Influence of knowledge-oriented leadership and knowledge sharing on radical and incremental innovation: the moderating role of market turbulence

Purpose This study aims to analyze and clarify the influence of knowledge-oriented leadership (KOL) on radical and incremental innovation via the mediating role of knowledge sharing (KS). This study also explores the relationship between KS and two aspects of innovation capability by examining the moderating role of market turbulence. Design/methodology/approach The research model was tested using a structural equation modeling design based on survey data collected from 335 participants in 132 manufacturing and service firms in Vietnam. Findings The findings revealed that KOL serves as a key precursor to foster radical and incremental innovation directly or indirectly through KS processes. In addition, it highlights the moderating role of market turbulence in strengthening the impact of KS activities on two forms of innovation capability. Research limitations/implications By highlighting the important role KOL practice for stimulating KS behaviors, this paper provides a valuable understanding and novel approach for firms to improve radical and incremental. The research findings support the idea that market turbulence significantly contributes to increasing the effects of KS on innovation capability. Originality/value This study contributes to bridging research gaps in the the literature and advances the insights of how KOL directly and indirectly fosters innovation capability via the mediating role of KS processes under the market turbulence.
