Enhancing the adoption of digital public services: Evidence from a large-scale field experiment
通过大规模现场实验，研究如何用助推手段（如信息提示和社会影响）促进慢速采纳者使用在线政府服务，发现最有效的干预使采纳率翻倍。
Governments increasingly digitalize the provision of their public services, but these efforts fail to generate expected social benefits if the services remain underutilized. We use a large-scale field experiment to provide causal evidence on how a concrete policy instrument, nudging, can be used to address such underutilization by a group of slow adopters. Our experiment is conducted in a real-world setting with actual citizens and makes use of informative and social influence nudges. We find that such behavioral interventions enhance the adoption of an online government service among the slow adopters. The effects are statistically highly significant and quantitatively large. The most effective experimental treatment doubles the adoption rate.
