不同地区的政务微博在活跃度、参与性和影响力等方面存在很大差异，为什么会如此不同？本文从政务微博的供给与需求两个方面提出了影响政务微博绩效的关键因素，并基于中国地级市的多源数据进行实证分析。结果显示，政务微博的绩效主要受供给侧的因素影响，如政府规模、财政健康状况和城市级别；相对来说，需求侧的变量对政务微博绩效的影响较弱，仅有移动互联网使用率同其存在正相关关系。本文探讨了这些研究发现的理论启示和政策意涵，并讨论了未来的研究方向。
The performance of government microblogs varies substantially across regions，and it is intriguing to explain what drives the difference.In this paper we identify a group of variables that may affect government microblog from the supply-demand perspective.We use multisource data of Chinese prefecture-level cities to empirically test the hypotheses.The results reveal that government microblog is primarily driven by supply-side factors，while the effects of demand-side variables are largely limited.We find that government size，fiscal health，administrative rank，and internet penetration rate are positively related to government microblog performance.We discuss the theoretical contributions and policy implications of the results，and conclude with avenues for future research.
