Title: Understanding Knowledge Sharing in Virtual Communities: An Integration of Social Capital and Social
1Understanding Knowledge Sharing in Virtual
Communities An Integration of Social Capital
and Social Cognitive Theories
2Introduction
- Rapid growth of virtual communities.
- Participate in virtual communities to seek
knowledge to resolve problems at work. - 42 of those involved in a virtual community say
it is related to their profession. - Many organizations have begun to support the
development and growth of CoPs to meet their
business needs and objectives. - For example, Caterpillar Inc. launched its
Knowledge Network in 1999
3Introduction
- Content (i.e., knowledge) of virtual communities
is the king . - The biggest challenge in fostering a virtual
community is the supply of knowledge. - Identifying the motivations underlying the
knowledge sharing behavior in virtual communities
- Two complementary social theories are applied
Social Cognitive Theory and Social Capital Theory
4Introduction
- Social Cognitive Theory (SCT) (Bandura, 1986 )
defines human behavior as a triadic, dynamic, and
reciprocal interaction of personal factors,
behavior, and the social network (system).
5Introduction
- Core of Social Cognitive Theory are self-efficacy
and outcome expectations. - Self-efficacy is a judgment of ones ability to
organize and execute given types of performances
. - Outcome expectation is a judgment of the likely
consequence such performances will produce .
6Introduction
- Virtual communities are online social networks
in which people with common interests, goals, or
practices interact to share information and
knowledge, and engage in social interactions. - It is the nature of social interactions and the
set of resources embedded within the network that
sustains virtual communities. - Studies on virtual communities address issues
related to both personal cognition and social
network . - Social Cognitive Theory is limited in addressing
what components are within a social network and
how they influence an individuals behavior
7Introduction
- Social Capital Theory the network of
relationships possessed by an individual or a
social network and the set of resources embedded
within it - strongly influences the extent to which
interpersonal knowledge sharing occurs (Nahapiet
and Ghoshal, 1998). - Nahapiet and Ghoshal define social capital with
three distinct dimensions - Structural the overall pattern of connections
between actors - Relational the kind of personal relationships
people have developed with each other through a
history of interactions - Cognitive those resources providing shared
representation, interpretations, and systems of
meaning among parties
8Research Model
In a voluntary setting, individuals who have no
confidence in their ability to share knowledge
would be unlikely to perform the behavior.
Therefore, the research model does not include
self-efficacy.
9Social Cognitive Theory and Knowledge Sharing
- People who come to a VC seek knowledge and
solving problem meet other people, to seek
support, friendship and a sense of belongingness. - According to the BUSINESS WEEK, 35 of those
involved in a virtual community say their
community is a social group. - Social Cognitive Theory a persons behavior is
partially shaped and controlled by the influences
of social network and the person's cognition. - Studies in the IS literature have demonstrated
the importance of self-efficacy and outcome
expectations for predicting and improving
computer training performance, computer usage,
and Internet behaviors.
10Social Cognitive Theory and Knowledge Sharing
- Researchers interested in understanding the
motivations prompting people to share knowledge
or participate in virtual communities have shown
the importance of social influences. - Strong community ties could provide important
environmental conditions for knowledge exchange
(Wellman and Wortley, 1990) - Trust a key element in fostering the level of
participation or knowledge sharing in virtual
communities (Ridings et al., 2002). - Bock et al. (2005) anticipated reciprocal
relationships ? attitude subjective norm ?
intention. - Some studies found that a sense of community
(Hars and Ou, 2002 ) and social identity
(Dholakia et al., 2004) can enhance the
likelihood of members contribution and
participation in a virtual community.

14Social Cognitive Theory and Knowledge Sharing
- Prior studies drawing upon Social Cognitive
Theory have ignored the importance of social
network influence - Studies in the virtual community literature have
paid less attention to the role of personal
cognition, such as outcome expectations. - Why do individuals spend their valuable time and
effort on sharing knowledge with members in
virtual communities? - According to Social Cognitive Theory, the
question should be addressed from the
perspectives of both personal cognition and
social network. - Consequently, Social Capital Theory is introduced
to supplement Social Cognitive Theory to address
our research question.
15Social Capital Theory and Knowledge Sharing
- Social capital the sum of the actual and
potential resources embedded within, available
through, and derived from the network of
relationships possessed by an individual or
social unit (Nahapiet and Ghoshal, 1998). - Putnam (1995) suggested that social capital
facilitates coordination and cooperation for
mutual benefit. - Tsai and Ghoshal (1998) empirically justified how
social capital facilitates resource exchange and
production innovation within the organization.
