Purpose: The purpose of this study is to investigate the effects of intrinsic and extrinsic motivation on knowledge sharing and the moderating effects of individual demographics, organizational context and cultural context in that relationship.Design/methodology/approach: This study conducted a meta-analysis of 44 studies involving 14,023 participants to examine the direct and moderating effects of motivation on knowledge sharing.Findings: Results revealed that both extrinsic and intrinsic motivational factors were associated with higher levels of knowledge sharing, while the effect was stronger for intrinsic motivation. Moreover, results revealed that substantial variance was explained by moderating variables. Further investigation revealed that individual characteristics (age, gender), organizational context (organizational setting vs. open system, IT infrastructure) and cultural context (collectivism, uncertainty avoidance, performance orientation, power distance) moderated the motivation and knowledge sharing relationship.Research limitations/implications: As a meta-analysis, this study is confined to variables that have been frequently analyzed in prior research. Future research could further increase our understanding of different types of knowledge sharing and various boundary conditions.Practical implications: Organizations should provide customized incentive systems to specific target groups to align motivation and knowledge sharing. Multinational organizations may consider different motivation schemes across countries to better suit cultural differences.Originality/value: Despite a growing number of studies highlighting the important role of motivation in predicting knowledge sharing, the evidence is mixed. Based on a meta-analysis, this study identified true relationships and identified moderating effects that help explain prior mixed results.

Purpose: Innovation, including product, process, marketing, and organizational innovation within a firm, is considered as one of essential component for surviving and growing. These innovation activities create value and competitive advantages for successful organizations; therefore, understanding the organization’s overall innovation is the first and foremost to understand the role of innovation on firm performance. The objective of this research is to explore two parts: the impacts of innovation on the different aspect of innovation performance, then their effects to firm performance (production, market, and financial performance).Design/methodology/approach: This study uses primary data from questionnaire survey. The questionnaire involves 4 parts including general information, innovation activities; innovative performance, and firm performance. This research focuses on firms in supporting industries of mechanics, electronics, motorbike and automobile. These firms are in a list of companies (known as The Excellent Vietnamese Companies in Northern and Central Vietnam) established by JETRO and VCCI. There are 150 firms in this list. The questionnaire survey was administered to directors, CEO of those firms during April and May, 2014. Out of the 150 questionnaires sent out, 118 were valid, accounting for 78.7% of the true response rate. Analysis methodologies of reliability, factor analysis and regression are utilized in this paper.Findings: The result demonstrated there are positive effects of process, marketing, and organizational innovations on firm performance in supporting firms. More specifically, the higher the level of innovation activities is, the greater the innovative performance is, which means the larger level of Process, organization and marketing innovation activities are, the higher level of innovative performance are likely to be. Secondly, the higher level of Process, organization and marketing innovative performance, the better level of firm performances is likely to be. To sum up, in order to improve the innovative and firm performance, those firms in supporting industry should highly concentrate on process, marketing, and organizational innovation activities, rather than product innovation activities.Originality/value: Initially, this study applies successfully the model which supposing innovation is a process, then clarifying innovation definition through the impact of innovation activities on innovative performances. Secondly, this research confirmed the positive impact of innovative performances on firm performances. It provided one more empirical evidence of the relationship between innovation and firm performance. For practitioners, organizational innovation and process innovation are more important factors affecting innovative performance and firm performance than product and marketing innovation. Therefore, enterprises should focus and mobilize resources to create improvement in organizational structure and manufacturing processes.

Purpose: The theory of planned behavior (TPB) is the most frequently used model in knowledge sharing. However, the empirical results are inconclusive on whether TPB can provide reasonable prediction of knowledge sharing behavior (KSB). This study aims to examine TPB in knowledge sharing and identify potential moderators of relationships among constructs in TPB. Design/methodology/approach: This study conducted a systematic review and meta-analysis of 26 studies examining TPB in knowledge sharing. A meta-analytical structural equation model (MASEM) was used to test original and modified TPB models and examine potential moderators. Findings: The results show that attitude has the strongest relationship with intention, followed by perceived behavior control and then subjective norms. Intention shows the strongest association with KSB, followed by perceived behavior control. The moderator roles of culture, economic wealth and information technology support are found in the model. Originality/value: This study is the first attempt to provide a systematic review and MASEM in TPB in knowledge sharing.

