Why go green?: The effects of internationalization, path-dependency, and environmental uncertainty

The purpose of this study aims to depict the relationships between the degree of internationalization, industry pressure, firm resource and the adoption of voluntary environmental program (ISO 14001). We employed a data set composed of 357 firm-year observing points from the sampling listed firms in Taiwan with the period from 2001 to 2008. Empirical results suggest that a firm´s degree of internationalization have a significant impact on the certification of ISO 14001. Notably, both significantly positive and negative impact on the certification of ISO 14001 is due to different measurement of internationalization. A positive relationship between the experience of ISO 9000 and ISO 14001, and a negative relationship between environmental uncertainty and ISO 14001 are also confirmed in this study.
