In Fujian Quanzhou, the social security contribution base of 10,100 yuan is not directly classified into a specific "file." Social security contribution bases in Quanzhou are generally determined as a percentage of the local average wage of employees in the previous year, and are usually divided into multiple levels such as 60%, 80%, 90%, 100%, 150%, 200%, 250%, and 300%. To determine which "file" 10,100 yuan corresponds to, it is necessary to first know the local average wage of employees in the previous year in Quanzhou. For example, if the local average wage of employees in the previous year in Quanzhou is 15,000 yuan:

1. Calculation of different levels of contribution bases:

• The contribution base at 60% is ​
  ×60%=
  yuan.

• The contribution base at 80% is ​
  ×80%=
  yuan.

• The contribution base at 100% is ​
  ×100%=
  yuan.

2. Judgment of the corresponding level: Since 9000 yuan (​
   60%
   level) < 10,100 yuan < 12,000 yuan (​
   80%
   level), in this case, a contribution base of 10,100 yuan is between the 60% and 80% levels. But if the local average wage of employees in the previous year is different, the result will also change. For instance, if the local average wage of employees in the previous year is 12,000 yuan:

• The contribution base at 60% is ​
  ×60%=
  yuan.

• The contribution base at 80% is ​
  ×80%=
  yuan.

• The contribution base at 100% is ​
  ×100%=
  yuan.

• Since 9600 yuan (​
  80%
  level) < 10,100 yuan < 12,000 yuan (​
  100%
  level), at this time, a contribution base of 10,100 yuan is between the 80% and 100% levels.

In general, to accurately determine which level the social security contribution base of 10,100 yuan in Quanzhou belongs to, it is necessary to compare it with the local average wage of employees in the previous year in Quanzhou.
