1. Introduction
Small and medium enterprises (SMEs) make a significant contribution to development and community welfare. However, SMEs face challenges, namely high levels of competition and market demand [
1,
2]. To survive in the competition, SMEs need competitive advantages [
3,
4]. Stimulating innovation [
5] and innovative work behavior (IWB) [
6] are ways to achieve competitive advantages. Currently, there is an emerging interest in studying innovation, especially IWB [
7,
8,
9], which is considered important in facilitating organizational performance [
10,
11,
12,
13]. However, SMEs cannot yet achieve innovation. In economic theory, SMEs still have several limitations, such as labor, finance, and small market scope [
14]. All results in SMEs not having the ability to invest in technology as a driving factor for accelerating innovation [
15]. On the other hand, SMEs must continue to strive to find ways to strengthen their competitive position and productivity [
16].
In general, innovation is the ability of an organization to optimize assets and capabilities that aim to change the work results achieved [
17,
18]. In the development organization, innovation is emphasized in product innovation and process innovation [
19]. Limited financial capacity results in reduced process innovation in SMEs [
20], while product innovation is largely determined by the skill level of the workforce [
21]. Previous studies have shown that TL has an impact on the development of innovation, which does not occur under traditional leadership [
22]. TL substantially influences a company’s ability to be more responsive when creating products and carrying out process innovation to generate efficiency [
23]. As is known, knowledge that supports organizational characteristics can be achieved through knowledge-sharing practices and the employee empowerment process. Thus, investigations continue to be carried out to examine the influencing variables [
24].
In the last few decades, scholars have identified leadership success in increasing IWB, i.e., transformational leadership (TL) [
25,
26]. TL was initially outlined by Bruns (1978) [
27], which was later extended by Bass (1985) [
28] by elucidating the psychological mechanisms underlying it. TL has progressed and proven to be impactful in increasing positive organizational identification [
29]; organizational commitment [
30,
31]; organizational culture [
32,
33]; knowledge sharing [
26,
34]; creativity [
35]; and IWB [
1,
36]. Nonetheless, different findings were demonstrated in [
37], which reports that TL does not positively affect IWB. Thus, it is crucial to investigate the linkage between TL and IWB, which remains underdeveloped in the SMEs context, given that SMEs require IWBs to deal with a dynamic environment [
38].
Therefore, the investigation of the relationship between TL and IWB needs to be carried out based on several considerations. First, it is important to find out the level of understanding of TL in SMEs, because it will be difficult to improve work behavior if leaders do not support it. Second, Bednall et al. (2018) [
39], in their study, proposed that TL is categorized into three levels, namely low, medium, and high. If TL is perceived as low, the impact shown tends to be negative. Therefore, this comprehensive study provides conceptual insight into the important role of leaders, especially in regard to TL, which has a good impact on organizations [
40]. On the other hand, SMEs are businesses that are often managed using traditional management, which ignores the managerial aspects that apply to large businesses. This is characterized by the difficulty of distinguishing between leadership and ownership. Usually, the owner directly acts as a decision-maker. Therefore, it is very possible for absolute decisions to occur, which hurts SMEs. Like SMEs in the field of handcrafts, the owner or manager develops products by involving designers from outside the SME, and employees are only tasked with making products based on the examples given. In other words, employees are not involved in product development, meaning that IWB is only carried out on work-related technical matters. All of this influences how management practices, such as production and other operations, create ambiguity and social complexity. Employees can become more growth-oriented when they are faced with more challenging work that makes them want to develop their thinking and authority [
41,
42]. For this reason, it is very possible to introduce the concept of transformational leadership to owners in managing SMEs. Moreover, SMEs are currently faced with tight competition, requiring them to formulate strategies through leadership that can accommodate visions and goals.
Therefore, psychological empowerment (PE) was proposed to facilitate the relationship between TL and IWB [
40,
43]. Traditionally, empowerment is an opportunity to decide [
44,
45]. In this regard, it has been argued that IWB occurs through empowerment, as employees who are involved in the decision-making process and have the opportunity are more likely to contribute. Therefore, PE is predicted to stimulate employees’ innovative abilities [
40]; when subordinates are psychologically empowered, they will be autonomously driven to display innovative behavior [
44]. However, unlike what is happening in SMEs today, SME management does not provide employees with the opportunity to contribute to product and process development. Employees in this area tend to act as implementers of the development results that must be carried out. SMEs are supported by employees who are skilled in their fields. Thus, if PE is achieved by providing employees with the opportunity to contribute, it is also predicted to be able to mediate TL and IWB [
44,
46].
Several studies also report that knowledge sharing (KS) makes a significant contribution to increasing IWB [
47,
48,
49,
50,
51]. For example, Vandavasi et al. (2020) [
52] reveal that KS directly and indirectly affects leadership development and IWB. KS process produces innovative work behavior [
53]. Further, organizational drive for knowledge acquisition can promote, generate, and realize innovative ideas [
54]. Therefore, leaders must improve KS practices to achieve competitive advantage through IWB.
