2.2 Research variables
Employment competitiveness is an individual's capacity to secure and sustain job opportunities in the labor market, encompassing vocational knowledge, skills, work experience, social connections, career attitudes, and personality traits. Utilizing career anchor theory and self-efficacy theory, this research identifies five key factors influencing college students' employment competitiveness: interdisciplinary learning, career development and planning, career network expansion, self-efficacy, and employment matching.Interprofessional learning enables students to acquire a broad range of knowledge and skills, fostering integrative and innovative capabilities (Plasman et al., 2022; Sio et al., 2022). Career development and planning cultivate effective strategies by evaluating interests, abilities, and career goals (Esther & Bancy, 2021).Career network expansion facilitates career growth by establishing and maintaining professional relationships that provide access to career information, support, and resources (Su et al., 2020). Self-efficacy impacts motivation, persistence, and behavioral performance, serving as a crucial psychological factor in academic and career achievements (Stroumbakis et al., 2021). Employment fit denotes the alignment between an individual's abilities and the demands of a job, with a high level of fit enhancing career satisfaction and performance (Plasman et al., 2022). The description of the measurement items for the above variables is shown in Table 2.

2.3 Research hypothesis
(4) Interprofessional Learning and Self-Efficacy and Employment matching
Existing research points to the fact that interprofessional learning integrates knowledge from different disciplines and enables students to learn in diverse contexts. Nugroho et al. (2023) showed that this type of learning enhances students' confidence and self-efficacy. Interprofessional learning emphasizes solving real-world problems in different disciplinary contexts and enhances students' problem-solving skills. Su (2022) The study found that CDP combined with STEM education significantly enhanced students' professional skills and self-efficacy. Interprofessional learning requires teamwork, where students from different disciplinary backgrounds collaborate with each other. Hiscox et al. (2022) noted that teamwork enhanced students' self-efficacy and received more support and feedback through collaboration. Huang et al. (2024) (2024) found that interprofessional learning helped students clarify their career direction and improve the clarity of their career decision-making, thus enhancing their self-efficacy. Based on this, the following hypotheses were proposed in this study:
H1: Interprofessional learning has a positive and significant effect on self-efficacy.
Interprofessional learning not only expands students' knowledge but also enhances their competitiveness in multiple fields. It has been shown that interprofessional learning significantly improves students' employment matching, i.e., the fit of students' skills and knowledge with industry needs. Selvi et al. (2019) noted that interdisciplinary learning can contribute to students' achievement of the SDGs while significantly improving students' employability and fit. Sihvola (2014) explored the impact of interdisciplinary education on careers, proposing the T-shaped competency model, which is the possession of in-depth knowledge and skills in a particular field (the vertical part of the T), along with a breadth of competencies across disciplines (the horizontal part of the T). Bagares (2024) and Santos and BAE (2022) showed that students with T-shaped competencies have higher competitiveness and job matches in the job market. Based on this, this study proposes the following hypothesis:
H2: Interdisciplinary learning positively and significantly influences employment matching.
(5) Career development and planning with self-efficacy and employment matching
Self-efficacy is a critical psychological factor in career development and decision-making. The study by Hamzah et al. (2021) examined how career decision self-efficacy impacts college students' career adaptability. It found that self-efficacy significantly influences career adaptability through career preparation behaviors. This indicates that career development planning can boost students' career choice and adaptation abilities by enhancing their self-efficacy. Additionally, Lee et al. (2022) discovered that career decision self-efficacy greatly affects career preparation behaviors and plays a crucial role in improving career adaptability. Thus, the following hypotheses are proposed in this research:
H3: Career development and planning have a positive and significant effect on self-efficacy.
Employment matching degree refers to the degree of fit between an individual's skills and knowledge and the needs of the job. It has been shown that systematic career development and planning can significantly improve an individual's employment fit, i.e., by helping individuals find the most suitable jobs through match optimization algorithms, experiential career planning, personality assessment, and fuzzy hierarchical analysis (Kurt &ı Özbakır, 2020; Snyder & Hartwell, 2023). Based on this, the following hypotheses are proposed in this study:
H4: Career development and planning have a positive and significant effect on employment matching.
