In fact, the scope of protection in this respect is not clearly defined. Generally, each brand will be different. Generally, this range will be determined according to many factors, such as the economic development of this area, or the product characteristics of this brand, or the development direction of this brand, or the population density of this area. If these popular brands that join that kind of restaurant are located in some densely populated places, then many consumers will come to join the store. However, this franchised brand with many customers generally does not set up a wide range of regional protection in this regard. If this area is too wide, it is easy to miss some consumers, resulting in a waste of market resources. For the joining of restaurants, the regional protection policy will be about one to three kilometers in radius. In this way, we can calculate that the area of this area is about 3~30 square kilometers. Moreover, the locations opened by these franchisees are not all concentrated in places with many people, so if they are in places with few people in the city, then this area will be even larger.

If some luxury goods, training and other consumer groups are not many franchised brands, then their consumer groups will naturally be much less, so the regional protection scope of these franchisees will be wider, and it is impossible to be as dense as joining restaurants. Perhaps only a few cities are enough to carve up the market share of this city.
