1. Introduction
Conventional management approaches focused predominantly on intensifying a firm’s financial performance and maximizing the shareholder value only [
1]. In contrast, today’s businesses deem to follow a sustainable business model that considers a broader view, addressing the interests of all stakeholders, including shareholders, customers, consumers, and communities [
2]. These sustainable practices maximize economic performance and minimize negative externalities while enhancing environmental and social value [
3]. Therefore, businesses are transitioning from traditional and financial operations to more innovative and sustainable activities in response to market volatility, globalization, and regulatory pressures. Corporate social responsibility (CSR) interests policymakers who delineate company activity across several domains, including human rights, environmental concerns, consumer protection, scientific advancement, technology, and employment practices. The global deployment of CSR policies has prompted a significant shift in corporate behavior, leading corporations, either large or small, to operate in a socially responsible manner regarding many issues [
4]. Today’s organizations adapt their operational strategies and develop new competencies to gain a competitive advantage amidst the shifting modern sustainable business approach [
5].
One of the key factors enabling firms to contribute to the modern sustainable business approach is integrating technology into their operations [
6]. By leveraging digital agility, i.e., the ability of business firms to avail emerging digital opportunities in today’s global environment, firms can streamline processes, reduce waste, and enhance efficiency, making sustainability more achievable even with limited resources [
7]. Technology helps manage environmental impacts and supports innovation, enabling businesses to develop eco-friendly products and services that align with global sustainability goals [
8]. However, Industry 4.0 is based on automation and data exchange, whereas Industry 5.0 focuses on human-centric innovation, a collaboration between humans and intelligent systems, and sustainability [
9]. For a firm, this entails adopting cutting-edge technologies like artificial intelligence (AI), the Internet of Things (IoT), and robotics to ensure that those technologies operate harmoniously with sustainable business practices [
10]. Industry 5.0 technologies provide companies with several opportunities to save resource usage, shrink carbon footprints, and develop customized solutions that favor customer satisfaction along with environmental sustainability [
11], which ensures operational efficiency and further builds corporations’ capacity for integrating the Sustainable Development Goals (SDGs) meaningfully into their global sustainability strategies [
12]. The deployment of Industry 5.0 technologies perfectly aligns with the SDGs of the United Nations, including SDG 9 (Industry, Innovation, and Infrastructure), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action). This research analyzes how access to finance facilitates SMEs’ uptake of such technologies, hence promoting sustainable business models that proactively contribute to the SDGs. Policymakers and business executives need to understand this connection to align business strategies with global sustainability agendas.
Nevertheless, digitally agile firms need to mobilize the required resources (i.e., finance) to render a sustainable competitive position for promoting a modern sustainable business model. According to prior studies, the availability of finance was recognized as an important determinant, and its ownership is directly predictive of high performance and facilitates new opportunities [
13]. In this study, our research examines the role of access to finance in small and medium enterprises’ (SMEs’) sustainability in terms of three streams: environmental sustainability, social sustainability, and economic sustainability (Triple Bottom Line), with digital agility as a mediator. In addition, this study also scrutinizes the moderating role of Industry 5.0 in the dynamic relationship between access to finance and digital agility, as well as access to finance and the sustainable performance of SMEs. Digital agility can enhance resource efficiency, fostering innovation and promoting the development of a sustainable business approach [
14], but there is still a research gap on exploring digital agility as a mechanism to bridge access to finance and sustainability performance. In addition, the effect of Industry 5.0 is significant in driving technology adoption in businesses and enhancing sustainable performance [
15]. Thus, there is a research gap from both sides: no study examined the role of digital agility as a mediator between access to finance and the sustainable performance of SMEs. Second, it aims to address the significant gap in the existing literature by using Industry 5.0 as a moderator in the dynamic relationship between access to finance and digital agility, as well as access to finance and the sustainable performance of these SMEs.
