| Summary: | 碩士 === 銘傳大學 === 企業管理學系 === 107 === As the problem of environmental pollution is getting serious, the issue of environmental protection has increasingly been paid attention. Not only are the regulations established, but also have the environmental protection industry gradually developed. The sample under investigation is 12 Taiwan listed-or-OTC enterprises during the period of the 1st quarter of 2015 to the 3rd quarter of 2018. The methodology consists of data envelopment analysis (DEA) for operating efficiency, Pearson correlation coefficient analysis, independent-sample t tests, one-way ANOVA analysis, and the Tobit regression analysis for investigating possible influential factors on operating efficiency.
The results are as follows. First, the efficiency of the firms in the environmental protection industry is not affected by seasonality. Second, the firms from the category of the environmental protection resources (ER) have better operating efficiency than those in the categories of environmental protection services (ES) and environmental protection equipment (EE). As a result, it suggests that the operation through resource re-utilization can result in better efficiency. Furthermore, the diversification in operation strategy provides higher efficiency than that under a niche mode. Finally, the result of Tobit regression analysis indicates that the factors of the number of board members, the diversification-operation strategy, and the small size in capital have significantly positive effects on operating performance.
