Spatio-Temporal Differentiation Mode and Threshold Effect of Yangtze River Delta Urban Ecological Well-Being Performance Based on Network DEA

Improving ecological well-being performance (EWP) is the essential requirement of green transformation development and civilization construction. With help a network DEA model threshold panel regression model, this study evaluated urban to explore evolution process, impact, optimization path in Yangtze River Delta from 2001 2017. The findings are as follows: (1) all cities region had been steadily improving since 2001, most realized low level higher level, there was an obvious spatial mismatch between economic performance. (2) A regional mode constantly optimized, sustainable ability improved, number high-high (HH) gradually increasing while low-low (LL) decreasing. (3) Under influence variables population density, industrialization environmental regulation, impact urbanization on different characteristics. Economic growth, industrialization, government macro-control significantly negative restraining effects, consumption industrial structure upgrading, energy efficiency, technological innovation positive driving effects.
