Zibo, where employees of Shandong state-owned enterprises are located, began to pay personal social security that year.

As far as I know, Shandong Province began to implement the Interim Measures for the Administration of Social Insurance for Employees of Institutions in Shandong Province on 1992, and regulated and managed the social insurance for employees of institutions in Shandong Province. According to this time node, it can be considered that 1992 is the starting year for employees of Shandong state-owned enterprises to pay personal social insurance. It should be noted that the specific start-up time may be different for different state-owned enterprises. It is suggested that you can also consult relevant policies and regulations to obtain more accurate information. If you need a more detailed answer, I suggest you consult the local government or relevant departments.
