Meituan, Dianping merger set to create an O2O giant

Liu Xuwei, an analyst at Beijing-based Internet consultancy Analysys International, said it remains to be seen how the former competitors can thrive after the merger.

"Meituan and Dianping accounted for more than 80 percent of China's group-buying market. Their businesses are highly overlapping and competing interests exist among their own partners."

For instance, selling movie tickets online is part of Meituan's key business, but Dianping is currently working closely with other ticketing service websites such as mtime.com.

"In the short term, the merger will help the two companies save costs, like reducing discounts to consumers. But it will be a long-term challenge for the two companies to prosper along with each other," Liu said.

What further complicates the deal is that Alibaba, an investor in Meituan, is marching into the market with its own brand of on-demand local services.

The e-commerce giant invested 6 billion yuan to set up Koubei.com in June.

"It is also unclear how Alibaba's Koubei will interact with the newly merged company in the future," Liu said.
