China and the US have become the twin engines of global internet development, and the Chinese engine is apparently¹ younger and more vibrant² than its US counterpart, according to the findings of a white paper on China's internet economy released recently.

根据于日前发布的中国互联网经济白皮书的发现，中国和美国已成为全球互联网发展的双引擎，中国这个引擎明显比美国更年轻、更有活力。

The average age of Chinese netizens is 28, while the average age of US internet users is 42, according to the white paper jointly³ published by the Boston Consulting Group and the research arms of three Chinese internet giants - Alibaba, Baidu and Didi Chuxing.

这份由波士顿咨询公司与三家中国互联网巨头阿里巴巴、百度和滴滴出行的研究院联合发布的白皮书称，中国网民的平均年龄为28岁，而美国网民的平均年龄是42岁。

Besides the age advantage, others enjoyed by China over the US include high growth in users and online consumption, much faster penetration⁴ of various emerging applications, notably⁵ mobile payments, and greater vitality⁶ in internet economy that significantly shortens the time required for local businesses to become unicorns⁷, the report said.

该白皮书透露，除了年龄优势，与美国相比，中国的其他优势包括：用户和在线消费的高速增长，诸多新兴应用、尤其是移动支付的渗透速度更快，互联网经济的活跃度更高，这大大缩短了本地企业成为独角兽所需的时间。

The white paper, the first of its kind, is likely to be issued every year just like the much-anticipated annual Internet trends report by US venture capitalist Mary Meeker⁸, Gao Hongbin, head of AliResearch, said at the white paper release event.

阿里研究院院长高红冰在该白皮书的发布会议上称，这是第一个该类型的白皮书，它很可能会像美国风险投资家玛丽·米克尔的年度互联网趋势报告一样，每年都会发布。

The white paper highlighted four key elements to success in China's internet sector⁹ - local customization, rapid response to market needs, online-offline integration¹⁰, and the construction of a viable¹¹ ecosystem¹².

这份白皮书强调了在中国互联网行业取得成功的四个关键因素：本地化定制、快速响应市场需求、线上线下结合以及建设可行的生态系统。
