| 摘 要: | 黄河流域生态保护和高质量发展是重大国家战略,产业生态化是在保证经济持续稳定增长的同时保持重要生态系统完整性、资源配置合理性以及兼顾紧密联系区域实际状况的有效路径。本文以黄河流域为研究区域,产业生态化为研究对象,讨论产业生态化效率空间差异及导致差异的影响因素,旨在为地区间的比较分析、各地区自身的发展方向提供参考。本文采用超效率SBM模型测算了黄河流域59个市州2001~2020年产业生态化效率,利用基于Driscoll-Kraay标准误的双固定效应回归模型和地理探测器探究研究区产业生态化效率的空间异质性、驱动因子及其相互作用。结果表明:1. 在研究区域内产业生态化效率空间分异特征显著,呈现出以省会城市为高值点向四周递减扩散的空间格局。2. 技术创新、环境管制、产业结构和对外开放均对产业生态化效率的提高具有影响,且因自身的空间分布影响产业生态化效率的空间分布。3. 各个驱动因子对产业生态化效率及其空间异质性的影响效果并不相同。4. 各因子之间的交互作用对产业生态化效率的影响优于单因子的效果。 |

| Abstract: | Ecological protection and high-quality development of the Yellow River Basin are major national strategies, and industrial ecology is an effective way to maintain the integrity of important ecosystems, rational resource allocation and take into account the actual situation of the region while ensuring sustained and stable economic growth. Taking the Yellow River Basin as the research area and industrial ecology as the research object, this paper discusses the spatial differences in industrial ecological efficiency and the influencing factors that lead to them, aiming to provide reference for the comparative analysis of regions and the development direction of each region. In this paper, the industrial ecological efficiency of 59 cities and prefectures in the Yellow River Basin in 2001~2020 was calculated by constructing a super-efficient SBM model. The double fixed effect regression model based on Driscoll-Kraay standard error and geographic detector model were used to explore the spatial heterogeneity and driving factors of industrial ecological efficiency in the study area, and how these driving factors affected the spatial distribution of industrial ecological efficiency. The results show that: 1. The spatial differentiation characteristics of industrial ecological efficiency in the study area are significant, showing a spatial pattern of decreasing diffusion from provincial capital cities as high-value points. 2. Technological innovation, environmental control, industrial structure and opening up all have an impact on the improvement of industrial ecological efficiency, and will affect the spatial distribution of industrial ecological efficiency due to its own spatial distribution. 3. The influence of each driving factor on industrial ecological efficiency and spatial heterogeneity is different. 4. The influence of the interaction between factors on industrial ecological efficiency is better than that of single factor. |
