Investigating Structural Relationships between Professional Identity, Learning Engagement, Academic Self-Efficacy, and University Support: Evidence from Tourism Students in China

In order to foster students’ development and enhance the training quality within tourism programs at universities, this study aims to investigate the relationships among tourism students’ professional identity, academic self-efficacy, learning engagement, and university support. Professional identity refers to learners’ recognition and understanding of their study programs and is viewed as a dynamic, progressive process consisting of professional cognition, professional emotion, and professional appraisal. Data were collected from 333 tourism students studying at Chinese universities. They were analyzed through SPSS and SmartPLS. The results revealed that there is no significant correlation between students’ professional cognition and learning engagement. However, students’ professional emotions and professional appraisals positively influence learning engagement. Moreover, all three dimensions of professional identity exhibit positive effects on students’ academic self-efficacy. Additionally, students’ academic self-efficacy demonstrates a positive impact on learning engagement, and university support is associated with increased learning engagement and academic self-efficacy. This study contributes to a comprehensive understanding of the learning experience of tourism students and aims to facilitate the advancement of tourism education through cultivating students’ professional identity towards tourism and developing students’ career commitment in the tourism industry. Theoretical and practical implications are discussed.


Introduction
Higher education represents a pivotal period during which students engage in professional studies and formulate career aspirations.As of 2023, China boasts the world's largest higher education system [1].The gross enrollment rate in higher education stood at 59.6% in 2022, encompassing a substantial 46.55 million students [2].Concurrently, in tandem with China's burgeoning tourism industry, tourism education is experiencing rapid growth.Notably, the number of Chinese universities offering tourism programs ranks among the highest globally [3].Despite the significant demand for professional talents generated by the booming tourism industry [4], this demand has not translated into a robust attraction for students in higher education.Students enrolled in tourism programs exhibit a relatively low professional identity, contributing to a persistently high rate of program changes.Moreover, those who persist in tourism programs grapple with issues such as low learning engagement, a lack of academic self-efficacy, and weakened endogenous learning motivation.
Tourism management, classified as a secondary discipline under business administration, has faced dual constraints of operational systems and insufficient support since its inception in China [5].The escalating competition among various programs within China's higher education landscape has led to a survival crisis for tourism programs.Presently, many Chinese colleges and universities with tourism offerings contend with the suspension Behav.Sci.2024, 14, 26 2 of 17 or reduction of enrollment [6], resulting in an inadequate supply of qualified tourism professionals.This scarcity of skilled individuals, despite the heightened demand within the tourism industry, poses a significant threat to the sustainable development of the sector [7].
Professional identity serves as a pivotal indicator reflecting students' internal psychological state [8].According to Yu et al. [3], professional identity is not only a significant measure of students' individual values but also a crucial indicator of their career development goals.Learning engagement is regarded as an evaluative metric for students' experiential growth and a predictor of higher education quality.While considerable research has been devoted to the learning engagement of university students [9], there is a noticeable dearth of attention given to the engagement levels of students in tourism programs [3].Additionally, academic self-efficacy stands out as the primary determinant shaping individuals' goal-setting and actions in the realm of learning.It not only has the potential to motivate students in their learning activities but also triggers positive behaviors.Despite some studies confirming the influence of professional identity on learning engagement [10][11][12], few have explored the intricate relationships among professional identity, academic self-efficacy, and learning engagement.Moreover, scant research has been conducted to scrutinize the specific dimensions of professional identity, leaving uncharted territory regarding how students' professional identity impacts their academic self-efficacy and learning engagement.
Furthermore, the university environment, deemed significant for students' learning and living experiences, not only reinforces motivation but also exerts an influence on their learning behavior [13].Recognized as a catalyst for enhancing learning commitment [14] and shaping students' mentality and behavior [15], university support remains a central focus in current research, albeit predominantly centered on identifying the aspects in which universities support students [16,17].Consequently, the extent and manner in which university support influences students' academic self-efficacy and learning engagement remain uncertain.Given the multitude of factors influencing students' learning engagement, there is an urgent need to comprehensively explore the synergistic effects of both endogenous and exogenous factors.Thus, to foster students' development and enhance the training quality within tourism programs, this study endeavors to examine the relationships among professional identity, academic self-efficacy, learning engagement, and university support.
To achieve the research aims and objectives, the remaining paper is presented as follows: First, research hypotheses and a theoretical framework are proposed based on the literature review of professional identity, academic self-efficacy, learning engagement, and university support.Second, the methodology is presented.Third, an analysis of the results is presented, followed by discussions and implications.The research limitations and future research directions are also introduced.

