With the development of the Internet in China, people have increasingly turned to digital communication and networking tools for personal connections and social relations. From messaging and dating apps to microblogging and live-streaming platforms, mediated forms of sociality constitute a significant part of people’s intimate lives. Scholarly works on modern and contemporary China have shown how practices and politics of intimacy are formulated and contested against the backdrop of the tensions between the residual culture of Confucianism, the socialist ideological regime, and China’s participation in global capitalism. On the contrary, research on global network societies has foregrounded the role of information and media technologies in mediating intimacy with conceptual frameworks such as programmed sociality and networked intimacy. Bridging these two areas of research, this essay attempts to understand how intimate sociality is configured within China’s burgeoning digital economy and culture. It first provides a review of previous works on forms of intimacy and sociality mediated by network technologies ranging from mobile phones to online dating. Using the popularity of live streaming in current-day China as a case study, this essay then introduces the problem of “scale” to consider how intimacy is mediated at scale with Internet-based media technologies and discuss how scalability shapes intimate lives in Chinese society as a shared rationale behind modernization, network technologies, and new forms of economies. This essay proposes the concept of scalable intimacy to move beyond the platform-centered approach and develop a more contextualized framework for understanding intimate sociality in digital China.
