There is no difference in essence, and everyone's functions and business are the same. Mainly the difference in competitiveness. Large securities companies are relatively strong, with many subsidiaries, convenient operation and good reputation. Some service charges are still low. Usually, most of the big securities companies are in Shanghai and Shenzhen, because this is the place where China's stock developed earliest and has the privilege of special economic zones. Such as junan securities.
Locally, the stock market has developed to a certain extent. In order to avoid monopoly and enhance competition, local securities companies are allowed to be established.
Because the local service fee is very low, and small and medium-sized retail investors do not give up. In recent years, large securities companies mainly put everything on big customers. So many citizens still like local securities ~!
