Spatiotemporal Characteristics and Differentiation Mechanisms of Market Segmentation in China’s Urban Agglomerations
This study employs methods such as the Dagum Gini coefficient and spatial kernel density estimation to demonstrate that market segmentation in China’s urban agglomerations exhibits a fluctuating downward trend, that regional disparities are mainly attributable to super-variable density, and that both club convergence and spatial convergence effects are present. It further reveals the driving mechanisms of spatial differentiation arising from multiple factors—including fiscal decentralization—and their interaction effects, thereby providing important empirical evidence for the construction of a unified national market.
