The explosive growth of the digital market in China, a country with more than 700 million internet users, constitutes a rich prize to companies that can exploit its opportunities. Five of the 10 largest public internet companies in the world — Tencent Holdings Ltd., Alibaba Group Holding Ltd., Baidu Inc., JD.com Inc. (aka Jingdong), and NetEase Inc. — have emerged from this $1 trillion market. And, by February 2018, Chinese companies accounted for 33% of the world’s unicorns (privately held startups valued at $1 billion or more), with almost three-quarters of them targeting digital or online markets.