Professional Identity
The word "identity" first originated from Freud, and it has developed into a very rich connotation, involving multiple dimensions such as society, politics, self, and others [18].Professional identity is not only a subordinate branch of identity but also a part of social identity and collective identity [19].Most research focuses on the self and the social affirmation gained in the professional field [20].With the gradual clarification of the subject, the concept of professional identity is defined as learners' understanding of their study programs and their positive attitude toward acceptance, thereby achieving a balance between inner and outer reality.This psychological process is often closely related to the changes and development of the programs [21].In some studies, professional identity refers to learners' acceptance and recognition of their programs from the heart and is transformed into external behavioral motivation.It is a process of gradual transfer of emotion, attitude, and even cognition, which is divided into three dimensions: professional cognition, professional emotion, and professional appraisal [3,22].Learning and understanding knowledge are the basis for students to form an identity with their programs [23].Cognition forms external behavior and internal emotion and is reflected in students' professional practice [24].

Self-Efficacy
Academic self-efficacy represents a specialized application of self-efficacy within the realm of pedagogy, with its conceptual origins rooted in Bandura's work.Scholars have arrived at a consensus regarding its definition.Specifically, self-efficacy is construed as individuals' beliefs in their capacity to successfully attain goals and navigate the environmental factors influencing their lives [25].It stands as a pivotal proximal determinant of behavior [25][26][27].Academic self-efficacy, an extension of self-efficacy, constitutes a subjective assessment of one's capabilities, encompassing self-efficacy in learning ability and self-efficacy in learning behavior [28].Numerous studies indicate that individuals possessing high academic self-efficacy tend to invest more considerable effort in completing academic tasks.Conversely, those with low academic self-efficacy tend to shy away from academic challenges perceived as surpassing their capabilities [29,30].According to Bandura's theory of self-efficacy perception, students' prognostications regarding their aptitude for learning activities significantly influence their motivation, behavior, and academic performance [31].Serving as a crucial intermediary in students' conduct [32], academic self-efficacy plays a vital role across all facets of the learning process [33].
Professional identity and academic self-efficacy serve as indicators reflecting students' cognitive and emotional orientations toward their programs.Tushnova et al. [34] discovered variations in students' professional identity and academic self-efficacy levels across different study stages.Existing research consistently reveals a direct and significant impact of professional identity on academic self-efficacy, establishing a positive correlation between the two [35].Chen et al. [8] posit that heightened professional identity corresponds to increased academic efficacy.Strengthened professional identity fosters an inclination among students to showcase their professional worth, leading to positive evaluations and, consequently, an augmentation of academic self-efficacy [12].In a study by Zhou [36], the mediating role of academic self-efficacy between professional identity and learning engagement among nursing students was investigated, affirming the positive influence of professional identity on academic self-efficacy.This perspective has found support among students enrolled in special education programs as well.Building upon the three dimensions of professional identity, this research posits the following hypotheses: Hypothesis H1a.Professional cognition positively influences academic self-efficacy.Hypothesis H1b.Professional emotion positively influences academic self-efficacy.Hypothesis H1c.Professional appraisal positively influences academic self-efficacy.

