Introduction
The advent of digital technologies has caused significant disruptions in the business world, impacting industries such as tourism and hospitality.These technologies have fundamentally changed how companies compete and how consumers behave, forcing organizations to adapt through digital transformation.In the digital economy, tourism and hospitality businesses use technology to improve their services and enhance customer experiences.The emergence of digital technologies has played a crucial role in driving change within the tourism and hospitality industry, transforming the way firms operate, the products and services they offer, and the overall business environment [1].The integration of digital technology has improved the attractiveness, effectiveness, accessibility, and sustainability of the tourism and hospitality industry [2].
The tourism and hospitality sectors have been at the forefront of embracing digital innovation, particularly through the implementation of online booking systems for flights and hotels.The integration of information and communication technologies (ICTs) within the industry can be traced back to the 1970s with the introduction of computer reservation systems and later in the 1980s with the development of global distribution systems [3].Today, tourism and hospitality businesses are increasingly utilizing advanced digital technologies to enhance customer engagement, gain insights into customer preferences, and improve operational efficiency.Various cutting-edge technologies, such as artificial intelligence, blockchain, machine learning, the Internet of Things, big data, virtual and augmented reality, smart devices, sensors, robots, drones, beacons, ubiquitous computing, and near-field communications, are driving this transformation within the industry [4].
With the advent of digital technology and its various applications, leadership has evolved to include new characteristics, giving rise to digital leadership as a potent tool for managers to inspire employees toward innovation and excellence [5].The process of digital transformation within an organization goes beyond simply implementing digital technologies.It is intricately tied to the role of leaders who drive the digital strategy and shape the overall direction of the organization [6].In essence, the key to thriving in the digital era lies in embracing a leadership style that fosters adaptation, creativity, and forward-thinking within an organization [7].
Digital leadership capability is crucial for managers to effectively navigate the everchanging business environment, adapt to new challenges, and drive strategic transformations within their organizations [8].Digital leadership entails creating a clear vision for digital processes and implementing it in organizational management.Leaders must be able to leverage digital technology to influence their behavior, as well as that of their team members, to enhance overall organizational performance.This concept encompasses three key components: integrating digital technology into management practices, evolving leadership attitudes and behaviors, and, ultimately, improving organizational effectiveness [7].
Effective digital leaders possess the vision, knowledge, and skills to leverage technology and data to achieve strategic objectives, foster innovation, and enhance organizational performance.They excel at adopting emerging technologies, fostering a digital culture, and aligning digital initiatives with business goals [9,10].Digital leadership also emphasizes agility, adaptability, and continuous learning to stay ahead in a rapidly evolving digital environment.By championing digital initiatives, fostering collaboration, and empowering employees, digital leadership enables organizations to seize opportunities, address challenges, and gain a competitive edge in today's digital-driven business environment [11].
Digital leadership is essential for achieving sustainable competitive advantage as it ensures that organizations are not only responsive to immediate technological changes but also innovating proactively.It plays a crucial role in integrating advanced technologies such as AI, machine learning, and data analytics into business operations.This integration optimizes processes, enhances productivity, and creates unique value propositions that competitors cannot easily replicate [12][13][14].Moreover, digital leadership involves a visionary approach that anticipates future trends and prepares the organization to adapt to emerging technologies, thereby maintaining its market relevance and superiority [15].However, this adoption of technology and digital initiatives can come with its own set of hurdles.This can include issues like employees being hesitant to embrace change, not possessing the required expertise, and struggling with the integration of new software and systems [5].
Digital leadership, marked by the proactive adoption and implementation of advanced digital technologies, is crucial in enhancing an organization's green absorptive capability: the ability to recognize the value of green innovations and apply them effectively.Leaders proficient in digital technologies can drive the integration of sustainable practices by leveraging data analytics, IoT, and AI to monitor and reduce environmental impacts, optimize resource use, and implement sustainable processes [16,17].
By embedding sustainability into the digital transformation agenda, digital leaders enhance their firms' green absorptive capacity, enabling them to stay ahead of regulatory requirements, meet stakeholder expectations for sustainability, and gain a competitive advantage.This strategic alignment supports compliance and efficiency while driving innovation in green technologies and practices, highlighting the symbiotic relationship between digital leadership and green absorptive capability [18].Furthermore, digital lead-ership is crucial in fostering a culture that values and prioritizes sustainability, integrating eco-friendly initiatives into core business strategies [19].
Additionally, green absorptive capability enables organizations to adopt and integrate green innovations, leading to significant competitive advantages [20].Organizations with robust green absorptive capabilities can proactively respond to environmental regulations, staying ahead of competitors and avoiding potential fines or reputational damage [21].
Similarly, eco-innovation allows organizations to effectively meet regulatory compliance and differentiate themselves in competitive markets.By implementing eco-innovations, businesses can reduce costs through improved resource efficiency, such as using less energy or raw materials and minimizing waste, directly enhancing profitability [22,23].Additionally, eco-innovation fosters internal benefits like nurturing a culture of creativity and attracting talent passionate about sustainability, further strengthening the organization.Overall, eco-innovation not only addresses immediate environmental and regulatory challenges but also serves as a cornerstone for sustainable competitive advantage, offering long-term benefits through market differentiation, cost savings, and an enhanced corporate reputation [9].
The literature on leadership and digital transformation is vast, with numerous studies exploring various aspects such as communication [24,25], technology [26], public administration [27], and small-to-medium enterprises [28].While some research has focused on the capabilities required for working with virtual teams, there is still a lack of comprehensive analyses of how digital transformation impacts leadership capabilities overall.There is a growing recognition of the need for a shift in traditional leadership approaches to thrive in the digital age; yet, a cohesive theory linking digital leadership capabilities to sustainable competitive advantage remains elusive, highlighting the importance of further theoretical advancements in this area.
Despite growing recognition of the importance of digital leadership and sustainability, the research on digital leadership in the tourism and hospitality industry is still in its early stages and lacks a comprehensive understanding of its key features and mechanisms [29].The process of digital transformation in the tourism and hospitality industry is fraught with risks and often fails, as highlighted by Kraus et al. [30].Therefore, there is a pressing need for further research to identify the factors that either facilitate or hinder successful digital transformation in businesses operating in this sector [31].This research should encompass businesses of various types and sizes.Despite significant advancements in academia regarding digital transformation in businesses, progress is impeded by ambiguously defined concepts, confusion in terminology, and a lack of a comprehensive theoretical framework [32].
Specifically, there is a lack of thorough explorations and analyses of the existing literature on digital leadership to fully grasp its conceptual meaning, fundamental attributes, and empirical insights to drive sustainable competitive advantage [33].Previous research has often examined digital leadership or eco-innovation in isolation, without considering the interaction between digital capabilities, environmental knowledge absorption, and innovation.Moreover, the specific mechanisms through which green absorptive capability and eco-innovation mediate the relationship between digital leadership and sustainable competitive advantage remain underexplored.This gap underscores the need for a detailed examination of these mediating roles to provide deeper insights into how tourism and hospitality businesses can effectively integrate digital and green strategies.So, this study aims to examine the impact of digital leadership on sustainable competitive advantage, green absorptive capability, and eco-innovation.It also seeks to assess the effects of green absorptive capability and eco-innovation on sustainable competitive advantage and explore their mediating roles in the relationship between digital leadership and sustainable competitive advantage in tourism and hospitality businesses.
By addressing these objectives, this study intends to fill the research gap and provide a comprehensive understanding of how green absorptive capability and eco-innovation mediate the link between digital leadership and sustainable competitive advantage in the tourism and hospitality industry.Delving into these relationships provides valuable opportunities to enrich ongoing academic discussions for three primary reasons.Firstly, in the ever-evolving tourism and hospitality industry, the impact of digital transformation on economic growth and societal progress is significant, as it fosters innovation, job creation, and the enhancement of products and services.Secondly, organizations that possess a profound understanding of leveraging digital transformation and dynamic capabilities to enhance their performance gain a competitive edge, leading to accelerated innovation, agile adaptation to market shifts, and the efficient delivery of value to customers.Lastly, scrutinizing these connections aids organizations in effectively allocating resources, enabling them to prioritize investments in digital transformation initiatives and dynamic capabilities that yield the highest performance impact.

