中文摘要：

政务微博的运营绩效是衡量政务信息服务质量的重要评价指标。选取内容投入、结构投入和时间投入为输入指标，选取影响力为输出指标构建了多输入、多输出二级指标体系，并在此基础上利用数据包络分析方法的CCR模型测评了我国24个省级政府新浪官方微博的运营绩效，并根据分析结果为非DEA有效的政务微博选择了改进路径。研究结果显示：24个研究样本中仅有10个政务微博DEA有效。在输入指标中内容投入的贡献率明显高于结构投入，时间投入的贡献率最低。在输出指标中粉丝的互动率比粉丝数更能反映出微博的影响力。因此，政务微博的运营管理尤其要注重内容质量，要大力降低内容冗余，并提高外部信息资源利用率等来提高自身的影响力。

英文摘要：

Government microblogs＇ operation efficiency is a significant evaluation index during the process of government information service quality assessment. This paper chooses content, structure and time as input index and influence power as output index to form a multi-input and multi-output bi-level index system. CCR model of DEA is applied to evaluate 24 provincial government microblogs and promotion path selection is proposed for non-DEA efficient DMUs. The results show that, only 10 government microblogs are DEA efficient. From the aspect of input, the contribution rate of content input is higher than that of construction input, whereas the contribution rate of time input is lowest. From the aspect of output, the interaction rate of follower indicates the influence of government microblog better than the number of follower. Therefore, the operation management of government microblogs should concentrate on content quality and reduce input redundancy. The government can also increase the use of external information resources to enhance influence power.
