This research proposes and validates  
a
model  
hypothesizing the relationships between social capital and  
knowledge sharing in the public sector. We employed a survey  
design using a questionnaire to collect data utilizing a convenient  
sampling method. The study gathered 389 questionnaires from  
civil servants and officials working in departments and agencies  
in the public sector in Tien Giang province. The research  
hypotheses were developed and validated using the Structural  
Model Modeling (SEM) approach. The research results show that  
all hypothesized relationships were confirmed except the link  
between structural social capital and tacit knowledge sharing.  
Our study can be considered a pioneering study to investigate the  
influence of social capital on both tacit knowledge sharing and  
explicit knowledge sharing in the public sector. This work also  
enriches the growing body of knowledge regarding social capital  
and knowledge sharing in the public sector. Our research also  
offers suggestions to leaders in the public sector concerning  
relevant measures and policies that enable employees to share  
knowledge by promoting social capital.

1. Introduction  
Over the last few years, public and private organizations have shown increased interest in  
managing knowledge and human resource. Knowledge sharing is increasingly important, not  
only as a means to obtaining personal benefits but also as a vehicle for improving the  
performance of both individuals and organizations (Kim & Lee, 2005). While there are widely  
recognized agreement that there are various ways that societies can gain knowledge, those  
communities that leverage social capital are acknowledged as the main vehicles by which this  
knowledge is made available (Chow & Chan, 2008; Kim & Lee, 2010). Furthermore, several key  
factors influencing knowledge sharing and creation include social dynamics that stem from each  
individual and group’s interpersonal and group relationships (Van den Hooff & Huysman, 2009).  
Studies on social capital and knowledge sharing have investigated the influence of social  
networks and shared goals on knowledge sharing attitudes. This indirect effect on knowledge  
sharing intention has been documented by researchers like Chow and Chan (2008), who assert  
that social networks and goals have a substantial impact on knowledge sharing attitudes.  
Ganguly, Talukdar, and Chatterjee (2019) found that social capital (both cognitive and  
relational) are important prerequisites for sharing tacit knowledge, impacting organizational  
innovation capability. Hau, Kim, Lee, and Kim (2013) argue that social capital affects the intent

75  
to disseminate explicit knowledge and tacit knowledge (TN). Zaqout and Abbas (2012)  
demonstrate the role of trust and social networks in promoting explicit knowledge and TN  
exchange as well as in developing tacit knowledge and improving work performance.  
It is critical to discern the various influences on employees’ desire to disseminate  
knowledge, which aids in enhancing the sharing of information between public-sector employees  
and agencies. Since there is so much research about organizational knowledge sharing, some of  
the variables may influence knowledge sharing in organizations. However, the majority of studies  
have examined knowledge sharing in the private sector. To date, there are limited studies that  
have examined knowledge sharing in the public sector (Amayah, 2013). Public organizations and  
knowledge-based organizations are known as public-sector organizations today (Willem &  
Buelens, 2007). Firms in the private sector, as well as government agencies, must therefore see  
that information is as critical to their organizations as it is to the businesses in the private sector  
(Willem & Buelens, 2007). To meet more demanding competition for resources and services,  
public organizations are challenged now more than ever before (Luen & Al-Hawamdeh, 2001).  
The importance of developing processes to improve knowledge sharing cannot be overstated:  
These processes will enable current employees to learn from and benefit from the knowledge and  
experience of their senior colleagues prior to retirement (Amayah, 2013).  
Knowledge management in the public sector in Vietnam tends to move slower than in the  
private sector. Specifically, public organizations do not have effective mechanisms and solutions  
to encourage civil servants and public employees to create and share knowledge. They turn each  
individual’s ability into the organization’s knowledge and the civil service to bring advantages  
and operational performance to them. Furthermore, no study has looked specifically at social  
capital dimensions and knowledge sharing relationships, including explicit knowledge sharing  
and tacit knowledge sharing in the public sector. Such a comprehensive examination of these  
relationships would address that research gap. The specific objective of this work is to study the  
link between the social capital dimensions and knowledge sharing among individual members in  
the public sector.  
