Innovation in Malmö after the Öresund Bridge
研究厄勒海峡大桥对瑞典马尔默地区发明活动的影响，发现大桥建成后该地区人均专利数显著增加，主要机制是吸引了高素质工人。
Abstract We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference‐in‐difference estimation on individual‐level data, our findings suggest that the Öresund Bridge led to a significant increase in the number of patents per individual in the Malmö region as compared with the two other major regions in Sweden, Gothenburg, and Stockholm. We show that a key mechanism is the attraction of highly qualified workers to the Malmö region following the construction of the bridge.
