Disruptive Change in the Taxi Business: The Case of Uber
研究了优步等网约车服务相比传统出租车的效率优势，发现优步司机载客时间和里程占比显著更高，并探讨了原因。
In most cities, the taxi industry is highly regulated and has restricted entry. Ride sharing services, such as Uber and Lyft, which use mobile internet technology to connect passengers and drivers, have begun to compete with traditional taxis. This paper examines the efficiency of ride sharing services vis-a-vis taxis. In most cities with data available, UberX drivers spend a significantly higher fraction of their time, and drive a substantially higher share of miles, with a passenger in their car than do taxi drivers. Reasons for this efficiency advantage are explored.