Learning Engagement
The term "engagement" initially found application in the service industry [37] before gradually expanding into various domains.When considering students as the focus of research, the concept of learning engagement emerged.Specifically, it denotes the positive and comprehensive mental state of students during the learning process, assessed through the three dimensions of vitality, dedication, and concentration [38].This definition has undergone refinement and evolution in research.According to Kuh et al., learning engagement represents the time, energy, and effort students invest in attaining educational goals, underscoring the significance of learning objectives [39].Connell and Wellborn define learning engagement as the manifestation of intensity and emotional quality in students' initiation and execution of learning activities [40].Subsequently, Fredricks et al. introduced three distinct dimensions of behavior, emotion, and cognition [41].As Internet technology has advanced, an increasing number of studies have focused on evaluating students' psychological and behavioral engagement [42], asserting the pivotal role of psychological engagement alongside behavioral engagement [43].This paper places greater emphasis on students' spiritual learning engagement, accentuating their subjective initiative, with vitality (perseverance in the learning process), dedication (a profound enthusiasm for learning and self-honor), and concentration (focused attention on learning and deriving pleasure from it) as measurement dimensions.
An individual's attitude toward a specific profession is influenced by their cognitive state and psychological processes [44,45].The intensity of identity impacts students' familiarity, affinity, and confidence in the target field [46].According to the Control-Value Theory (CVT), cognition shapes emotional changes [47], and students develop professional cognition through the study of professional theories and related knowledge.Cognition propels emotional changes and establishes emotional connections, thereby influencing learning motivation and autonomy [11].This process aligns with the "cognitive-emotion-behavior" theory, illustrating that cognition shapes emotional changes and, in turn, influences students' learning engagement.Students possessing a high degree of professional identity can effectively sustain elevated levels of learning enthusiasm, thereby maintaining learning engagement [3,48,49].Conversely, a low degree of professional recognition tends to result in a moderate or lower level of college students' learning engagement [50].The research scope extends from students in a specific program to encompass all university students [51,52].The aforementioned studies indicate that the higher students' professional identity, the more positive emotional value they generate, thus enhancing learning engagement, and vice versa.Building upon this, the following hypotheses are proposed: Hypothesis H2a.Professional cognition positively influences learning engagement.Hypothesis H2b.Professional emotion positively influences learning engagement.

Hypothesis H2c. Professional appraisal positively influences learning engagement.
Academic self-efficacy proves to be a more reliable predictor of academic achievement than other cognitive and affective processes [53], exerting a significant influence on learning and behavioral performance [54].According to Bandura's self-efficacy theory, students form anticipated judgments about their abilities in the learning process, consequently influencing their learning engagement [55].Students endowed with high academic self-efficacy exhibit increased confidence in task completion, leading to more active participation and, thereby, enhancing learning engagement [56][57][58].Learning engagement primarily manifests as an external behavioral display, while academic self-efficacy manifests as an internal sense of accomplishment [59].Academic self-efficacy stands as the core driving force behind students' development [60], positively promoting their learning engagement [61].Lin [62] demonstrated the predictive power of multifaceted self-efficacy on various aspects of learning engagement.In e-learning, academic self-efficacy directly and indirectly influences learning engagement [63].Students with high self-efficacy possess a relatively accurate judgment of their ability to complete learning tasks, thereby determining the level of commitment they should dedicate to task completion.Positive emotional motivation propels students to achieve higher levels of learning engagement, resulting in favorable learning outcomes.Consequently, the following hypothesis is proposed: Hypothesis H3.Academic self-efficacy positively influences learning engagement.

