The Impact of Driving Factors on the High-Quality Development of Higher Vocational Colleges from the Perspective of Lifelong Education: The Mediating Role of Teachers’ and Students’ Self-Efficacy

With the continuous advancement of the construction of a national lifelong learning system and the deepening reform of the modern vocational education system, exploring the internal and external driving factors underlying the high-quality development of higher vocational colleges in border regions can effectively address several prominent challenges faced by northern higher vocational institutions, including insufficient connotative development in relation to construction requirements, inadequate motivation for autonomous learning among teachers and students, and difficulties in adapting lifelong education services to the needs of regional industries. Therefore, this research has significant practical implications.Drawing on self-efficacy theory and lifelong education theory, this study clarifies the transmission mechanisms among variables and constructs a theoretical model centered on lifelong education driving factors, teachers’ and students’ self-efficacy, and the high-quality development of higher vocational colleges. The study conducted a survey among 14 public higher vocational colleges in Heilongjiang Province, collecting 628 valid teacher questionnaires and 864 valid student questionnaires. Empirical analysis was conducted using SPSS 26.0 and the PROCESS macro, including reliability and validity tests, correlation analysis, and Bootstrap tests of mediating effects.The empirical results reveal several key findings. First, four driving factors associated with lifelong education—digital learning resource provision, the implementation of industry–education integration, the cultivation of a lifelong learning-oriented campus environment, and modern institutional governance—can all positively promote the high-quality development of higher vocational colleges. Second, these four types of factors significantly enhance the self-efficacy levels of both teachers and students. Finally, teachers’ and students’ self-efficacy plays a mediating role in this process: various lifelong education-related factors not only directly improve the quality of institutional development but also indirectly facilitate the connotative development of colleges by strengthening teachers’ and students’ confidence in learning and career development.Based on the practical context of higher vocational education in Heilongjiang Province, this study enriches the theoretical framework concerning institutional development from the perspective of lifelong education and provides two practical implications for higher vocational colleges in northern border regions. Higher vocational institutions should not only align their educational practices with local industrial characteristics but also focus on stimulating the subjective initiative of teachers and students, thereby establishing a sustainable and stable model of high-quality development.