This study has several important contributions. Theoretically, it adds to the existing literature on technology adoption and sustainability by investigating how digital agility, Industry 5.0, and access to finance shape sustainability performance in the under-researched context of Hungarian SMEs. Through the integration of the Resource-Based View (RBV) and the Triple Bottom Line approach, this study provides new insights into the determinants of sustainable and digital practices of SMEs. Empirically, this research uses data from 383 SMEs in Hungary and applies state-of-the-art statistical methods—i.e., Partial least squares (PLS-SEM)—to specify access to finance and sustainability as first- and second-order constructs. This enables the research to move beyond traditional regression methods, extracting more sophisticated insights into relationships among important variables. Methodologically, this study contributes something new by combining Structural Equation Modeling (SEM) and Machine Learning (ML) techniques to estimate causal and predictive outcomes. The integration offers a robust framework for future researchers in similar contexts. The findings highlight the importance of investment in enabling SMEs to undertake digital and sustainable projects. This study suggests that managers, policymakers, and stakeholders should invest in and promote digital prospects since these are critical in establishing sustainable business models among SMEs.
The rest of this study is organized as follows:

Section 6 concludes this paper by providing a summary of the main findings, indicating limitations, and outlining research agendas.
4. Results and Findings
We applied SmartPLS 4.0, the advanced tool used in analyzing structural models with high complexities, including second-order constructs, mediations, and moderations. Initially, we assessed screening tests in SPSS beforehand and obtained skewness and kurtosis within acceptable ranges, with values of ±2 (
Table 2) [
50]. In addition, multicollinearity was ruled out because the variance inflation factors were below the threshold of 5, as documented by the study of [
51]. For deeper structural model testing, we applied nonparametric bootstrapping with 5000 replications and the mean replacement of missing values. The hierarchical component model (HCM), explored by PLS-SEM, encompassed second-order structures [
52]. An extended repeated indicator approach was adopted to examine two- and three-dimensional relationships. The exogenous variable of access to finance was segregated into domestic and international finance, with a strong R-squared value of 86.4% and 80.5%, respectively. The endogenous variable, the TBL, was formed from the dimensions of economic sustainability, which accounted for 72.6%; environmental sustainability, 80.3%; and social sustainability, 70.1%. Second-order dimensions of these constructs were examined, revealing significant path correlations. Access to finance and its sub-dimensions were highly correlated: domestic finance stood at 0.929 and international finance at 0.897. The TBL and its dimensions were also highly associated: economic at 0.852, environmental at 0.896, and social at 0.837 (
Figure 2).
4.1. Common Method Bias (CMB)
CMB arises when data are gathered from a single source, utilizing the same respondent simultaneously, which can significantly distort statistical outcomes [
53]. This research used Harman’s one-factor test in SPSS to evaluate the issue, utilizing principal component analysis as the extraction method. The findings revealed seven components with eigenvalues over 1, of which the first factor accounted for just 31.93% of the variance. Consequently, our investigation verified the lack of CMB by determining that the variance of the first component is less than 50%.
4.2. Measurement Model (First Order)
To validate the measurement model, we assessed convergent validity and discriminant validity of our research instrument. Convergent validity assesses the extent to which two theoretically related variables are associated [
54]. Composite reliability (CR), Cronbach’s alpha (CA), factor loadings (FLs) and average variance extracted (AVE) validated the convergent validity, as seen in
Table 2 and
Figure 3. The values indicated that the reliability and validity are firmly established according to the criteria. We assessed the convergent validity of the model using its CR and CA (CR and CA > 0.70) and FL and AVE (AVE and FL > 0.50) [
55,
56]. In Smart PLS, the CA value is a satisfactory measure of reliability, although the CR value is more advantageous. In SEM-PLS, it is permissible for the CR and AVE to surpass 70 percent and 50 percent, respectively [
55].
