. It was another version of industry input-output analysis which is used in technology planning. This case is an analysis of association between technology an product. The subjects of analysis were 401 tasks that applied to '2012 Convergence Technology Development Project for Small and Medium Businesses' promoted by Korea Technology & Information Promotion Agency for Small and Medium Enterprises. The process of analysis is as followed. First step, we made a matrix table as an input of technology input-output analysis. Input was defined by technology and output was defined by the product. Input technology was defined in a 3-digit code under National Science Technology Classification and output products were defined in a 5-digit under National Standard Industry Code. Second, the Spillover ratio among technologies were calculated and was used to make a picture of technology linkage. As a result of analysis, technology spillover of embedded S/W was the highest in IT convergence, mold product in ET convergence, and functional cosmetics development technology in BT convergence. In general, IT convergence had many element technologies with high technology spillover, and ET had a small number of element technologies with high technology spillover. Therefore, investment effect of element technology is expected to be large if investment on element technologies with high technology spillover is important for vitalizing convergence.

본 연구에서는 물이용을 포함한 투입산출모형을 구축하고 식량자급률 증가 시나리오를 이용하여 가상적의 물의 소비량을 시산해 보았다. 이를 위해 산업별 물 이용량 자료를 경제활동의 투입요소로 가정하고 투입 산출계정을 확장하였다. 시나리오는 농산물 수입이 감소(5%, 10%, 20%, 40%)함에 따라 및 국내 농산물의 최종소비가 증가하는 방식이다. 분석결과, 국내 농산물 소비가 증가함에 따라 농업부문 생산활동에 필요한 잠재적인 물 소비는 8.3%(3.8억$m^3$)~66.5%(30억$m^3$)로 증가하였다. 또한 순 가상수 유출량(수출-수입)은 시나리오별로 약 -24억$m^3$(SCE1)~-9.8억$m^3$(SCE4)로 나타났다. 이러한 결과는 농업생산이 물 집약적 산업으로 여타 산업과 비교해 물 이용량이 크고, 수출기반 산업이 아닌 국내 소비형 산업의 특성이 반영되었기 때문으로 판단된다. 한편으로 국내 농업의 활성화는 식량자급률 증가에도 기여할 것으로 기대된다. 본 연구의 결과는 국내 식량자급률 증가를 위해서 농업용수 등 수자원의 지속적 확보가 필요함을 시사한다.

This study aims to analyze the convergence change of smart city industries in Korea. Industries of Smart city can be defined ICTs and Knowledge embedded construction industry. The input output model and structural path analysis have been done using the input output tables published by Bank of Korea in 1980 and 2014. GDP deflator was applied to the input output tables. 403 industries were reclassified into 27 industries and 8 industries categories: Agriculture and Mining(AM), Non-IT Manufacture(NITM), IT Manufacture(ITM), Energy Supply(EnS), Construction as smart city(C), IT Service(ITS), Knowledge Service(KS), Etc. Service(EtS). The results are as follows; First, the input output coefficient analysis showed that The information and communication service industry(ITS) and the energy supply industry(EnS) have increased input to the construction industry(C). On the other hands, knowledge service industry(KS) and etc. service industries(EtS) decreased. Second, the multiplier analysis revealed that construction industry(C) led by smart city had a great influence on ITS, EnS, ITM and NITM directly and indirectly. Furthermore, The IT industry had the biggest change from 1980 to 2014. Third, the smart city industry has created a new convergence of 117, and it has been leading to segmentation of the structure. Change of convergence has been proceeding mainly in the ITS and EnS, NITM, ITM industries.

In Korea, the term 'public library service population' is applied in various situations without academic discourse. This study analyzed concepts and applications of the term with literary reviews and case studies in United States, Australia, Japan, and Korea. And also this study redefined concepts and suggested new measurements of 'design population' and 'service population.' The former is the population who lives in area where public library can serve, and only demographic characteristics can be identified. It can be calculated based on the population of administrative district. In case of urban areas with a population of more than 100,000, it can be calculated the population within a radius of 2km from library. In areas with a population of less than 100,000 it can be calculated based on the population of Eup, Myeon, and Dong. In both cases the estimated population up to the library's opening year is added. Service population is used for the planning, evaluating, and promoting library services, and it can be defined as the actual users or estimated population determined by the input resources of the public libraries. It can be calculated by the number of enrolled members, or service participants, or target populations according to the size of input resources. The advantages of the proposal in this study are enabling efficient facility placement or resource inputs in public libraries and enhancing reliability of measuring output versus input. In addition, this study proposed to delete for paragraph 1 of Article 3 of the Library Act to avoid confusion.
