Ride-Sharing and the Geography of Consumption Industries
利用Uber在不同城市分阶段进入及其精确地理边界，研究发现网约车服务显著促进了城市消费产业的增长，原因是降低了出行经济成本、提高了消费者流动性。
Abstract Cities are centres of the consumption industries—establishments offering nightlife, food, recreation and retail. However, the city’s associated consumer value is inseparable from its geography because residents must travel to consume. By exploiting both the staggered entry across cities and the precise geographic boundary of Uber services for credible identification, we show that the introduction of ride-share technology into a city caused large and significant growth in the consumption industries. We provide evidence that the results are driven by an increase in consumer mobility, due to Uber causing a reduction in the economic cost of travel.
