Abstract: With the overloading development of renewable resources and exploration of non-renewable resources, the environment carrying capacity is close to the upper limit. When facing the increasingly severe environmental problems, green management has become the key to the sustainable development of corporates. Based on the organizational identity theory and resource-based view, the study regards manufacturing corporates in Beijing-Tianjin-Hebei region as the research object and uses hierarchical regression method to explore the influence of both the internal factors (organizational environmental identity and green product innovation) and external factor (Business dynamic environment) on green competitive advantages, and clarify the effect of organizational environmental identity on green product innovation. The result shows that organizational environmental identity positively influences corporate competitive advantages, and green product innovation plays mediation role between organizational environmental identity and green competitive advantages, and business dynamic environment positively moderates the relationship between green product innovation and green competitive advantages.