University Support
The university environment is crucial for students' academic and social-emotional development [13], playing a vital role in their adaptation [64].University support encompasses learning assistance, social support, academic resources, and fundamental facilities provided by colleges and universities to meet the comprehensive development needs of students, contributing to the realization of university development goals [65].For instance, Azila-Gbettor examined the relationship between university support and students' psychological, academic, and social adjustment during the COVID-19 period [15].University support constitutes a significant component of social support available to students [66], playing a pivotal role in their overall development.Day asserted that university support can mitigate prejudice-based bullying [16], and Guo investigated its impact on reducing depression among bullied students in the Chinese context [17].The aforementioned research delved into the influence of university support on students' depression [67].Simultaneously, students' perceived university support is linked to heightened learning motivation, lower attrition rates, and a sense of belonging to the university, resulting in lower levels of depressive symptoms [68,69] and fostering a qualitative improvement in the learning experience [70].Hence, it is imperative to acknowledge the profound impact of university support on students' learning outcomes.
University support significantly influences students' academic self-efficacy.Learning within an uncertain environment may diminish academic self-efficacy [71], and a high level of university support has been shown to enhance students' academic self-efficacy [72].Notably, there exists a positive correlation between student negotiation and self-efficacy [73].Peer support indirectly impacts the depth of online learning, with its effects mediated by emotion and self-efficacy [74].Positive relationships with both teachers and classmates play a crucial role in alleviating students' negative emotions, reducing adverse physical and mental pressures, and consequently fostering higher academic self-efficacy [75].Supported by teachers and peers, students endeavor to bridge the gap between reality and learning goals [76], forming a correct judgment of their own abilities and, in turn, elevating their academic self-efficacy [77].Thus, this study proposes the following hypothesis: Hypothesis H4.University support positively influences academic self-efficacy.
Social background plays a pivotal role in personal growth and development.When the social background can support the satisfaction of individual needs, individuals are more likely to invest time and energy in achieving goals [78], leading to higher engagement in learning [79].Conversely, the opposite of higher learning engagement is learning burnout.Current research has demonstrated that in the absence of university support and interaction, students are more likely to experience burnout in professional learning activities [80].Administrative support from colleges and universities can effectively alleviate students' learning burnout [81].Factors such as the university's learning atmosphere, scale, and sense of belonging impact students' learning engagement [82,83].Support from teachers and peers in the university environment is also crucial for students [13,41].Teacher support can effectively promote students' emotional and cognitive engagement [84].When students feel supported by teachers, they experience stronger satisfaction and higher learning interest, leading to increased learning engagement.Peer support exhibits a strong correlation with students' learning engagement [85].When students enter a peer group with a higher level of engagement, their own engagement level significantly improves [86].The mutual pressure among peers motivates students to engage more deeply in learning to integrate with their peers.Therefore, university support has a significant correlation with students' learning engagement.Consequently, the hypothesis is proposed: Hypothesis H5.University support positively influences learning engagement.

Survey Instrument
Based on the literature review, a questionnaire was developed to measure prof sional identity, self-efficacy, learning engagement, and perceived university support.T questionnaire consists of five parts: (1) professional identity, (2) academic self-efficacy, learning engagement, (4) university support, and (5) socio-demographic information.particular, professional identity was measured using a scale adapted from previous wo [3,87].It includes three subscales: cognition, emotion, and appraisal.Self-efficacy was sessed with ten items adapted from the validated Chinese version of the General Se Efficacy Scale developed by Schwarzer et al. [88].Learning engagement was assessed u ing the Utrecht Work Engagement Scale (UWES) [89].It contains three subscales (i vigor, dedication, and absorption), and each subscale is evaluated with 3 items.For an ysis, 9 items from the three subscales were treated as a single predictor of learning e gagement following previous work's recommendation [37,90].The UWES-S scale was a proved with high reliability and validity in previous studies for Chinese students [3,9 The measurement of university support was modified from the scale developed by Sae et al. [91], which contains 13 items.The specific measurement items were shown in A pendix A. All the above measurement items were scored on a 5-point Likert scale from (strongly disagree) to 5 (strongly agree).

Data Collection
The sample for this study was tourism management students currently enrolled in 4-year bachelorʹs degree program in China.A snowball sampling method was utilized this study.The research team first approached tourism students from a large public u versity in Jiangsu Province, China.These tourism students were then asked to assist recruiting respondents and were encouraged to share the online survey link with touris students studying at other universities in China.According to Oh and Pyo [92], the sno ball sampling method is useful in increasing generalizability by sampling participan across diverse backgrounds.The data collection took approximately three months to co plete, from March to May 2023.A total of 333 valid questionnaires were obtained and us for data analysis after the screening.

