Competitive strategy has always been the focus of attention of enterprises. This article takes 165 manufacturing firms in Congo as samples and uses the structural equation model to empirically study the impact of competitive strategy on firm innovation performance. The results show that low-cost strategy and differentiation strategy have a significant impact on enterprise innovation performance, R&D innovation plays a partial mediating role in the impact of low-cost strategy and differentiation strategy on innovation performance. The competitive strategy directly affects innovation performance and an indirect effect mediated by R&D innovation. Whether an enterprise implements a differentiation strategy or a low-cost strategy, it promotes the R&D innovation of the enterprise. Implementing the competitive strategy helps increase the R&D innovation, and the R&D innovation is beneficial to the innovation performance of the enterprise.
