Abstract: The limitation of innovation resources is an important factor that restricts the business mode innovation of enterprises. Although resource patching is considered as an effective way to break through the resource limitation of enterprises, the impact mechanism between resource patching and business model innovation is not clear.By introducing improvisational skills as intermediary variable and environmental dynamics as moderating variable, a moderated intermediary effect model is constructed to analyze the impact of resource patching on business model innovation.The results show that: resource patching has a significantly positive impact on improvisational skills and business model innovation,improvisational skills plays an intermediary role between resource patching and business model innovation, environmental dynamics plays a positive regulatory role between improvisational skills and business model innovation, and at the same time regulates the intermediary role between resource patching and business model innovation.Therefore, enterprises should pay attention to the cultivation of “patchwork” thinking, focus on the development of various uses of resources, and carry out creative restructuring; enterprises should further improve their improvisational skills to promote the “creativity” of enterprises.

Key words: business mode innovation, resource patching;improvisational skills , environmental dynamics