(6) Career Network Expansion and Self-Efficacy and Employment matching
Career network expansion is the process by which individuals access career information, resources, and opportunities by establishing and maintaining career connections. This process includes not only networking with peers and professionals, but also involves active participation in professional social events, joining professional associations, attending industry conferences, and utilizing social media platforms. Alemdar et al. (2022) study found that broader and higher-quality professional networks increased Noyce teachers' self-efficacy, leading to higher retention rates in high-need schools. Zhou et al. (2023) The study noted that the number of connections in the film and television industry was significantly and positively related to career decision self-efficacy, and the more extensive the professional network, the stronger the individual's career decision self-efficacy was (Loureiro & Lovett, 2023). This suggests that rich professional network resources and support can significantly enhance individuals' self-confidence and competence in career decision-making. Based on the above review, the following hypotheses are proposed in this study:
H5: Professional network expansion positively and significantly influences self-efficacy.
Expanding one's career network not only provides valuable career information but also increases employment opportunities, aiding individuals in finding the most suitable jobs. Studies indicate that expanding occupational networks can significantly enhance individuals' employment matching. Through these networks, individuals gain access to more career information, comprehend industry trends and job requirements, and identify and seize suitable job opportunities, thereby improving employment matching (Serodio et al., 2024; Ustin et al., 2024). Based on this review, the following hypotheses are proposed in this study.
H6: Career network expansion positively and significantly influences employment matching.
(7) Self-efficacy and Employment Competitiveness
Self-efficacy is an individual's belief and confidence in their ability to perform successfully in a specific task or domain. Kang (2023) and Hayati and Idin (2024) showed that participation in extracurricular activities positively influenced college students' employment self-efficacy through the mediating role of information-seeking strategies, where purposeful and exploratory strategies enhanced this relationship, while unstructured search strategies were negatively associated with it. Furthermore. Kanar and Bouckenooghe (2021) and Pukkinen et al. (2023) studies also found that certain extracurricular activities were positively related to college students' self-efficacy, suggesting that this may influence key outcomes such as employability. These studies suggest that frequent participation in extracurricular activities may increase students' self-efficacy, which in turn may enhance their employability (Cai & Yu, 2024). Based on this, the following hypotheses were proposed in this study:
H7: Self-efficacy has a positive and significant effect on the employment competitiveness of university students.
(8) Employment matching and Job Competitiveness.
A high employment match implies a high degree of congruence between an individual's competencies and the job requirements, leading to increased productivity, job satisfaction, and career potential. Pan et al. (2020) found that higher employment fit significantly improves employee productivity and employment accessibility. Individuals can perform tasks more effectively when their skills and knowledge are highly matched to the demands of the job. Similarly. Birchenall (2008) finding suggest that a high employment match not only enhances an individual's job performance, but also promotes employees' performance in innovative tasks and enhances their adaptability and competitiveness. Based on this, the following hypotheses are proposed in this study:
H8: There is a positive and significant effect of employment matching on the job competitiveness of college students.
(9) The mediating role of self-efficacy
The above hypotheses mentioned that "Interdisciplinary learning has a positive and significant effect on self-efficacy", "Career development and planning has a positive and significant effect on self-efficacy", "Career network expansion has a positive and significant effect on self-efficacy" and "Self-efficacy has a positive and significant effect on college students' employment competitiveness". A significant impact on self-efficacy," "career development and planning positively and significantly impact self-efficacy," "career network expansion positively and significantly influences self-efficacy," and "self-efficacy positively and significantly affects the employment competitiveness of college students." Thus, it is posited that interprofessional learning, career development and planning, and career network expansion enhance college students' employment competitiveness through self-efficacy. Based on this, the following hypotheses are proposed:
H9: Interprofessional learning positively and significantly impacts college students' job competitiveness through self-efficacy.
H10: Career development and planning positively and significantly influence the job competitiveness of college students through self-efficacy.
H11: Career network expansion positively and significantly impacts college students' job competitiveness through self-efficacy.
(10) The mediating role of employment matching
The above hypotheses mentioned that "Interdisciplinary study has a positive and significant effect on the degree of employment matching", "Career development and planning has a positive and significant effect on the degree of employment matching", "Expansion of career network has a positive and significant effect on the degree of employment matching" and "The degree of employment matching has a positive and significant effect on the degree of employment competitiveness of college students". A significant impact on employment matching degree," "career development and planning positively and significantly impact employment matching degree," "career network expansion positively and significantly influences employment matching degree," and "employment matching degree positively and significantly affects the employment competitiveness of college students." Thus, it is posited that interprofessional learning, career development and planning, and career network expansion all enhance college students' employment competitiveness through employment matching degree. Based on this, the following hypotheses are proposed:
H12: Interprofessional learning positively and significantly impacts college students' job competitiveness through employment matching.
H13: Career development and planning positively and significantly influence college students' job competitiveness through employment matching.
H14: Career network expansion positively and significantly impacts college students' job competitiveness through employment matching.
