This study explores the positive effects of environmental commitments and green intangible assets on green competitive advantages of companies in Taiwan. The results show that environmental commitments and green intangible assets are positively associated with green competitive advantages. Investments in the environmental commitments and green intangible assets are helpful to businesses for the enhancement of green competitive advantages. Furthermore, this study finds that environmental commitments, green intangible assets, and green competitive advantages of small & medium enterprises (SMEs) are all less than those of large enterprises in Taiwan. Hence, there is the advantage of firm size with respect to environmental commitments, green intangible assets, and green competitive advantages in Taiwan, and it is imperative for SMEs to develop their environmental commitments and green intangible assets to strengthen their green competitive advantages.
