What is the difference between the traditional retail industry in China and the traditional retail industry in the United States?

The domestic retail industry does not systematically study the needs of customers, so as to screen, study, satisfy and give back to target customers; Many companies are in a state of confusion, but they are unwilling to spend money and time to do it, including large state-owned enterprises such as China Resources. So I cast a big net, and I didn't do it in detail. So I think this aspect is very different from foreign retail industry. In addition: At present, foreign-funded enterprises are doing a good job in category management in China, and some consulting companies are also doing a good job, such as Nielsen. Domestic enterprises still have to learn. The data capability behind the IT system, aside from financial and personnel management, is only a supply chain module in this IT system as a sample, so we won't talk about the monster level of Wal-Mart. The goods of most American enterprises come from China, Southeast Asia and the whole world.
