►Business： Chinese internet firms Clubbing together
The merger of Meituan and Dianping could herald a bigger consolidation.
GROUP buying—in which discounts are offered on goods and services once a certain number of consumers have signed up—may be falling out of fashion in many countries， with even America's pioneer， Groupon， slashing over 1，000 jobs last month， but it is still doing well in China.
According to Analysys International， a research firm， bargain hunters there rang up 77 billion yuan ($12.1 billion) in sales through group-buying websites in the first half of this year.
That is a rise of 168% on a year earlier.
Even more striking is news this week of a merger between the two biggest Chinese firms in the business， which may herald a broader consolidation in China's internet sector.
Groupon has flopped in China， just as many other Western internet firms have done.
This has left the field clear for local businesses.
On October 8th two Chinese companies which between them have about four-fifths of the local group-buying market said that they would combine.
Meituan， with about half of the market， will join forces with Dianping， which has about 30%.
The combined business will be worth perhaps $15 billion.
It will quash competition on one front of a costly proxy war now being fought by China's big three internet firms—Alibaba， Baidu and Tencent.
Alibaba has a stake in Meituan， while Tencent backs Dianping.
The merged entity would dwarf Nuomi， which has a mere 14% share of China's group-buying industry.
It is fully owned by Baidu， which said in June that it would invest $3.2 billion over the next three years in this sort of e-commerce business.
The deal marks an escalation in what seems to be an effort by Alibaba and Tencent to squeeze out Baidu and turn the Chinese internet's big three into a big two.
They have already joined up to try to create a dominant company in the online taxi-hailing business.
At first each had backed a different startup in this area， but when Baidu gave financial backing to Uber， an American taxi-app giant， to expand its presence in China， Alibaba and Tencent merged their proxies into a firm now called Didi Kuaidi.
