Abstract

New energy storage (NES) is a crucial technology for effectively integrating distributed energy sources and achieving a low-carbon transformation in the power sector. Based on the data of listed industrial enterprises in China from 2013 to 2021, this study examines the effects of the government's NES policy on carbon emissions using a staggered difference-in-differences (DID) method. The results indicate that NES policy significantly promotes the reduction of enterprises' carbon emissions intensity. Our results remain consistent after a series of robustness tests. Heterogeneity analysis shows that the NES policy has a more significant impact on non-state-owned enterprises (non-SOEs), large-sized and medium-sized enterprises, enterprises in low-energy-consuming industries, and enterprises in clean energy-rich areas. Moreover, the mechanism analysis reveals that the proportion of clean energy generation, the capacity for energy storage innovation, and the level of marketization exert positive effects on the relations between NES policy and carbon emission reduction. This study not only contributes to further improving China's NES-related policies, but also provides a useful reference for the formulation and implementation of energy storage policies in other emerging economies.

政府新储能政策对企业碳减排的影响——来自中国的证据

新能源存储是有效整合分布式能源、实现电力行业低碳转型的关键技术。本研究基于2013 - 2021年中国工业上市企业的数据，采用交错差中差（DID）方法检验了政府新能源政策对碳排放的影响。结果表明，新能源政策显著促进了企业碳排放强度的降低。经过一系列稳健性检验，我们的结果保持一致。异质性分析表明，新能源政策对非国有企业、大中型企业、低能耗行业企业和清洁能源富集区企业的影响更为显著。机制分析表明，清洁能源发电比例、储能创新能力和市场化水平对新能源政策与碳减排的关系具有正向影响。本研究不仅有助于进一步完善中国的储能相关政策，也为其他新兴经济体储能政策的制定和实施提供了有益的借鉴。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
