摘要新一轮电力体制改革逐步放开了发电批发市场，但现行的平均调度模型并不支持新的市场体制。本文以广东省为例，分析了新老火电厂的新进入成本和净收益。我们发现，投产较早的低效率电厂的真实的CONE显著低于新建的高效率电厂。另一方面，低效率发电厂的净收益高于高效率发电厂，这导致了旨在淘汰旧的低效率发电厂的激励措施的扭曲，而新的投资在现有的市场规则下在经济上是合理的。通过模拟市场系统，我们发现，由于容量过剩，高峰电厂的“稀缺收益”被压低，导致所有燃煤电厂亏损。加快市场改革，包括重塑短期经营和长期投资决策的市场机制，是供给侧改革政策成功实施的关键。它们对于确保短期批发市场的经济运作和通过审慎的监管机制确保电力供应的长期充足都很重要。
ABSTRACT The new round of reforms in power system gradually liberalizes the wholesale market for power generation, but the current average dispatch model does not support the new market system. We use Guangdong Province as a case study to analyze the cost of new entry (CONE) and net revenue of new and old coal power plants. We find that the real CONE of low-efficiency plants that were put into production earlier is significantly lower than that of the new high-efficiency plants. Meanwhile, the fact that net revenues are higher for low-efficiency plants than high-efficiency plants has led to distortion in the incentives aimed at retiring old low-efficiency plants from the market, and new investment is economically justified under existing market rules. By simulating a market system, we find that the “scarce returns” of peak plants are depressed because of excessive capacity, which leads to losses from all coal power plants. Accelerating market reforms, including reshaping the market mechanism of short-term operations and long-term investment decision-making is key to the successful implementation of supply-side reform policies. They are important for ensuring both economic operations in the short-run wholesale market and the long-term sufficiency of the power supply via careful regulatory mechanisms.
