Although considerable amount of the literature related to examination the link between environmental protection issues and the performance, different results and mixed outputs have been articulated by these studies, and previous research yet to investigate the relationship between multidimensional approach of corporate environmental practices and competitiveness. The purpose of this paper was to disaggregate corporate environmental activities into six dimensions (green practices, employees’ involvements, environmental management systems, organizational practices, strategic planning process and stakeholders’ integration) based on both stakeholders and resource- based view theories, and examine how each dimension would affect competitiveness among manufacturing industries. While all corporate environmental activities were proposed to have positive effects, the results revealed that each dimension has a different effect on competitiveness. Such results may assess the industrial corporation by directing their efforts to specific areas when trying to improve their competitiveness.