Data Analysis
SPSS 23.0 and SmartPLS 4.0 were employed in this study to analyze the data.Specifically, SPSS 23.0 was first adopted to analyze the demographic profiles of respondents as well as to examine the quality of the data.According to Gotz et al. [93], PLS-SEM is a well-established technique effective for both predictive applications and theory building.Therefore, after the assessment of missing data, outliers, and normality through SPSS 23.0, SmartPLS 4.0 was used to evaluate the reliability and validity of measurement and structural models and to assess the hypothesized relationships among the constructs.

Profile of Respondents
The descriptive analysis showed that among the 333 respondents in this study, 75.80% were females and 24.20% were males.This finding is in line with previous studies indicating there were more female students than male students enrolled in the tourism program in China [3,94].As for the grade distribution, freshman and sophomore respondents accounted for 21.10% and 30.00%, respectively, and junior and senior respondents accounted for 26.70% and 22.20%, respectively.

Common Method Bias
In order to confirm common method variance is not a concern in the current study, a post hoc Harman's single-factor analysis was adopted following Podsakoff et al.'s [95] recommendation.Specifically, the analysis was conducted to check that the amount of variance in observed variables was not explained by one single factor.The results showed the variance accounted for 35.23%, below the suggested threshold of 40.00%.Therefore, common method bias is not a concern in this study.

Assessment of Measurement Model
To evaluate the reliability and validity of the constructs adopted in this study, internal consistency reliability, indicator reliability, convergent validity, and discriminant validity were assessed.Specifically, in terms of measurement model reliability, Cronbach's alpha (α), factor loading, and composite reliability (CR) were assessed.According to Table 1, the Cronbach's alpha values of constructs ranged from 0.900 to 0.962, and the composite reliability values ranged from 0.902 to 0.962, both exceeding the thresholds of 0.700.In addition, all factor loadings are above the minimum level of 0.700.Thus, the data showed satisfactory internal consistency reliability and indicator reliability.As for the model validity, the value of the average variance extracted (AVE) of all constructs is above 0.50, suggesting satisfactory convergent validity (Table 1).Moreover, the square root of the AVE values exceeded the correlation between variables, confirming the discriminant validity of the model (as shown in Table 2).Therefore, the measurement model proved to have sufficient reliability and validity.

Assessment of the Structural Model
First, it is significant to confirm there are no collinearity issues between the constructs.The variance inflation factor (VIF) values for each construct are less than the threshold of 5, indicating that multicollinearity is not a concern in the structural model.Second, the coefficient of determination (R 2 value) and Stone-Geisser's Q 2 value were calculated to evaluate the predictive validity and relevance of the structural model.According to Table 3, with R 2 values of the constructs all above the suggested threshold of 0.10 [96] and Q 2 values of the constructs higher than the threshold of 0.00 [97], the structural model was perceived to have sufficient predictive validity and relevance.Third, the estimated path coefficients and t-statistics of the hypotheses were examined using a bootstrapping approach.Table 4 presents the results of the hypothesized model relationships.Specifically, Hypotheses 1a, 1b, and 1c predicted the positive influences of students' professional cognition, professional emotion, and professional behavior on learning engagement.The results revealed that Hypothesis 1a was accepted at β = 0.200, p < 0.01, Hypothesis 1b was accepted at β = 0.209, p < 0.01, and Hypothesis 1c was accepted at β = 0.211, p < 0.01.The relationship between students' professional cognition and learning engagement was found to be not significant (β = 0.004, p > 0.05), rejecting Hypothesis 2a.However, students' professional emotion and professional appraisal were confirmed to have positive impacts on learning engagement, supporting Hypothesis 2b at β = 0.198, p < 0.01, and Hypothesis 2c at β = 0.249, p < 0.01, respectively.Next, students' academic self-efficacy was confirmed to be positively related to learning engagement (β = 0.310, p < 0.01), supporting Hypothesis 3. Hypothesis 4 and Hypothesis 5 assumed the positive influences of students' perceived university support on their academic self-efficacy and learning engagement, respectively.The results showed that the direct impacts of university support on self-efficacy (β = 0.322, p < 0.01) and learning engagement (β = 0.209, p < 0.01) were significantly positive.Therefore, Hypothesis 4 and 5 were accepted.Figure 2

