China’s subnational policies and the performance of provinces towards meeting the UN’s Sustainable Development Goals

China has recorded impressive economic achievements driving the structural transformation of its society. However, this transformation is marked by rising inequality, environmental pollution and stark provincial disparities. In 2015, the launching of the Agenda 2030 provided a common ground at the international level conceptualizing the United Nations’ Sustainable Development Goals (SDGs). This paper analyses the provincial performances towards the Agenda 2030 in the period 2015–19 by introducing the integrated sustainable development index cluster; convergence and econometric analyses are then used to explore synergies and trade-offs among SDGs. The empirical results capture the dynamics of sustainable development of China’s provinces and provide a clearer understanding of how policies may influence different the SDGs’ achievements, exploring the relationship between environmental versus different aspects of development. These results are used to draw policy recommendations that highlight the importance of identifying the appropriate mix of strategies to promote integrated sustainable development.
