The Impact of Knowledge Management and Organizational Learning Promotion in Small and Medium Enterprises on the Implementation of Industry 4.0 and Competitiveness

: The transformation and upgrading of small-and medium-sized enterprises (SMEs) need to align with global industrial development trends and can further assist SMEs in sustainable operation. In recent years, major industrial countries, such as Germany, China, and the United States, have promoted policies like Industry 4.0 or advanced manufacturing as part of their national manufacturing transformation strategies. In contrast, how SMEs follow these global industrial development trends and effectively apply new technologies hinges on internal knowledge management and organizational learning. To achieve the benefits of new technology implementation, enterprises must establish an effective knowledge management and organizational learning mechanism and promotion practices. The Taiwanese government has also adopted Industry 4.0 as an essential tool for assisting the transformation and upgrading of SMEs. Therefore, this study surveyed 129 SMEs in the Taiwanese metal industry, using a one-way ANOVA, Pearson correlation analysis, and simple regression analysis to explore the impact of the internal promotion of knowledge management and organizational learning on the introduction of Industry 4.0 and the enhancement in competitiveness. The results of this study indicate that the promotion of knowledge management and organizational learning contributes to the effective adoption of Industry 4.0 and the enhancement in competitiveness, showing significant correlations between these factors. Thus, the findings can serve as a reference for other partner countries.

In today's fiercely competitive market, how small-and medium-sized enterprises (SMEs) can enhance their competitiveness to achieve sustainable development has become a primary task for government units worldwide in promoting industrial transformation and upgrading.Under the trend of global market supply chain reorganization and the development of Industry 4.0, organizational learning capabilities can significantly enhance the impact of Industry 4.0 on enterprise operational performance.Through systematically promoting learning and knowledge sharing, enterprises can achieve greater benefits in the implementation of Industry 4.0 technologies.Moreover, knowledge sharing is crucial for maintaining a long-term competitive advantage (Tortorella et al. 2020;Manesh et al. 2021).Additionally, (Li et al. 2019) pointed out that, under the context of Industry 4.0, the manufacturing industry faces increasingly complex challenges, and enterprises need to emphasize knowledge sharing and organizational learning to cope with growing market demands and competitive pressures.For SMEs, knowledge is one of the most valuable resources; through knowledge sharing, enterprises can effectively transmit internal expertise and technical skills to all employees.This not only enhances individual employee capabilities but also fosters overall innovation within the enterprise.When every employee quickly grasps new technologies and knowledge, the enterprise is more likely to adapt to market changes and anticipate new challenges (Hussein et al. 2016).Furthermore, organizational learning plays a crucial role in SMEs; organizational learning is not merely the sum of individual learning by employees but also a manifestation of collective wisdom.Through organizational learning, enterprises can effectively integrate and exchange the wisdom and experiences of various departments and teams, thereby better responding to market changes and challenges.When a good learning mechanism and culture are established within the organization, the enterprise is more likely to gain a competitive advantage (Tu and Wu 2021).Thus, the introduction of Industry 4.0 technologies has a profound impact on the collaborative culture and knowledge-sharing mechanisms of enterprises, highlighting the importance of organizational learning and knowledge management in the era of Industry 4.0 (Lepore et al. 2021).Knowledge sharing and organizational learning are crucial pathways for SMEs to enhance their competitiveness.Through the effective application of these two elements, enterprises can better cope with market changes and improve their competitiveness.

Examine the impact of promoting Industry 4.0 on the competitiveness of SMEs.

