DEA 모형을 활용한 광주 광산업체 효율성 평가에 관한 연구 = A Study on Evaluating the Efficiency of the Photonics Industry in Gwangju Using a DEA Model

다국어 초록 (Multilingual Abstract)

In this study, we try to evaluate the efficiency of the photonics industry using a data envelopment analysis(DEA) model. We first develope four stage procedures for selecting proper input and output variables which consist of selecting the first candidate variables from literature survey, selecting the second candidate variables through experts` discussion, measuring the partial efficiency of the selected variables based on Tofallis` profiling, and clustering some variables through the rank correlation analysis of partial efficiency proposed by Mm and Kim(1998). With this procedure, we select 4 input variables(capital, number of employee, R&D cost, operating cost) and 2 output variables(sales, growth of sales) and then utilize CCR and BCC model to measure efficiencies of 26 photonics companies in Gwangju. Moreover, we perform the reference group analysis to figure out what causes inefficiencies and to provide the desirable values for input and output variables at which inefficient photonics companies become efficient. Finally, we classify 26 photonics companies into three groups such as optical communications, optical applications, and optical sources, and perform the Kruskal-Wallis test to check if there exist some differences between efficiencies of three groups.
