  • This paper studies the efficiency of public sector confronting with increasing oil price, economy crisis and energy-environment problems. In consideration that efficiency of national R&D program has been subjectively evaluated, this paper focuses objective validity by relative efficiency through a comparison among R&D programs in Korea. To implement this study, data published in national reports on R&D programs is used and analyzing method is induced by related books and theories. At the result of Data Envelopment Analysis on the collected data, this paper suggests the way to enhance the efficiency of nuclear R&D program. This study is the first on efficiency of national R&D programs applied DEA methods and is expected to contribute exploring the more efficient way of program management if more sophisticated DEA could be developed and applied.

  • This paper empirically analyzed the factors of operational efficiency after the quasi-public bus operating system in Busan Metropolitan City. DEA analysis result, for CRS the annual efficiency in 2010 of bus routes that can be transferred to subway lines 1 was the highest. The annual efficiency of bus routes that can be transferred to subway lines 2 shows the largest annual average of 0.923 in 2016 under the CRS average gradually improved over the year. Annual efficiency of subway lines No. 3 and transferable bus routes gradually improved from 2009 to 2015, but declined again in 2016. Among 536 routes for four years on 134 routes per year, 205 routes were found to be inefficient. In order to increase efficiency of the 205 routes, it is suggested that the number of routes should be reduced. In addition, the analysis results on DEA using the Tobit calibration, the most significant factors affecting the operational efficiency index were the time taken, followed by the number of passengers and the number of passengers transferred.

  • The purpose of this study is to analyze the efficiency and productivity of technological innovation activities of companies certified as innovative pharmaceutical companies by the government to diagnose their competitiveness and derive measures to strengthen them. This study collected pharmaceutical input (R&D expenditures and number of employees) and output (sale, operating profit and patent) data between 2017 and 2019 for 38 innovative pharmaceutical companies. This study analyzed them using the data envelopment analysis (DEA) method, Tobit model and the Malmquist Productivity Index (MPI). First, the DEA result of the innovative pharmaceutical companies show that between the value of the CCR model of the scale efficiency and the value of the BCC model to diagnose the internal operation efficiency is differences. Second, efficiency does not differ between corporate characteristics. Third, Tobit model shows that number of patents held have positive effects on efficiency. Forth, overall MPI is 0.89. This can be interpreted as the rate of TECI decreased 3%p and TCI has increased 4%p. The results of this study can be used as decision-making data for response strategies to improve efficiency by identifying the cause of inefficiency and presenting target values.

  • As an alternative to solving social problems, social economic actors are attracting attention as an important alternative. SPC is a private program that pays incentives according to the social performance measured by monetary value. This study measured efficiency by applying DEA to social enterprises that participated in the SPC program and analyzed the factors affecting efficiency through tobit regression. As a result of DEA analysis, it was found that 21% of social enterprises participating in SPC were efficient, but 66% needed to improve their efficiency. In the Tobit regression analysis, the efficiency was relatively low in the case of manufacturing sector, and when the square term of sales is included, the efficiency decreases as sales increase. Through this, it was estimated that external support is needed at a low level sales before crossing the critical point, and that the efficiency of social value creation increases when it grows above a certain level. Moreover, it is significant in that it combines the variables used in the analysis of traditional industrial efficiency while conducting efficiency analysis focusing on the social performance by monetary value, which is considered the most important achievement of social enterprises. It is believed that it will contribute to research related to the environment creation and the requirements of each field in creating social values for social enterprises in the future.

  • This study compares and analyzes the efficiency of R&D activities of technology-innovative small and medium-sized enterprises(SMEs) between industries and proposes ways to improve efficiency. The research samples are 6,708 technology-innovative SMEs, which have received a guarantee by the KIBO from 2008 to 2011. Input variables are the level of R&D personnel, R&D investment, and output variables are patent applications, prototype. Efficiency is measured by the DEA model, and indirect comparisons that are individually measured by industry are performed. As a result of the analysis, the CCR for determining the optimal returns to scale is 0.19, the BCC for determining the optimal input distribution is 0.70, and the SE for determining the optimal output is 0.30. By industry type, the medium and low-tech industries have high CCR and BCC, while the high-end and high-tech industries have high SE. R&D activities need to be operated on an optimal scale through managing R&D performance because there is the inefficiency of scale across the industry. The contribution of the study is to analyze the R&D efficiency of each industry of technology-innovative SMEs by the technology evaluation data of the KIBO.

  • Purposes of this study are to find difference in efficiency, productivity change and determinants on efficiency of life insurance industry between pre and post-execution of capital market law on the basis of pre(2005-2008) and post-execution(2009-2012) data. Main results of this research are as follows. First, there was no significant difference of mean value for efficiency between pre and post execution of capital market law. Second, difference of mean value for malmquist index between pre and post execution of capital market law was statistically significant at 5% level. This imply increase in productivity for post-execution of capital market law. Third, one of the important determinant for efficiency was the weight of life planner in both pre and post-execution of capital market law. The weight of life planner had significant positive effect on efficiency.

  • This study aims to analyze the relation between management efficiency and financial performance in public institutions. Based on 135 public institutions published in public business information system from 2017 to 2020, Data Envelopment Analysis(DEA) for estimating management efficiency was performed. This study analyzed the relationship between DEA and financial performance included ROA and ROS using multi-regression analysis. The results of this study are as follows; We find that there is significant positive relation between management efficiency and ROA. We also find this significant relation in model with ROS. This finding implies that management efficiency a factor that improve financial performance in public institutions. The results of this study can provide an important empirical evidence for evaluating the strategy of governance to improve financial performance by enhancing management efficiency.

  • 정보화 연수가 ICT활용수업과 맞물려 많은 예산을 들여 교사들의 방학을 차지하고 있지만 정작 일선현장에서는 연수 이수 후에 수료증 말고는 크게 기여를 못하고 있다. 영어연수처럼 분명 수준차가 있는데도 이를 무시하고, 교사가 원하는 연수 내용보다는 개설한 연수에 학교별 인원을 할당하는 식으로는 절대로 연수의 효율성을 기대할 수 없고, 교실의 ICT활용수업도 기대할 수 없다. 본 연구는 연수의 효율성 극대화를 위한 방안의 하나로 컴퓨터관련 자격증과 정보화 연수의 내용을 연계하여 가능한 정보화 연수를 컴퓨터관련 자격증 수강, 응시, 취득으로 유인하여 효율성을 기하고자 하였다. 정보화 연수의 문제점을 지적하고 그 해결책에 대해서도 설문결과를 통하여 제시하였다.