Discriminant validity refers to differentiating one variable from others [
54]. Henseler et al. [
57] state that the HTMT value must range from 0 to 1. The HTMT value is presented in
Table 3, indicating that all values conform to the specified requirements. This signifies that the model is reliable, and discriminant validity has been acknowledged.
4.3. Measurement Model (2nd Order)
Access to finance and the TBL were higher-order constructs in this study based on two lower-order constructs of domestic finance and international finance and three lower-order constructs of economic sustainability, environmental sustainability, and social sustainability, respectively. In order to establish higher-order construct (HOC) validity, by outer weights, outer loading and VIF values were verified. The outer weights were found significant [
58]. Outer loadings were greater than 0.50 [
52]. Finally, VIF values were found lower than 5. Since, all criterion are met, the HOC validity was established (
Table 4 and
Figure 4).
4.4. Structural Model
The study hypotheses were tested by employing the “bias-corrected and accelerated” bootstrap method using 5000 sub-samples. The findings highlighted that access to finance (β = 0.243;
p < 0.001) and digital agility (β = 0.668;
p < 0.001) significantly contribute to the TBL. Hence, H1 and H2 are supported. In addition, the results suggest that access to finance (β = 0.503;
p < 0.00) has a statistically substantial effect on the digital agility and indirect (meditating) (β = 0.336;
p < 0.00) statistically significant effects on TBL via digital agility. Thus, H3 and H4 are supported. The moderating effects of Industry 5.0 on the relationship between access to finance and digital agility (β = 0.397;
p < 0.001), as well as access to finance and TBL β = 0.209;
p < 0.001) are statistically significant. So, hypotheses H5a and H5b are accepted. As signaled by the R2 value, the present study accounts for 42.6% of the variance in digital agility and 86.5% in TBL. (See
Table 5).
Figure 5 illustrates the moderating role of Industry 5.0 in the relationship between access to finance and the TBL. As shown, when the incorporation of Industry 5.0 is low (see the red line), firms exhibit a low level of engagement with the TBL, even when they have access to finance. However, as Industry 5.0 incorporation increases (see the green line), firms become more engaged in TBL when they have access to finance.
Figure 6 demonstrates the moderating role of Industry 5.0 in the relationship between access to finance and digital agility. The figure indicates that firms are more likely to be digitally agile when they have access to finance and when the incorporation of Industry 5.0 is at its peak. This highlights that Industry 5.0 significantly enhances digital agility in firms having enough finance.
4.5. Machine Learning Analysis
Despite the advantages of PLS-SEM, its limitations, like the non-linear relationships not being detected and low prediction power, caused the stepwise addition of the Extreme Gradient Boosting (XGBoost version 3.0.0) model as a complementary model with the PLS-SEM. PLS-SEM provides a solid method for proposing and providing evidence for complex causal relations between variables and testing theoretical models [
58,
59]. However, it operates on a fairly limited, predefined basis of relationships and assumes linear relationships among the constructs. XGBoost, on the other hand, achieves higher prediction accuracy and greater robustness by leveraging its ability to model non-linear relationships and interactions among variables and robustness [
60]. The XGBoost analysis was conducted using the Python software version 3.13.2. For the first method, latent variable scores from the PLS-SEM analysis were exported and served as the XGBoost input features. To improve the model performance, the hyper-parameters of the XGBoost algorithm, called the best one via grid search, and cross-validation methods were tuned. Data were split into training and testing sets, with 70% of data as training data and the remaining (30%) for testing data, i.e., predictive accuracy and generalizability of the model.
Table 6 lists XGBoost results.
Difference in PLS-SEM and ML Results
In
Figure 7, the SHAP plot shows that Industry 5.0 performs the most significant influence on TBL outcomes, with a clear positive relationship when its values are high. Digital agility shows the second most important contributor of the TBL followed by access to finance. The results of PLS-SEM achieved for this study indicate that digital agility is a powerful determinant of TBL outcomes, followed by Industry 5.0 and access to finance.
