The farmer cooperative sector in China has experienced rapid development in the past two decades, in particular after the implementation of the Famer Cooperative Law in 2007. Farmer cooperatives are considered important to mediate between farmers and other actors in the wider social, economic and political environment. Farmer cooperatives also can provide relevant services to improve production and marketing and enhance agricultural and rural development. This thesis investigates how Chinese farmer cooperatives coordinate production and marketing activities of farmers and act as intermediaries in relation to external actors. Central to the research are both the processes and outcomes of intermediation.
