Megaregions are the new form of Chinese-style urbanisation. China’s new discourse of ‘high-quality development’ and ‘new-type urbanisation’ is reshaping its megaregional strategy. Imbalance and fragmentation characterise the diversity of megaregions - developed or developing, coastal or inland. The central goal of megaregional planning and governance is to achieve integrated, balanced development of them. Hu challenges the official notion of ‘top-level design’ that dominates the planning, governance, and development of China’s megaregions. Instead, he argues for the importance of engaging nongovernmental stakeholders, rebalancing the government-market relationality, encouraging bottom-up initiatives, and enabling grassroots ingenuity. The volume offers the first and most comprehensive study of megaregional China in the new contexts of both national development and urban development. It will be of interest to anyone looking into urban and regional development, and Chinese studies.
