【目的/意义】对政务微博信息交流效率展开评价,指导政务微博运营管理与内容建设,并丰富社交网络环境下的信息交流理论研究。【方法/过程】以外宣、司法、团委等十大类型政务微博为研究对象,基于内容、关系、时间三个维度,选取提及行为“@”、话题标签“#”、互动数等指标,构建了政务微博信息交流效率评价的指标体系。采用DEA-VRS模型对政务微博的信息交流效率展开评价,通过冗余分析为不同类型的政务微博的信息交流效率改进提供建议。【结果/结论】政务微博信息交流效率处于中等水平,合理配置相关政务微博的投入规模可有效提高其信息交流效率水平。

英文摘要：

[Purpose/significance]The paper evaluates information exchange efficiency of government microblogs, it can be used to guide the operation, management and content construction of government microblogs, and it can also enrich the theory of information exchange in social networking environment. [Method/process] Taking ten government administration types such as publicity, justice and Youth League Committee as research objects, the paper selects indexes such as mention behavior ＂@＂, topic label ＂#＂ and interactive number and constructs the evaluation index system of information exchange efficiency of three dimensions including content, relation and time. The DEA-VRS model is used to evaluate the information exchange efficiency of government microblogs. The paper puts forward some suggestions on the improvement of information exchange efficiency of different government microblogs by means of redundancy analysis. [Result/conclusion] Microblogs government information exchange efficiency level is moderate, the reasonable allocation of investment scales of relevant government microblogs can effectively improve the level of information exchange efficiency.