This study was conducted on export SMEs in Bali with several considerations. First, SMEs provide employment and are a source of income, especially for developing countries, such as Indonesia. In addition, export SMEs have also been proven to make important contributions to their countries in recent decades.
Second, export SMEs face increasing competition along with global economic growth, so increasing innovation capacity could be a solution for SMEs. However, measuring innovative work behavior has so far tended to be carried out in large companies. Third, a study is needed on innovation from the perspective of SME employees [
55]. The achievement of employee innovative behavior can likely be carried out with TL, because of their ability to interact with subordinates [
2,
56]. In addition, innovative behavior requires other supporting factors, such as knowledge [
57] and empowerment [
43]. These reasons are the foundations for why further investigation is needed.
5. Discussion
Organizations require leaders to empower and practice KS to advance economic growth in developing countries like Indonesia. This study scrutinizes whether TL can encourage empowerment, knowledge, and enhance innovative behavior. Through improving innovative behavior, organizations can attain a sustainable competitive advantage. This study examines the linkage between TL and IWB in SMEs. The findings of this study are explained as follows.
First, the findings report that TL does not affect IWB. The finding explains that the increase in TL practices does not increase IWB. These findings support previous studies [
37,
39,
129,
130], confirming that SMEs do not adopt modern management practices, unlike large companies. Thus, practices related to management, i.e., leadership, have yet to show a significant impact because SMEs adhere to the kinship principle. Consequently, the closeness factor is established from the start, influencing task delegation and accountability. The industrial scale also does not regulate bureaucratic distance between leaders and subordinates—considering SMEs with talented employees. Moreover, the craft industry employees’ skills are adequate for establishing IWB. Therefore, IWB is well accommodated without the demand for a specific type of leadership. Bednall et al. (2018) [
39] report that TL may not affect IWB since the implementation of TL still requires improvement.
These findings show that innovation in SMEs must maximize external factors through an open innovation system [
131]. Through open innovation activities, it is related to innovation performance [
132]. Open innovation can be a solution for SMEs to overcome the limitations of their resources [
133]. Where this evidence has been discussed previously, such as by Mount and Martinez (2014) [
134], it can be seen that companies involved in open innovation directly gain knowledge from external partnerships and alliances from the results of the innovation that are carried out. Open innovation is another step for leaders to increase innovative behavior. In other words, open innovation can be facilitated by involving potential partners and creating a development and training program for SMEs. Similarly, open innovation provides a framework that allows for the comparison of social interventions across sectors in socio-economic and institutional contexts [
135].
In addition, the application of open innovation can be a step in encouraging traditional management to be more innovative, so that organizational management becomes better [
136,
137]. Open innovation practices can also provide SMEs with the opportunity to overcome the limitations they have, i.e., related to resources, finance, and business [
138].
The inability of TL to increase innovation is inseparable from the organizational structure of SMEs, which is relatively simple, unlike that of large businesses. This can be seen from the absence of an HR management system [
139], resulting in the innovative behavior designed by TL receiving less attention. All of this is inseparable from ownership, which often ignores how TL efforts can contribute to increasing innovative behavior. Previous findings have stated that the decision to invest in HR is an important factor in increasing organizational capacity [
140].
Second, TL significantly increases PE and KS, which indicates that the better TL is, the more PE and KS is present in SMEs. To survive increasingly fierce competition, joint efforts are required. This result supports previous studies that mention that TL increases PE [
84,
87,
88] and elevates KS practices [
26,
34,
82,
83]. Leaders can optimize subordinates’ roles by performing PE and encouraging KS. Therefore, leaders who empower employees and facilitate KS help SMEs survive amid competition.
Third, KS and PE significantly and positively affect IWB. This finding demonstrates that the better the empowerment and the higher the KS, the more IWB increases. This study confirms the results of previous studies that reveal that PE increases IWB [
44,
50,
93,
96]. KS similarly impacts IWB [
1]. Efforts to increase IWB in SMEs must include empowerment and knowledge. PE can be an intrinsic motivation for employees [
114], while KS is vital to acquiring new knowledge [
141]. Both are able to increase innovative behavior.
Fourth, the proposed research model includes the mediation of KS and PE. Our research discovered that PE mediates TL and IWB. This finding confirms the results of previous studies that report that PE intervenes in the linkage between TL and IWB [
40,
74,
142], especially regarding employees’ way of thinking [
10]. These findings expand on previous studies by Sudibjo and Prameswari (2021) [
37] and Bednall et al. (2018) [
39] by incorporating PE in the linkage between TL and IWB. Moreover, these findings demonstrate that employees must be adequately empowered beyond their roles as recipients and operational executors. Thus, PE drives them to be more motivated when improving their performance by showing innovative behavior.
