Aims: Hyperlink analysis is used to evaluate the relative performance of Chinese government websites in delivering information regarding HIV, by comparing with other sources of public health information, including NGOs and government agencies from other countries.  Data and Methods: Hyperlink data collection and analysis was conducted using the Virtual Observatory for the Study of Online Networks (VOSON) System (Ackland, 2009). A hyperlink network containing 738 websites -- Chinese government websites and their competitors in the field of delivering HIV information in China -- was analysed.  Results: The study provides useful and novel information on the structure of hyperlink network formed by organizations involved the provision of HIV information in China, including Chinese government departments, NGOs, media, and education and research institutions. Chinese government websites have strong visibility, but their ability to deliver information to websites in Chinese is much greater than those in English. Moreover, the capacity of Chinese government websites to offer a wide range of information is weak. Additionally, they do not play a strong role in the network in terms brokering or bridging. Conclusion: The Chinese government plays an important role for HIV prevention in China, especially in disseminating the relative information in Chinese. However, the hyperlink analysis suggests that cooperation between the government and other sectors is not very strong, and this needs to be improved if this emerging public health issue is to be adequately addressed.
