Dynamics, space, and regional inequality in provincial China: A case study of Guangdong province

► This paper investigates regional inequality in Guangdong province, China. ► It follows the multi-scale and multi-mechanism framework. ► We have found a new round of intensifying inequality since the early 2000s. ► We have identified the core-periphery hierarchy of multi-mechanisms. ► Policies are constrained by geographical barriers and the agglomeration effect.
