4.1. Measurement Model
The Partial Least Squares Structural Equation Model (PLS-SEM) was used in this study instead of the Covariance-Based Structural Equation Model (CB-SEM), mainly for the following reasons. Firstly, this study aims to predict and explain how the resource integration ability of cross-border mobile talent drives cross-border EdTech entrepreneurship, which requires exploratory analysis rather than strict theoretical verification. PLS-SEM performs better in predictive-oriented research. Secondly, the research model includes the second-order formability concept (RIC), and PLS-SEM more clearly and accurately processes formability measurement models.

According to the existing PLS-SEM evaluation criteria, we tested the reflective measurement model, judged the measurement reliability and validity of latent variables, and focused on the analysis of indicator reliability, internal consistency reliability, aggregation validity, and discrimination validity [
34]. All latent variables were set as reflective and were measured with a multi-item Likert scale adapted from the mature scale. Among them, the human capital measurement was adapted from the analytical framework of Unger et al. (2011) [
19], social capital was measured from the dimensions of social network resources and interpersonal relationships [
22], and resource integration ability (RIC) was measured based on the theoretical logic of resource arrangement [
30]. Cross-border EdTech entrepreneurship (EC) is a key dependent variable that reflects the willingness of globally mobile talent to engage in cross-border EdTech entrepreneurship and reflects sustainable education. The measurement items are “If given the opportunity, I would prefer a role involving cross-border digital education or innovation” and “I intend to take concrete steps towards such initiatives within the next 12 months”.
All questions were scored on a seven-level scale, reflecting the respondents’ recognition of the relevant expressions. To verify the validity of aggregation, we analyzed the mean variance extraction value (AVE) and combination reliability (CR). At the same time, according to the standard of Henseler et al. (2015) [
35], discrimination validity was tested using the heterogeneity–homogeneity ratio (HTMT).
The “globally mobile talent” in this study included non-Chinese nationals who were pursuing a master’s degree or working at universities in China. Therefore, the survey respondents of this study were international students and graduated multinational professionals in China, covering 29 countries in Asia, Africa, and other regions, with a total of 318 respondents. From a nationality composition perspective, the respondents were mainly from countries such as Pakistan (39.0%), Nigeria (11.0%), Kenya (5.7%), and Ethiopia (4.7%), reflecting the geographical diversity of “globally mobile talent”. These interviewees had cross-border learning or working experience and were studying for master’s or doctoral degrees at universities of the Chinese Academy of Sciences and other cooperative institutions. Their professional backgrounds covered natural science, engineering technology, environmental science, geographic information science, biology, and other fields.
Indicator reliability was first examined. All standardized outer loadings exceeded the minimum recommended threshold of 0.70, indicating that each indicator shared sufficient variance with its corresponding construct. More specifically, human capital loadings ranged from 0.86 to 0.89, social capital from 0.84 to 0.91, resource identification and acquisition from 0.80 to 0.89, and resource integration and utilization from 0.82 to 0.90. Entrepreneurial choice exhibited the highest loadings (0.90 and 0.93), indicating exceptional indicator–construct correspondence.
Internal consistency reliability was tested using Cronbach’s alpha and composite reliability (CR). All constructs demonstrated values above the 0.70 criterion, confirming satisfactory internal reliability. Human capital (α = 0.88; CR = 0.92) and social capital (α = 0.90; CR = 0.93) showed particularly strong reliability. Resource identification and acquisition, as well as resource integration and utilization, also exceeded reliability thresholds, indicating that measurement error is not a likely source of bias in the structural model.
The average variance extracted (AVE) was used to assess convergent validity, and the AVE values of all constructs were above the recommended standard of 0.50, indicating that most of the variance in the indicators can be explained by the construct. The AVE values for human capital and social capital were 0.75 and 0.77, respectively, while the AVE value for entrepreneurial choice reached 0.84, which further suggests a relatively strong convergent validity. The results of indicator loadings, reliability, and convergent validity are reported in
Table 1.
