The comparative study of China's mega‐city regions: A perspective of competitiveness.

Mega‐city regions (MCRs) have emerged as the main spatial form of China's new urbanization strategy and become the basic spatial units participating in global and regional competition. However, MCRs are not equally capable of boosting regional economic development due to their different levels of development. Therefore, this paper adopts the concept of competitiveness as both a theoretical framework and an empirical model to evaluate the development status of China's MCRs. Based on a review of the existing literature, this paper proposes a multi‐tier evaluation system to calculate the competitiveness of 13 MCRs. The chosen indicators come from the six perspectives of economic development, human resources, infrastructural accessibility, integration into the global economy, capacity for scientific and technological innovation, and sustainable development. The results show that there are great disparities and regional inequalities in competitiveness across different MCRs. The Yangtze River Delta, Pearl River Delta, and Beijing–Tianjin–Tangshan MCRs are the first‐tier MCRs with the highest levels of development and have significant global influence as well. Chengdu–Chongqing, Shandong Peninsula, South‐central Liaoning, and Wuhan belong to the second‐tier of MCRs that show partial advantages and have significant regional influence. The remaining regions belong to the third‐ or fourth‐tier of MCRs that have relatively weak competitiveness. The competitiveness of MCRs largely depends on the concentration of core elements in core cities. [ABSTRACT FROM AUTHOR]
