Studies on welfare model selection can be conducted from the perspectives of welfare demand and welfare multisupply As far as the development of welfare states is concerned, welfare demand and supply are both embedded in the environment of the economic society A case study conducted in T city of south Jiangsu Province finds that the background of social transformation determines its complexity in the structure of welfare demands, thus a comprehensive and pluralistic welfare model is required to address the situation But in terms of welfare supply, it is reflected as the everexpansion of governmental role and the corresponding shrinkage of both the market and the society In a complicated demand structure, welfare under monopoly government should be carefully avoided and a comprehensive welfare system be set up, through the combination of “civil society” and “government of limited liability”.
