The industrial ecology indicators(IEI) for Yeosu Industrial Park were developed using eco-efficiency indicator(EEI). The key factors for the creation of IEI were two parts. One part is the value of the products which is selected as the total production value, the amount of ethylene production, the amount of light oil production instead of the total sales volume for Yeosu Industrial Park, since the currency exchange and the price of raw materials varied every year. The other part is the environmental burden. The electric consumption, the industrial water consumption, and the amount of discharged waste water are all officially opened to the public, were used in the calculation. Based on the value for the year of 2004, the IEI value for 2006 became worse to 0.954, but, was expected to be 1.153, a 15% improvement, for 2015 if the current EIP project is successfully performed.

1997년 IMF 경제위기 이후 우리나라의 금융산업은 급격한 변화를 겪고 있다. 지난 4년간 은행들을 비롯한 금융기관들이 대형화를 통한 경쟁력 강화를 위해 합병이 실시되었다. 은행합병의 궁극적인 목적은 합병에 의해 규모를 대형화하고 업무범위를 다양화하여 수익규모를 증대시키고 수익원을 다원화하는 한편, 경영자원의 투입과 활용을 효율화하고 시장지배력을 확충하여 경영성과를 제고함으로써 기업가치를 증진시키는데 있다고 할 수 있다. 본 연구에서는 1997년 이후에 본격적으로 이루어진 합병은행들을 대상으로 맘퀴스트 ${\ulcorner}$Malmquist${\lrcorner}$ 총요소생산성(Total Factor Productivity) 지수를 사용하여 그 성과를 측정해 보았다.

In this paper, technology gap between Korea's manufacturing industries compared to technology frontier countries was estimated in order to take into account Korea's status as a technology follower country. Then by using this measure the role of technology gap was investigated in explaining total factor productivity growth of the Korean manufacturing at industry level. The main empirical findings are as follows: First, the conventional factors that were emphasized in the previous literature such as R&D intensity, trade openness and human capital play important role in explaining the growth rate of Korea's total factor productivity. Second, the larger the technology gap between Korea and technology leader country (and the faster the technology growth rate in the leader country), the higher the growth rate of total factor productivity in Korea as well. Third when the technology gap is large, the most efficient way of absorbing higher technology from frontier country seems to be the international trade channel rather than R&D or human capital accumulation.

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.

In this research, the world top steel companies' technical changes were measured by the nonparametric Malmquist index. Steel industry's production frontier which was composed of multiple inputs and multiple outputs was defined by using real data of the companies from 1986 to 1998, and then the variability of technical progress(or regress) was analyzed during that period. The dynamics of individual steel companies\` technical changes, periodical technical changes, and each country's technical chanties were explained. A matrix which was based on technical chanties, technical efficiency changes, and scale efficiency changes was designed to assist to find out current position and In build up future strategies. This research results will be an valuable input to the early stage of formulating competitive strategy because the technical core capability is an important source of the each companies's competitiveness.

This study analyzed the influence of investment and fostering support on gross regional product by utilizing big data using multiple regression analysis. Gross regional product (GRDP) is an index that intensively contains the production scale, expenditure level, income level, and industrial structure of each region, and is an important data used for regional economic analysis and national policy establishment. In order to properly carry out the country's major national tasks, it is necessary to accurately grasp the regional economy, and as a result, interest in regional gross domestic product is rapidly increasing. In particular, foreign investment has a significant impact on the economy of the host country, and many empirical analyzes are being conducted. In this study, correlation analysis and multiple regression analysis were conducted to examine the influence of foreign investment and domestic development support on gross regional product, and as a result, it was concluded that investment and support as a whole had a positive effect on gross regional product.

기존의 연구논문들에서는 1975년부터 1992년 사이의 OECD 국가들에서 집권정부별 국민들이 느끼는 행복감을 알아보기 위한 분석들이 주로 이루어졌다. 이러한 행복감을 알아보는 데에는 특히 인플레이션율과 실업률이 주요 변수로 활용되고 있다. 각국별로 살펴볼 때, 진보정부의 경우에 있어서는 실업률에 더 주안점을 두는 반면에 보수정부는 인플레이션율에 더 민감하게 대처함을 알 수 있었다. 이러한 점들을 살펴보면, OECD 국가들에서 빈곤층은 진보정부를 선호하고 상대적으로 소득수준에서 상위계층은 보수정부를 선호할 것으로 추정된다. 이 논문에서는 한국의 경우 시계열 관계상 진 보정부와 보수정부로 나누지 않고 행복감에 대하여 소비자심리지수를 대용변수로 사 용하였을 경우 경기회복에 따른 산업생산 증가와 이를 위한 정부지출이 중요한 변수 임을 알 수 있었다.

The status of Ppuri industry, including foundry industry was analyzed through statistical surveys over the past 10 years from 2009 to 2018, and summarized for each six Ppuri industries' points of view. Various statistics of Ppuri industry defined by the KSIC (Korean Standard Industry Classification) was obtained, and the status of Ppuri industry was identified through a sample survey of 5,000 companies from more than 30,000 target business companies of Ppuri industry. Throughout the analyzing process, we presented a variety of indicators, such as the number of the Ppuri companies and its ratio, regional distribution through Korean provinces, number of workers, characteristics by age group, sales, profit rates, etc. By devising a comparative method to measure the relative strength of Ppuri industry in Korea, Germany, and Japan, we have presented the competitiveness index change over the 10 years of time. The competitiveness index can be effectively and meaningfully used during various activities of the development of Ppuri industry in the forth coming future. With the current obtained data, we figured out the status of each 6 Ppuri industries, regional distribution, status of workers, sales and profit rates. We also suggested various proposals for strategy and policy making for each sector with urging voluntary response from Ppuri industry.

제조 산업에서 키워드로 많이 다뤄지는 4M데이터(man, method, machine, martial)는 생산에 효율성을 높이기 위한 중요한 요소이다. 규모가 작은 기업일수록 4M관련 데이터 관리가 잘 안되고 있다. 관리를 잘하는 기업이라도 수집하고 저장만 하고 있는 현실이다. 본 논문에서는 수집하고 저장되어 있는 4M데이터를 활용해 생산한 상품에 대한 생산당시 상황을 추적할 수 있는 시스템을 제안한다. 제안한 시스템을 이용해 생산라인의 상황을 한 눈에 파악이 가능하고 주로 문제가 발생하는 공정과 관련 요인 파악을 통해 불량률을 줄이는 연구를 할 수 있다.