Dynamic Capabilities Theory
Dynamic Capabilities Theory was developed to address the limitations of the resourcebased view in understanding how organizations can continuously adapt and evolve their resources and capabilities in response to rapidly changing market conditions.It serves as both an expansion of the resource-based view and a critique of its static nature when it comes to managing change and innovation [34].Broadly, dynamic capabilities refer to an organization's ability to recognize and capitalize on new opportunities, as well as adapt and protect their knowledge assets, skills, and resources, to maintain a competitive edge over time [35].Microfoundations are seen as the foundational activities that support these capabilities [36].It is emphasized that the performance of individuals, particularly managers, plays a crucial role in the development and execution of dynamic capabilities.The theory of dynamic capabilities focuses on how organizations develop and sustain capabilities that enable them to adapt and respond effectively to evolving environments.These capabilities allow organizations to detect market changes, capitalize on opportunities, and reconfigure their resources and strategies to sustain a competitive advantage [35,37].
The concept of digital transformation brings about a transformative shift in the way businesses operate, driven by the integration of digital technologies and the strategic utilization of essential skills to reshape organizational structures and processes [38,39].This phenomenon of digital transformation is pervasive and inherently uncertain, making it essential to adopt a dynamic capability perspective when studying the role of digital leadership in navigating this evolving landscape.This perspective emphasizes the importance of adaptability and agility in responding to the challenges and opportunities presented by digital transformation [40,41].
Digital leadership exemplifies a dynamic capability as it entails leveraging digital technologies and data-driven strategies to drive innovation and gain a competitive edge.Effective digital leaders must possess the knowledge and skills to adopt emerging technologies, cultivate a digital culture, and align digital initiatives with sustainability objectives [19,42].Green absorptive capability, on the other hand, represents an organization's ability to acquire, assimilate, and apply knowledge related to environmental sustainability.This capability reflects the organization's capacity to understand and respond to environmental trends, regulations, and consumer demands [20,43].By developing green absorptive capability, organizations can seamlessly integrate digital leadership with sustainability practices, utilizing digital technologies to enhance their environment [16,44].Eco-innovation encompasses the creation and adoption of environmentally conscious practices and solutions, showcasing organizations' capacity to adapt and innovate in response to sustainability issues and prospects.By embracing eco-innovation, organizations can harness digital leadership to devise and deploy inventive strategies that tackle environmental issues, set themselves apart in the market, and bolster their sustainable competitive advantage [9,45].

