This study examines Chinese consumers’ concern about books on online bookstores. To address this, four research questions are proposed. The data used in this study are collected from the book best-seller lists from the most popular online bookstores in China, which is Dangdang.com. It is found that the most Chinese consumers are mainly concerned with fiction, children’s books, inspirational books and books about life. Secondly, the exponential Smoothing is used to predict the book short-term attention. And the reasonable results prove that the prediction method chosen is appropriate. Lastly, based on the data on consumers’ preference on themes of the books from 2004 to 2011, we find that fiction is always ranked in the first place. At the same time, the other popular top-ranking themes are children book, health/mental health, and management.
