Spatial Distribution and Factors Influencing Ecological Efficiency of the Yellow River Basin in China

Improving urban ecological efficiency is an integral part of protection and high-quality development the Yellow River Basin. We used super-efficiency slacks-based model with unexpected output to measure 62 prefecture-level cities in Basin from 2005 2018. Its spatial distribution characteristics convergence are discussed. The influencing factors spillovers assessed through Dubin model. results show that: 1) highest lower reaches Basin, mid-level upper reaches, lowest middle reaches. 2) There no σ but there absolute β conditional convergence. 3) Economic development, financial technological innovation significantly promote efficiency, spillover effects significant. Increased connection outside world can improve apparent effect for these connections. industrial structure urbanization rate reduced have a significant negative effect. energy consumption reduces level not