Indirect and Mediating Effects
In addition to the examination of the direct relationships among varia effects were also tested.In particular, multiple mediation analyses were con amine the role of academic self-efficacy in mediating the influence of profess and university support on learning engagement.To test the mediating effec self-efficacy, the bootstrapping procedure with 5000 samples was employed

Indirect and Mediating Effects
In addition to the examination of the direct relationships among variables, indirect effects were also tested.In particular, multiple mediation analyses were conducted to examine the role of academic self-efficacy in mediating the influence of professional identity and university support on learning engagement.To test the mediating effect of academic self-efficacy, the bootstrapping procedure with 5000 samples was employed.Table 4 presents the results of indirect and mediating effects.
According to Table 5, results showed that professional cognition and professional emotion significantly and indirectly influence learning engagement (β = 0.058, p < 0.01; β = 0.079, p < 0.05) through academic self-efficacy, supporting the significant mediating role of academic self-efficacy.In particular, according to Hair [98], the variance accounted for (VAF) value between 20% and 80% indicates partial mediation, and over 80% indicates full mediation.Therefore, as shown in Table 5, academic self-efficacy plays a full mediating role between professional cognition and learning engagement, as well as a partial mediating role between professional emotion and learning engagement.However, the indirect effect of professional appraisal no learning engagement through academic self-efficacy was not significant (β = 0.054, p > 0.05).This finding suggested that academic self-efficacy was not a significant mediator between professional appraisal and learning engagement.Lastly, the results verified a significant partial mediating role of academic self-efficacy between university support and learning engagement (β = 0.096, p < 0.01).

Discussion and Conclusions
This study aims to investigate the relationships among tourism students' professional identity, academic self-efficacy, learning engagement, and university support.The following conclusions are drawn: (1) The relationship between students' professional cognition and learning engagement was not significant, while students' professional emotion and professional appraisal positively influenced learning engagement.(2) All three dimensions of professional identity positively influenced students' academic self-efficacy.(3) Students' academic self-efficacy had a positive effect on learning engagement, and students' perceived university support positively influenced both learning engagement and academic selfefficacy.The present findings have both theoretical and practical implications, which are listed below.

Theoretical Implications
Firstly, this study enhances the understanding of the relationship between professional identity and learning engagement in tourism students.While numerous studies focus on the connection between specific individual or environmental variables and learning engagement-such as academic self-efficacy; professional identity; and university support-these studies often singularly examine the impact of a solitary variable on students' learning engagement; with scant attention given to tourism students.In particular, Chen et al. [8] believed that professional identity can significantly influence academic selfefficacy, and Lin [62] proved that self-efficacy has a positive impact on learning engagement.Zhang et al. [59] suggested that academic self-efficacy would drive an internal sense of achievement, thus promoting students' learning engagement [61].Professional identity is often positively correlated with learning engagement [3,50].In the study on profes-sional engagement, academic self-efficacy, and learning engagement of nursing students, Zhou [36] verified the positive impact of professional identity on academic self-efficacy and learning engagement and again emphasized the mediating role of academic self-efficacy.In addition, in the study of Turner [77], through the diachronic exploration of teacher support in university support, it was concluded that teacher support can improve students' academic self-efficacy.Jacobs et al.'s study also proves that a high level of college support can positively promote academic self-efficacy [72].University support provides students with the necessary conditions to continue learning and also influences students' learning engagement to a certain extent [79].Recognizing that learning engagement is likely influenced by a blend of personal, professional, and university factors, this study addresses this gap by systematically exploring the interplay among multiple variables for tourism students.Notably, the study validates a theoretical model that investigates the relationships among undergraduate tourism students' professional identity, academic self-efficacy, learning engagement, and university support.
Secondly, this research broadens the scope of inquiries into students' professional identities.Wang [51] et al. explored the relationship between professional identity and the learning engagement of medical students.Chen and Yang [8] explored the relationship between professional identity, learning burnout, and academic self-efficacy for special education students.While existing research on students' professional identity predominantly centers on students in medical and educational programs, little consideration is given to tourism students.DeSimone et al.'s research shows that professional identity can influence students' learning confidence in the field [45], and high professional identity can promote students' learning enthusiasm and thus enhance their learning engagement [3].Undergraduate students in tourism programs exhibit a high rate of program changes, coupled with a notable deficiency in their professional identity.This lack of professional identity detrimentally impacts their learning engagement, potentially diminishing their competitiveness in the talent market and impeding the development of China's tourism industry.By shedding light on the professional identity of tourism students, this study makes valuable contributions toward improving their learning engagement.
Thirdly, this study validates the specific dimensions of professional identity.Building on the work of Yu [3], who identified three dimensions-professional cognition; professional appraisal; and professional emotion-this research further substantiates these dimensions for students in tourism programs.Additionally, by delving into the nuances of these dimensions, the study advances our comprehension of the relationships among professional identity, academic self-efficacy, learning engagement, and perceived university support.

