Abstract

The clean energy transition effectively improved air quality, but also stimulated energy consumption and economic performance, causing complex impacts on overall energy efficiency. So what is the comprehensive impact of energy transition on energy efficiency considering air pollution? This paper used the stochastic frontier method to calculate the green energy efficiency of prefecture-level cities based on 7 years panel data of 280 prefecture-level cities in China, and adopted group-timing treatment effect estimator to study the dynamic and heterogeneous impact of Central Financial Support for Winter Clean Heating Pilot in the Northern Region on green energy efficiency. The results indicate the pilot increased cities’ green energy efficiency by an average of 0.00444. The improvement was significant only in early group of year 2017 and 2018, and the clean heating policy enhanced green energy efficiency after three years of implementation. Clean heating pilot affects green energy efficiency by improving air quality, stimulating energy consumption directly, and promoting green technology innovation indirectly, with enhance green energy efficiency of neighboring cities simultaneously. Our findings provide useful references for balancing environmental protection and economic development, as well as achieving sustainable energy utilization.

冬季清洁供暖试点对中国绿色能源效率的影响——基于多周期差中差法

清洁能源转型有效改善了空气质量，但也刺激了能源消耗和经济绩效，对整体能源效率产生了复杂的影响。那么考虑到大气污染，能源转型对能效的综合影响是什么呢？本文基于中国280个地级市7年面板数据，采用随机前沿法计算地级市绿色能源效率，并采用组时处理效果估计器，研究中央财政支持北方地区冬季清洁供暖试点对绿色能源效率的动态和异质影响。结果表明，试点城市绿色能源效率平均提高0.00444。仅在2017年和2018年上半年，这一改善是显著的，清洁供暖政策在实施三年后提高了绿色能源效率。清洁供暖试点通过改善空气质量、直接刺激能源消费、间接促进绿色技术创新来影响绿色能源效率，同时提高周边城市的绿色能源效率。研究结果为平衡环境保护与经济发展，实现能源的可持续利用提供了有益的参考。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
