In Fujian Sanming, the social security payment base is usually set as a percentage of the local average monthly wage of on - the - job employees, generally ranging from 60% to 300% of the average wage. The 8500 social security base cannot be simply defined as a specific "file" because Sanming's social security payment files are set for different insurance types. But generally speaking, if compared with the common 60% - 300% payment base range, it is likely to be in the middle - to - high - end range:

1. For pension insurance:

• The payment base of pension insurance in Sanming is generally divided into five levels. The lower limit of the payment base of each level is 60% of the local average monthly wage of on - the - job employees, and the upper limits are 300%, 200%, 150%, 100%, and 80% respectively.

• Suppose the local average monthly wage of on - the - job employees is ​
  x
  yuan. If calculated according to the upper limit of 300% of the average wage, the upper limit of the payment base is ​
  x
  yuan; if calculated according to the lower limit of 60% of the average wage, the lower limit of the payment base is ​
  0.6x
  yuan.

• If the social security base is 8500 yuan, when the upper limit of the payment base is 300% of the average wage, assume the average wage is ​
  y
  yuan, then ​
  y=
  (the upper limit of the 2024 pension insurance payment base in Sanming), ​
  y=
  yuan. 60% of the average wage is ​
  0.6×=4432.8
  yuan. 8500 yuan is higher than 60% of the average wage (​
  4432.8
  yuan) and lower than 300% of the average wage (​ yuan). If the average wage is calculated in this way, 8500 yuan may be close to the 100% - 150% file. For example, if the average wage is 7000 yuan, 100% of the file is 7000 yuan, and 150% of the file is ​
  ×1.5=
  yuan, and 8500 yuan is between the two.

2. For medical insurance:

• The payment base of medical insurance in Sanming is generally divided into three levels, which are 100%, 80%, and 60% of the local average monthly wage of on - the - job employees.

• Similarly, taking the average wage as ​
  z
  yuan, the 100% file is ​
  z
  yuan, the 80% file is ​
  0.8z
  yuan, and the 60% file is ​
  0.6z
  yuan.

• If the average wage is 7000 yuan, the 100% file of medical insurance is 7000 yuan, the 80% file is ​
  0.8×=
  yuan, and the 60% file is ​
  0.6×=
  yuan. 8500 yuan is higher than the 100% file of the general medical insurance payment base setting in Sanming.

3. For unemployment insurance:

• The payment base of unemployment insurance in Sanming is generally divided into two levels, which are 100% and 60% of the local average monthly wage of on - the - job employees. Obviously, 8500 yuan is much higher than the 60% file (assuming the average wage is 7000 yuan, the 60% file is ​
  0.6×=
  yuan) and also higher than the 100% file (7000 yuan) in most cases.

4. For work - related injury insurance and maternity insurance:

• The payment bases of work - related injury insurance and maternity insurance are generally the local average monthly wage of on - the - job employees. 8500 yuan may be higher than the average wage (if the average wage is around 7000 yuan).

It should be noted that the specific average wage data of on - the - job employees in Sanming will change with time, and the social security payment base and file settings may also be adjusted accordingly. When determining the specific payment file corresponding to the social security base of 8500 yuan, it is recommended to consult the local social security department for the most accurate information.
