The wellbeing eco-efficiency (WEE) is a core indicator for assessing the quality of regional ecological environment and people’s livelihood. Clarifying its spatial temporal dynamic evolution network structure characteristics crucial promoting protection high-quality development in entire Yellow River Basin (YRB). Based on panel data 99 cities YRB from 2010 to 2022, WEE measured by introducing into evaluation system eco-efficiency. spatial-temporal dynamics, disparities, their origins, as well structural attributes network, are investigated. results showed that: First, YRB, upper, middle, lower reaches have been improved, showing stage “steady growth-fluctuation decline-rapid growth,” technological progress main driving force efficiency growth. Second, absolute difference whole middle shows an expanding trend, upper show decreasing trend. inter-regional differences hypervariable density sources differences. Third, has broken geographical location restrictions formed multi-threaded complex form. During sample investigation period, scale agglomeration continuously enhanced, small-world correlation effect significant. Forth, regarding small group characteristics: reaches’ “wheeled” centered Longnan; forms “chain” with Yulin, Xi’an, Ankang cores; exhibits “dual-core multi-center radial” Heze Zhengzhou at core, featuring significant two-way interactions.
