摘　　要：随着核心参与者在网络问答社区知识共享中的作用愈发凸显,探究其知识共享障碍机制对于提高群体学习质量具有重要价值。研究首先通过扎根理论构建核心参与者知识共享行为意愿障碍因素模型;其次,利用系统动力学建立障碍机制模型,仿真探究核心参与者知识共享行为数量的演化规律及关键障碍因素对知识共享行为数量产生非线性影响的传导逻辑。研究发现知识共享主体障碍、客体障碍等4个障碍因素是核心参与者知识共享行为意愿的主要障碍因素,各因素间存在相互作用。仿真结果表明:核心参与者知识共享行为意愿和数量增速逐渐放缓;调节参数灵敏度后,各障碍因素均会导致核心参与者知识共享行为数量下降。其中,知识共享氛围障碍、核心参与者特征障碍等5个关键障碍因素对核心参与者知识共享行为数量阻碍作用明显,研究据此提出着重优化关键障碍因素所在反馈回路的建议。As the core participants in knowledge sharing within online Q&A communities become increasingly prominent,exploring the barrier mechanism of their knowledge sharing is crucial for enhancing the quality of group learning.The study firstly constructs a model of barrier factors to the willingness of knowledge sharing behaviors of core participants through grounded theory.Secondly,the study uses system dynamics to build a model of the barrier mechanism,and simulates to explore the evolutionary patterns of the quantity of knowledge sharing behaviors among core participants and the transmission logic of the non-linear influence of the key barrier factors on the quantity of knowledge sharing behaviours.It is found that four barrier factors,such as subject barrier and object barrier,are the main barriers to the willingness of knowledge sharing behaviors of core participants,with interactions among them.The simulation results show that the growth rate of willingness and quantity of knowledge sharing behaviors is gradually slowing down.After adjusting the sensitivity of parameters,each barrier factor causes the quantity of knowledge sharing behaviors of core participants to decline.Among them,five key barriers,such as knowledge sharing atmosphere barrier and core participant characteristics barrier,have a significant effect on the quantity of knowledge sharing behaviors of core participants.Based on this,suggestions are proposed to focus on optimizing the feedback loop where the key barrier factors are located.
