Legal analysis: although there are high and low pension standards, the standards are different, but the standards are the same, such as the proportion of Dragon Boat Festival insurance payment, pension calculation method, retirement age and so on. These standards are unified throughout the country, and all of them pay Dragon Boat Festival insurance in accordance with the provisions of the Social Security Law. Minimum payment 15 years, reach the legal retirement age, retire according to law, and retire monthly. These standards are the same all over the country. The difference lies in the level of pension benefits. China is a big country with a population of1400 million. From north to south and from east to west, the geographical environment, climate and economic development level are very different. As long as national laws and regulations are unified and major policies are unified, pension differences are allowed. The calculation of pension is based on the payment base, payment period, individual account fund balance and the average monthly salary of employees in the previous year as a comprehensive calculation tool. Due to the large difference in payment bases across the country, the average monthly salary of employees in the country is not uniform, which is the main reason for the difference in pensions.
