The difference lies in the existence of the phenomenon of Meituan killing. First, the U.S. group to kill the familiar:With the development of the Internet era, people's lives have been very much away from the Internet. Buy things to buy online, eat to order takeout, buy food to the next day, travel will also be from the online group purchase of hotels, tickets, tickets and so on. The emergence of the network does bring great convenience to people's lives, people can enjoy preferential prices at the same time, improve efficiency, like the emergence of takeout, so that many office workers can go home without having to do it themselves, you can eat a hot meal. Whether it's takeout, grocery shopping or group buying, Meituan APP is involved, which makes Meituan an inseparable part of people's lives. With the increase in features, favorable prices and ease of use, Meituan has also made people's trust in Meituan grow. However, he has repeatedly failed consumers' trust. As early as two years ago, a consumer reflected on the network, Meituan there is "kill familiar" behavior. When he ordered takeout, he found that the delivery fee was based on whether the user was a member or not. However, what makes him even more angry is that at the same time, the same cell phone with a restaurant, members of the delivery fee is higher, members of the delivery fee is generally more than non-members of the 1 ~ 4 yuan, this point makes him very incomprehensible, the members are trusting the United States group for, but the United States group of this practice but the familiar customers as a lamb to slaughter. This matter in the network made a fuss, the United States group president Wang Xing also responded to the matter, he said it is not the United States group of killing familiar behavior, but because the positioning system cache, resulting in positioning deviation, so the delivery price is different, and said that a special technical team has been set up to solve this problem. But this statement is obviously not convincing, as long as the people who have ordered takeout know, Meituan takeout in the order only to determine the location of the final bill will be projected. Meituan this practice is very clear that there is "big data kill familiar" behavior. The attitude of not recognizing and not admitting fault also led to a few days later, the Meituan stock market fell more than 2.3%, the loss reached 40 billion. But this storm did not make the United States group back to the shore, not long after the United States group topped the risk of once again "big data to kill familiar", this time the United States group can still escape? Second, the United States group big data double standard: a media survey found that most consumers are platform to kill familiar, and the Consumer Association also found that the United States group platform to kill familiar complaints are also very much. This time the beauty group is not in the membership and non-membership of the identity of the hands, but in the user to use which cell phone on the hands. The survey found that the same dish at the same address at the same time, just a different cell phone, but can appear a variety of prices, the use of Apple machine users, than the use of Android users prices are 14% higher. In addition to takeout, Apple phones for Meituan membership are eight dollars higher than Android phones. There's also hotel booking, where prices vary from phone to phone. There is a blogger who did an experiment, he used three different cell phones to book the same hotel at the same time, but the price of the Apple phone appeared to be much higher than that of the Android phone, and even the price of different models of Apple appeared to be different, and the more expensive the price of the Apple was higher. Such a phenomenon as early as 2019, there is a consumer outbreak, there are rumors that the United States will use the Apple phone users marked as "quality users", in addition to the price is obviously expensive, they will also give Apple users to push more expensive goods. Third, the big data kill familiar behavior: Meituan kill familiar has been nailed, if Wang Xing does not make any changes, it is likely to be boycotted, or punished by the relevant departments. Because there is no other app can replace the position of the United States group, so the United States group long-term monopoly of the market so that they do whatever they want, they in order to gain benefits repeatedly kill familiar. Because of the monopoly, Meituan has been fined 3.4 billion dollars, if the country began to rectify the behavior of killing familiarization, Meituan should be fined more. Wang Xing should be vigilant, the same market monopoly, Alibaba today's state has been poor, perhaps the United States will step Ali's old way. In fact, in addition to the U.S. group, many APPs have the behavior of killing the familiar, like taxi with the drip, shoot video for promotion of jittery voice, microblogging, etc., will be differential pricing, mostly Apple users are being ripped off. They analyze the purchasing power of consumers, and put the way to make money on "familiar customers". The good thing is that the relevant state departments have officially implemented the control of differential treatment, differential treatment is illegal, consumers can reflect to the relevant departments to protect their rights and interests.
