This study employs a recursive dynamic computable general equilibrium model to evaluate the consequences of renewable energy (RE) expansion policies in South Korea, focusing on their impact on the economy, income distribution, and air pollution reduction. It assumes a scenario in which RE generation constitutes 20% of the total electricity generation by 2030. Various scenarios are explored, including those with and without emission regulations and those considering increased productivity of RE technology. Key findings suggest that expanding RE policies stimulates labor demand and revitalizes upstream industries. However, its effectiveness depends on increasing the efficiency of RE technologies. Carbon regulation, such as emissions trading schemes, reduces greenhouse gases and air pollutants, with environmental benefits outweighing GDP reductions. It decreases income inequality, whereas policies to promote RE exacerbate it, requiring corrective measures. Nevertheless, productivity improvements in the RE sector enhance income distribution.

可再生能源扩张政策对经济、收入分配和减少空气污染的影响

本研究采用递归动态可计算一般均衡模型来评估韩国可再生能源 (RE) 扩张政策的后果，重点关注其对经济、收入分配和减少空气污染的影响。它假设到 2030 年可再生能源发电占总发电量的 20%。探讨了各种情景，包括有或没有排放法规的情景以及考虑提高可再生能源技术生产力的情景。主要研究结果表明，扩大可再生能源政策可以刺激劳动力需求并振兴上游产业。然而，其有效性取决于可再生能源技术效率的提高。排放交易计划等碳监管可以减少温室气体和空气污染物，其环境效益超过GDP减少量。它减少了收入不平等，而促进可再生能源的政策则加剧了收入不平等，需要采取纠正措施。然而，可再生能源行业生产率的提高改善了收入分配。
