Abstract: The important reason for the rapid development and too big to be cut down of modern welfare state is that it can objectively play the role of social control. The Poverty Relief Law System in the early industrialization of Britain, the social insurance legislation of the Deutsches Reich, and the social stratification of the social welfare policy of the United States all have very important social integration functions, and many of them are also socially compulsory. However, Bismarck’s social insurance legislation in order to achieve better social control has been gradually adopted by most European and American countries. Objectively, the Western welfare state has played a good social control effect: through the welfare state, it can achieve effective social control and social redistribution of social resources such as population, information, population mobility and national wealth. Through the welfare state to achieve social control and integration function, we can learn from our national state and social governance, but the specific methods need to be optimized and improved to enhance the governance level and capacity of our country.