2. Literature review and hypotheses development  
Social capital is effectively a theory appreciating ‘it’s not what you know, but who you  
know’ and developed on the strength of weak ties, as defined by M. S. Granovetter (1973).  
According to this theory, resources accessed through weak ties will be more valuable than those  
accessed through stronger relational ones. This was explained by developing strong ties between  
similar individuals who, by definition, would have similar contacts and thus access to similar  
resources.  
Nahapiet and Ghoshal (1998) were instrumental in establishing social capital as a valid  
construct within management research, proposing a model of social capital composed of a  
number of components that could be used to explain both micro- and macro-level behavior of  
individuals and groups. The model classified the concept into three distinct components:  
cognitive, structural, and relational, all of which will be discussed in greater detail in the  
following sections. While the preceding emphasizes that social capital theory’s primary purpose  
was to provide insight into obtaining valuable resources, it may also serve as a control  
mechanism and help explain how communities behave.  
2.1. Social capital dimensions  
Social capital is defined as “the sum of the actual and potential resources embedded  
within, available through, and derived from the network of relationships possessed by an  
76  
Ha M. Tri, Doan B. Son. HCMCOUJS-Social Sciences, 11(1), 74-88  
individual or social unit” (Nahapiet & Ghoshal, 1998, p. 243). Adler and Kwon (2002)  
conceptually constructed a model of social capital that classifies the various forms, origins, and  
effects of the concept. They defined social capital as “the goodwill available to individuals or  
groups whose source is found in the structure and content of a person’s social relations” (p. 23).  
Furthermore, social capital can be categorized into three interrelated components: structural,  
relational, and cognitive (Nahapiet & Ghoshal, 1998).  
Social capital can be defined as the number of networks a person or group maintains or  
the network composition of an organization. It is viewed through a network’s size, the number of  
network ties, and stability (Inkpen & Tsang, 2005). Cognitive social capital is defined as the  
collective knowledge and awareness possessed by people that allows them to form an agreement  
and identify patterns and patterns across participants (Nahapiet & Ghoshal, 1998). For one facet  
of the dimension, we have mutually agreed upon goals and a network culture that members  
participate in (Inkpen & Tsang, 2005). While in relational social capital, we focus on the way  
actors’ personal ties are connected to relational outcomes of interactions, we are interested in  
structural results of interactions. Previous research, for example, that of Hau et al. (2013), has  
shown that the significant role of social ties, shared goals, and social trust in social capital are  
corroborated by further analysis.  
2.1.1. Structural social capital and relational social capital  
A relationship (as opposed to the material) holds structural social capital, which is  
presented in social interaction ties. These ties help increase trust, called relational social capital  
(Tsai & Ghosal, 1998). Research conducted previously has asserted that social interaction  
appears to be the foundational building block for forming trusting relationships (M. Granovetter,  
1985). The intimate connection grows between the two actors as they divulge personal  
information over time, and as this happens, the actors will discern each other as trustworthy  
(Gabarro, 1978). Actors can learn about and relate to one another through frequent and close  
social interactions, obtain relevant information, and collectively form a common viewpoint. As a  
result, when an actor occupies a central position in a social interaction network, he is more likely  
to be perceived as trustworthy by the network’s other actors (Tsai & Ghosal, 1998). Therefore, it  
is relevant to formulate the hypothesis as below.  
