The dramatic rise of China’s digital leaders has put the squeeze on Western internet giants. Western players must learn quickly if they are to get back in the game in the world’s fastest growing digital market.

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.

So why have so few of the leading Western players succeeded in holding a winning share in China’s digital market? They know well the winner-takes-all stakes in digital business, and they have successfully dominated international markets in the past — after rolling out their digital products, platforms, and business models in other countries, without significant resistance.
