摘要翻译：
近日，法国参议院批准了一项法律，对一定规模以上的公司从数字服务中产生的收入征收3%的税。虽然关于这一行动的经济后果有很多政治辩论，但扭转这个问题实际上很有趣：我们考虑没有这种数字税的经济的长期影响。更一般地说，我们可以把数字服务看作是运输成本低或零的产品的特例。我们用基本的经济模型表明，一个没有运输成本的市场容易出现垄断，因为微小的、随机的质量差异会得到不成比例的回报。然后，我们提出了一种基于距离的税收，以抵消随机集中的趋势。与按物理（基数）距离扩展的税收不同，等级（序号）距离税在保持稳定经济的同时利用了数字化的好处。

英文摘要：
  Recently, the French Senate approved a law that imposes a 3% tax on revenue generated from digital services by companies above a certain size. While there is a lot of political debate about economic consequences of this action, it is actually interesting to reverse the question: We consider the long-term implications of an economy with no such digital tax. More generally, we can think of digital services as a special case of products with low or zero cost of transportation. With basic economic models we show that a market with no transportation costs is prone to monopolization as minuscule, random differences in quality are rewarded disproportionally. We then propose a distance-based tax to counter-balance the tendencies of random centralisation. Unlike a tax that scales with physical (cardinal) distance, a ranked (ordinal) distance tax leverages the benefits of digitalization while maintaining a stable economy.
