Museum networks have been in place for a long time. However, little research has been done on the phenomena of museum networks in relation to government policy. Thus, our understanding of the government’s role in promoting museum networks is very limited. Quantitative research methods were adopted in this study. In-depth interviews were conducted with academics, administrators of domestic and foreign museums, both large public and small private museums, and professionals working in relevant organizations, such as government agencies. The results indicated that most museum networks are formed as a result of government policy with the government serving as the driver of and leading force in their development. This is the case in many countries. Museums join networks not only to secure necessary resources but also to benefit from the social interactions they facilitate.