Practical Implications
Firstly, this study's findings yield practical implications for the field of tourism education.Specifically, they offer valuable insights for university administrators seeking to comprehend tourism students' perspectives on their programs, as well as their levels of learning engagement and academic self-efficacy.Notably, students' professional cognition demonstrates no direct correlation with learning engagement, whereas students' professional emotion and professional appraisal exert positive influences on learning engagement.Consequently, universities should not only prioritize the enhancement of students' professional emotion and professional appraisal to elevate their learning engagement but also consider adjustments to the professional curriculum.Implementing targeted measures to foster learning engagement is essential.Concurrently, universities can encourage instructors to reflect on the teaching process and adopt diverse teaching methods to bolster students' enthusiasm and confidence, motivating them to actively engage in their studies.
Secondly, this study's findings contribute to fostering robust interactive relationships between universities and students.Recognizing that universities play a pivotal role in nurturing students' academic prowess and emotional well-being, these aspects are integral to the exploration of students' learning engagement.University support is an important part of the social support available to students [66].Azila-Gbettor has verified that univer-sity support can influence students' psychological state and academic performance during COVID-19 [15].Morley [68] indicated that the greater university support perceived by students, the lower the level of depression and thus the higher the learning engagement.Universities should strive to provide tangible and perceptible support services, thereby fostering students' learning engagement and academic self-efficacy.In reciprocity, students' enhanced learning engagement becomes a catalyst for the ongoing development of the university.
Thirdly, enhancing the learning engagement of tourism students proves beneficial for the growth of the tourism industry.Wu et al. stated that the intervention of students' intrinsic learning motivation can promote students to better improve their learning effectiveness [99] and have higher professional skills.This study examines the multifaceted factors influencing students' learning engagement, contributing to the effective cultivation of high-quality tourism talents.The results show that professional cognition has no significant impact on learning engagement, while professional emotion and professional appraisal have a positive impact on learning engagement.Academic self-efficacy has a positive impact on learning engagement, and university support has a positive impact on learning engagement and academic self-efficacy.Exploring the above factors can effectively improve students' learning effectiveness.In addition, by doing so, it enables a more substantial number of skilled professionals to contribute to and serve the thriving tourism industry.

Limitations and Further Research Suggestions
This study also suffers from some limitations.First, this research focuses on tourism students in China; however, whether the findings apply to students in other programs and other countries remains unexplored.Future research could further test the model across students in different programs and different countries.Second, this study investigated the interrelationships among professional identity, academic self-efficacy, learning engagement, and perceived university support using a quantitative method.The interpretation of the results is somewhat restricted.Future research could utilize a mixture of both quantitative and qualitative research methods to generate more insights into the relationships.Third, given the cross-sectional nature of this study, the analysis of causal relationships in this study also bears limitations.It would be meaningful for future research to conduct a longitudinal study to examine the causal relationships of the research model.
