Urban bikeshare systems have become increasingly popular in the U.S. in recent years. In this paper, I examine the effects of bikeshare systems on patterns of commuting to and from work in U.S. cities. To study this, I link cities across 2008 through 2016 American Community Survey (ACS) data and estimate the effects of bikeshare systems using both individual‐level ACS records and city panel data. Event‐study estimates suggest that bikeshare systems lead to a rise in bicycle commuting to and from work, and the effects of bikeshare systems are statistically and economically significant. I also find evidence of modal shifts after the introduction of bikeshare systems: While bicycle commuting rates increase, there is a decline in automobile commuting to and from work.

自由之轮，自由意志！共享单车系统对美国城市通勤模式的影响

近年来，城市共享单车系统在美国越来越受欢迎。在本文中，我研究了共享单车系统对美国城市上下班通勤模式的影响。为了研究这一点，我将 2008 年至 2016 年美国社区调查 (ACS) 数据中的城市联系起来，并使用个人层面的 ACS 记录和城市面板数据估计了共享单车系统的影响。事件研究估计表明，共享单车系统导致自行车上下班的增加，并且共享单车系统的影响在统计上和经济上都是显着的。我还发现了共享单车系统引入后模式转变的证据：虽然自行车通勤率增加，但上下班的汽车通勤率下降。