4.6. Robustness
Hayes’ Process Macro in SPSS was utilized to test the mediation and moderation effects in the model and confirm the finding’s robustness (
Table 7). This approach added statistical rigor by validating the strength and significance of hypothesized relationships through multiple pathways. The consistent findings strengthen the reliability and generalizability of this study’s conclusions.
4.7. Discussion
The growing focus on sustainable development has spurred many organizations to explore novel strategies for balancing economic, ecological, and societal goals. In the current climate, this study brings together the RBV with the TBL framework to investigate the function of access to financing in fostering organizational sustainability.
The result confirms that domestic and international access to finance considerably impacts TBL outcomes. These findings are consistent with previous research indicating that financial resources are key in enabling sustainability through investment in sophisticated technology, cleaner production, and socially responsible practices [
16]. Local finance helps companies tackle localized issues and develop context-relevant sustainability-building initiatives. Understanding local insights allows firms to customize their strategy to harmonize with local environmental regulations and societal norms. On the other hand, international finance offers access to larger pools, international standards of best practices, and advanced sustainability technologies that allow the firm to benchmark itself against global companies and credible businesses and adopt global innovations. The positive association of digital agility and TBL outcomes reaffirms the critical importance of technological capabilities in the sustainability journey. These results align with previous studies suggesting that technology adoption matters greatly for sustainability [
61]. Thus, digitally agile firms can optimize resource allocation so that all three dimensions of the TBL framework are adequately addressed. The relevance of this finding extends the RBV by illustrating the role of technology as a salient resource for gaining competitive and sustainable advantages [
62].
This study’s findings support a positive association between financial access and digital agility, implying that access to finance helps firms adopt and scale advanced digital technologies. This is consistent with RBV’s proposition and prior study’s findings that financial capital is a building block resource that supports developing and using resource-derived capabilities, such as digital agility [
16]. The findings support the mediating effect of digital agility between access to finance and TBL performance. This implies that digital agility provides a vehicle for institutionalizing financing to achieve sustainability. Companies that can finance to improve their digital capabilities are improving all three dimensions of the Triple Bottom Line, which are economic, environmental, and social sustainability. The findings reveal that Industry 5.0 is a significant moderator between access to finances, the TBL outcomes, and digital agility. Industry 5.0, characterized by its focus on human-centric and sustainable technologies, enhances companies’ capacity to deploy financial resources effectively to reach sustainability objectives. Additionally, it amplifies the influence of financial resources on digital agility, allowing firms to be more embedded and innovative in sustainability.
5. Implications of This Study
5.1. Implications to the Literature
This study makes a number of significant theoretical contributions to strategic management, sustainability, and SME development in emerging economies.
First, it enriches the Resource-Based View (RBV) by conceptualizing access to foreign and domestic finance as a value-creating strategic resource. Then, it proceeds further to identify digital agility as the most important dynamic capability to construct a bridge from financial access towards sustainable performance outcomes. This joined-up approach enriches our understanding of how concrete (financial) and abstract (digital competencies) resources mutually interact to deliver a competitive advantage in resource-constrained environments, like the case of Hungary.
Second, this study enriches the Triple Bottom Line (TBL) framework by placing Industry 5.0 and digital agility as complementary drivers of economic, environmental, and social sustainability. By modeling sustainability as a second-order construct, this study addresses the fragmented nature of earlier research and offers a more holistic, multi-dimensional understanding of sustainable performance.
Third, the proposition of Industry 5.0 as a moderator offers a new theoretical contribution to the understanding of the impact of human-centric collaborative technologies in driving sustainability outcomes. This contributes to emerging scholarship that seeks to link digital transformation with inclusive, people-centered development and shows how Industry 5.0 technologies serve as catalysts in strengthening the finance–agility–sustainability nexus.
Fourth, this study contributes methodologically by combining Structural Equation Modeling (SEM) with Machine Learning (ML), presenting a hybrid analytical framework that enhances both explanatory power and predictive accuracy. This integrated design is a new opening for the testing of models and verifying theories in scientific studies of SMEs and sustainability.
