Abstract

In this paper, Barro regression model is constructed by using urban per capita GDP and the shortest transportation distance, and the border effect of Pan-Pearl River Delta region in 2011-2021 is measured in stages. The results show that: (1) the convergence of economic development in this region is strong at first and then weak, especially in Guizhou and Guangxi; (2) The inter-provincial border shielding effect is weakened, but the intermediary effect is enhanced, but the intensity is low, which shows that the boundaries of intermediary effect have increased from 8 in the first five years to 11 in the last five years, and the border shielding effect in Guizhou is stronger; (3) Traffic improvement has promoted urban economic growth, but it has no significant impact on inter-provincial economy, and the influence of distance factors has weakened.
