Title: 更大的城市，更多的通勤者，更多的犯罪？ 城市间通勤在城市犯罪规模中的作用

Abstract: Cities attract a daily influx of non-resident commuters, reflecting their roles within wider urban networks -- not as isolated places. However, it remains unclear how this interconnectivity shapes the way crime scales with population, given that larger cities tend to receive more commuters and experience more crime. In this work, we investigate how inter-city commuting relates to the population--crime relationship. We find that larger cities receive proportionately more commuters, which in turn is associated with higher levels of burglary, drug possession, robbery, shoplifting, and theft. For example, each 1% increase in inbound commuters corresponds to a 0.32% rise in theft and 0.20% rise in burglary, holding population size constant. We demonstrate that models incorporating both population size and commuter inflows explain variation in these offenses better than population-only models. Our findings underscore the importance of considering how cities are connected -- not just their population size -- in disentangling the population--crime relationship. Show Chinese abstract

Abstract: 城市吸引着每天大量的非本地通勤者，这反映了它们在更广泛的都市网络中的作用——而不是孤立的地方。 然而，鉴于较大的城市往往接收更多的通勤者并经历更多的犯罪，这种相互连接性如何影响犯罪与人口规模之间的关系仍然不清楚。 在这项工作中，我们研究了城市间的通勤如何与人口-犯罪关系相关。 我们发现，较大的城市会按比例接收更多的通勤者，而这与入室盗窃、毒品持有、抢劫、商店行窃和偷窃等犯罪率的上升有关。 例如，在保持人口规模不变的情况下，每增加1%的入境通勤者，会导致偷窃增加0.32%，入室盗窃增加0.20%。 我们证明，同时包含人口规模和通勤流入量的模型，比仅考虑人口的模型更能解释这些犯罪行为的变化。 我们的研究结果强调了在理清人口-犯罪关系时，考虑城市之间的连接性——而不仅仅是人口规模——的重要性。
