Korea's R&D investment has significantly increased in recent years and the quantitative outputs such as number of papers and patents have also increased with the investment. However, the quality of R&D outputs has not been fully addressed. In particular, quality of technical performance, such as the quality of patents, has attracted little attention. In this paper, a Data Envelopment Analysis (DEA) method was used to construct models for efficiency analysis of R&D investment, focused on quality of technical performance. Indices were proposed to analyze the quantitative and qualitative efficiencies of R&D investment. In order to effectively analyze R&D efficiencies, the measurement units of the input and output variables were standardized. Based on cases of livestock quarantine R&D projects of Korea, the quantitative and qualitative efficiencies of national R&D projects were analyzed and factors that would influence R&D efficiencies were identified. This paper suggests that both quantitative and qualitative efficiencies should be considered when measuring R&D efficiency. Also, it is recommended to carefully consider the characteristics of R&D projects during project selection stage.

This research aims to propose model for measuring the efficiency of R&D organizations by using Data Envelopment Analysis. In existing research about using Data Envelopment Analysis, the types of R&D organizations have not been clarified and the difference between analysis time from measurement time is usually $4{\sim}5$ years. This research divides R&D organizations into three types and provides proper methods for measuring the efficiency of each R&D organizations.

Based on the characteristics of 'Korean electric power industry R&D programs', this study proposes a new performance evaluation framework where electric power industry related R&D projects are scrutinized. The abovementioned R&D programs have their own goals and especially they emphasize the effectiveness as well as the efficiency of each subordinate R&D project. Hence, in this framework, a performance evaluation procedure is established and then a mathematical model is developed according to the procedure. The model calculates performance evaluation indices for a set of R&D projects integrating the effectiveness with the efficiency of each R&D project. In a case study with an empirical dataset, statistical significance is tested on the integrated performance evaluation indices of R&D projects regarding organizational types and program categories considered.

In this study, we conducted a comparative analysis of R&D investment efficiency and operational efficiency of IT firms using Data Envelopment Analysis (DEA). We categorized thirteen sample firms into two groups-IT manufacturing and IT service-after an extensive literature review on IT industry classification. We adopted an output-oriented two-stage DEA model suggested by Banker et al. (1984) with total asset and R&D investment as input variables. Then, we constructed investment efficiency and operational efficiency by using Return on Equity (ROE) and Return on Asset (ROA) as intervening variables and operating income and Earnings Per Share (EPS) as output variables. The outcome of the analysis is summarized as follows. First of all, IT manufacturing firms were more efficient (57% on average) than IT service firms. To be specific, IT service firms showed decreasing returns to scale (DRS) with diseconomy of scale. In contrast, IT service firms showed higher operational efficiency (81.5% on average) than IT manufacturing firms. Also, we conducted a Mann-Whitney U test to compare the output of IT service firms and IT manufacturing firms. Lastly, we found a negative correlation ($R^2$ = -.754) between R&D investment efficiency and operational efficiency which infers the trade-off between two constructs

This paper measures and compares the efficiency of national health technology R&D programs focused on translational research program increasing importance using data envelopment analysis (DEA). Three input variables and three output variables are selected for DEA. Inputs are funds, researchers, and project period and outputs are SCI (E) papers, applied and granted patents, and impact factor. This study uses a three-stage approach. In the first stage, output-based DEA model is applied to evaluate the efficiency of decision making unit (DMU). In the second stage, based on efficiency scores of target diseases high-efficiency group and low-efficiency group are classified. And then strategic portfolio matrix of translational research program is composed of four dimensions combining research types. Mann-Whitney U test is then run to compare average efficiency scores among four groups. In the final stage, Tobit regression model is used to estimate factors likely to influence the efficiency. The results are expected to provide policy implications for effectively establishing investment strategy and managing performance of R&D program.

