Special Issue Information

Dear Colleagues,

The transition to sustainable energy systems is essential to reducing climate change and achieving global environmental and economic goals, and this Special Issue aims to explore the interconnections between energy economics, policy-making, and technological innovation in the context of environmental sustainability. The topics of interest include energy transition policies, renewable energy integration, cost–benefit analysis of sustainable technologies, and the socio-economic effects of decarbonization policies.

This Special Issue calls for submissions that critically examine policy regimes, market forces, investment schemes, and interdisciplinary models supporting low-carbon and resilient energy futures. Through the convergence of insights from engineering, economics, public policy, and environmental science, the Special Issue seeks to result in a thorough examination of sustainable energy development.

It will complement the journal's objectives by promoting holistic sustainability assessment, implementation, and monitoring approaches, and presenting tools and case studies that can aid decision-makers in government, academia, and industry.

Achieving carbon reduction is essential in advancing China’s dual carbon goals and promoting a green transformation in the transportation sector. Changes in energy structure and intensity constitute key drivers for sustainable and low-carbon development in this field. To explore the spatial spillover effects of the energy structure and intensity on the green transition of transportation, this study constructs a panel dataset of 30 Chinese provinces from 2007 to 2020. It employs a super-efficiency SBM model, non-parametric kernel density estimation, and a spatial Markov chain to verify and quantify the spatial spillover effects of green total factor productivity (GTFP) in the transportation sector. A dynamic spatial Durbin model is then used for empirical estimation. The main findings are as follows: (1) GTFP in China’s transportation sector exhibits a distinct spatial pattern of “high in the east, low in the west”, with an evident path dependence and structural divergence in its evolution; (2) GTFP displays spatial clustering characteristics, with “high–high” and “low–low” agglomeration patterns, and the spatial Markov chain confirms that the GTFP levels of neighboring regions significantly influence local transitions; (3) the optimization of the energy structure significantly promotes both local and neighboring GTFP in the short term, although the effect weakens over the long term; (4) a reduction in energy intensity also exerts a significant positive effect on GTFP, but with clear regional heterogeneity: the effects are more pronounced in the eastern and central regions, whereas the western and northeastern regions face risks of negative spillovers. Drawing on the empirical findings, several policy recommendations are proposed, including implementing regionally differentiated strategies for energy structure adjustment, enhancing transportation’s energy efficiency, strengthening cross-regional policy coordination, and establishing green development incentive mechanisms, with the aim of supporting the green and low-carbon transformation of the transportation sector both theoretically and practically.
