Introduction: Platforms for social good.

The rise of platforms since the Millennium has drastically reshaped human activities worldwide and transformed our physical world into what is known as platform societies, wherein social and economic interactions are profoundly mediated and defined by the digital infrastructure of platforms. The immense integration of platforms into daily human life prompts inquiry into their capacity to foster social good. This Special Issue presents a compilation of articles that scrutinize the intricate relationship between platforms and their potential to promote social good in the contexts of mainland China and Hong Kong. In both settings, platforms are subject to negotiation and co-creation among technological, commercial, and political logics, although the nuances differ. While social good can embody a wide range of public interests and common goods, this Special Issue specifically explores social good within the domains of promoting good health and well-being, advocating responsible production and consumption, fostering societal equality, advancing decent work and economic growth, and supporting justice and effective institutions. The collection illustrates that platforms may contribute to social good at both macro and micro levels. Platforms have the capacity to provide infrastructure for social and economic activities in the digital realm, driving transformations in business and social relations. Platforms can also offer individuals and collectives access to resources, empowering them to safeguard public interests. Understanding the role of platforms in upholding social good requires consideration of multifaceted forces and interests rooted in the market, state, and civil society. [ABSTRACT FROM AUTHOR]
