This study examined the development effects, existing challenges, and potential improvement strategies for private undergraduate colleges in Guangdong Province, China, over the past 40 years. Since establishing the first private higher education institution in 1993, the sector has expanded significantly, with private colleges now accounting for a substantial portion of the province's higher education landscape. The analysis highlights the effectiveness of these institutions in aligning with national educational goals and regional economic needs, as well as their contributions to talent cultivation. However, the study also identifies critical issues, including the quality of talent training, internal governance deficiencies, and the need for enhanced faculty development. Furthermore, it emphasizes the importance of strengthening party building and ideological education within these institutions. The paper proposed comprehensive strategies to address these challenges to improve governance structures, optimize educational quality, and foster a high-quality teaching workforce. Ultimately, this research aims to provide insights that can guide the development of private undergraduate colleges in Guangdong Province, ensuring they contribute effectively to the region's economic and social advancement.
