the dual pressures of revenue increase and fierce competition, online meal ordering platforms have limited investment in restaurant qualification inspection and product quality audit. Therefore, illegal restaurants register on many platforms and receive recommendation through bid ranking. The online meal ordering industry needs to be further standardized. Seen from the market level, the online meal ordering market formed a three-way race in which ele.me, meituan.com and Baidu competed in 2016, with market concentration further improved.
