Technological innovation has become the core driving force for achieving high-quality economic development and promoting industrial transformation and upgrading in China. CiteSpace was utilized to conduct a knowledge mapping analysis on authoritative journal articles indexed in the China National Knowledge Internet（CNKI） database. The results indicate a significant increase in the number of publications starting from 2006. Highly cited articles focus on areas such as industrial agglomeration and independent innovation, with a noticeable shift in high-frequency keywords. Keyword clustering analysis reveals that research primarily revolves around types and forms of innovation, influencing factors, indicator systems and evaluation, and countermeasures. The timeline of keyword occurrences shows that technological innovation and innovation capability have consistently been hot topics of research. The cooperation among authors and institutions remains largely dispersed. Finally, some suggestions for the future development of the research field are put forward.
