The success of Meituan is not by chance, but because of its efforts on both online and offline. So, it is important to do empirical research. However, there are little empirical research about online and offline can be found. Therefore, it is important and necessary, also innovative to carry out this research.

Chapter Two Literature Review

2.1 Background Reference
2.1.1 What is O2O
  O2O means Online to Offline, Online Mall releases information about products and services on discount to attract customers, if customers want to buy, they have to pay online, then they can get certain consumption password, by which they can achieve the products or enjoy the services they order online. With the development of Internet and Web, O2O can be seen as a new e-commerce model (Lu, and Li, 2013 p. 98-101). Here, there are three parties joining in: sellers, consumers and a third party. Meituan acts as a third party to save the money until sellers input the password getting from customers into the computer, after which, the money will be saved into the account of sellers, they can draw out money after a fixed period signed in the contract with Meituan.
2.1.2 What is Group buying (GB)
  Marketing pursues win-win results, which are firms gain profits and customers achieve certain products or enjoy certain services at a desired price. As science and technology develop, people are used to online shopping, and then come “tuango” in China, which translates as team buying. “Several people---sometimes friends, but possibly strangers connected over the internet-agreed to approach a vendor of a specific product in order to collectively bargain (haggle) with the proprietor as a group in order to get discounts (Zhang, 2012).” As time goes by, a specific website appears to act as a intermediary by which citizens can buy things on discount. The GB website will contact with sellers and let them show their products and services to attract customers’ attention, and if customers need it, they need to pay online to the GB website, after deal, the money will be paid to sellers by the website. In China, Many people, especially students are used to buy things on GB websites, such as Meituan, Dazhong dianping and Nuomi. These GB websites will update their data in time to give customers more choices and discounts.
2.1.3 Meituan, the first gainer
  GB website started from the USA, where the founder of Meituan Wang Xing being enlightened. As the first GB website in China, Meituan is the first gainer as well. By 2014, Meituan almost take up 60% of the market, as it develops better an better, many other GB websites close their companies forever. How can it survive from nearly 3000 companies of the same trade? O2O is the most common marketing strategy which GB companies use, so its success cannot depart from its efforts on it. 美团O2O营销模式和策略分析(2):http://www.youerw.com/yingyu/lunwen_20656.html
