Abstract:

Clarifying the synergistic mechanisms among new-quality productive forces， digital economy， and ecological efficiency （NDE system） is of significant strategic importance for achieving a green transition in the development model and a shift in growth drivers in the Yellow River Basin. Taking the 57 prefecture-level cities in the Yellow River Basin as the research subjects， this study constructs an NDE system evaluation index system and comprehensively employs methods such as the coupling coordination model， the gravity model， and the geodetector to conduct an empirical analysis of the coupling coordination among the three elements and their evolution patterns from 2010 to 2021. The study reveals that： （1） The coupling coordination of the NDE system exhibits an overall upward trend， forming a pattern characterized by high levels in the southeast and low levels in the northwest， with significant spatial differentiation； （2） The spatial connectivity network has evolved from “local agglomeration” to “region-wide linkage，” forming a multi-core radiation pattern； （3） The driving mechanism has shifted from early government-led initiatives to a diversified synergy driven by opening-up； the interactive effect between transportation location and industrial structure （q=0.981） has become a key driving force， with the interaction among various factors exhibiting nonlinear amplification characteristics. While the coordinated development of the NDE system in the Yellow River Basin has achieved results， it remains uneven. There is an urgent need to implement differentiated regional strategies， optimize diversified driving mechanisms， and improve the spatial coordination network.
