<p>This study investigates the technological catch-up strategies of three Chinese latecomer firms: BYD, Haier, and Mindray Medical from their beginning to 2024. It aims to examines the skills and competencies needed for technical “catch-up,” and examines how latecomer companies cross the technological gap, identifying important abilities and creating a framework for understanding these dynamics. The study also discovers how innovation methods impact China’s industrial system’s catch-up performance under different scenarios. Longitudinal comparative case studies examined yearly reports, archival data, expert and executive interviews, and social media data. Substantiation was done using thematic analysis and triangulation at each developmental stage (catch-up, transcendence, and frontier), consumer demand, innovation tactics and catch-up performance are examined. Enterprises first built manufacturing capabilities (design, production, certification) before innovating. Innovation tactics varied through opportunity gap (technology, market, institutional) and development stage. Integrating internal and external knowledge resources, using the local market for learning and expansion, and adjusting to client requests were stressed. Government policy, financial backing, and R&amp;D investment also mattered. The study acknowledges limitations such as the relatively small sample size and suggests avenues for future research to address these limitations. The study highlights how client demand, innovation initiatives, and business performance change over development. The findings include creating initial manufacturing capabilities, strategically adjusting innovation methods to shifting opportunity gaps, integrating internal and external knowledge resources, and using the home market to expand internationally. Latecomer enterprises may strategically match their innovation plans with available possibilities to catch up technologically.</p>
