Abstract:Knowledge rigidity has increasingly become a key factor hindering the sustainable survival and development of enterprises. However, little attention has been paid to how to overcome knowledge rigidity. In recent years, scholars have paid attention to the problem of overcoming knowledge rigidity from the perspective of entrepreneurship orientation, but the current theoretical research can not explain the practice well. Therefore, this paper takes 185 high-tech enterprises in the eastern coastal areas of China as samples, and constructs the overcoming mechanism of entrepreneurship orientation to knowledge rigidity from the perspective of environmental dynamics.Entrepreneurship orientation, innovation dimension and risk-taking dimension have significant negative effects on knowledge rigidity, but pro-activeness has positive effect on experience rigidity and negative effect on learning rigidity. Environmental dynamics promotes the overcoming effect of entrepreneurship orientation on knowledge rigidity .
