The era of today's day is that the era of the black gold age is now approaching the era of the blue gold age. As the importance of water increases, support and policies for the water industry are presented. The water industry is a public service industry but it faces the problem for unbalanced supply between users. One of solutions for solving the problem at hand is the privatization of the public service and it is the most sensitive and focused subject to the issue. Korea is also coming up for the privatization of the water industry. So, one of the privatization operations based on the privatization of the current waterworks law is management contract by the specialized organization and it is in progress to enhance the efficiency of public services. Therefore, this study aims at finding out the local water supply services' efficiency by K-Water using DEA(Data Envelopment Analysis), and productivity analysis by malmquist index on 18 organizations of the implementation of local water supply management contract using the date from 2012 to 2014. According to the result of the DEA, 10 of the 18 organizations were the most efficient during 3 years and malmquist index for analysing the productivity was decreasing. That is because of the leakage ratio and utilization ratio of the raw water and both of them are significant to productivity. As a result, this study differs from the previous studies by analysing efficiency and productivity using DEA and malmquist index to the solution for the problem faced by current water industry.

This study aims to measure the efficiency and productivity change of 30 domestic construction companies from 2010 to 2018 using data envelopment analysis(DEA) and Malmquist productivity index (MI). In particular, we used the number of employees, capital stock, and non-current assets as input variables, and sales and net income as ouput variables for the analysis. The dataset used for the analysis of efficiency and productivity changes is the employee profile and financial statements for the companies from 2010 to 2018. We found that the MI of the 30 companies is greater than one since 2013. This is because many years of TEC (Technical Efficiency Change) is greater than 1, which means that the productivity index increases as the TEC increases. In addition, the MI value was less than 1, which lowered the productivity of construction firms in 2018. The results of the study may help decision makers to find effective future management plans by analyzing the internal and external factors.

This paper uses MPI (Malmquist Production Index) method to provide basic information and policy direction derived to improve the productivity. This can identify whether or not the railroad service have excellent services, if there are structural problem, in which sector is experiencing a degree of productivity, in which sector should be set targets to some degree. According to the result, the productivity of Korea railway lines is measured 1.1 both publicity and profitability aspects. Changes in production technology were the most important causes. Strategic planning should consider to increase the productivity such as modernization of facilities and equipment, cost savings, and increase in productivity of employee and rail cars.

Recently there has been insignificant growth in the Korean construction management (CM) market, in comparison to the previous year. However, despite stagnation or even decreasing growth trends, the number of domestic companies participating in the CM market has increased rapidly. As follows, market movements of CM despite trending in stagnant growth or decrease, the market has been increasing firms which entry the market. The reasons for such dynamic change must be examined first, in order to facilitate analysis of its competitive structure. This study aims to examine the market competition structure and analyze the reason for proliferation of companies in the sick CM market. This study employs market concentration ratio and DEA-based Malmquist productivity indices to analyze the competitive structure of the CM market. Results reveal that the CM market has been monopolized by a few companies, but this is gradually changing. In addition, these companies were not productive, but there has been a gradual increase in the productivity index. Therefore, this study, which provides the direction index of the CM market, has implications for all major stakeholders in this market.

To increase the productivity and efficiency of public enterprises, privatization has been carried out in a number of different ways. However, the change in productivity and efficiency of privatization have not been validated. Therefore, it is important to investigate the change in productivity and efficiency of privatization. In this study, the impact of privatization was analyzed using the indices of Malmquist analysis and DEA. According to the case studies in Korean privatization, there is no change in efficiency due to privatization. On the other hand, privatization influences the productivity of privatization. These results suggest that the purpose of privatization should be clarified before privatization

In this study, a comparison has been made among the countries regarding recent ICT practices being performed based on the measures of relative efficiency and productivity growth that use multiple inputs and outputs. Efficiency measures a country's ICT performance relative to a benchmark at a given point of time and productivity measures a country's performance over a period of time. An output-oriented Data Envelopment Analysis and Malmquist Index has been used for comparison among 28 countries over the period 2008-2011 by incorporating 9 variables. The empirical findings disclose gross inefficiencies in national ICT practices, which show that there is room for enhancing output gains through increased efficiency in their operations. In addition, 13 countries have performed better than others in total factor productivity mainly because of their improvement in the underlying technological progress in ICT. For those technically inefficient countries, however, technical inefficiency may hamper the growth of total factor productivity of ICT practices.

South Korea's economic growth was rapid, It was occasioned the concentration of resources in the metropolitan area. On the other hand, the province has a narrow economic base compared to the metropolitan area, and the underpopulation have been identified. Thus, The government announced the 'National balanced development law' in 2004 to reduce the problem of regional imbalances. The study collected data on 95 of relocated public institutions, and unlike previous studies, Mamquist analysis was used to compare the productivity before and after each public institutions' s relocation. The study focused on how the relocation of public institutions affected the productivity of public institutions through Malmquist Analysis. The results of the analysis show that productivity is declining after most public institutions have moved. And two independent samples T-test result, respective yearly average is nonsignificant.

This study analyzed the index change in efficiency and productivity for the tax reorganization project of the regional headquarters of Korea Asset Management Corporation using panel data for 3 years from 2017 to 2019 using the DEA-Malmquist analysis model. According to the DEA analysis result, the average of the efficiency by the CCR model of the regional headquarters tax reorganization project of the Korea Asset Management Corporation was 0.671 in 2017, 0.772 in 2018, and 0.699 in 2019, and the average of the efficiency by the BCC model was 0.798 in 2017, 0.851 in 2018 and 0.771 in 2019. As a result of analyzing the Malmquist productivity index, the time series average productivity index MPI increased by 4.5%. These results appear to be attributable to the increase in technological efficiency, technological change, and scale-efficiency change rather than the decrease in net efficiency change. Looking at the change in MPI by year, it decreased by 14.6% in 2017-2018, but increased significantly to 27.8% in 2018-2019. Through the results of DEA analysis of specific tax projects of public corporations, each regional headquarters of Korea Asset Management Corporation will be able to contribute to reinforcing business capabilities through mutual benchmarking.