H1: Structural social capital will be positively related to relational social capital  
2.1.2. Cognitive social capital and structural social capital  
The relationship between structural social capital and cognitive social capital is predicated  
on the premise that social interaction is critical in configuring common goals and values and  
enabling an organization to communicate these goals and values (Tsai & Ghosal, 1998). To study  
cognitive accuracy in the minds of individuals, Krackhardt (1990) performed a comprehensive  
investigation of the entire organizational social structure and found the structure of members’  
social interactions has an impact on the formation of a shared vision. Many aspects of  
organizational socialization (such as informal social interaction) have been described in terms of  
organizational values in the literature (Van Maanen & Schein, 1979). Actors understand and  
adopt the language, codes, values, and practices of their organizations as a result of acting in  
accordance with the concepts that arise from social interaction. However, these actors could also  
generate new values and new perspectives that they have in common as well as entirely new  
visions relying on their shared interests and understandings. Units within a multi-building firm  
may have various interests and goals, but those goals and interests may differ from those of other  
units within the corporation. An individual member of a unit can have a collective orientation that  
aligns with the goals and plans they pursue (Tsai & Ghosal, 1998). Accordingly, we propose:

77  
H2: Structural social capital will be positively related to cognitive social capital  
2.1.3. Relational social capital and cognitive social capital  
By supporting and enhancing a group’s shared values and showing a clear common  
vision, the cognitive dimensions of social capital can encourage people to form trusting  
relationships (Tsai & Ghosal, 1998). The kind of relationship one develops with someone who  
trusts you indicates that “Common goals and values have brought and kept them together”  
(Barher, 1983, p. 21). In the view of Ouchi (1980, p. 138), “Common values and beliefs provide  
the harmony of interests that erase the possibility of opportunistic behavior”. As Sitkin and Roth  
(1993) asserted, there is a positive relationship between trusting relationships and value  
congruence; that is, people’s values and the organization’s values are similar. Using a  
cooperative framework and goal, individuals within the organization tend to trust each other, as  
they can expect that everyone is working toward a cooperative framework (Tsai & Ghosal,  
1998). Therefore, it is appropriate to formulate the hypothesis as follows.  
H3: Cognitive social capital will be positively related to relational social capital  
2.2. Social capital and knowledge sharing  
Structural social capital consists of relationships, density, configuration, and network  
relevance (Nahapiet & Ghosal, 1998). Network relationships allow access to resources  
embedded in social relationships, and knowledge is by far the most precious asset embedded in  
that relationship (Ganguly et al., 2019). Employees in organizations will establish many face-to-  
face relationships and social networks that increase the opportunities for those connections.  
Employees will then be more likely to be willing to share skills and thoughts with those with  
whom they have a special relationship (Chow & Chan, 2008). While creating and sharing  
knowledge in an organization is correlated with the social network structure, the building of a  
social network is the process of the knowledge creation and sharing process (Borgatti & Cross,  
2003). Because of the close relationships and network structure of the structural social capital,  
actors can more easily communicate with one another, thus increasing the flow of knowledge  
throughout the entire network (Reagans & McEvily, 2003). In particular, strong social networks  
with a high level of intensity, in which participants have frequent and close interactions, will  
help promote the spread of tacit knowledge (Ganguly et al., 2019).  
As a result, social interactions are crucial to the successful tacit knowledge-sharing  
process (Nonaka, 1994). In the course of the conversion and creation of knowledge in  
organizations, information is disseminated through “socialization”, which necessitates numerous  
social interactions between employees (Nonaka, 1994). However, compared to explicit  
knowledge, which is mostly transferred or shared through “combination,” which depends more  
on transactional interactions, social interactions have very little to do with it (Hau et al., 2013).  
Based on these arguments, it is reasonable to formulate the hypotheses as below.  
H4: Structural social capital is positively related to explicit knowledge sharing  
H5: Structural social capital is positively related to tacit knowledge sharing  
The relational social capital represented by trust and credibility is essential for a thick  
social network structure that promotes knowledge acquisition and assimilation (Ganguly et al.,  
2019). Trust among organizational members is a factor that improves interactive relationships  
and promotes successful knowledge sharing (Chow & Chan, 2008). Trusting others and allowing  
others to trust are essential for knowledge-sharing initiatives. If the organization members have  
trusted relationships, they are willing to allow colleagues to access their resources. Trust also  
increases the quality of knowledge sharing (Zaqout & Abbas, 2012). Inkpen and Tsang (2005)  
78  
Ha M. Tri, Doan B. Son. HCMCOUJS-Social Sciences, 11(1), 74-88  
assert that trust is essential to the coherence of relationships between parties. It acts as a check on  
opportunistic behavior and provides the basis for free knowledge exchange. In addition,  
interpersonal trust will promote tacit knowledge sharing (Foos, Schum, & Rothenberg, 2006).  
