摘要

这项研究利用2014年至2019年中国的新数据，估计了大规模安装监控摄像头对犯罪的因果影响。利用现有的本地摄像头制造商作为摄像头部署强度的工具，我们发现拥有更密集监控网络的城市犯罪率明显下降。这种减少在公开可见的犯罪中更为明显。加强监控与对政府的更高满意度和更大的安全感有关，这反过来又导致工作时间更长。一个粗略的计算表明，预防犯罪大约需要花费6373美元，这是非常划算的。

Keeping an eye on the villain: Assessing the impact of surveillance cameras on crime

This study estimates the causal impact of the massive installation of surveillance cameras on crime, using novel data from China between 2014 and 2019. Leveraging the preexisting presence of local camera manufacturers as an instrument for camera deployment intensity, we find that cities with denser surveillance networks experienced significantly steeper declines in crime. The reduction is more pronounced for publicly visible crimes. Enhanced surveillance is linked to higher satisfaction with the government and a greater sense of security, which in turn leads to longer working hours. A back-of-envelope calculation shows that preventing a crime costs approximately $6,373, which is highly cost-effective.
