To what extent do Chinese construction firms foster linkages with the local economy and support local development outcomes? Despite increasing literature on the impact of Chinese infrastructure projects in Africa, relatively less attention has been paid to the specifics of this interaction, particularly concerning the characteristics of Chinese firms and the host country’s environment in which such partnership unfolds. Drawing on official documents, firm-level surveys and semi-structured interviews, this article examines how both private and public Chinese firms influence local development in Ethiopia’s infrastructure sector. The analysis focuses on several key factors shaping this impact, including employment generation, collaboration and subcontracting with domestic firms, technology and skills transfer and the creation of linkages between infrastructure projects and local manufacturing. The findings indicate that in Ethiopia, many Chinese companies are becoming increasingly integrated with the local economy. However, these synergies are neither uniform nor consistent across all firms or sectors. The study concludes that local economic benefits are contingent upon multiple factors, including the specific characteristics of Chinese firms, the strength of local capacity and the effectiveness of policies designed to regulate and promote local development.
