Abstract: Customer-led front desk service strategy and product-led back office service strategy are important ways to transform and upgrade manufacturing industry and improve its performance in the era of digital economy. However, there is little research on the role of the two service strategies in the incentive effect of digital technology integration on enterprise performance. This paper selects 371 high-end equipment manufacturing enterprises in Shanghai and Shenzhen A-shares from 2013 to 2022 as research samples, and explores the mechanism of digital technology integration on the performance of high-end equipment manufacturing enterprises by constructing A model of "digital technology integration - service strategy - enterprise performance". The results show that: (1) Digital technology integration can positively improve the long-term performance of enterprises; (2) Service-oriented strategy plays an intermediary role between digital technology integration and enterprise performance. Digital technology integration can improve short-term performance of enterprises through front-office service-oriented strategy and long-term performance through back-office service-oriented strategy. This paper has enriched the theoretical vision of the incentive effect of existing digital technology on enterprise performance, and provided theoretical support and practical reference for further promoting the integration of digital technology and promoting the high-quality development of high-end equipment manufacturing enterprises.
