Abstract: Government-society relationship plays an important role in innovating China's governance system. This research studied the evolution of International Non-Government Organization (INGO) policies in Yunnan and developed a "collaborative framework" of government-society relationship, which aims at solving regional development needs. Results show that the implementation of INGO policies largely relies on the intra-government cooperation and on the government-INGO collaboration to provide social services. To further explore a sustainable government-society relationship, institutional innovation and a more service-oriented governance system are needed.