By establishing a common identity that facilitates the free exchange of knowledge and  
reduces the cost of learning, relational embeddedness eliminates barriers and promotes learning  
(Dyer & Nobeoka, 2000). Trust contributes to knowledge sharing by instilling a sense of security  
that the knowledge will not be used for purposes other than those for which it was intended.  
Operating systems that are common allows for the implementation of a shared communication  
protocol, which promotes the flow of information. To aid in clarifying and controlling  
information, relational nexus performs three key roles in knowledge sharing: clarification,  
control, and motivation (Dhanaraj, Lyles, Steensma, & Tihanyi, 2004). Trust can be  
conceptualized in two dimensions: benevolent trust and competence trust, according to Levin  
and Cross (2004). The empirical study conducted on this topic claims that perceived  
competency-based trust helps facilitate tacit knowledge sharing. In contrast, benevolence-based  
trust can facilitate both explicit knowledge sharing and tacit knowledge sharing. Their results  
suggest that relational social capital is crucial to forming dense social networks to act as a  
productive precursor of knowledge acquisition and assimilation (Ganguly et al., 2019).  
Therefore, it is appropriate to formulate hypotheses as follows.  
H6: Relational social capital is positively related to explicit knowledge sharing  
H7: Relational social capital is positively related to tacit knowledge sharing  
Cognitive social capital includes the goals, vision, and values shared by members of the  
organization. When trying to discern knowledge to be gathered and evaluated, participants’  
shared goals, language, and understanding are influential (Kogut & Zander, 1996). Similarly,  
Inkpen and Tsang (2005) assert that a common vision and a set of mutually agreed upon goals  
serve as a glue that motivates actors across an intra-corporate network to embrace and  
successfully integrate newly acquired knowledge. Social capital is comprised of various  
elements, all of which work together to shape how people behave. One of these elements is  
culture, which is defined as a shared set of values, beliefs, and norms. Together, these various  
elements mold how people behave cognitively (Wasko & Faraj, 2005). Individuals exchanging  
tacit knowledge through exchange mechanisms related to socialization need a common  
understanding and experience, and a mode of knowledge transfer involves shared experiences  
and thinking processes (Nonaka, 1994).  
Groups must have a common goal to foster mutual understanding and exchange of ideas.  
It’s thus possible to consider goals shared by two or more people to be the powerful force that  
holds them together and encourages them to share their knowledge. A goal shared by all  
members of an organisation can be obtained through cooperation and knowledge sharing (Chow  
& Chan, 2008). Therefore, it is relevant to formulate hypotheses as follows.  
H8: Cognitive social capital is significantly associated with explicit knowledge sharing  
H9: Cognitive social capital is significantly associated with tacit knowledge sharing  
2.3. Explicit knowledge sharing and tacit knowledge sharing  
Explicit knowledge is objective knowledge; in other words, it is written down and can be  
delivered to others, as well as made explicit using official avenues (Alavi & Leidner, 2001).  
Explicit knowledge is widely available, and it can be found in several different formats,  
including files, library collections, and databases (Nonaka & Takeuchi, 1995). However, it is  
difficult to precisely identify and quantify the extent of tacit knowledge, which is thought to be  
Ha M. Tri, Doan B. Son. HCMCOUJS-Social Sciences, 11(1), 74-88  
79  
derived from experience and primarily in the minds of individuals (Hlupic, Pouloudi, & Rzevski,  
2002). It has also been described as casual, free-flowing, private, and mysterious, and  
compelling. The issue here is that tacit knowledge is nearly impossible to represent in words  
accurately, and this makes it extremely difficult to put it in databases (Zaqout & Abbas, 2012).  