Knowledge Management
In the digital era, knowledge sharing is regarded as a key factor in promoting innovation and enhancing the performance of R&D teams.Xiao et al. (2021) proposed an evolutionary game model for knowledge sharing in R&D teams based on evolutionary game theory, exploring the evolutionary path, stable strategies, and influencing mechanisms of knowledge sharing systems.The study pointed out that the cognitive abilities of members, knowledge absorption capacity, knowledge transformation ability, knowledge innovation ability, and the complementarity of knowledge within the team promote the effectiveness of knowledge sharing in R&D teams.On the other hand, in the era of digital transformation, knowledge management is crucial for handling a large amount of available information and must lead in the generation, sharing, use, and management of relevant knowledge and information.However, existing knowledge management measures may be insufficient to promote knowledge sharing among partners, focusing too much on unidirectional knowledge flow.Therefore, digital collaboration platforms enhance the potential for bidirectional knowledge sharing (Brouwers et al. 2022).Mihardjo et al. (2019) proposed an important viewpoint that knowledge sharing and transformational leadership styles can improve team performance.Additionally, the process of creativity often begins with knowledge sharing among team members, especially in the context of sharing tacit knowledge within a specific field.Through this knowledge sharing, teams can generate numerous novel ideas, driving successful outcomes such as new products, processes, and patents.Mayastinasari and Suseno (2023) further explored the impact of transformational leadership on innovative work behavior in the digital era and the effects of transformational leadership on knowledge sharing and its influence on innovative work behavior in public organizations.Transformational leadership has a significant positive impact on innovative behavior and knowledge sharing.Knowledge sharing is crucial to an organization's success, impacting creativity, learning, and performance.Additionally, it emphasizes the influence of knowledge sharing on team atmosphere and employee life satisfaction, beyond the work itself (Ahmad and Karim 2019).García-Pérez et al. (2018) highlighted the criticality of knowledge sharing in organizational competitiveness.Their research focused on knowledge sharing within and between organizations, demonstrating through two case studies the importance of knowledge sharing for business development.Regardless of the nature of the business, individuals, groups, and decision-makers within the organization need to share critical knowledge to drive business development.These case studies emphasize the value of collaborative and human-centered knowledge sharing.Fauziyah and Rahayunus (2021) focused on the relationship between individual innovation capability and knowledge sharing, highlighting the importance of knowledge sharing in creating competitive advantages, especially supported by individual innovation capabilities.They found that individual innovation capability has a positive and significant impact on knowledge sharing and employee performance, further proving the key role of individual innovation capability in the relationship between knowledge sharing and employee performance.Nashir and Pratminingsih (2023) found that absorptive capacity positively affects knowledge sharing and job performance, with knowledge sharing acting as a mediator between absorptive capacity and job performance.Key factors for the successful promotion of knowledge management include strategy, culture, information technology, personnel, and organizational structure (Babu 2012).Information technology, knowledge management leadership, knowledge management culture, and knowledge management measurement are also important factors (Wong 2005).Additionally, organizational strategy definition, performance measurement standards, senior management involvement, and organizational culture significantly impact the successful implementation of knowledge management (Onofre and Teixeira 2022).These studies indicate that the successful implementation of knowledge management involves multiple factors, including strategy, culture, technology, personnel, and organizational structure, which collectively contribute to providing a competitive advantage for organizations.

