The Eyes of the LORD are Everywhere: Tech-Enhanced Policing, Deterrence of Concealed Crimes, and the Decline of Missing Children
摘 要
Can technology deter concealed crimes—offenses with no direct victim to report them and whose detection relies entirely on proactive law enforcement? This paper addresses this question by exploiting the staggered rollout of China's Tech-Enhanced Policing reform. Without expanding police manpower or increasing working hours, the reform raised the probability of detection, tracing, and accountability through information system upgrades. Using city-level data on missing children across 337 Chinese cities from 2000 to 2012, we find that policing informatization reduces reported cases by 22.3 percent. The decline is driven by abandonment cases (26.3 percent)—non-professional, intra-family decisions—rather than organized trafficking (15.7 percent). Mechanism analysis reveals a 23 percent rise in cases solved per officer, with no systematic change in police force size or working hours. Our contribution is to provide the first evidence that technology-induced increases in the perceived probability of detection can generate significant ex ante deterrence against concealed crimes.

Innovation Under an Ivory Tower: Evidence from National University Science and Technology Park in China
摘 要
High-tech clusters play a pivotal role in advancing innovation, with universities frequently acting as core knowledge sources. This study investigates the innovation effects of China’s National University Science and Technology Parks (NUSTPs) policy—a large-scale place-based initiative that integrates universities and science parks to stimulate innovation. By combining firm-level data and patent data from multiple sources, we find that firms located within a 200-meter radius of NUSTPs exhibit a significant improvement in innovation performance. We identify two underlying mechanisms. The first is technological: NUSTPs drive innovation mainly through knowledge spillovers enabled by university researchers’ participation, university–firm collaboration, and knowledge transformation. The second is institutional: the inclusive institutional environment, supported by universities’ connections with local governments, reduces regulatory costs for firms operating in NUSTPs. Furthermore, grounded in the policy learning framework, our findings suggest that the future development of NUSTPs should strategically prioritize universities with strongest or lowest research and technology transfer capacities.