16Social Capital Theory and Knowledge Sharing
- Yli-Renko et al. (2001) examined the effects of
social capital on knowledge acquisition and
exploitation in young technology-based firms. - Virtual communities differ notably from
organizational settings since interaction among
community members is through online
communication. - Consequently, whether the impact of social
capital on resource exchange and knowledge
management activities found in the organizational
settings could be generalized to virtual
communities is still unclear.
17Social Capital Theory and Knowledge Sharing
Wasko and Faraj (2005 MISQ)
18Hypotheses H1
- Personal outcome expectations refer to the
knowledge contributors judgment of likely
consequences that his or her knowledge sharing
behavior will produce to him or herself. - According to Social Cognitive Theory, individuals
are more likely to engage in the behavior that
they expect to result in favorable consequences. - Several studies in IS research provided support
for this contention. - One study found that performance-related outcome
expectations had a significant effect on computer
use (Compeau and Higgins, 1995 ).
19Hypotheses H1
- The expectations of enriching knowledge, seeking
support, making friends, etc (Langerak et al.,
2004). - The expectations of being seen as skilled,
knowledgeable or respected (Butler et al., 2002).
- H 1a Members personal outcome expectations are
positively associated with their quantity of
knowledge sharing. - H 1b Members personal outcome expectations are
positively associated with the quality of
knowledge shared by them.
20Hypotheses H2
- Community-related outcome expectations refer to a
knowledge contributors judgment of likely
consequences that his or her knowledge sharing
behavior will produce to a virtual community. - Individuals share knowledge with the expectation
of helping the virtual community to accumulate
its knowledge, continue its operation, and grow
(Bock and Kim, 2002 Kolekofski and Heminger,
2003) - H 2a Members community-related outcome
expectations are positively associated with their
quantity of knowledge sharing. - H 2b Members community-related outcome
expectations are positively associated with the
quality of knowledge shared by them.
21Hypotheses H3
- Social interaction ties represent the strength of
the relationships, and the amount of time spent,
and communication frequency among members of
virtual communities. - Larson (1992) and Ring and Van de Ven (1994)
noted that the more social interactions
undertaken by exchange partners, the greater the
intensity, frequency, and breadth of information
exchanged. Knowledge is important in providing a
basis for action but is costly to obtain. - Nahapiet and Ghoshal (1998) argued that network
ties influence both access to parties for
combining and exchanging knowledge and
anticipation of value through such exchange .
22Hypotheses H3
- Recent studies have provided empirical support
for the influence of social interaction ties on - interunit resource exchange and combination (Tsai
and Ghoshal, 1998) - knowledge sharing among units that compete with
each other for market shares (Tsai, 2002), and - knowledge acquisition (Yli-Renko et al., 2001).
- H 3a Members social interaction ties are
positively associated with their quantity of
knowledge sharing. - H 3b Members social interaction ties are
positively associated with the quality of
knowledge shared by them.
23Hypotheses H4
- Trust has been viewed as a set of specific
beliefs dealing primarily with the integrity,
benevolence, and ability of another party in the
management literature. - This study focuses on integrity, which refers to
an individuals expectation that members in a
virtual community will follow a generally
accepted set of values, norms, and principles. - Nahapiet and Ghoshal (1988) suggested that when
trust exists between the parties, they are more
willing to engage in cooperative interaction.
24Hypotheses H4
- According to Blau (1964), trust creates and
maintains exchange relationships, which in turn
may lead to sharing knowledge of good quality. - H 4a Trust is positively associated with the
quantity of knowledge sharing. - H 4b Trust is positively associated with the
quality of knowledge shared by members.
25Hypotheses H5
- Norm of reciprocity refers to knowledge exchanges
that are mutual and perceived by the parties as
fair. - Social Exchange Theory (Thibaut and Kelly, 1959)
suggests that participants in virtual communities
expect mutual reciprocity that justifies their
expense in terms of time and effort spent sharing
their knowledge. - H 5a Norm of reciprocity is positively
associated with the quantity of knowledge
sharing. - H 5b Norm of reciprocity is positively
associated with the quality of knowledge shared
by members.
26Hypotheses H6
- Identification refers to an individuals sense of
belonging and positive feeling toward a virtual
community. - Identification is similar to emotional
identification proposed by Ellemers et al.
(1999). - Emotional identification fosters loyalty and
citizenship behaviors in the group setting
(Bergami and Bagozzi, 2000 ). - Emotional identification is useful in explaining
individuals willingness to maintain committed
relationships with virtual communities (Bagozzi
and Dholakia, 2002).
27Hypotheses H6
- Given that valuable knowledge is embedded in
individuals and people usually tend to hoard the
knowledge, one would not contribute his knowledge
unless another person is recognized as his
group-mate and the contribution is conducive to
his welfare. - H 6a Identification is positively associated
with the quantity of knowledge sharing. - H 6b Identification is positively associated
with the quality of knowledge shared by members.