Discriminant validity was examined in two ways, namely, the Fornell–Larcker criterion and the heterotrait–monotrait ratio (HTMT).
Table 2 presents the Fornell–Larcker results. The square root of each construct’s AVE (diagonal values) is greater than its correlation coefficients with other constructs. This confirms that each construct is more closely related to its own indicators than to those of other constructs. This finding illustrates that the latent variables exhibit good discriminative power both conceptually and empirically.
The HTMT results shown in
Table 3 further support discriminant validity. All HTMT ratios are below the conservative threshold of 0.85, indicating no severe multicollinearity or construct redundancy, and the distinctiveness of each conceptual domain in the model is clear.
In summary, the systematic evaluation of indicator reliability, internal consistency reliability, convergent validity, and discriminant validity shows that the reflective measurement model demonstrates sound psychometric properties and is suitable for subsequent analysis of the structural model.
Higher-order construct specification (second-order formative RIC)
Resource integration capability (RIC) is the core dynamic ability to identify, acquire, combine, and reconfigure heterogeneous resources in a dynamic environment to create value. Its connotation includes two logically progressive but functionally complementary dimensions: Resource Identification and Acquisition (RIA) and Resource Integration and Utilization (RIU). RIA focuses on the perception and introduction of external resources, addressing the questions of “what is available” and “how to obtain it”. Meanwhile, RIU focuses on the internal reconstruction and value transformation of acquired resources, solving the problems of “how to use them well” and “how to dynamically adapt”. Therefore, as a second-order forming concept, RIC enables cross-border mobile talents to transform knowledge, networks, and technological resources dispersed in different institutional and cultural backgrounds into feasible entrepreneurial actions through the synergistic effect of the two dimensions of RIA and RIU. To reflect the above variables well, in this study, we measured three items for RIA, including “I can identify the key resources needed to move a project forward”, and three items for RIU, including “I can reorganize plans when policies, markets, or technologies change”. Resource integration capability (RIC) was modeled as a formative second-order construct and was assessed with a two-stage approach. The reason why RIC is set as a formative second-order construct is that its two dimensions (RIA and RIU) complement each other functionally, progress logically, and together form the micro foundation of dynamic capabilities. There is no necessary high correlation between RIA and RIU, and an individual may only be skilled in identifying resources or utilizing resources. Therefore, RIC is not a single ability, and only through a formative model can it fully reflect the core connotations of its corresponding dynamic abilities of ‘perception’, ‘grasp’, and ‘reconstruction’. In the first stage, RIA and RIU were estimated as reflective first-order constructs whose latent variable scores became formative indicators in the second stage to build the second-order RIC construct:
In this study, we defined resource integration capability (RIC) as a dynamic capability consisting of two dimensions: resource identification and acquisition (RIA) and resource integration and utilization (RIU). Because these two dimensions theoretically jointly shape different aspects of RIC and there is no necessary high correlation, RIC was set as a formative second-order construct rather than a reflective one. In the specific estimation, a two-stage method was adopted. In the first stage, RIA and RIU were used as first-order reflective constructs to measure the model estimation and obtain their respective latent variable scores. In the second stage, these scores were used as formative indicators to construct a second-order RIC using partial least squares structural equation modeling. As shown in
Table 4, The weights of formative indicators reached a significant level (RIA weight = 0.48, t = 6.82,
p < 0.001; RIU weight = 0.55, t = 8.14,
p < 0.001), and the variance inflation factors (VIFs) were 2.15 and 2.08, respectively, far below the critical value of 5.0, indicating that there is no severe multicollinearity between the two dimensions.
