Although much research has been done to investigate the influence of regulatory and customer pressure on green innovations, the existing literature paid little attention to the question of how such pressure motivates organizations to improve their green innovation performance. A conceptual model based on the concept of green organizational responses is developed in this paper. The model is tested using structural equation modeling on a sample of 427 manufacturing organizations in six provinces in central China. The results of modeling show that regulatory and customer pressure promotes green organizational responses and enhances green innovation performance. However, these two forms of pressure are shown to have different impacts on specific organizational responses and different extent of impact on green innovation performance. For example, while regulatory pressure has significant positive impact on training and plays a direct role in green innovation performance, customer pressure has significant positive impact on research and development investments and collaboration networks. These results offer important implications for promoting green innovations in the manufacturing industry.
