Strategic Innovation, Small and Medium Industries, Regional Tourism, Competitiveness, Sustainability, Bibliometric Analysis
Small and Medium Industries (SMIs) are the backbone of the local economy in many regions of Indonesia, significantly contributing to the development of the tourism sector. Strategic innovation in SMI centres is key to increasing regional tourism competitiveness amid increasingly fierce global competition.1,2 Small and Medium Industries (SMIs) serve as the backbone of the local economy across various regions in Indonesia. The existence of SMIs not only contributes to job creation and regional economic strengthening but also serves as a vital pillar in developing an increasingly competitive tourism sector in the era of globalization. In the face of rapidly changing market dynamics and fierce competition, strategic innovation emerged as a key factor that encouraged the increase of regional tourism competitiveness through strengthening SMI centres. As explained by,3 the concept of strategic innovation emphasizes significant changes in products, processes, and business models that must be managed effectively for organizations, including SMIs, to survive and thrive amid external challenges.
Digitalization and technological transformation are the main drivers in the development of SMI innovations, as outlined by4,5 which underscores the need for digital capacity building and cross-sector collaboration to strengthen local economic competitiveness. In the context of tourism5,6 highlighting the role of digital technology in creating smart tourism destinations that improve the tourist experience and the efficiency of destination management. This confirms that strategic innovations that integrate digitalisation and sustainability aspects are very relevant to be developed in SMI centres that support regional tourism.
Comprehensive review by,7 reinforcing the importance of integrating product and process innovation in the tourism sector to support sustainable growth. A collaborative approach to innovation, as put forward by,8 through co-innovation, emphasises that synergy between business actors, the government, and local communities is essential to create shared value and accelerate innovation adoption. National Competitiveness Framework. 9–14 It also provides a strong theoretical foundation in understanding how strategic innovation can create a sustainable competitive advantage for SMIs and regional tourism destinations. In addition, global trends that increasingly prioritize aspects of sustainability and the circular economy, as reviewed by14–16 is an important concern in the development of innovations that are not only oriented to economic growth but also to environmental preservation and social welfare. Social media and digital technology also significantly improve customer engagement and tourist experience, which is a vital aspect in the marketing and development of community-based tourism products and SMIs.17
However, innovation management is not free from challenges, especially in overcoming organisational rigidity that can hinder the adaptation and development of new products.18 Therefore, SMI centres need to adopt adaptive and sustainable innovation strategies to maintain relevance and competitiveness in a dynamic market. Based on the theoretical foundation and previous research findings, this study aims to systematically examine the development of strategic innovation trends in SMI centres that contribute to increasing regional tourism competitiveness in Indonesia. The bibliometric approach was chosen as the. An appropriate method to map the publication patterns, key actors, dominant research themes, and collaborative networks developed over the past two decades. Thus, this study is expected to provide comprehensive insights and strategic recommendations that apply to the development of innovations in the SMI and regional tourism sectors, while answering the needs of digital transformation and sustainability, which are the main demands in the modern era.
Although many studies have addressed innovation and tourism separately, the integration of the two with a systematic approach is still limited. The bibliometric approach offers a quantitative method to map research progress, identify key actors, and uncover collaboration patterns and dominant research themes. Therefore, this study aims to examine the development of strategic innovation trends related to regional tourism competitiveness in SMI centres through a bibliometric analysis of scientific publications over the past two decades. This study is expected to provide comprehensive insights and strategic recommendations for developing innovations in the SMI and tourism sectors. Therefore, based on the above explanation, several research questions were developed to guide this analysis more directly and in-depth, with some questions developed as follows.
The research methodology used in this study is categorised as descriptive. The authors used bibliographic techniques to answer research questions, citing their methodological advantages over conventional qualitative reviews due to their analytical depth and accuracy. This study uses a bibliometric analysis method by collecting data from scientific publications from the Scopus database relevant to strategic innovation, SMIs, and regional tourism during the period 2005-2025, especially for journal articles that have been finalised, in English, open access and hybrid gold. Data is collected using predefined keywords through Boolean logic designed to capture relevant and comprehensive literature. ((“strategic innovation” OR “innovation strategy” OR “strategic innovation”) AND (“small and medium enterprises” OR SMIs OR “small and medium industries” OR “SMI centers”) AND (competitiveness OR “competitive advantage” OR “market competitiveness” OR “competitiveness”) AND (tourism OR tourism OR “regional tourism” OR “local tourism” OR “tourism industry”)). From the results of the data collection, 3,295 article documents were obtained. The document was then filtered back specifically for final journal articles in English, open access, and hybrid gold. As many as 195 documents were found that were ready for further analysis.
The analysis used bibliometric software such as VOSviewer and Bibliometrix to map publication trends, keyword analysis, and collaborative networks between authors, institutions, and countries. This approach allows the identification of research patterns, key actors, and themes that develop quantitatively and visually. The entire process is carried out systematically to ensure the validity and reliability of the data and analysis. Therefore, the power of the research design is further enhanced by incorporating custom-built PRISMA and PICOC frameworks, which contribute to an optimally comprehensive and structured approach (as illustrated in Figure 1).
