The quality of vertical network relationships is one of the reliable ways for enterprises to acquire resources,and modern enterprises actively utilize vertical network relationships to achieve innovation cooperation at different levels.Using the survey data from 205 companies in Fujian Province,this study examined the impact of vertical network quality and entrepreneurship on enterprise performance and explored the moderating effect of entrepreneurship.The results show that in vertical network relationships,both upstream and downstream network quality have a significant positive impact on enterprise performance,and entrepreneurship also has a significant positive impact on enterprise performance.Moreover,enterprises with higher entrepreneurship enhance the positive impact of upstream network quality on enterprise performance while weakening the positive impact of downstream network quality on enterprise performance.These findings contribute to understanding the construction of network relationship quality in manufacturing enterprises and the complex influence of entrepreneurship in dynamic environments.
