In this paper, we analyze the role of economic policy in prompting energy efficiency. This study reviews three aspects, theoretical, empirical, and existing policies to evaluate the relationship of energy efficiency and economic policy. This study furthermore identifies the existing issues from a policy perspective in energy efficiency. Although not all public policies may be justified, it suggests that these types of financial incentives, particularly those based on economic instruments, can play a crucial role in advancing energy efficiency. Additionally, this study identifies existing issues in energy efficiency target achievement and proposes solutions based on the literature review. Finally, it provides possible future research pathways from the aspect of economic policy tools in energy efficiency.
