What is the development status of supermarkets? What about the business philosophy? urgent

The development status of supermarkets is: scale, branding, elimination of small and medium-sized supermarkets and rapid development of large supermarkets.

At present, reliable data show that the current consumption concept has changed from convenient consumption to economic rational consumption. Consumers will go to large and reputable supermarkets to buy goods, on the one hand, because the quality is guaranteed, on the other hand, because the variety is complete, and on the other hand, the service attitude is good. If large supermarkets do well, there will be free cars to pick up consumers' shopping according to a certain route.
