This study examines the influence of China-Africa infrastructure interaction on the performance of listed firms in Africa. The study finds: 1) Chinese FDI and development assistance to Africa increased rapidly from 2003 to 2018, focusing on infrastructure development. 2) Empirical analysis found that China-Africa infrastructure interaction positively affects the market value added of African listed firms. Firms that interacted through directorship or ownership had higher market value added compared to non-interacting firms. 3) Comparisons of performance measures (ROA, labor productivity) between interacting and non-interacting firms found that interacting firms had better performance. 4) The study concludes Chinese investment in Africa infrastructure benefits local firms' performance,
