This book is devoted to illustrating the significance of perpetrator-victim relationship, including its status and state, in understanding intimate partner homicide (IPH) in the context of China today after comparing with the findings in the previous studies. By analyzing the correlation between intimate relationships as a focal variable and other variables such as IPH characteristics and risk factors, a deeper understanding of IPH in China today has emerged. Finally, this book shows that many perpetrators and victims had intimate relationships with people outside their marriages as the main reason for the rapid increase in the number of instances of IPH, which seems to be in tandem with China's rapid modernization and urbanization. Presenting the sole academic research that closely investigates the characteristics of intimate partner homicide in modern China, the book is a valuable resource for not only for the Chinese government but also for Chinese and international researchers.