The data screening process in this study follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses ) framework, which consists of three main stages: Identification, Screening, and Inclusion. In the Identification stage, literature searches were carried out in two leading academic databases, namely Scopus and Web of Science, with a focus on strategic innovation, Small and Medium Industries (SMIs), and regional tourism from 2005 to 2025. The data collected is limited to final journal articles in English and have open access or hybrid gold. This ensures the quality and relevance of the data sources used in the analysis.
Furthermore, at the Screening stage, Boolean logic is used, specifically designed to capture relevant and comprehensive literature. The Boolean logic combines several key terms such as “strategic innovation”, “innovation strategy”, “strategic innovation”, “small and medium enterprises”, “small and medium industries”, “SMI centers”, as well as terms related to competitiveness and tourism such as “competitiveness”, “competitive advantage”, “tourism”, and its variations. From the initial search results, 3,295 article documents were obtained. However, duplicate documents are removed, and filtering is carried out based on inclusion and exclusion criteria.
The inclusion criteria include journal articles that are final, in English, and have open access or hybrid gold status. Meanwhile, the exclusion criteria include incomplete data and articles that do not contain specific predetermined keywords. After this screening process, 1,500 articles from the Scopus database and 1,632 articles from the Web of Science were significantly reduced, leaving articles that meet quality and relevance standards. The last stage is Inclusion, where articles that pass screening and meet all criteria are included in the bibliometric analysis. At this stage, 195 documents articles were found that were within the focus of this study. These articles are the primary databases analysed to identify strategic innovation trends, key actors, dominant themes, and collaboration networks in the context of SMI centres and regional tourism competitiveness. The researcher also uses the PICOC framework as a strategic tool in formulating appropriate and focused research questions, thus allowing for a more in-depth analysis of the problems raised. The PICOC framework, which stands for Population, Intervention, Comparison, Outcome, and Context, serves as a guide to structure research questions by clearly defining the five components. This approach ensures that the questions asked are specific, relevant, and aligned with the study's main objectives.
In Table 1, each element of the PICOC framework is described in detail along with the resulting research questions. This structure not only helps prepare targeted questions but also organises discussions related to the main challenges of the research, so that all important aspects can be thoroughly discussed. By adopting the PICOC framework, researchers can maintain the focus and systematics of the research while increasing clarity and effectiveness in the investigation process. In the data analysis, the advanced VOSviewer software and RStudio Biblioshiny are used, with attention to various units of analysis such as authors, institutions, and countries. The analysis includes co-authorship, co-occurrence, citations, bibliographic grouping, and co-citations, with a complete count method chosen over fractional counting to ensure more comprehensive data coverage.

The network of citations and bibliographic couplings shows the existence of interconnected research clusters, indicating a progressive consolidation of knowledge in strategic innovation in SMIs and tourism. This research's results significantly enrich academic understanding and strategic innovation development practices in Small and Medium Industries (SMI) centres, which drive regional tourism competitiveness. With a comprehensive bibliometric approach, this study successfully maps research trends, key actors, and key themes underlying the development of strategic innovation in the context of regional tourism over the past two decades.
The main contribution of this research lies in identifying the integration of digitalisation and sustainability aspects as the primary driver of strategic innovation that can increase the competitiveness of tourism based on SMI’s centres. These findings confirm that innovation must not only be technical or product-specific but must also include business model transformation, resource management, and cross-sector collaboration that is adaptive to market and environmental dynamics.31–36 Practically, the results of this study provide a strong scientific basis for policymakers, SMIs, and regional tourism stakeholders in formulating and implementing more structured and effective innovation strategies.37–41 The emphasis on multi-stakeholder collaboration and capacity building for digital innovation is a strategic recommendation that can accelerate the adoption of technology and sustainable practices at the local level.29,42–45
In addition, this research opens up space for the development of evidence-based and contextual innovation models, which not only improve the economic performance of SMIs but also strengthen the regional tourism ecosystem as a whole Pérez-Romero et al., 2024).46,30 This implication is significant in facing the challenges of globalisation, changes in tourist behaviour, and environmental and social sustainability demands. Thus, this study not only makes a theoretical contribution in enriching the literature on strategic innovation and tourism, but also provides a real practical impact in increasing the competitiveness and sustainability of regional tourism through strengthening SMI centres.47–51 In the future, the results of this research can serve as a foundation for more in-depth empirical studies and the development of innovation policies that are responsive to local needs and global trends.
