Home Internet adoption in rural societies deserves more attention. Through a survey of 480 rural residents in a typical central China province, this study supports the central role of knowledge in the adoption process. Results show that the low adoption rate of the Internet in rural China is directly caused by people’s low levels of knowledge about the Internet. Although attitude is positively influenced by knowledge, the former plays a weaker role than the latter in rural residents’ adoption of the Internet. This is why people with minimum Internet knowledge would not adopt the Internet even if they have a relatively positive attitude toward it. In addition, this study has supported the contributing effects of mass media use on the acquisition of Internet knowledge. Implications and limitations of the study are discussed.
