With the globalization of technology and the changes of society，the boundaries between childhood and adulthood have become increasingly blurred. Children’s studies begin to re-examine the modern thinking and the binary opposition in childhood research，and propose that in order to adapt to the diversity and continuous influence of childhood，childhood research must find and effectively use non-dualistic theoretical analysis resources. On the one hand，“actor-network theory” and “complexity theory” have provided such research with theoretical basis，spanning the dualistic perspective，focusing on the long-term effects of childhood on individual publicity and the public participation of children. On the other hand，ICT（Information and Communication Technology） and community engagement play an important role in the construction of contemporary childhood，especially for the vulnerable groups of children to gain public participation and to enter the public domain. Childhood research requires a broad theoretical perspective and an interdisciplinary approach，and it also requires attention to the processes and mechanisms of the effects brought by children’s engagement on the acquisition of individual publicity. How to effectively use information technology to promote public participation，and how to expand the existing public space to form an effective connection with realistic community participation are the keys to realizing a “good society” for children’s future.