This paper aims at investigating the relationship between knowledge sharing activities and innovation capability at both individual and organizational levels. By reviewing extensive literature, a conceptual framework is built with integrating three factors: knowledge sharing, individual innovation capability and firm innovation capability. This study applies structural equation modeling (SEM) to analyze the data collected from 392 employees working at major Vietnam’s telecommunication companies. Empirical results show that knowledge sharing including knowledge donating, knowledge collecting play an important role in improving individual innovation capability. There is no direct link between knowledge collecting and organizational innovation capability, while knowledge donating has direct positive impact on product and managerial innovation. Furthermore, the individual innovation capability acts as a mediating variable between knowledge sharing practices and firm innovation capability. Implications for academics and practitioners are provided in this study.

Based on previous findings, which found that the three facets of ability-based emotional intelligence (EI) have varying effects on job performance, this study investigates the relationship between emotional intelligence, cognitive intelligence (CI), and job performance. The use of a cascade model suggests a progressive pattern, starting from emotion perception, followed by emotional understanding and emotion regulation, with downstream effects on job performance. Considering the advantages and disadvantages of both measurements, we employed the performance-based ability measurement, the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT) and the self-reporting ability EI measurement, Wong Law Emotional Intelligence Scale (WLEIS). Our findings supported the cascade model, but in the case of WLEIS measures, both self-emotion appraisal and others’ emotion appraisal precede emotion regulation, leading to a positive effect on job performance. Moreover, CI moderated the relationship between EI and job performance, such that a decline in CI rendered the relationship more positive. The MSCEIT and WLEIS showed similar results, thus supporting the cascading model and moderating effects.

Purpose: Innovation is considered as a core element of sustainable competitive advantage in the rapidly changing environment. However, in Vietnam, researches on innovation are very rare, which are mostly general reports without underlying analyses of innovation in firms, especially determinants for innovation. Therefore, this paper focuses on analyzing critical successful factors for innovation in Vietnamese firms. Design/methodology/approach: This study used primary data through questionnaire survey from November 2015 to February 2016. Respondents were senior managers of firms located mostly at Hanoi (Northern), Hochiminh (Southern) and Danang city (Central). The questionnaire included multi-items designed to measure factors. Each item was measured by 5 point Likert scale: 1 (strongly disagree) to 5 (strongly agree). Questionnaires were administerd to 500 firms belonging to list of Vietnam Chamber of Commerce and Industry (VCCI) in these three cities with rate of 40% (Hochiminh city), 40% (Hanoi city) and Danang (20%). However, there were 360 returned questionnaires and valid to next analyses. Analysis methodologies of reliability, factor analysis and regression are utilized in this paper. Findings: We developed and tested a model of determinants for Innovation in Vietnamese firms. The major contribution of this study is testing six determinants for innovation in Vietnamese companies. The results showed that awareness of innovation, innovation strategy and policy, organization for innovation, HR for innovation and building capabilities have positive impact on innovation. Originality/value: This study makes a contribution for both academics and practitioners. For academics, this study provided one more empirical evidence of the determinants for innovation. Regarding practical implications, this study suggests that Vietnamese companies have to strengthen capabilities for employees through training, encourage generation of new ideas, rule breaking, and innovative behaviors by organizational members. Together, having high awareness of innovation, building rational innovation strategy and policy is essential factors that firms should possess and develop to enhance innovation performance. Although there is no confirmation for impact of finance on innovation level, firms should understand that increasing innovation investment can bring favorable condition to create innovation especially in SMEs.
