| 摘 要： | 基于样本数据的收集，发现学术社区知识共享主体具有身份的相对稳定性、交流内容的专业性、交流态度的严谨理性等共性，同时，人文管理类与理工类社区在话题来源、语言风格以及对知识权威的认同等方面存在差异。引入基尼系数对社区主体间知识共享不均衡程度进行分析，发现人文管理类社区主体间不均衡程度明显高于理工类社区；使用社会网络分析对学术社区知识共享主体构成进行分析，发现两类学术社区都存在中心势过低的现象，同时人文管理类社区更容易形成社区核心。

| Abstract: | Based on the collection of sample data, some common characteristics of knowledge sharing subjects in academic community are found, including the relative stability of identity, the professional quality of communication content and the strict and rational attitude. However, some differences between the communities of humanity-management and engineering-science are also found，such as the source of topics, the language style and the acceptance of knowledge authority. Gini coefficient is introduced to measure the level of imbalance in the community activities. The values show that there is much more imbalance in the humanity-management communities than in the engineering-science ones. The subject construction is analyzed by social network analysis and it is found that both the communities have the low network centralization and the community core is more easily formed in the humanity-management community. |