Fifth, by second-order conceptualizing sustainability performance and access to finance, this study overcomes the limitations of earlier first-order conceptualizations to allow a finer examination of the interconnected dimensions in each construct.
5.2. Implications for Practice
This study also offers several important practical implications for SME managers, policymakers, and support organizations within emerging economies.
First, the study results revealed that access to finance is not just about funding availability but also a catalyst for digital agility building, which in turn renders SMEs economically, environmentally, and socially sustainable. SME managers are meant to obtain access to finance and align it with technology spending that increases agility, innovation, and operational performance.
Second, this research emphasizes that digital agility is both a technical capacity and a strategic driver. Flexible in-house systems should be built by SMEs, and human-focused technologies need to be introduced according to Industry 5.0. Such measures will create increased resilience and competitiveness in evolving markets.
Third, the results call for targeted action from governments, NGOs, and financial institutions. These actors should develop customized financing schemes, capacity-building programs, and digital infrastructure to support SMEs in their digital transformation journey. Financial access must be complemented by training and technical support in order to achieve significant and widespread adoption.
Fourth, policymakers should promote a framework that fosters scaling Industry 5.0 technologies in SMEs—i.e., human–robot collaborations, AI-human interaction systems, and inclusive designs. This will contribute to the establishment of sustainable, innovation-driven, and socially inclusive economies.
Finally, the mixed-method approach using SEM and ML demonstrates how data analysis can support strategic decision making for SMEs. Managers, consultants, and policymakers can adopt the hybrid model for measuring intervention effectiveness, forecasting sustainability performance, and implementing evidence-based adjustments to strategy and policy.
6. Conclusions and Limitations
Financial capital has traditionally been seen as the key to business operation and sustainability. More recent research identifies the growing evidence of digital competencies having an even more central role. While this is a trend, the interplay between financial access and digital responsiveness remains poorly understood, particularly among SMEs that are challenged by balancing financial access, digitalization, and sustainability. This study addresses this gap by emphasizing that access to finance alone is insufficient—SMEs must also be digitally agile to effectively utilize resources for sustainability.
Using data from 383 manufacturing SME managers in Hungary, this study employs SEM and Machine Learning to analyze the relationships between access to finance, digital agility, and sustainability (TBL). Results confirm that access to finance enhances the TBL widely and enhances digital agility. Digital agility is the mediator between financial access and the TBL, and, hence, SMEs must invest in digital capabilities in addition to financing. Industry 5.0 is also the moderator between digital agility, financial access, and TBL. The PLS-SEM model explains 86.5% variance in TBL, and XGBoost indicates that digital agility is the strongest predictor followed by Industry 5.0 and financial access. These results emphasize the need for combining classical statistical analysis with Machine Learning to have improved financial and technological intelligence. Policymakers ought to enhance access to finance but encourage embracing Industry 5.0. The present research is a road map that SMEs and policymakers can use for building sustainability via digital transformation, providing theoretical contributions and practical implications for long-run business resilience in a more digitized world.
There are few limitations to this study. First, it focuses on SMEs in Hungary, so the findings may have limited external generalizability. Despite providing important implications in an emerging market setting, results from Hungary’s unique economic, cultural, and regulated environment may not accurately reflect the context of other regions or advanced economies towards SMEs. Second, this research examines access to finance as a second-order construct (domestic and international), and its relationship with digital agility and TBLs is analyzed. Nevertheless, the model failed to include other potentially influential factors, such as managerial competencies, market competition, or organizational culture—which may limit a holistic understanding of the determinants of sustainable performance. Third, although this study uses SEM and a Machine Learning approach for the analysis, using cross-sectional data prevents us from establishing temporal causality. Longitudinal design could provide an insightful understanding of the relationship between access to finance and digital agility on long-term sustainability performance.