Subsequently, our research demonstrates that KS mediates TL and IWB. These findings confirm the results of previous studies [
1,
26,
37].
This verifies that leaders need to facilitate KS to be more innovative in their work. Moreover, KS regulates IWB in SMEs, especially in developing countries like Indonesia. Leadership with a transformational approach encourages subordinates to share more knowledge, information, skills, and expertise, which impacts the increase in innovation [
87]. Moreover, knowledge supports leaders when encountering environmental changes and acquiring new information to seize opportunities efficiently [
38]. Thus, this study fills in the gaps in the findings of Sudibjo and Prameswari (2021) [
37] and Bednall et al. (2018) by revealing when, how, and why TL can be linked to IWB.
The success of an organization in achieving innovation is certainly determined by the characteristics of the organization itself. Like start-ups, they need supporting factors for innovation, i.e., leadership, technology, knowledge, and support from the environment [
143,
144,
145]. Similar factors are also found in innovative companies that prioritize leadership to solve existing problems, although they do not completely ignore other aspects that support business development [
146]. In addition, employee development policies and procedures are an investment for innovation [
147]. In contrast, spin-off companies need innovation to explore opportunities [
148], and leadership is needed to build a team to achieve this [
149]. Looking at the comparison of innovative companies, spin-offs and start-ups have different orientations towards innovation and leadership. However, in general, all types of companies need innovation and leadership to improve their business performance. Thus, if SMEs want to remain competitive, they must separate management and ownership. The goal is to increase competitiveness and achieve business sustainability. Although SMEs currently have various limitations, innovation can be achieved through open innovation involving partnership programs.
6. Conclusions
First, TL does not encourage IWB. This finding indicates that SMEs’ adoption of TL remains low. Second, TL supports employees KSe and has been proven to be successful in PE through increasing intrinsic motivation. Third, KS and empowerment influence IWB. This indicates that employees’ KS practices help them to be more innovative at work. Empowered employees are more motivated and tend to demonstrate innovative behavior at work. Fourth, KS and PE mediate TL and IWB. Thus, KS and PE bridge transformational leaders in incorporating IWB. Consequently, SME leaders must contribute to KS and PE to influence employees, especially in terms of advancing work behavior.
This study also has several limitations. First, the sample size was limited to export SMEs in Bali, Indonesia. When considering the number of export SMEs in Indonesia, the sample size of 38 is relatively small. As Indonesia has a variety of cultures and regional potentials, this results in existing SMEs having their own uniqueness that influences their type of business. Several regions in Indonesia have agricultural potential, so the products produced are often natural. Meanwhile, craft SMEs in other provinces prioritize the production of ornaments, as a result of local skills and capabilities. These differences determine how the routine and strategic processes are implemented by leaders/owners in management [
150]. So, this requires researchers to be careful in generalizing these results. Therefore, the number of samples is our main limitation and allows us to only analyze certain sectors under the conditions that occur. It is thus important to conduct similar studies involving other sectors in order to offer broader results with larger sample sizes or in other domains. Second, this study is cross-sectional; thus, the information obtained over a certain period and the contingent effects cannot be confirmed. Therefore, future research should be carried out as longitudinal studies [
151]. This is because longitudinal research can test the dynamic nature of constructs, and thus researchers can focus on changes that occur in the observed construct, not only on the representation of the measured construct [
152]. In this way, researchers can gain knowledge related to changes that occur over time and changes following the predictions made [
153]. This is a gap that can be filled by future research through longitudinal studies. Third, TL does not affect IWB. Therefore, these findings can be used to underpin future studies in order to explore the role of TL in enhancing SME employees’ IWB.
6.1. Theoretical Implications
This study examines the role of TL in KS, PE, and IWB. Thus, this study provides several theoretical contributions. First, TL does not directly affect IWB. However, TL mediates KS and PE. It is inseparable from KS and PE, which directly increase IWB. These results provide an altered perspective of SET. These findings indicate that TL does not determine IWB because employees perceive that social exchange is a driving force for deciding work behaviors. Second, KS and PE mediate the linkage between TL and IWB. These results indicate that leaders can encourage KS practices and foster psychological empowerment in employees to increase IWB.
6.2. Practical Implications
There are several managerial implications for managers and employees. First, managers must better understand and develop TL in business management, especially in export SMEs, in order to produce IWB. All of this is in accordance with the theory of social exchange, where social interactions that are built into the company can connect managers with their subordinates. Second, leaders are required to facilitate KS so that employees become more innovative when carrying out their jobs. Knowledge can be achieved by providing training and development, forming work groups, and undertaking other activities that make it easy for them to exchange information. Third, a manager must improve PE. The empowerment that is achieved can increase employee confidence so that they become more effective in their work. In addition, they may seek and find innovative steps in the completion of their work. Finally, based on the employee perspectives, KS and PE are needed and can be a strategic step in increasing employee competence and trust in managers and the company.
