France has one of the most generous welfare systems in the world. The French welfare system，created after World War II，provides French citizens with comprehensive protection，from the cradle to the grave. However，in the new era of globalization，the French welfare state is confronted with increasingly severe challenges such as financial unsustainability，low cost performance etc. That’s why the French President Macron has promised to reshape it since coming into power. According to him，French welfare state is wasteful，unfair and has failed to rescue the poor from poverty. Inspired by the Nordic model，he has launched a series of reforms in the fields of pensions，unemployment insurance and employment，poverty reduction and prevention of poverty，aimed at building a welfare state for the 21st century，which would be better adapted to the modern labor market and better cope with the challenges associated with an ageing society. These measures reveal that France’s welfare state is moving away from a redistributive model to a Nordic-style system of “flex-security”，and from social protection to social investment. In short，Macron strives to balance efficiency and equity and thus ensure that the French welfare state could be sustainable in the medium and long run.
