DEA Window 분석을 이용한 국내 온라인 게임 기업의 운영 효율성 평가

This paper measures the operational efficiency of domestic online game companies and analyze its trends and patternsby using data envelopment analysis (DEA). DEA is a non-parametric approach to measuring the relative efficiencyof decision-making units (DMUs) with multiple inputs and outputs. 14 online game companies are selected as DMUsand three inputs (number of employees, capital and asset) and three outputs (sales, operating profit and net profit)are selected as DEA variables. First, the output-oriented BCC model and super-efficiency model are employed to measurethe static operational efficiency of the online game companies from 2003 to 2012. We also conduct the dynamicanalysis with DEA window model to capture the trends of their operational efficiency influenced by internal and externalenvironmental changes. The results are expected to provide fruitful implications for strategic decision making of onlinegame companies and policy making for the online game industry.