Organizational Learning
Watad (2018) emphasized that, in IT-driven organizational changes, there is often a neglect of knowledge management and learning.They pointed out that organizations, when restructuring processes and improving productivity, tend to focus on immediate benefits while overlooking long-term knowledge management and learning strategies.This indicates that the managers' attention is usually limited and may not be able to handle both aspects simultaneously.This viewpoint reminds managers to pay more attention to the importance of knowledge management and learning in organizational change to ensure long-term development.Chuah and Law (2019) theoretically overviewed various concepts of organizational learning, describing it as the process of developing, retaining, and transferring knowledge within an organization.Although there is no unified definition of organizational learning, it is influential across many disciplines and closely related to knowledge management.Antunes and Pinheiro (2020) focused on knowledge management and learning in human resource management, emphasizing that an organization's knowledge management capabilities largely depend on its human resources, as they are the main force in creating, sharing, and applying knowledge.This underscores the importance of valuing knowledge management and learning in human resource management and viewing it as a key factor in organizational development.Hafner (2016) pointed out that the ability to effectively change and use knowledge is crucial for modern organizations.In today's era of knowledge explosion, organizations need to constantly adapt to changes and utilize knowledge to maintain competitive advantages.He emphasized the importance of incorporating organizational learning strategies into organizational development to ensure that organizations can timely absorb new knowledge and apply it in practice.Chou and Ramser (2019) proposed a multi-level theoretical model, emphasizing that organizational learning is influenced by multiple levels and sources.They suggested that employees' spontaneous behaviors (such as upward help and voice) affect organizational learning and that developing leadership capital can promote organizational learning, offering strategies to encourage employee engagement in learning behaviors.Kim and Lu (2019) discussed the literature on learning organizations and organizational performance, highlighting the importance of learning organizations in improving organizational performance.They stated that the ability of learning organizations to connect with the external environment and the presence of leadership that supports learning enable these organizations to better cope with changes and challenges, maintaining a leading position in competitive environments.Seman and Mohamad (2019) emphasized the role of organizational learning in promoting corporate innovation.Organizational learning helps organizations to continuously develop new ideas and solutions, thereby enhancing innovation capabilities.The study further pointed out that introducing transformational leadership styles helps to motivate employees to actively participate in the learning process, thereby driving innovation.Argote et al. (2020) divided organizational learning into four processes: searching, knowledge creation, knowledge retention, and knowledge transfer.This perspective provided a more detailed exploration of the processes and influencing factors of organizational learning.Through these four processes, organizations can continuously acquire new knowledge, create value, retain important information, and share knowledge within the organization.Olejarski et al. (2019) explored the importance of organizational learning from the perspective of public sector organizations, highlighting that organizational learning requires public institutions to change their norms and policies to better meet the changing demands and challenges.You et al. (2021) proposed organizational learning as a strategic approach to organizational change, emphasizing the importance of learning organizations in coping with change challenges and achieving organizational goals.Namada (2018) regarded organizational learning as a key source of competitive advantage for contemporary business organizations, exploring different elements of organizational learning, including knowledge acquisition, knowledge distribution, information interpretation, and organizational memory, and how these elements influence organizational competitive advantage.Pham and Hoang (2019) confirmed the positive impact of organizational learning capabilities on business performance.They particularly found a positive correlation between management's commitment to learning, knowledge transfer, and business performance, encouraging companies to enhance business performance by strengthening organizational learning capabilities.Elkjaer (2021) explored the theoretical construction of organizational learning, discussing the debates on the responsibility of organizational learning between practitioners and researchers, and suggested adopting a pragmatic learning theory to resolve these disputes.This study provided valuable insights into the future development of the field of organizational learning.Key success factors for organizational learning include strategy, culture, and technological factors (Mas-Machuca and Martínez Costa 2012).Organizationallevel strategies and policies, IT readiness, performance and impact evaluation, personnel skills and expertise, and data quality are also critical to success (Clark et al. 2020).Moreover, organizational learning, as a strategic tool, not only enhances employees' knowledge and skills but also promotes organizational development and growth, creating a dynamic learning organization that plays an important role in achieving knowledge management and organizational goals (Saadat and Saadat 2016).Support from senior executives is equally crucial, as their participation and commitment can ensure the smooth progress and successful implementation of organizational learning and knowledge management programs (Onofre and Teixeira 2022).