4.6. Multigroup Analysis (MGA)
To identify heterogeneity among respondents and test whether the structural relationships would differ from individual characteristics, multigroup analysis (MGA) was performed using the permutation-based procedure with 5000 permutations. Following the existing PLS-SEM multigroup analysis method, we used the MICOM program to evaluate measurement invariance. The program consists of three progressive steps: (1) configuration invariance, (2) composition invariance, and (3) equality test of mean and variance. Firstly, configuration invariance was established by ensuring that all groups used the same measurement items, data processing methods, and algorithm settings. Secondly, we compared the original composite variable correlation values between groups with the empirical distribution obtained through 5000 permutation samples to test the compositional invariance. The results showed that the original correlation values of all constructs were higher than the critical value of the 5% percentile of the permutation distribution, indicating that the compositional invariance of each construct holds. Thirdly, we evaluated the equality of the mean and variance between groups. The results showed that the confidence intervals of the constructs all contained zero, which is sufficient to support meaningful comparisons of cross-group path coefficients. Therefore, the conditions for conducting reliable multigroup analysis were met, and subsequent subgroup comparisons had sufficient rationality.
We investigated two different groups of participants. The first group compared those who had received entrepreneurial or innovation-related training with those who had not. The second group consisted of those with prior entrepreneurial experience and those without prior venture exposure. The MGA results reveal that human capital has a greater impact on resource integration capability for participants who had received entrepreneurial training. This suggests that systematic training enhances individuals’ abilities to more effectively identify and mobilize resources for cross-border EdTech initiatives. In comparison, social capital has a significantly larger effect on resource integration capability for individuals with prior entrepreneurial experience, demonstrating how previous venture experience improves the ability to form institutional ties, and gain support from their social network.
These differences are summarized in
Table 9, which records subgroup-specific regression coefficients and permutation-based significance values. Notably, the effect of resource integration capability on entrepreneurial choice did not differ significantly across groups, implying that previous entrepreneurial experience does not affect an individual’s likelihood of engaging in business ventures once their resource integration capability has been built.
4.7. Common-Method Bias and Endogeneity Test
Given the self-reported nature of the data, several procedures were employed to reduce the potential influence of common-method bias (CMB). Anonymity and randomization were integrated into the survey design to reduce evaluation apprehension and consistency motifs. Statistically, three independent diagnostic strategies were applied. First, Harman’s single-factor test indicated that no single factor accounted for more than 50 percent of the variance. Second, the measured marker variable technique showed negligible partial correlations between the marker construct and the substantive constructs. Thirdly, research suggested that the VIF values should be less than 5.0 to avoid multicollinearity issues [
36], while in this study, the VIF values for all structures with complete collinearity were below the threshold of 5.0. Together, these results indicate that neither CMB nor pathological collinearity is present in the model.
To further address potential endogeneity—which could arise from reverse causality or omitted variable bias—we employed the Gaussian copula approach and the two-stage residual inclusion (2SRI) model. A key challenge in endogeneity testing is selecting valid instrumental variables (IVs). In the 2SRI model, language proficiency and training participation were used as exogenous instrumental variables. The rationale for these choices is grounded in both theoretical relevance and exclusion restriction logic.
Regarding relevance, language proficiency is a fundamental tool for cross-border communication and knowledge acquisition. Higher proficiency enables individuals to more effectively access, comprehend, and assimilate diverse information and technical resources from global networks, thereby directly enhancing their capacities to integrate those resources. Similarly, participation in entrepreneurship or innovation-related training programs provides individuals with structured frameworks and practical heuristics for opportunity evaluation and resource mobilization, which are core components of RIC. Thus, both variables are theoretically expected to be strong predictors of an individual’s RIC.
