Assessing the evolution and convergence of energy-related carbon emission efficiency in the Yangtze River Economic Belt
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.
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.
