电力行业是中国碳排放的主要来源，因此，针对该行业推进碳减排至关重要。本研究以中国地区由燃煤火电厂和下游电网企业组成的电力供应链为主要研究对象。从可持续发展的视角出发，对中国所在省市PSC的可持续绩效和技术异质性进行了探讨和分析，提出了评价PSC可持续绩效、代际绩效和销售绩效的双系统模型。此外，为了了解PSC的技术水平，本研究应用元前沿技术分析了不同地区所有PSC的技术异质性。在此基础上，应用所提出的模型对中国所在的省级电力供应链的可持续绩效进行了分析。实证结果表明，中国电力行业的市场化改革对中国所在电网企业的发展起到了促进作用，但对电网企业的影响有限。研究还表明，中国的PSC在可持续绩效和技术上存在显著的地区差异。总体而言，东部中国的PSC具有较高的可持续绩效和技术水平，而中部和东北中国的PSC可持续性能和技术水平相对较差。基于这些实证结果，本文提出了具体的政策建议，以提高PSC在政府和企业层面的可持续绩效和技术水平。
The power industry is a major source of carbon emissions in China and it is vital, therefore, to address the industry to promote carbon emission reduction. This study takes the power supply chain (PSC) in China, composed of coal-fired thermal power plants and downstream power grid enterprises as its primary research object. From the perspective of sustainable development, the study explores and analyzes the sustainable performance and technology heterogeneity of China’s provinces’ PSCs, proposing the two-system model to evaluate the sustainable performance, generation performance and sale performance of PSCs. In addition, to understand the technology level of PSC, this study applies the meta-frontier technique to analyze the technology heterogeneity of all PSCs across different regions. The proposed models are then applied to analyze the sustainable performance of China’s provincial PSCs. The empirical results demonstrate the market-oriented reform of the power industry in China played a role in promoting the development of power generation enterprises in China’s PSCs but had a limited effect on the power grid enterprises in the PSC. The study also shows that there are significant regional differences in the sustainable performance and technology of China’s PSC. Generally, PSCs in Eastern China have a high level of sustainable performance and technology, while the sustainable performance and technology of the PSCs in Central and Northeast China are relatively poor. Based on these empirical results, specific policy recommendations are presented to improve PSC’s sustainable performance and technology levels at government and enterprise levels.
