Resumen
This article examines the interplay between welfare ideas and institutional development and then seeks to explore the ideational background for social policy expansion in China. It focuses on the welfare semantics and narratives that underpin the grand social policy transformation since the millennium. The primary research question concerns whether the approach of “sustainability” is related to social policy in China, and, if yes, how and to what extent. Through the analysis of academic literatures and government documents on social policy in China, we explore the new “sustainability approach” to Chinese social policy that is constructed by social experts and international agencies. While the old sustainability approach overwhelmingly links the “sustainable development” of social policy to the issue of financial affordability and the adequacy of benefit levels, the newly interpreted approach highlights the significant meaning of social policy for long-term and inclusive development over the upcoming decades. Against this backdrop, a holistic national plan for socio-economic modernization has incorporated social policy. Beyond economic and ecological objectives, social development with a focus on social policy has become a key pillar of sustainable development in China.
