基于知识贡献的社交问答平台个人创新行为研究

社交问答平台因满足用户对知识精准化与细分化需求，兼具社交功能日益受到人们的青睐，但仍存在活跃用户少，知识贡献积极性不高从而难以激发知识创新等问题，因此研究社交问答平台个人创新行为影响因素，对改善平台服务有重要意义。以社会资本理论和自我决定理论为理论基础，本研究从知识贡献角度建立了社交问答平台个人创新行为的结构方程模型，通过问卷调查，运用偏最小二乘法对研究模型和假设进行验证。研究结果显示，乐于助人、知识自我效能和互动强度是影响社交问答平台知识贡献的重要因素，进而影响用户个人创新行为。根据实证结果提出增强社交问答平台用户知识贡献意愿的相关对策和建议。

The results showed that the enjoyment in helping others,the knowledge self-efficacy and the intensity of interaction is an important factor affecting the knowledge sharing,then affecting the innovative behavior of users.