(2020) believe that Industry 4.0 is a new model of technological system automation, based on the technological integration of the smart manufacturing concept, including the application of information and communication technologies such as cloud computing, big data analytics, artificial intelligence, and distributed control.They point out that ERP systems are evolving and can connect to IoT, big data analytics, AI, and cloud computing.Polívka and Dvořáková (2021) emphasize the significant impact of Industry 4.0 on the IT environment of organizations, especially ERP systems.Rathnayake et al. (2022) stress that Industry 4.0 technologies will increasingly rely on the application of ERP systems.Integrating Industry 4.0 technologies, such as IoT and RFID, into ERP systems can enhance ERP capabilities, providing more accurate analysis and forecasting.Skrzeszewska and Patalas-Maliszewska (2019) mention that Manufacturing Execution Systems (MES) are tools for executing internal business processes, particularly notable in the automotive manufacturing industry.Based on examples from two automotive manufacturing companies, they analyze the effectiveness of MES usage by maintenance department employees across business, tactical, and strategic management levels.Govender et al. (2019) explore the integration challenges between ERP and MES systems in the steel industry, which needs to integrate manufacturing and business systems for real-time decision-making and increased visibility of production processes.Additionally, the combination of MES and PLM systems can accelerate the promotion of Industry 4.0 (D'Antonio et al. 2017).Popescu and Scarlat (2022) discuss the need to integrate new paradigms of industrial automation and control systems in Industry 4.0 management.They examine the synergy of two concepts: cyber-physical SCADA systems and human-centric production, emphasizing their complementarity.This study highlights the role of SCADA systems in Industry 4.0 transformation.Malik et al. (2021) mention the construction modules of Industry 4.0, including cyber-physical systems, AI, robotics, cloud computing, and IoT, noting that SCADA systems play a key role in Industry 4.0 by monitoring, collecting, and processing real-time data to control industrial manufacturing processes.Chang et al. (2021) emphasize the importance of the SCADA architecture for achieving smart interconnected manufacturing factories, proposing a cloud-based analytics module for predictive maintenance (PDM) in Industry 4.0, using machine learning algorithms to analyze preprocessed data and provide predictive recommendations for production quality management.Saxby et al. (2020) point out how lean management methods support continuous improvement in the field of Industry 4.0.Lean management supports factors in Industry 4.0, including continuous improvement, supply chain involvement, pull systems, and customer-centric approaches.This study identifies that lean management can be supported by Industry 4.0 technologies.Abdulnour et al.

Research Subjects
This study targeted the Taiwanese metal industry SMEs as the research population.According to the Ministry of Economic Affairs of Taiwan, the upper limit for the number of employees in SMEs is 200.According to the statistics from the Department of Statistics, Ministry of Economic Affairs, Taiwan, there are 23,000 registered metal industry companies in Taiwan, of which 95% are SMEs.

Data Collection
The survey period for this study was from March 2024 to April 2024.To ensure that the respondents were representative and indicative of the industry, the survey questionnaires were distributed to members of relevant associations in the Taiwanese metal industry.For a comprehensive and reliable survey, the survey was sent via email to senior executives (managers of the management department, HR department, manufacturing department, or R&D department).Responses were collected through an online Google form, yielding a total of 129 valid samples with a response rate of 24%.

Survey Design
Based on the collected literature, indicators were designed to explore knowledge management, organizational learning promotion, Industry 4.0, and competitiveness.Three experts from relevant fields were invited to provide expert opinions, which helped to establish a valid questionnaire for this study.The questionnaire covers the company background as defined in Table 1.The survey items for this study included promoting knowledge management and organizational learning, with Industry 4.0 divided into operational management, smart production applications, and information and data applications.Competitiveness was divided into "business performance and production performance."A Likert five-point scale was used, with responses ranging from "strongly agree" (5), "agree" (4), "neutral" (3), "disagree" (2), to "strongly disagree" (1).Higher scores indicate a higher degree of actual conformity to the situation.A pilot survey was conducted, yielding 14 responses, and a Pearson correlation analysis was performed.The results show significant correlations between promoting knowledge management, organizational learning, Industry 4.0, and competitiveness, forming the basis for the full survey.

Data Processing and Statistical Methods
After collecting the survey data, all valid responses were coded and entered into a computer database.For statistical analysis, SPSS for Windows version 27 was used.The following statistical analyses were conducted: 3.5.1.Dimensional ANOVA Analysis Business operations were used as the independent variables, divided into employee numbers, company revenue, and export.Knowledge management, organizational learning promotion, Industry 4.0, and competitiveness were used as the dependent variables.A one-way ANOVA was conducted.If significant differences were found, Scheffé's post hoc comparisons were performed to understand the differences.

Pearson Correlation Analysis
We used a correlation analysis on each dimension of knowledge management, organizational learning promotion, Industry 4.0, and competitiveness to understand the relationships between the variables.

We used simple regression models to examine the relationship between Industry 4.0 and competitiveness.