The findings of this study affirm the importance of strategic innovations that integrate digitalisation and sustainability as the primary drivers of increasing the competitiveness of tourism based on SMI centres.52–54 The increase in publications and collaborations shows a growing awareness among academics and practitioners of the need for a holistic, innovative approach. However, cross-country and cross-sectoral collaboration must be strengthened to accelerate knowledge transfer and innovation capacity building.55 The practical implications of this research emphasise the need for policies that support the digitalisation of SMIs, continuous innovation training, and the development of an inclusive and adaptive innovation ecosystem. This study also opens up opportunities for further research to explore the empirical implementation of innovation and evaluate its impact on local economic performance and tourism.
The findings of this study expressly affirm that strategic innovations that integrate digitalisation and sustainability aspects are the main drivers in increasing the competitiveness of tourism based on Small and Medium Enterprises (SMIs) centres. This is in line with the current literature that shows that digitalisation not only improves operational efficiency but also expands market access and enriches the personal experience of travellers.6,17 In addition, the integration of sustainability principles in innovation is crucial to ensure that tourism development does not sacrifice natural resources and the social well-being of local communities.7,56,57,22
The increasing number of publications and collaborations across institutions and countries identified in bibliometric analysis reflects the growing awareness among academics and practitioners of the need for a holistic and multidisciplinary innovative approach. Study by24,58–60 emphasizing that collaboration and co-creation between various stakeholders is an important foundation in creating sustainable innovations that are relevant to market needs. However, the results of this study also show that cross-border and cross-sectoral collaboration is still relatively limited, which is an obstacle to accelerating knowledge transfer and innovation capacity building globally.4,5 Therefore, strengthening international and cross-sector collaboration networks is a strategic priority to accelerate the diffusion of innovation and sustainably increase competitiveness. The synergy between strategic innovation and cluster development is a fundamental driver of regional prosperity. As demonstrated by,61 entrepreneurial activities within specific agricultural and industrial sectors significantly contribute to broader economic growth in Indonesia, providing a baseline for how SMI clusters can stimulate local economies. This supports the bibliometric findings that emphasize the long-term impact of SMI development on regional stability.
From a policy perspective, the results of this study emphasise the importance of regulatory support and programs that encourage the digitalisation of SMI centres, including the provision of technology access, human resource training, and incentives for sustainable innovation.3,8,12,62–64 The development of an inclusive and adaptive innovation ecosystem is also critical, where governments, the private sector, academia, and local communities play an active role in creating synergies that support sustainable and competitive innovation.10,11,12,65 In addition, this research opens up opportunities for follow-up studies to explore the empirical implementation of innovation in the field and evaluate its impact on the performance of the local economy and the tourism sector. This kind of empirical research is needed to test the effectiveness of the proposed innovation strategy and to refine the innovation development model that is appropriate to the specific context of the SMI center and regional tourism,21,66–70 these findings strengthen the understanding that strategic innovation that combines digitalization and sustainability is key to accelerating the transformation of SMI centers into the main drivers of regional tourism competitiveness. Multidimensional and collaborative approaches must be continuously developed to ensure innovation generates a competitive advantage and contributes positively to inclusive and sustainable economic development.71 Establishing a recognizable identity is crucial for SMIs operating within tourism centers. In this regard,72 highlight that brand experience and satisfaction are pivotal in building brand loyalty, which is mediated by trust. Integrating these branding elements into SMI strategic innovations can enhance the long-term competitiveness and sustainability of tourism-based clusters.
This research has successfully mapped the evolution of strategic innovation trends within Small and Medium Industry (SMI) centers and their impact on regional tourism competitiveness over the past two decades. Through a systematic bibliometric approach, this study provides comprehensive insights into dominant research themes, influential actors, and evolving collaboration patterns. The findings confirm that digitalization and environmental sustainability are the central pillars of effective innovation strategies in the modern era. To maintain sustainable tourism competitiveness, it is recommended that stakeholders prioritize strengthening cross-sector collaboration and enhancing digital innovation capacity within SMI centers. These strategic steps are essential for bridging the gap between traditional practices and modern technological demands. Finally, further research should focus on empirical studies regarding the practical implementation of these innovations and the quantitative evaluation of their direct impact on the local economy.
The main findings confirm that digitalization and sustainability are the two fundamental pillars driving strategic innovation in SMI centers, while simultaneously strengthening regional tourism competitiveness within an increasingly fierce global context. This demonstrates that innovation transcends mere technological transformation; it represents the integration of sustainability values that foster inclusive and resilient local economic development. Strategically, this study emphasizes the necessity of strengthening multi-stakeholder collaboration—encompassing government, industry, academia, and local communities—alongside enhancing digital innovation capacity within SMI centers. Such measures are crucial to accelerating the adoption of adaptive innovations that remain relevant to evolving market demands and environmental challenges.
In the future, further research is strongly recommended to empirically examine the implementation of these strategic innovations and evaluate their impact directly on local economic growth and the sustainability of the tourism sector. This approach will enrich practical understanding while strengthening the scientific foundation for developing more effective innovation policies and strategies. Thus, this study makes a significant theoretical contribution and offers a practical guide for strengthening SMI centres as a driving force for sustainable and highly competitive regional tourism.
