The difference between provident fund and social security is as follows: 1. Provident fund refers to housing provident fund. Housing accumulation fund refers to the long-term housing savings paid by state organs, state-owned enterprises, urban collective enterprises, foreign-invested enterprises, urban private enterprises and other urban enterprises, institutions and their employees. Social security refers to a non-profit social security system with the function of income redistribution for the purpose of preventing and forcing most members of society to participate. 2. Social insurance is a social and economic system that provides income or compensation for people who have lost their ability to work, are temporarily unemployed or suffer losses due to health reasons. The social insurance plan is organized by the government, forcing a certain group to use part of its income as social insurance tax (fee) to form a social insurance fund. Under certain conditions, the insured can get fixed income or loss compensation from the fund. It is a redistribution system, and its goal is to ensure the reproduction of material and labor and social stability. The main items of social insurance include endowment insurance, medical insurance, unemployment insurance, industrial injury insurance and maternity insurance.