ANOVA Method Analysis
In the ANOVA analysis of the employee numbers on the four variables (Table 2), the results show significant impacts on knowledge management promotion, organizational learning promotion, and Industry 4.0, but no significant impact on competitiveness.Knowledge management promotion has a significant impact (p < 0.01**), with the post hoc comparison results indicating that the third group scored higher than the first and fourth groups.Organizational learning promotion has a significant impact (p < 0.05*), with the post hoc comparison results showing that the third group scored higher than the second, fourth, and first groups.The introduction of Industry 4.0 has a significant impact (p < 0.01**), with the post hoc comparison results indicating that the third group scored higher than the fourth, second, and first groups.In terms of competitiveness, there is no significant impact (p = 0.284); this can be explained by the fact that competitiveness is a part of overall corporate performance indicators, and it is unlikely to show significant differences solely based on the number of employees.The ANOVA analysis of company revenue on the four variables (Table 3) shows that there are highly significant impacts on knowledge management, organizational learning promotion, and Industry 4.0, while the impact on competitiveness is relatively lower but still significant.Specifically, knowledge management promotion has a significant impact (p < 0.01).The post hoc comparison results indicate that the third group scored higher than the fourth, first, and second groups.Organizational learning promotion has a very significant impact (p < 0.001).The post hoc comparison results show that the third group scored higher than the fourth and first groups.The introduction of Industry 4.0 has a highly significant impact (p < 0.001).The post hoc comparison results indicate that the fourth group scored higher than the third, first, and second groups.In terms of competitiveness, there is a significant impact (p < 0.05).The post hoc comparison results show that the fourth group scored significantly higher than the third, second, and first groups.In the ANOVA analysis of the export ratio on the four variables (Table 4), the results show no significant impact on knowledge management promotion, organizational learning promotion, and Industry 4.0.Specifically, the p-value for knowledge management promotion is 0.496, for organizational learning promotion is 0.154, and for the introduction of Industry 4.0 is 0.120, indicating that the export ratio does not have a significant impact on these three variables.However, for competitiveness, the p-value is 0.004, indicating a significant impact.The post hoc comparison results show that the fourth group scored significantly higher than the third, second, and first groups; this can be explained by the fact that companies with higher export levels generally have higher-value products, which in turn can enhance their competitive advantage.

Pearson Correlation Analysis
The results of the product-moment correlation analysis between knowledge management promotion, organizational learning promotion, operational management, smart production applications, information and data applications, business performance, and production performance are shown in Table 5.The following is a brief description of the correlations between variables and their significance levels: Knowledge management and organizational learning show a strong positive correlation (r = 0.562, p < 0.001).Knowledge management has significant correlations with operational management (r = 0.430, p < 0.001), smart production applications (r = 0.207, p < 0.05), business performance (r = 0.346, p < 0.001), and production performance (r = 0.211, p < 0.05).There is no significant correlation with information and data applications (r = 0.168).
Smart production applications and information and data applications show a strong positive correlation (r = 0.687, p < 0.001).There are significant correlations with business performance (r = 0.491, p < 0.001) and production performance (r = 0.449, p < 0.001).
Information and data applications and business performance show a strong positive correlation (r = 0.526, p < 0.001), and a significant correlation with production performance (r = 0.456, p < 0.001).

Conclusions
The metal industry in Taiwan is composed of 95% small-and medium-sized enterprises (SMEs).The metal industry chain is extensive, covering upstream, midstream, and downstream sectors, including steel, hand tools, casting, fasteners, plumbing hardware, surface treatment, and heat treatment.These enterprises are generally small scale and operate with a specialized division of labor.Therefore, for enterprises to promote transformation, upgrade, and enhance competitiveness through the introduction of new technologies, it is necessary to simultaneously promote knowledge management and organizational learning.The findings of this study can be summarized as follows: 1.
Through this study, it was observed that companies with relatively high organizational learning promotion and Industry 4.0 significance tend to have higher revenues.This can be explained by the fact that a higher degree of organizational learning promotion helps companies to apply more new technologies or enhance R&D capabilities, thus driving revenue growth.Similarly, companies with a higher degree of Industry 4.0 adoption can leverage production technology advantages to increase revenues.This result aligns with global government policies and resources supporting enterprises in adopting Industry 4.0 technologies to aid in transformation and sustainable operations.Furthermore, it was observed that knowledge management promotion, organizational learning promotion, and Industry 4.0 adoption do not significantly impact export proportions, except for competitiveness.Companies with higher export proportions tend to have market advantages in their products, thereby enhancing business performance and production efficiency.Regarding the number of employees, significant impacts were found on knowledge management promotion, organizational learning promotion, and Industry 4.0 adoption, especially in groups with 51-75 employees.This suggests that reaching a certain scale in the number of employees can facilitate the establishment of knowledge management and organizational learning mechanisms.For Industry 4.0 adoption, companies with 51-75 and over 76 employees have higher adoption levels, indicating that the scale of the workforce affects the extent of Industry 4.0 adoption.