28Hypotheses H7
- Shared language goes beyond the language itself
it also addresses the acronyms, subtleties, and
underlying assumptions that are the staples of
day-to-day interactions (Lesser, J. Storck ,
2001, p. 836). - Shared codes and language facilitate a common
understanding of collective goals and the proper
ways of acting in virtual communities (Tsai and
Ghoshal, 1998). - Nahapiet and Ghoshal (1998) stated that shared
language influences the conditions for the
combination and exchange of intellectual capitals
in several ways. - H 7a Shared language is positively associated
with the quantity of knowledge sharing. - H 7b Shared language is positively associated
with the quality of knowledge shared by members.
29Hypotheses H8
- Tsai and Ghoshal (1998) noted that a shared
vision embodies the collective goals and
aspirations of the members of an organization
(p. 467). - Cohen and Prusak (2001) argued that shared values
and goals bind the members of human networks and
communities, make cooperative action possible,
and finally benefit organizations, now to be
mentioned -- better knowledge sharing in terms of
quantity and quality. - H 8a Shared vision is positively associated with
the quantity of knowledge sharing. - H 8b Shared vision is positively associated with
the quality of knowledge shared by members.
30Research Methodology - Measurement Development
- Measurement items were adapted from the
literature wherever possible. - A pretest of the questionnaire 6 experts in the
IS area. - An online pilot study two professors, three Ph
D. students and 20 master students. - The dependent variables in this study are two
characteristics of knowledge sharing - the quantity of knowledge sharing
- the quality of knowledge shared (knowledge
quality)
31Research Methodology - Survey Administration
- The research model was tested with data from
members of one professional virtual community
called BlueShop. - A banner with a hyperlink connecting to our Web
survey was posted on the homepage of the BlueShop
from July 11 to August 18, 2005. - Thirty randomly selected respondents were offered
an incentive in the form of cash of 20. - The exclusion of 26 invalid questionnaires
resulted in a total of 310 complete and valid
ones for data.
32Research Methodology - Data analysis
- Data analysis utilized a two-step approach as
recommended by Anderson and Gerbing (1988) - Measurement model
- Structural model
- For a measurement model to have sufficiently good
model fit - The chi-square value normalized by degrees of
freedom (?2/df) should not exceed 3 - Non-Normed Fit Index (NNFI) should exceed 0.9
- Comparative Fit Index (CFI) should exceed 0.9
- For the current CFA model, ?2/df was 1.96
(?21194 df610), NNFI was 0.93, and CFI was
0.94, suggesting adequate model fit.
33Research Methodology - Data analysis
- Reliability was examined using the composite
reliability values. The composite reliabilities
of the constructs ranged between 0.82 and 0.93. - The convergent validity of the scales was
verified by using two criteria suggested by
Fornell and Larcker (1981) - (1) all indicator loadings should be significant
and exceed 0.7 - (2) average variance extracted (AVE) by each
construct should exceed the variance due to
measurement error for that construct (i.e., AVE
should exceed 0.50). - For the current CFA model, all loadings were
above the 0.7 threshold. AVE ranged from 0.61 to
1.00.
34Research Methodology - Data analysis
- The discriminant validity of the scales was
assessed using the guideline suggested by Fornell
and Larcker - the square root of the AVE from the construct
should be greater than the correlation shared
between the construct and other constructs in the
model.
35Research Methodology - Data analysis
- The structural model reflecting the assumed
linear, causal relationships among the constructs
was tested with the data collected from the
validated measures. - The model fit indices were within accepted
thresholds
36Research Methodology - Data analysis
37Discussion and Implications - Summary of Results
- The results indicate that community-related
outcome expectations play an important role
underlying knowledge sharing in terms of both
quantity and quality. - Personal outcome expectations have a negative but
insignificant effect on quantity of knowledge
sharing - It suggests that individuals contribute less
knowledge, even though they expect that knowledge
sharing will produce desirable consequences to
them. - One possible explanation for this finding might
be that when the impact of community-related
outcome expectation is taken into account,
knowledge contributors are more concerned about
the successful functioning, survival, and growth
of the virtual communities than the benefits that
will produce to themselves.
38Discussion and Implications - Summary of Results
- The study shows that social interaction ties,
reciprocity, and identification increased
individuals quantity of knowledge sharing but
not knowledge quality. - Tsai and Ghoshal (1998) found that social
interaction ties had a strong effect on trust in
the context of resource exchange and production
innovation within the organization. - According to Blau (1964), norm of reciprocity
builds trust, which in turn is centrally
important to social exchange relationships. - Accordingly, a possible explanation for the
findings may be that social interaction ties,
norm of reciprocity, and identification have
indirect effects on knowledge quality via trust.
