This paper concentrates on China’s partner assistance phenomena. It adopted network analysis methods, task-orientated organization theories and institutional evolution theories to construct an analysis framework for task-orientated intergovernmental network, and apply it to analyze China’s partner assistance practices since the 1980s. The results show that China’s partner assistance virtually builds a task-orientated intergovernmental network. This network is evolving under overlapping, embedding and reconstructing effects. According to the emergence and development process of task-orientated intergovernmental network, China’s central government plays a critical role in this process. The relationship between nodes, the relations between assistance providers and recipients are not properly, many interactions among local governments need to be formalized.
