Social Exchange and Knowledge Sharing among Knowledge Workers: The Moderating Role of Perceived Job Security
研究基于感知组织支持理论和员工-组织关系理论，调查了255名中国IT行业员工，发现感知组织支持与知识共享正相关，但仅当员工感知到较高的工作安全感时才成立。
Drawing on perceived organizational support (POS) theory and employee-organizational relationship theories, this research investigated the association between POS and knowledge sharing as well as the potential moderating effects of perceived job security. Study participants were 255 information technology professionals and their supervisors working in the information technology industry in China. Findings showed that POS was positively related to knowledge sharing, and, as expected, perceived job security moderated the association. More specifically, the positive association between POS and employee knowledge sharing held only for employees who perceived higher job security from their organization. In contrast, POS was not significantly associated with knowledge sharing when employees perceived their job security to be relatively low. This latter result is consistent with contentions from employee-organizational relationships theories that limited investment by employers is likely to lead to lower contributions from employees. The findings are also congruent with arguments from social exchange theory that meaningful reciprocity is built on a history of open-ended exchanges whose development may be inconsistent with a shorter-term employment horizon.
