The relationship between industrial structure (IS) and eco-efficiency (EE) is intricate with mutual influence and constraint. Exploring the coordinated relationship between IS and EE is beneficial to the sustainable development of ecologically fragile areas. This paper estimates and analyses the levels of EE and IS in 39 prefecture-level cities of the Loess Plateau, discussing the comprehensive and coordinated development levels between industrial structure rationalization (ISR) and EE, industrial structure advancement (ISA) and EE based on the coupling coordination degree model (CCDM). The results showed that the comprehensive development of the Loess Plateau has rough and imbalanced issues. The EE and IS are developing at a relatively low level, and the spatial distribution shows the development trend of high in the east and down in the west. The CCD of ISA and EE performs better than that of ISR and EE, but neither has reached the collaborative coupling state. The poor CCD score in the Loess Plateau is primarily attributable to its relatively backward degree of integrated EE and IS. The results are expected to provide decision-making support for EE improvement and industrial restructuring in the Loess Plateau and other ecologically fragile areas.
产业结构（IS）与生态效率（EE）之间的关系错综复杂，存在相互影响和制约。探索IS与EE之间的协调关系有利于生态脆弱地区的可持续发展。本文对黄土高原39个地级市的EE和IS水平进行了估算与分析，基于耦合协调度模型（CCDM）探讨了产业结构合理化（ISR）与EE、产业结构高级化（ISA）与EE之间的综合协调发展水平。结果表明，黄土高原的综合发展存在粗放和不均衡问题。EE和IS处于较低发展水平，空间分布呈现东高西低的发展趋势。ISA与EE的耦合协调度（CCD）表现优于ISR与EE，但两者均未达到协同耦合状态。黄土高原CCD得分较低主要归因于其综合EE和IS程度相对落后。研究结果有望为黄土高原及其他生态脆弱地区提高EE和产业结构调整提供决策支持。
