Bibliometric data for analysis

This study adopted a bibliometric approach to examine 93 articles on CFL textbooks published in well-established journals indexed by the China National Knowledge Infrastructure (CNKI) and Web of Science (WoS) since the Belt and Road Initiative. Specifically, it aims to provide a comprehensive overview of this line of inquiry, including its evolution, research hotspots, and emerging trends, to identify underexplored areas and to offer insights that can inform and advance CFL textbook research both in China and beyond.
