英文摘要：

Seasonal power price (SPP) and differentiated power rationing (DPR) are two solutions for tackling power shortages as they adjust power allocation, alleviate power supply–demand contradictions, and promote the sustainable development of the energy industry. Based on microdata from 9593 industrial enterprises in China, this study analyzes the effects of SPP and DPR on allocating power resources optimally. The results reveal the following. (1) Under SPP, the price of power fluctuates in summer between 0.4627 and 0.5047 yuan/kWh, while spring-autumn and winter prices remain stable at 0.3785 yuan/kWh and 0.4627 yuan/kWh, respectively. (2) Under DPR, according to industrial efficiency and the optimal enterprise power rationing ratio, power rationing solutions can be summarized into forced, moderate, and incentive types. (3) SPP and DPR can effectively alleviate power shortages. However, SPP is superior in maintaining balanced industrial development and reducing power costs by guiding enterprises toward off-peak production through price adjustment mechanisms. Finally, policy implications are illustrated in implementing SPP and DPR in the case of power shortages.

中文摘要：

季节性电价（SPP） 与差异化限电（DPR）是应对电力短缺的两大方案，其能够调整电力资源配置，缓解电力供需矛盾，推动能源产业的可持续发展。基于中国9593家工业企业的微观数据，本文分析了SPP和DPR对优化电力资源配置的效果。结果表明：（1）SPP下，夏季的电价在0.4627—0.5047元/千瓦时之间浮动，春-秋季节的电价和冬季的电价分别稳定在0.3785元/千瓦时和0.4627元/千瓦时。（2）DPR下，按产业效率和企业最优限电比例，限电方案可归纳为倒逼型、温和性和激励型。（3）SPP和DPR均能有效缓解电力短缺问题。然而，SPP能利用价格的调节机制引导企业错峰生产，在维持产业均衡发展、降低企业用电成本上更具优势。最后，阐述了在电力短缺情况下实施SPP和DPR的政策启示。
