底特律综合症

发自新加坡——上星期底特律市政府提交的破产申请堪称美国有史以来最庞大的一起破产事件。这座城市的人口在1950年时位居全美第五,约为180万人,而如今则锐减成不到70万。整座城市的工业基础也早已分崩离析。

但我们依然生活在一个最美好的城市时代。有史以来第一次有超过一半的全球人口居住在城市,而这次城市汇聚之处则创造了全世界超过80%的GDP。随着新兴市场国家的快速城市化,这一数字将继续攀升。那么,我们又能在底特律的困境中得到些什么教训呢?

在1990年代时,许多专家建议说科学技术将淘汰城市。他们相信当时尚处萌芽状态的互联网和移动通讯会使得人们不再需要住在拥挤而高生活成本的城市地区。但事实上在经历了数十年的人口流出之后,像纽约和伦敦这样的城市自1990年以来都出现了人口暴涨。

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
