Improving citizen compliance is a major goal of public administration, especially during crises. Although social media are widely used by government agencies across the globe, it is still unclear that whether the use of social media can help local governments improve citizen compliance especially during crises. Based on an original daily panel dataset of 189 cities in China during COVID-19, this study provides empirical evidence for the positive effect that crisis-related social media posts published by local government agencies has on citizen compliance. In addition, this effect is mediated by the topic of prevention measures in social media posts, and is stronger in cities with higher GDP per capita, better educated citizens and wider internet coverage. The findings imply that social media is an efficient and low-cost tool to assist local government agencies to achieve public administration objectives during crises, and its efficacy is largely dependent on regional socioeconomic status.
This paper investigates whether and how import competition affects firm innovation. Using China's World Trade Organization (WTO) accession as a quasi-natural experiment, we find that import competition reduces firm innovation, which is consistent with the Schumpeterian effect. We also find heterogeneous treatment effects across firm productivity and patent types in a way consistent with preference and knowledge spillover effects, but not with escape-competition and trapped-factor effects.
改革开放以来,我国重大政策宣介中常出现“借鉴发达国家经验”的提法。但这种宣介方式能否提升公众对该政策的支持度,仍是一个尚未被检验的问题。论文选取房产税政策为研究对象,利用网络调研实验方法,识别发达国家政策信息如何影响公众对国内相关政策的支持度。研究发现:(1)向公众提供发达国家的政策信息并不会显著影响他们对于房产税政策的支持程度;(2)对年轻人和低收入水平的受访者而言,提供发达国家的政策信息,显著降低了他们对于国内房产税政策的支持度;(3)提供发达国家政策信息显著降低了公众对于房产税适合中国国情的判断。研究结果启示决策者在我国未来如房产税、延迟退休、开放生育等重大政策的宣介过程中,须谨慎使用“借鉴发达国家经验”的提法,尤其须注意该提法对不同群体政策支持度的异质性影响。
