摘　　要：科学量化淮海经济区工业碳排放效率并分析其网络结构特征对于推动工业低碳发展具有重要意义。采用非期望产出SBM模型、引力模型、社会网络分析法分析2010—2020年淮海经济区工业碳排放效率及其空间网络结构特征,研究发现:①2010—2020年淮海经济区工业碳排放效率提升较快,整体呈现徐州—菏泽一线地区高而两侧低的“凸”字形空间格局;②研究期内淮海经济区工业碳排放效率空间关联网络的网络关系数、网络密度和网络效率下降,网络等级度上升,网络结构的稳健性有待加强,徐州在网络中的绝对中心性地位增强,发展协调性有待提高;③利用块模型将淮海经济区划分为净受益板块和净溢出板块,板块内部联系较少。Scientifically quantifying the industrial carbon emission efficiency of the Huaihai Economic Zone and analyzing its network structure characteristics are of great significance for promoting its industrial low-carbon development.This paper adopts the unexpected output SBM model,gravity model and social network analysis methods to analyze the spatial network structure characteristics of industrial carbon emission efficiency in the Huaihai Economic Zone from 2010 to 2020.It is found as follows.①The industrial carbon emission efficiency of the Huaihai Economic Zone has improved rapidly,and overall,it presents a"convex"spatial pattern with a high level in the area along Xuzhou-Heze and a low level on its both sides.②During the study period,the network correlation number,network density and network efficiency of the spatial correlation network of industrial carbon emission efficiency in the Huaihai Economic Zone decreased,the network grade increased,and the robustness of the network structure needed to be strengthened.The absolute centrality of Xuzhou in the network has been strengthened,and the coordination of development needs to be improved.③Using the block model,the Huaihai Economic Zone is divided into net beneficial plate and net spillover plate,and there are few internal connections between the plates.
