大型展会对城市发展有显著的“弯道加速”作用,这是毋庸置疑的。比如2008年的北京奥运会,2010年的上海世博会,所在城市在申办、筹办、举办国际盛会的过程中,获得了跳跃式的前进。其实,不只是我们熟知的北京和上海,100多年前,美国的芝加哥就向世人验证了这个道理,而当时的一张手绘地图恰好记录下了这个历史事件。1892年,是哥伦布发现美洲大陆400周年,美国决定举办一次世界博览会作为庆祝。在与圣路易斯、纽约和华盛顿竞争举办资格的过程中,芝加哥无疑具有明显优势:芝加哥地区铁路里程数占全美 There is no doubt that large-scale exhibitions have a significant “cornering acceleration” effect on urban development. Such as the 2008 Beijing Olympic Games, the 2010 Shanghai World Expo, where the city in the bid to host, hold an international event in the process, has been leaps and bounds. Actually, not only are we well-known in Beijing and Shanghai, more than 100 years ago, Chicago in the United States proved this truth to the world. A hand-drawn map of the time just happened to record the historical event. In 1892, when Columbus discovered the 400th anniversary of the American continent, the United States decided to hold a world exposition as a celebration. Chicago undoubtedly has the obvious advantage in competing with St. Louis, New York and Washington for its eligibility: Chicago’s regional railways account for the entire United States
