It is stipulated that the employer's contribution rate should be controlled at about 6% of the total wages of employees, and calculated according to the principle that the level of basic medical insurance is compatible with the development level of productive forces in the primary stage of socialism in China and the actual affordability of finance and enterprises.

According to statistics in recent years, the proportion of medical expenses actually incurred by employees in China is about 10%, of which the proportion of medical expenses actually borne by finance and enterprises is about 7% of the total wages. After deducting the expenses of retirees and college students who are not in the basic medical insurance coverage, industrial injury and maternity medical expenses of enterprises, the proportion of medical expenses actually borne by finance and enterprises is about 6%. 6% is the basic medical insurance cost that the national average finance and enterprises can pay.

Therefore, from the national level, taking about 6% as the control standard of the national employer's contribution rate is in line with the current level of productivity development in China, which can be borne by both finance and enterprises.

However, national control standards can be measured at the national level. Due to the great difference in medical consumption in China, 6% cannot be used as the absolute control standard of the national employer's contribution rate. For specific areas, the payment ratio of employers should be reasonably determined according to the actual affordability of local finance and enterprises.
