碩士 === 中華大學 === 工業管理學系碩士班 === 103 === The purpose of this study is to investigate the 2012-2014 Taiwanese nature gas corporation efficiency and malmquist, selected Taiwanese six listed and six unlisted companies as the object of study. This study adopted the method of input-oriented DEA Slack-based Measure (Slack-based Measure, referred to as SBM) to evaluate the efficiency of each year. The research of financial efficiency used six variables, the input items including “total assets,” “operating costs,” “operating expenses,” and the output items including “operating income,” “earnings per share,” “operating profit”.
