Matching insurance premium system: that is, regardless of the income of the insured or his employer, the same amount of insurance premium will be charged. The advantages of this system are simple calculation and easy to be universally realized. Moreover, in countries that collect insurance premiums in this way, the payment system is generally divided equally, which has the significance of equal income and expenditure. But its defect is that low-income people and high-income people pay the same premium, which is obviously unfair in terms of affordability. The sharing subjects of social insurance premiums are countries, enterprises and individuals. The different combinations of these three subjects have produced many ways of sharing expenses. The payment base of social security refers to the wage base used by enterprises or employees to calculate and pay social insurance premiums. This base multiplied by the prescribed rate is the amount of social insurance premiums that enterprises or individuals should pay.
Local social security payment bases are linked to local average wage data. It is determined according to the average monthly wage income of employees from June 1 day to February 1 day in the previous year. Once a year, it will not change within one year after confirmation. The time to apply for adjusting the social security base is generally in July. Enterprises generally take the total wages of enterprise employees as the payment base, and individual employees generally pay social insurance premiums based on their average monthly salary in the previous year. In China, the payment base is approved by the social insurance agency according to the employer's declaration. Payment ratio, that is, the collection rate of social insurance premiums. China's "Social Insurance Law" does not make specific and clear provisions on the collection rate of social insurance. According to China's current social insurance policy, we implement different collection ratios for different types of social insurance.
