This study estimated and decomposed the productivity changes into technological change and efficiency change components for the photonics industry and examined ways of imporving the productive efficiency. Unlike most previous studies, this study employed a non-oriented Malmquist productivity index, which is a non-radial method and deals directly with the input surpluses and output shortfalls. The empirical results show that the productivity of the photonics industry has increased. The main reason for this is the increase in technical efficiency. In addition, there was a statistically significant difference in the productivity changes according to the firm's geographic location and participation in government support programs. These findings suggest that the government's regional strategic industry promotion policy has contributed to improvements in the productive efficiency of photonics industry. The approach presented in this study could be used as a practical reference guide to help enhance the competitiveness of the photonics industry.

This paper aims to measure and analyze R&D productivities and efficiencies of 17 major OECD countries including Korea over the 1984-2008 period by using the Malmquist Productivity Index and Data Envelopment Analysis, classifying R&D performance into an output and outcome aspects. It also searches the Korea's current status and characteristics in each R&D stage to enhance Total Factor Productivity (TFP) compared with other developed countries. Our major findings are the followings: (i) Korea's productivity index of R&D input vis-a-vis R&D output is very high (13.39% annual growth rate) compared with those of major advanced countries, whereas the annual average of efficiency index is very low (0.33), i.e. Korea's technical efficiency index has risen to 0.83 at the last time series started at 0.10 point and come up to the level of major advanced countries. (ii) the Korea's productivity index of R&D output vis-a-vis R&D outcome is very low (14.02% annual reduction rate) compared with those of major advanced countries, whereas the annual average of efficiency index is very high (0.22), i.e. Korea's integrated frontier technical efficiency index has dropped to 0.057 at the last time series started at 1.00 point and coming up to the level of major advanced countries. (iii) The productivity of R&D input vis-a-vis R&D outcome is positively correlated with that of R&D output vis-a-vis R&D outcome and the growth of R&D input factors. In a nutshell, it implicates that the effort to take advantage of R&D outputs, namely establishing the diffusion and commercialization system of technical knowledge to the level of developed countries, should be strengthened over that on the growth of R&D investment and output for enhancing R&D productivity and efficiency in Korea.

This research explores the efficiency of social welfare expenditure in Korea by analyzing marginal productivity, scale economies, and elasticity of substitution that could be obtainable from a production function. By virtue of VES production function, such productive indicators are easily identified. If once the efficiency is revealed in the production process, it brings to a positive impact to increase the level of income. Empirical evidences are shown that the public expenditure is operated systematically in comparing with the private one. This is mainly due to the fact that the system of the public sector is well-established. It implies that an operational system for the private sector ought to be built up in a short period of time. Otherwise, increasing in expenditure by a private sector would not be helpful to improve efficiency in the production side. Accordingly, level of income.

The Mutual Financial Cooperatives(MFCs) in Korea need to make efforts to increase efficiency and productivity in order to secure stable and sustainable growth and competitiveness. Therefore, this study analyzes the efficiency and productivity of MFCs from 2012 to 2018 and suggests some implications. The methodology employed is a Dynamic-Network Slacks-Based Measure(DNSBM) Model. The findings from an empirical study include that first, on average efficiency scores of the institutions, NH(0.225) showed the highest overall efficiency, and followed by SH(0.128) and MG(0.126). After 2015, most of the MFCs' efficiency scores had risen until to 2018. Second, in divisional analysis, the inefficiency in creating the high profitability-stage had been greater than establishing-funds-stage. Third, in projection analysis of Division 2, the inefficiency of the output factors such as interest income and operating income was severe. Fourth, the results from the Malmquist Productivity Index analysis of Division 1 of the fist-stage illustrate that all three MFCs showed minus catch-up effects. Also, a soundness from reducing bad loans and expansion of loans in combination with generating various ways of creating profits besides the interest income is urgently needed for Korean MFCs.

This paper aims at analysing the effects of venture business finance supporting programs on efficiency and productivity of the venture firms, on the basis of the data envelope analysis (DEA) using data of 406 firms in the 2013 Venture Business Detailed Survey of Small and Medium Business Administration. The conclusions are summarized as follows. First of all, the efficiency of government finance supported venture firms is higher than that other venture firms. The increase of productivity in venture firms enjoying government supporting programs is higher than that in venture business without government supporting programs, especially in the technical progress rather than in efficiency improvement. Also the R&D supporting programs for venture firms lead to an increase in productivity. Taking the above results into consideration, government's venture supporting programs are evaluated to be effective in terms of an increase of productivity and the proper scope for fragile venture firms.

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.

The purpose of this study is to evaluate the performance efficiency and productivity change of the regional public hospital in Korea. We use DEA(Data Envelopment Analysis) for CCR, BCC model, and MPI(Malmquist Productivity Index). DEA is a useful nonparametric technique for measurement of efficiency of a DMU(Decision Making Unit) and MPI is a evaluation method to measure DMU's productivity change. We utilize 34 regional public hospital's time-series data over 6 years from 2003 to 2008.The results of this study were as follows. First, technical efficiency(TE) shows that approximately 3.6% of inefficiency exists on the regional public hospitals and it reveals that the cause for technical inefficiency is due to scale inefficiency. Second, MPI's results show that regional public hospital made effort to improve total factor productivity change to raise technical efficiency. In order to raise efficiency, the regional public hospitals should deploy internal innovation and the government should support welfare policies.

본(本) 연구(硏究) 1960년대말 이후 1980년대초 기간중에 민영화(民營化)된 공기업(公企業)에 대하여 민영화(民營化)가 개별기업(個別企業)의 생산효율성(生産效率性)에 미친 효과를 회귀분석모형(回歸分析模型)에 의하여 추정하고, 추정결과를 토대로 향후 정부의 바람직한 민영화정책의 방향을 제시하고자 한다. 본(本) 연구(硏究)의 분석결과(分析結果), 공기업민영화(公企業民營化)는 대한통운, 대한항공, 대한재보험, 그리고 대한석유공사의 경우 개별기업의 생산효율성(生産效率性) 증진(增進)에 긍정적인 효과를 미쳤으나, 5대(大) 시중은행(市中銀行)의 경우 공기업민영화(公企業民營化)가 기업(企業)의 생산효율성(生産效率性) 제고에 미친 효과가 미미하여 통계적 신뢰성이 낮게 나타나거나 부정적(否定的)인 효과(效果)가 추정(推定)되었다. 이러한 분석결과(分析結果)에 근거할 때, 기업민영화(公企業民營化)가 항상 기업(企業)의 생산효율성(生産效率性) 증가(增加)에 기여할 것이라는 일반적인 믿음은 현실적안 근거가 부족하며, 일정한 조건이 충족되어야 그러한 믿음이 현실화될 수 있음을 알 수 있다. 민영화(民營化)가 바람직한 정책효과(政策效果)를 나타내기 위해서는 공기업민영화시(公企業民營化時) 기업소유권(企業所有權)의 민간이전뿐만 아니라 실질적인 경영권(經營權)의 이전이 수반되어야 하며, 민영화(民營化)와 더불어 정부(政府)의 각종 규제(規制)와 간섭(干涉)이 배제되어야 한다.
