Promoting energy efficiency optimization and upgrading the energy structure is a crucial pathway for energy companies to achieve a green and low-carbon transformation. This paper first constructs an endogenous growth E-DSGE model to analyze the impact of environmental regulation policy on energy efficiency optimization and carbon reduction. It further investigates the role of targeted monetary policy in advancing energy structure upgrade and estimates the optimal regulatory policy mix for carbon reduction transformation. The findings indicate that while environmental regulation policy can enhance energy efficiency, their effects are limited and may not support expanded production. Targeted monetary policy, however, can gradually upgrade energy structures while ensuring energy supply. The optimal combination of macroeconomic control policies can enhance social welfare and promote the green and low-carbon transformation of energy firms. Policy recommendations include formulating a comprehensive macroeconomic strategy, utilizing environmental regulations to promote energy efficiency, and employing targeted monetary policy to advance energy infrastructure upgrades. By coordinating fiscal, monetary, and environmental policies, the green and low-carbon transformation of energy firms can be effectively supported.

宏观政策会促进能源企业绿色低碳转型吗？


推动能效优化、能源结构升级是能源企业实现绿色低碳转型的重要路径。本文首先构建了内生增长 E-DSGE 模型，分析了环境规制政策对能效优化和减碳的影响。进一步考察了定向货币政策在推进能源结构升级中的作用，并估计了减碳转型的最优监管政策组合。研究结果表明，虽然环境监管政策可以提高能源效率，但其效果有限，可能无法支持扩大生产。然而，有针对性的货币政策可以在保证能源供应的同时逐步升级能源结构。宏观调控政策的最佳组合可以提高社会福利水平，促进能源企业绿色低碳转型。政策建议包括制定全面的宏观经济战略，利用环境法规提高能源效率，以及采用有针对性的货币政策来推进能源基础设施升级。通过协调财政、货币和环境政策，可以有效支持能源公司的绿色低碳转型。