2.
The transformation and upgrading of SMEs can enhance competitiveness, with Industry 4.0 adoption being a global industrial development trend.Regarding the correlation between knowledge management and the three aspects of Industry 4.0, operational management had the highest correlation, followed by intelligent production applications, while information and data applications showed no significant correlation.This study's findings are consistent with those of Bettiol et al. (2022), showing that knowledge management can influence operational management and intelligent production applications.However, unlike their findings, this study did not find a significant impact on information and data applications, possibly because this study focused on SMEs that have already adopted operational management and intelligent production technologies, leading to more knowledge sharing and exchange within the organization.

3.
Promoting organizational learning can enhance the technological capabilities and competitiveness of SMEs.This study observed that organizational learning can facilitate the adoption of relevant technologies in the three aspects of Industry 4.0: operational management, intelligent production applications, and information and data applications.The findings are consistent with those of Srivastava et al. (2022) and Prashar et al. (2024), indicating that a comprehensive learning mechanism within the organization, supported by senior management, is crucial for transformation and upgrading.Organizational learning can serve as a key strategy for promoting enterprise transformation and accelerating the upgrading process.4.
The adoption of Industry 4.0 technologies is an optimal tool for SME transformation, enhancing business performance and production efficiency.The findings of this study are consistent with those of Lavinsaa et al. (2020), Calış Duman and Akdemir (2021), and Chauhan et al. (2021), which show that promoting Industry 4.0 can enhance competitiveness.Competitiveness is key to the sustainable operation of enterprises, leading governments to invest resources in supporting SMEs to adopt Industry 4.0, thereby driving sustainable national industrial development.
In summary, knowledge management and organizational learning can drive enterprises to adopt Industry 4.0.This study finds that SMEs need to establish a short-, medium-, and long-term transformation roadmap with set goals and benefits for each stage to verify if the transformation meets the expected goals.For SMEs to adopt new technologies such as Industry 4.0, they need to fully utilize these technologies as a strategy to enhance competitiveness.Promoting knowledge management is crucial, as the dissemination and application of new knowledge within the organization is key to SME transformation.Internalizing new knowledge among employees facilitates the expected benefits of new technology adoption.Promoting organizational learning is also critical for new technology adoption within the organization, thereby enhancing competitiveness.Hence, promoting knowledge management and organizational learning effectively drives Industry 4.0 adoption, enhancing competitiveness, aligning with the research objectives, and serving as a strategy for future technology adoption to ensure successful transformation and sustainable operation.

Research Limitations
The limitations of this study include the fact that Industry 4.0 has become a global industrial development trend, yet this study is limited to a single country, Taiwan, and a single industry.The Taiwanese government prioritizes Industry 4.0 as a key policy for industrial transformation, providing enterprises with substantial resources and reducing obstacles to Industry 4.0 adoption.

Future Research Recommendations
As Industry 4.0 has become an industrial development trend, future research and surveys should expand the industry scope and conduct comparative analyses across different industries.Further investigation is needed to explore whether the transformation promotion results differ across industries and countries with varying background factors.
Additionally, knowledge management, organizational learning, and Industry 4.0 involve changes in business strategies and technology applications.Future research should explore the key success factors and obstacles in promoting these three aspects simultaneously.
