At the earliest time, the endowment insurance was under the overall planning of the local municipal government, and the relevant departments at the municipal level were responsible for whether the pension rose, how much it rose, and whether it could be paid on time. This belongs to the period of local overall planning. Later, it became a provincial overall planning, and the pension fund was allocated by the provincial department, and the pension fund was adjusted throughout the province. Simply put, the cities in the province help each other. At present, China has basically achieved provincial overall planning. On February 22nd, 2022, Ministry of Human Resources and Social Security announced that the basic old-age insurance for enterprise employees will be launched nationwide from June 5th to 10. In this way, the pension fund has achieved national adjustment. Because the policy has just been realized, the national overall planning has not been realized. It is estimated that by mid-May, the provinces that have joined the national pension pooling system are Tianjin, Chongqing, Harbin, Xinjiang, Qinghai, Jiangxi, Shaanxi, Guangdong, Shanxi, Shandong, Fujian, Zhejiang, Hebei, Yunnan, Anhui 15 provinces and cities. At present, pension funds in some provinces are still under review and cannot be included in the national overall planning system.
