Abstract

This paper examines the spatiotemporal evolution and convergence of energy-related carbon emission efficiency in the Yangtze River Economic Belt (YREB) using prefecture-level data from 2012 to 2021. Employing the SBM-GML strategy, kernel density estimation, the Dagum decomposition method, and the spatial econometric model, the study identifies three main findings: (1) The energy-related carbon emission efficiency in the YREB demonstrates a phased upward trend, particularly after 2014. (2) Pronounced regional disparities are observed, with downstream areas displaying higher efficiency compared to midstream and upstream regions, driven primarily by notable density variations and intra-regional disparities. (3) The analysis reveals both σ-convergence and β-convergence dynamics, highlighting varied spatial effects across regions. Factors such as economic development, industrial structure, and financial incentives exhibit diverse impacts on efficiency, underscoring substantial heterogeneity. This study offers empirical insights crucial for enhancing energy-related carbon emission efficiency in pivotal economic zones.

评估长江经济带能源相关碳排放效率的演变与趋同

本文利用 2012 年至 2021 年的地级市数据，研究了长江经济带（YREB）能源相关碳排放效率的时空演变和收敛。采用 SBM-GML 策略、核密度估计、Dagum 分解法和空间计量经济模型，研究发现了三个主要结论：（1）长江经济带能源相关碳排放效率呈现阶段性上升趋势，尤其是 2014 年以后。(2）观察到明显的区域差异，与中游和上游地区相比，下游地区的效率更高，这主要是由显著的密度差异和区域内差异驱动的。(3) 分析显示了 σ 趋同和 β 趋同动态，凸显了各地区不同的空间效应。经济发展、产业结构和金融激励等因素对效率的影响各不相同，凸显了巨大的异质性。这项研究为提高枢纽经济区与能源相关的碳排放效率提供了重要的经验启示。

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
