This paper explores the role of multiple stakeholder-driven factors in promoting sustainable technology application in fashion manufacturing enterprises from the perspective of stakeholder theory and analyzes the impact of sustainable technology application on environmental, financial, and competitive performance. Through empirical analysis of survey data from 350 fashion manufacturing enterprises in Quanzhou City, the results reveal that customer pressure, management support, policy support, and competitive pressure significantly and positively influence sustainable technology application in enterprises, while the influence of regulatory pressure is not significant. Furthermore, sustainable technology application has a significant positive impact on the environmental, financial, and competitive performance of enterprises. The research findings provide theoretical insights for successful deployment and implementation of sustainable technology applications in fashion manufacturing enterprises, as well as for government optimization and adjustment of supportive policies.
