In recent decades the Chinese financial system has undergone dramatic restructuring, which has substantially altered the country's mutual and cooperative financial institutions. This paper aims to contribute to our understanding of the process, practice and consequences of these developments by systematically charting the trajectory and dynamics of the co-operative financial landscape in China, and by analysing the role that these financial institutions have played in China's socioeconomic change. It is argued that China's financial co-operatives have been de-localised through processes of consolidation and centralisation. They have also been increasingly commercialised within a system based on 'market logic', which has changed their developmental role in the Chinese economy. At the same time, however, recent policy has sought to reinstitute locally-focused financial and farmer co-operatives in rural areas. Moreover, local informal and semiformal modes of co-operative organisation and action have continued to be widespread across the country.