H7. Eco-innovation mediates the link between digital leadership and sustainable competitive advantage.
The hypothesized research framework is presented in Figure 1 below.

Sample and Data Collection Procedures
This research examined middle-level management in Saudi Arabia's five-star hotels and travel agencies.These two sectors were selected due to their significant presence in Saudi Arabia's hospitality and tourism industry, as well as their commonality in catering to international visitors while also focusing on implementing environmentally friendly practices and green initiatives for sustainability.In addition, researchers have long been fascinated by the study of leadership behaviors and their effects on employees' task perfor-mance and organizational success [75].Initially, the focus was solely on leaders and their behaviors, as well as the qualities that make them effective [76].However, as the research progressed, the perspectives of followers were also taken into account to understand how leaders emerge, behave, and influence others.Scholars have identified three main areas in which followers' behavior with their leaders is examined: their personal beliefs, values, and characteristics; their unique job-related experiences; and how they perceive their leaders [77].Hence, middle-level management was chosen as the focal point of this research due to its pivotal role in shaping organizational strategy, fostering innovation in product development, and serving as a conduit for transferring ideas from lower-level employees to top-level executives [78,79].A questionnaire was delivered to businesses after obtaining their verbal permission for its distribution.From 65 travel agencies and 30 five-star hotels, a total of 323 valid surveys were gathered.In total, 37.8% (n = 122) of survey respondents were employed by travel agencies, while 62.2% (n = 201) worked for five-star hotels.

Measures
Digital leadership was assessed using a 7-item scale adapted from Claassen et al. [80], with statements such as "I am involved in decisions that affect my work and my digital work environment" and "My digital literacy is encouraged by my manager".In addition, a 4-item scale taken from Lin and Chen [81] was used to measure green competitive advantage, with statements such as "The firm has a low-cost competitive advantage regarding green management in comparison with major competitors" and "The firm offers better quality green products in comparison with major competitors".Moreover, the green absorptive capability was assessed by a 4-item scale adapted from Özgül and Zehir [82], with statements such as "Our firm can quickly absorb, master, and use green equipment and production processes obtained from outside" and "Our firm is good at acquiring and using external green technology and knowledge".Furthermore, a 7-item scale adapted from Cheng and Shiu [83] and Bocken et al. [84] was used to assess eco-innovation, with statements such as "In the last 2 years, your firm has designed products that reduce the use of materials" and "In the last 2 years, your firm has designed products with components for reuse or recycling.

Data Analysis
This study utilized PLS-SEM, a statistical method for theory validation and extension, for confirmatory and exploratory investigations in hospitality and tourism research [5,[85][86][87].It is best suited for strategic and management studies [88].This study used WarpPLS statistical software 7.0 for data processing and conducted a multi-group analysis to identify significant differences in path coefficients between hotels and travel agencies.
Table 1 shows that the research constructs had composite reliability ratings that exceeded the acceptable threshold (CR > 0.70) and significant item loadings (>0.60, p < 0.05).Convergent validity was confirmed by the AVE values > 0.50 for digital leadership, sustainable competitive advantage, green absorptive capability, and eco-innovation.Since the VIF of each latent variable was ≤3.3, the model was also thought to be free of common method bias.The constructs' discriminant validity was confirmed by calculating the HTMT and confirming that the square root of the AVE for each construct was greater than the offdiagonal correlations (see Tables 2 and 3).

Results of the Multi-Group Analysis (MGA)
Multi-group analysis (MGA) results indicated that the observed differences in path coefficients between hotels and travel agencies were not statistically significant (p > 0.05).In simpler terms, the relationships between variables in the model seemed to be similar for both hotels and travel agencies, see Table 4.

Testing of Hypotheses Results
Figure 2 and Table 5 show that digital leadership (DL) positively affected sustainable competitive advantage (SCA) (β = 0.51, p < 0.01), green absorptive capability (GAC) (β = 0.60, p < 0.01), and eco-innovation (EI) (β = 0.69, p < 0.01).This study indicates that DL increases SCA, GAC, and EI, thereby supporting the hypotheses H1, H2, and H5.In addition, SCA was positively impacted by GAC (β = 0.21, p < 0.01) and EI (β = 0.15, p < 0.01).This study indicates that GAC and EI increase SCA, thereby supporting hypotheses H3 and H6.Additionally, Hayes and Preacher's [90] technique was used to assess the mediation effects of GAC and EI in the DL→SCA relationship.This study found that GAC and EI significantly mediated the DL→SCA relationship, as evidenced by the significant indirect effect and a 95% bootstrapped confidence interval (LL, UL) that did not cross a zero inbetween, supporting H4 and H7, see Table 6.
