This comparative research project looks at the co-operation between state and social organizations (SOs) in China and Germany. It focusses on social service delivery in the area of integration of migrating populations with special attention to the fields of education, employment, vulnerable groups and social assistance (incl. legal aid) as a crosscutting issue to all of the fields. Within this subject area, the project wants to identify different models of state-SO co-operation and analyze which models are successful and why and where this co-operation is problematic. It aims to capture the different models of co-operation in Germany and China, to analyze and compare the underlying structures and to show potentialities for development.
