Abstract:

With the recent spread of emerging ‘urban diseases’ and the uncertainty of major public events, resilient cities are becoming a priority for urban development. Considering the regional integration in the Yangtze River Delta as national strategy, the article uses entropy-comprehensive index method to calculate the elastic construction level of 41 cities in the region from 2003 to 2018. Besides, a spatial analysis method was used to investigate the spatial distribution characteristics. Our findings show that: 1) The comprehensive elasticity index of all cities in the study area is on the rise, and the gap between cities is narrowing. A high-level elastic city pattern has been formed along the Yangtze River, around the Hangzhou Bay and in the southern Zhejiang Province. However, most of the peripheral areas of the Yangtze River Delta, such as northern Anhui Province and the northern Jiangsu Province, are still at a low elasticity level. 2) The elasticity indexes of all cities have obvious spatial clustering characteristics. ‘High-High’ clustering appears in Shanghai and its surrounding cities, ‘Low-Low’ clustering appears in northern Anhui Province and northern Jiangsu Province, and ‘Low-High’ clustering appears in Huzhou, Xuancheng and other cities. 3) The distribution of engineering, social and economic elasticity characteristics are relatively consistent, which are relatively high in the municipality directly under the central government, provincial capital and economically strong city. However, the level of urban ecological resilience in the study area is generally low. The results suggest that urban engineering, social and economic resilience construction in the Yangtze River Delta region should pay attention to narrowing the regional gap in the future, the regions with better natural background should strengthen the maintenance of ecological environment, and the economically developed regions should improve the level of ecological environment governance.

Key words: regional integration, elastic city, entropy method, spatial autocorrelation, Yangtze River Delta region