Regarding the exclusion restriction, language proficiency and training participation are argued to not directly influence the decision to engage in EdTech entrepreneurship, except through their impact on RIC. While language skills might seem broadly beneficial, in the specific context of cross-border EdTech, their primary function is to enable the complex synthesis of technical, pedagogical, and institutional knowledge from different cultural spheres—a process central to RIC. Once RIC is accounted for, the residual direct effect of language on the choice to start a venture is likely negligible. For training participation, the theoretical argument is more nuanced but equally defensible. Training programs do not typically provide the tangible resources (e.g., seed funding, co-founder teams, specific market contracts) directly required for venture launch. Instead, they equip participants with the cognitive frameworks and skills to better identify, combine, and utilize such resources. Therefore, while training builds RIC, its influence on the ultimate entrepreneurial choice is indirect and fully mediated by this enhanced capability. This logic satisfies the theoretical requirement for exogeneity.
To empirically validate the relevance condition, we examined the first-stage regression results (with RIC as the dependent variable and the instruments, along with all exogenous controls, as independent variables). Both instruments exhibited strong and statistically significant coefficients, and the Sanderson–Windmeijer F-statistic for the excluded instruments was substantially above the conventional threshold of 10, mitigating concerns about weak instruments. In the second stage, the residual inclusion term from the 2SRI model was nonsignificant, and the copula terms in the Gaussian copula approach were also statistically insignificant. These results suggest that endogeneity bias does not pose a significant threat to the consistency of our structural path estimates, thereby reinforcing the reliability of the findings.
The CMB and collinearity results are presented in
Figure 2 to further complement the above diagnostics, illustrating the full collinearity VIF values for all the constructs in the model. All values fall well below the 5.0 threshold [
36], further confirming that neither common-method bias nor multicollinearity is present in the structural model.
4.8. Synthesis of Findings
The findings suggest that resource integration capability plays a key role in enabling the application of human capital and social capital in the entrepreneurial process. Human capital can enable individuals to master professional knowledge, technical ability, and analytical methods and identify digital education market needs more accurately, which provides support for H1. Social capital can help individuals build multiple social networks, connect with various institutional resources, and find partners, information sources, and support systems on a global scale, which provides support for H2. However, the existence of human and social capital alone cannot support complete entrepreneurial behavior, and resource integration capability is the key to transforming these resources into practical EdTech entrepreneurship actions. This ability, embodied in the EdTech field, is the ability of individuals to accurately identify the required resources, obtain resources from multiple scenarios, and reorganize them into feasible educational services.
Resource integration capability shows a significant association with entrepreneurial choice, which provides support for H3, and this conclusion has been verified in different dependent variable codes, estimation methods, and out-of-sample prediction tests. Multigroup analysis also suggested that there are individual differences in the development of resource integration capability: entrepreneurial training was positively associated with resource integration capability, and past entrepreneurial experience can positively empower social capital. This also shows that the effective transformation of resources requires not only having resources but also accumulating experience in resource search, application, and allocation in an uncertain environment, thus clarifying the essential difference between resource ownership and resource mobilization.
From a theoretical value extension perspective, the research also clarifies the core role of resource integration capability in sustainable digital education. Cross-border EdTech entrepreneurship provides educational services digitally without physical mobility, which not only reduces environmental pressure but also serves more users, which provides support for H4. However, digital technology itself does not have natural environmental benefits, and its sustainable value can only be realized when individuals can integrate technical, human capital, and institutional resources into accessible and extensible long-term digital education programs. Globally mobile talent with strong resource integration capability can not only better connect with transnational networks and acquire cutting-edge knowledge, but also actively promote knowledge dissemination and digital inclusion. Its abilities can help create sustainable digital education services and reduce carbon emissions while potentially improving global education accessibility.
These research conclusions can provide a clear direction for policy formulation and system construction. Universities and policy makers should put capacity-building first, rather than simply attracting talent or investing in digital infrastructure. Through structured tutor guidance, platform cooperation opportunities, and experiential entrepreneurship education, individuals can learn to efficiently tap and use resources across scenes, and international talents can turn potential resources into practical and sustainable digital education achievements. Resource integration capability is not only the core element of entrepreneurial behavior but also the key to promoting the sustainable development of education in cross-border digital learning scenarios.
