协调好湟水流域产业结构升级与生态保护的关系,对推动黄河流域高质量发展、祁连山生态屏障建设及区域可持续发展意义重大.基于湟水流域西宁段7县区2010-2021年面板数据,运用Super-Undesirable SBM模型和扩展的耦合协调模型对产业结构升级、生态效率提升及两系统耦合协调水平进行测算评价,并借助坐标分类法对路径进行识别.结果表明:(1)样本区产业结构升级与生态效率提升水平区域差异显著,且呈现出"中心凸出、两边薄弱"的空间分布.(2)样本区内各县区整体耦合协调水平不高,区域差异显著,且大部分处于过渡耦合阶段,弹性较弱.(3)产业结构升级固化是该区域耦合协调水平较低的主要制约;耦合路径发展中应重点关注"双低"类型区域,同时避免陷入"低水平协调"陷阱.最后从内部突破资源约束与外部实现制度均衡分配2个维度提出相关发展建议.研究结果可为实现湟水流域西宁段高质量发展提供参考.
This study utilizes panel data spanning 2010 to 2021 from seven counties and districts within the Xini-ng section of the Huangshui Basin.Employing the Super-Undesirable SBM model and an extended coupling coor-dination model,we assess the levels of industrial structure upgrading and ecological efficiency enhancement.Ad-ditionally,we evaluate the coupling coordination between these two systems,identifying optimal paths through the coordinate classification method.The findings reveal:(1)Substantial regional variations exist in both industri-al structure upgrading and ecological efficiency enhancement across the sample area.The spatial distribution ex-hibits a pattern of prominence in the center and weakness on the sides.(2)The overall coupling and coordination levels among the counties and districts demonstrate a lack of high coherence,marked by significant regional dis-parities.Most areas fall into the transitional coupling stage with weak elasticity.(3)The solidification of industri-al structure upgrading emerges as the primary impediment to achieving a higher level of coupling coordination in the region.Developing coupling paths should prioritize regions characterized by the"double-low"type,steering clear of the pitfalls associated with"low-level coordination".In conclusion,this study recommends internal break-throughs to address resource constraints and external strategies to achieve a balanced distribution within the systems.
