Tim Jordan’s book is organised around the surprisingly difficult question, ‘what is the digital economy?’ (p. 1). He approaches it through five case studies and two theory chapters before turning to policy recommendations inspired by his analysis. The case studies look at the search and advertise model, social media sites, disintermediation by companies such as Uber and Airbnb, fully free digital services and the digital gaming industry. Each is approached by analysing a small number of predominantly US cases such as Google and Facebook. Although Jordan also gives space to other cases such as Baidu’s search service, only WeChat is recognised as genuinely distinctive by comparison with the US cases.

书评：蒂姆乔丹，数字经济。

蒂姆·乔丹 (Tim Jordan) 的书围绕着“什么是数字经济？”这个令人惊讶的难题展开了讨论。（第 1 页）。在转向受他分析启发的政策建议之前，他通过五个案例研究和两个理论章节来处理它。案例研究着眼于搜索和广告模式、社交媒体网站、Uber 和 Airbnb 等公司的去中介化、完全免费的数字服务和数字游戏行业。通过分析少数主要是美国的案例（例如 Google 和 Facebook）来处理每个案例。虽然乔丹也给百度搜索等其他案例留出了空间，但与美国案例相比，只有微信才是真正与众不同的。
