城际客运如何塑造城市就业和专业化模式？为了阐明这个问题，我研究了中国的高速铁路（HSR），这是一个前所未有的大规模网络，从2003年到2014年，它连接了81个城市，列车运行速度超过200公里/小时。使用差异中的差异方法，我发现高铁连接增加了10%的城市范围内的客流量和7%的就业机会。为了解决内生铁路布局和同时伴随高铁连接的公共投资问题，我研究了纯粹由其他城市的高铁连接驱动的城市市场准入变化的影响。估计数表明，高速铁路引起的市场准入扩大增加了城市就业，弹性在2和2.5之间。有关部门就业的进一步证据表明，对非常规认知技能依赖程度较高的行业从高铁引发的其他城市市场准入中获益更多。(C)2016 Elsevier Inc.

How does intercity passenger transportation shape urban employment and specialization patterns? To shed light on this question I study China's High Speed Railway (HSR), an unprecedentedly large-scale network that connected 81 cities from 2003 to 2014 with trains running at speeds over 200 km/h. Using a difference-in-differences approach, I find that an HSR connection increases city-wide passenger flows by 10% and employment by 7%. To deal with the issues of endogenous railway placement and simultaneous public investments accompanying HSR connection, I examine the impact of a city's market access changes purely driven by the HSR connection of other cities. The estimates suggest that HSR-induced expansion in market access increases urban employment with an elasticity between 2 and 2.5. Further evidence on sectoral employment suggests that industries with a higher reliance on nonroutine cognitive skills benefit more from HSR-induced market access to other cities.