Organizational knowledge creation entails creating new content or updating existing  
content in the organization’s tacit knowledge and explicit knowledge (Pentland, 1995).  
Information is generated, shared, increased, enlarged, and substantiated in organizational settings  
by social and collaborative processes, as well as the individual’s cognitive processes, such as  
thinking, pondering, and consideration (Nonaka, 1994). Nonaka (1994) suggested that the  
process of generating and creating knowledge can be categorized into four processes:  
socialization, externalization, combination, and internalization, with the addition of transferring  
knowledge between tacit knowledge and explicit knowledge. Externalization is the process of  
taking existing tacit knowledge and turning it into new explicit knowledge (e.g., articulation of  
best practices or lessons learned) (Reychav & Weisberg, 2009). Because of this conversion,  
individuals are able to gain knowledge that, when expressed in terms of technical or academic  
data, is known as technical and educational documentation, such as manuals, documents, and  
patents (Nonaka, 1994).  
Tacit knowledge is integrative, challenging to express, and inferable by action. It’s fine-  
grained, and it gives the explicit knowledge more meaning and understanding. Tacit knowledge  
explains how the whole is better than the sum of its parts. Tacit knowledge, in essence, gives  
sense to many of an organization’s stated practices (Dhanaraj et al., 2004). Fundamentally, tacit  
knowledge refers to highly individualized information that is difficult to record or formalize  
(Nonaka, 1991). In addition, Hau et al. (2013) believe that sharing one’s explicit knowledge  
takes less work than sharing one’s tacit knowledge. A person who is eager to offer his or her tacit  
knowledge is undoubtedly willing to share his or her explicit knowledge (Hau et al., 2013). Tacit  
knowledge positively sharing promotes explicit knowledge sharing, according to Dhanaraj et al.  
(2004) and Chumg, Cooke, Fry, and Hung (2015). On the other hand, Reychav and Weisberg  
(2009) demonstrated that people who are eager to disclose their tacit knowledge are also likely to  
reveal their explicit knowledge. Thus, it is reasonable to propose a hypothesis as below.  
H10: Tacit knowledge sharing is positively associated with explicit knowledge sharing

3. Methodology  
3.1. Data collection and sampling  
This study adopts a survey design that uses a questionnaire to collect data. Respondents  
of this study were civil servants and public employees working in public departments in Tien  
Giang. Our study used a convenient sampling method to collect a sample size of 450 (Hair,  
Black, Babin, & Anderson, 2014; Kline, 2015). Before data collection, a pre-test of the  
questionnaire was performed with a small group of respondents (n = 10) to ensure the wording,  
content as well as special or technical terminologies that could be difficult to understand for  
respondents. The pre-test results show that cognitive and structural social capital dimensions  
may cause confusion. Consequently, our questionnaire provides a detailed explanation of these  
two terms. Data collection took place between March and April of 2021. With 450  
questionnaires distributed, 389 were returned, resulting in an 86.4 percent response rate.  
3.2. Measures  
Our study uses a five-point Likert scale, scoring from 1 denoting “strongly disagree” to 5  
denoting “strongly agree” to measure observed variables. Measurement scales were adapted  
from validated literature. Specifically, both structural social capital and relational social capital  
include four items adapted from Chow and Chan (2008) and Nahapiet and Ghoshal (1998).  
Cognitive social capital includes four items adapted from Chow and Chan (2008), and Miller,  
Besser, and Malshe (2007). Explicit knowledge sharing and tacit knowledge sharing, including  
six items and seven items, respectively, were adapted from Reychav and Weisberg (2009) and Z.  
Wang and Wang (2012).

3.3. Data analysis  
Data analysis employs a two-step approach provided by Anderson and Gerbing (1988).  