In this paper, we propose an approach to evaluating the performance of the national R&D investment in IT(Information Technology) areas in terms of paper, patent and commercialization, and seeking ways to improve the efficiency of the national R&D investment. This is because the government has focused the national R&D investment on IT areas for some time. For that purpose, we gather data on investments, papers, patents, and commercializations for the government sponsored R&D projects in IT areas through National Science & Technology Information Service. From which, we summarize the investment and performance in terms of papers, patents, and commercializations for each IT area, evaluate efficiency per R&D investment for each IT area, and compare the efficiencies among IT areas. Finally, we drive implications for efficiency enhancement and strategic R&D budget allocation for each IT area.

4차 산업혁명의 핵심 동인으로서 Software(이하 SW)의 중요성이 더욱 커짐에 따라, 정부는 국가 경쟁력 강화를 위해 SW R&D 투자를 늘리고 SW 관련 정책을 지속적으로 수립하고 있다. 하지만 SW 연구개발에 대한 정부의 지속적인 투자에 비해, SW 연구개발 투자성과에 대한 체계적 분석은 부족한 실정이다. 본 연구에서는 Data Envelopment Analysis(DEA) 기법을 이용하여 SW 국가연구개발 사업의 분야별 효율성을 분석하였다. 2008년~2018년까지 정보통신산업진흥원(NIPA)에서 수행된 1,463개 과제정보를 토대로 효율성을 정태적/동태적 관점에서 측정하였다. 정태적 관점의 규모효율성 측정을 통해 비효율성 원인을 규모와 기술문제로 분석하였다. DEA/Window 모형을 이용한 동태적 효율성 분석 결과를 제시하고 효율성-안정성 매트릭스를 이용해 분야별 대응 모델을 제시하였다. 본 연구는 SW 국가연구 개발사업 전체를 대상으로 효율성 분석을 수행했다는 점에 의의가 있으며, 정태적/동태적 효율성 분석결과는 향후 SW 국가연구개발사업 기획 시 기초자료로 활용이 가능할 것으로 기대된다.

High efficiency deep blue and pure white phosphorescent organic light emitting diodes were developed using a new deep blue phosphorescent dopant, tris((3,5-difluoro-4-cyanophenyl)pyridine) iridium (FCNIr). A high quantum efficiency of 9.1 % with a color coordinate of (0.15, 0.16) at 1,000 cd/$m^2$ was obtained in the deep blue device and a high quantum efficiency of 15.2 % with a color coordinate (0.30, 0.32) was obtained in the pure white organic light-emitting diodes. The quantum efficiency of the pure white device is the best quantum efficiency value reported in the pure white device up to now.

본 연구는 1984년부터 패널자료의 확보가 가능한 17개 OECD 국가를 표본으로 하여 R&D 생산성 및 효율성에 대한 실증분석을 통해 비교하고 우리나라의 수준과 특징을 살펴보고자 하였다. 이를 위해 그 성과를 산출(output) 측면과 성과(outcome) 측면으로 구분하고, 맘퀴스트 생산성지수와 자료포락분석방법을 활용하여 R&D경로단계별 생산성 및 효율성과 그 변화추이를 비교분석하였다. 우리나라는 R&D 투자 대비 산출 생산성은 매우 높은 반면, 평균효율성은 매우 낮게 나타났으며, 효율성의 시계열 변화추이를 보면 최초 지수 0.10에서 시작하여 최종 0.83까지 가파르게 상승하면서 주요 선진국들 수준에 도달하였다. R&D 산출 대비 생산성은 매우 낮으며, 통합 프런티어에 대한 효율성은 최초 지수 1.00에서 최종 0.057까지 주요 선진국들 수준으로 가파르게 하락하여 왔다. 그리고 상관분석을 통해 R&D 산출 대비 생산성이 곧 R&D 투자 대비 생산성을 가늠하는 지표가 될 수 있음을 보았다. 본 연구는 우리나라의 R&D 생산성 및 효율성 향상을 위해서는 R&D 투자 및 산출 증대의 노력이상으로 R&D 산출물의 활용 측면이 보다 강화되어야 하고 이를 위해 효과적인 기술확산 체계 구축, 기술금융시장환경 조성 및 사업화에 성공하기까지 실질적인 인큐베이팅 제공 등 전반적인 기술사업화 시스템의 혁신이 주요 과제임을 시사하고 있다.