39Discussion and Implications - Summary of Results
- Trust did not have a significant impact on
quantity of knowledge sharing. - One possible explanation may be that individuals
are willing to share their personal knowledge due
to close and frequent interaction among members,
fairness in exchanging knowledge, and strong
feelings toward the virtual community, without
necessarily trusting other members in the virtual
community. - Another possible explanation is that trust is not
crucial in less risky knowledge sharing
relationships. - Coleman (1990) argued that only in risky
situations do we need trust.
40Discussion and Implications - Summary of Results
- Shared language did not have a significant impact
on quantity of knowledge sharing - Shared vision had a negative and strong influence
on quantity of knowledge sharing. - One plausible explanation is that with shared
language and vision, contributors focus more on
quality rather than quantity of contributions. - This implies that they may not contribute just
for the sake of contribution but may be more
concerned about their quality of contribution. - An avenue for future research is to examine why a
negative relationship between shared vision and
quantity of knowledge sharing exists in the
virtual community settings.
41Discussion and Implications - Limitations
- Whether our findings could be generalized to all
types of professional virtual communities is
unclear. - The results may have been impacted by
self-selection bias. Our sample comprises only
active participants. - This study examined only one aspect of knowledge
exchangeknowledge sharing. - Fourth, the data presented are cross-sectional.
- The development of social capital leading to
knowledge sharing is an ongoing phenomenon. - This study focused on the paths from six facets
of social capital to knowledge sharing
42Discussion and Implications - Implications for
Theory
- Outcome expectations can contribute to knowledge
sharing to some extent, but it is the social
capital factors that lead to greater level of
knowledge sharing in terms of quantity or
quality. - Prior research suggests that a greater level of
knowledge sharing may lead to better development
of social interaction ties, mutual trust,
identification, and shared vision. - Future research should look at changes in social
capital and outcome expectations over time and
the relationships of those changes to knowledge
sharing. - Later studies should explore what factors
influence the facets of social capital in the
virtual community setting.
43Discussion and Implications - Implications for
Theory
- The results imply that individuals are less
concerned about the desirable consequences that
knowledge sharing will produce to them. - According to social exchange theory, however,
individuals will behave according to rational
self-interest. - Therefore, knowledge sharing will be stimulated
when its rewards exceed its cost (Kankanhalli et
al. 2005). - Thus, another direction for future research is to
examine whether reward systems are useful in
motivating an individual to share knowledge in
the virtual community and what form of reward or
incentive plays a significant role.
44Discussion and Implications - Implications for
Practice
- Social interaction ties were significant
predictor of individuals knowledge sharing in
terms of quantity. - Managers should develop strategies or mechanisms
that encourage the interaction and the strength
of the relationships among members. - Held face-to-face meetings or seminars.
- Invited top knowledge contributors and
professional instructors to share their knowledge
and experience with members of the community. - Personal message boards and blogs.
45Discussion and Implications - Implications for
Practice
- Managers of virtual communities can encourage
reciprocity by using extrinsic motivators such as
rewards for sharing knowledge. - For example, the BlueShop community provides a
mechanism that knowledge receivers can donate
value-added points (VP) to knowledge contributors
as a return of favors. - Earning VP by contributing knowledge can be
considered as an approach to forcing an
individual to reciprocate the benefits he or she
received from others. - The VP may represent knowledge contributors
status and reputation within the community and
can also be changed into monetary rewards from
the community.
46Discussion and Implications - Implications for
Practice
- Creating and maintaining a set of core and
experienced individuals plays an important role
in developing and sustaining a professional
virtual community. - Raising these core knowledge contributors
identification with the virtual community is one
of the approaches. - BlueShop provides a list of top knowledge
contributors for each week and month, enhancing
the contributors identification and also their
reputation. - BlueShop posts information about job
opportunities and outsourcing cases and help top
and well-recognized knowledge contributors get
those job opportunities and outsourcing cases.
47Discussion and Implications - Implications for
Practice
- The results suggest that trust plays an important
role in increasing the quality of knowledge
shared within virtual communities. - Research suggests that there are various types of
trust and the development of trust is
multi-staged in online communities (Ba, 2001) - Like the development of trust, the development of
knowledge sharing is also multi-staged. - Quantity of knowledge sharing may be the major
concern at the early stage of a virtual
communitys development - Knowledge quality may be the major concern when
the community becomes more mature.
48Discussion and Implications - Implications for
Practice
- Community-related outcome expectation plays an
important role in knowledge sharing. - The development and maintenance of virtual
communities depend not only on members knowledge
sharing but also managers strategies for running
the virtual communities. - For example, BlueShops strategy is to
- become members of famous alliance programs,
- receive online advertising cases, and
- win awards of excellent virtual communities to
enhance its reputation - meet members expectation of its sustenance and
growth.
49- The End!