Data is analyzed using IBM AMOS 24 (Arbuckle, 2016). The first step is to establish a  
measurement model to confirm a Confirmatory Factor Analysis (CFA) procedure. Tests of  
reliability and validity are performed to determine how reliable and valid the measurement  
model is. The next step is to evaluate a structural model by performing a path analysis to confirm  
a set of hypotheses.

Analysis of model fit measures shows that CMIN/df = 2.379, p-value = 0.000, CFI =  
0.945, TLI = 0.936, SRMR = 0.0390 and RMSEA = 0.060. These results pass the cut-off values  
as suggested by Hu and Bentler (1999). Therefore, our data fit the model well. Table 3 indicates  
Ha M. Tri, Doan B. Son. HCMCOUJS-Social Sciences, 11(1), 74-88  
83  
that Composite Reliability (CR) of all six latent variables ranges from 0.834 (SSC) to 0.906  
(EKS) and Average Variance Extracted (AVE) ranges from 0.560 (SSC) to 0.660 (EKS). This  
implies that the model achieves convergent validity. In addition, none of the correlations  
between the construct exceed the square root of the AVE of each construct, implying that all  
latent variables or constructs receive adequate discriminant validity (Fornell & Larcker, 1981).

4.3. Structural model  
An analysis of the structural model is subsequently carried out to verify all proposed  
hypotheses. The subsequent step involves an estimation that uses maximum likelihood  
estimation to validate all the hypothesized relationships postulated from the research model  
(Byrne, 2016). Model fit measures reveal that CMIN/df = 2.379, p-value = 0.000, CFI = 0.945,  
TLI = 0.936, SRMR = 0.039, RMSEA = 0.060. It can be concluded that our data fit the model  
well, as seen in these results (Hu & Bentler, 1999). Hypothesis testing was performed and  
summarised in Table 4. Other than H5, all remaining hypotheses are statistically significant at  
different levels.

4.4. Discussion  
Our study proposes and tests a theoretical model that shapes the connection between  
social capital and knowledge sharing. Given the increasingly critical role of knowledge sharing  
as it can contributes to knowledge application, innovation, and eventually performance (Kim &  
Lee, 2005; Nonaka & Taikeuchi, 1995; S. Wang, Noe, & Wang, 2011), our study provides  
important evidence regarding how the three social capital dimensions influence both tacit  
knowledge sharing and explicit knowledge sharing. Theoretically, no attention has been paid to  
systematically examine how the three social capital dimensions affect knowledge sharing in the  
public sector. Therefore, our research is a pioneering work contributing significantly to social  
capital and knowledge-sharing literature. Furthermore, our findings substantially support our  
hypothesized model. Specifically, all hypothesized relationships were confirmed, except the  
relationship between structural social capital and tacit knowledge sharing.  
In the public sector context, we have asserted that all social capital dimensions are  
interrelated. Our findings corroborate previous research. Specifically, structural social capital has  
a favorable influence on relational social capital (Gabarro, 1978; Gulati, 1995; M. Granovetter,  
1985). Furthermore, Tsai and Ghosal (1998) showed that social interaction positively influences  
trustworthiness. At the same time, structural social capital also has a favorable influence on  
cognitive social capital. The social contacts of organization members have an impact on the  
establishment of a common vision (Krackhardt, 1990). Furthermore, research on organizational  
socialization (see, for example, Van Maanen & Schein, 1979) confirms the critical role of  
informal social interaction in promoting values learned about organizational norms, as is proven  
in the findings of Tsai and Ghosal (1998). Finally, the significant relationship between cognitive  
social capital and relational social capital was consistent with the work of Sitkin and Roth  
(1993), who contended that trusting relationships originate from value congruence.  
