Consumption level: above the county level (average level in Shandong Province)
If the per capita income refers to local people, it may exceed 1000, because some well-developed sectors have higher per capita income (for example, residents under Nanshan Group have higher income).
Regarding opening a shop, I think the catering industry has potential. Going to Longkou, I feel that there are still few restaurants suitable for mid-range consumption. If I have the ability, I can choose to open a chain restaurant. It's hard to say if you want to open a small shop. In fact, all the cities in China have the same balanced development, and all industries have potential, but all industries have great risks, so you need to make on-the-spot investigation and comparison.
A prosperous place, Baiyi Zhenhua is a rich merchant, but if you want to invest and open a shop, you don't have to go to the so-called prosperous area, because the expenses there should be high.
I recommend a potential place: Donghai Economic Development Zone, which is a potential consumer group. Although there is only one Nanshan College, there are tens of thousands of students there, and it is not convenient for them to go out.