In a similar vein, our research results also show that relational social capital and cognitive  
social capital significantly influence both explicit knowledge sharing and tacit knowledge  
sharing. This result is completely in agreement with Hau et al. (2013), stating that common  
beliefs and goals have a favorable impact on sharing explicit knowledge and tacit knowledge. In  
addition, Zaqout and Abbas (2012) demonstrated the roles of trust in promoting explicit  
knowledge sharing and tacit knowledge sharing among workers, which is also in line with our  
findings regarding relational social capital. Several scholars argue that mutual trust between the  
knowledge-sharing partners is required for the effective transfer of tacit knowledge (Nonaka &  
Takeuchi, 1995). However, some say the absence of shared values, vision, and a shared goal can  
lead to conflict and impede trust, which acts as a barrier to the transfer of tacit knowledge.  
Additionally, while relational social capital is critical for effective tacit knowledge sharing and  
explicit knowledge sharing transfer, cognitive social capital also play a critical role in effective  
tacit knowledge sharing and explicit knowledge sharing transfer. This is consistent with the  
research conducted by Ganguly et al. (2019) and Zaqout and Abbas (2012).  
Interestingly, structural social capital only has a favorable impact on explicit knowledge  
sharing but has no significant relationship with tacit knowledge sharing. This result is in line  
with prior studies indicating no favorable effect between structural social capital and tacit  
knowledge sharing (Ganguly et al., 2019). Additionally, we found that tacit knowledge sharing is  
positively associated with explicit knowledge sharing. This finding corresponds with the studies  
mentioned above, including studies done by Cohen and Levinthal (1990), Chumg et al. (2015),  
Dhanaraj et al. (2004), and Hau et al. (2013). While Cohen and Levinthal (1990) posit that tacit  
knowledge is necessary to assist in comprehending explicit knowledge, Dhanaraj et al. (2004)  
Ha M. Tri, Doan B. Son. HCMCOUJS-Social Sciences, 11(1), 74-88  
85  
assert that tacit knowledge can provide the understanding behind explicit procedures in an  
organization; also, the tacit knowledge learned from workers will assist in learning new explicit  
routines. Similarly, Hau et al. (2013) found that employees’ tacit knowledge-sharing intentions  
are viewed as if they are sharing a more valuable resource, which can affect their explicit  
knowledge-sharing intentions. Finally, our findings align with Chumg et al. (2015), stating that it  
is critical to concentrate on externalizing the knowledge conversion process when creating new  
explicit knowledge from tacit knowledge in the virtual organization.  
5. Policy implications  
Our work provides several policy implications to create and encourage knowledge  
sharing by promoting the following dimensions of social capital. As for structural social capital,  
managers should encourage employees to actively participate in the network of relationships  
within departments as well as the network of relationships between departments to create and  
facilitate knowledge transfer.  
To promote relational social capital, managers should allocate more resources in building  
trust and enhancing cooperation among cadres and civil servants within and between departments.  
To develop and nurture trust, it is necessary to create a truly open and consistent working  
atmosphere. To promote collaboration at work, managers need to focus on and create favorable  
conditions for the working environment, facilities, equipment, and working facilities for  
employees. The more trust employees have the more knowledge they can share and benefit each  
other.  
To promote cognitive social capital, managers are responsible for establishing the  
organization’s vision and communicating it to all employees to encourage collaboration to  
enhance knowledge sharing. Public organizations need to build organizational culture, create  
consensus and cohesion among members of the organization so that everyone has a voice, and  
promotes ideas and initiatives in building visions and goals. This, in turn, inspires them to  
overcome difficulties and challenges to achieve effective work performance.  
Limitations and future research  
This work also has several limitations. First, this research has not analyzed and tested the  
role of control variables, for example, age, gender, educational level or experience. Future  
research should add these control variables in the analysis to better understand the possible  
differences in these variables that may be useful policy implications.  
Second, our study uses cross-sectional data, which only collects data at one single point  
of time to examine the link between social capital and knowledge sharing. Future research may  
use a longitudinal design to examine the possible changes over time to have better insights into  
more in-depth factors that may affect knowledge sharing in the public sector.  
Third, our study develops a theoretical model and only focuses on the public sector.  
Future research may expand the context to include other sectors, such as the business sector, to  
provide a complete view of social capital and knowledge sharing.
