自2009年以来，中国的风电经历了爆炸式增长，并重塑了整体能源结构。然而，自二零一零年以来，风电行业投资不断增加，但伴随着持续严重的弃风，导致了显著的效率损失。本文认为，由政治动机驱动的省际市场分割是导致弃风的关键因素。本文首先构建了省际电力市场细分指标。然后将其用作自变量来解释弃风率的变化。采用2009-2016年28个省份的面板数据进行实证分析。结果清楚地表明，市场壁垒积极有助于弃风。具体而言，市场细分指数下降10%将导致弃风限电下降4.3-5.3%。
China's wind power has experienced explosive growth and reshaped the overall energy mix since 2009. However, increasing investment in the wind power industry has been accompanied by persistent and serious wind curtailment since 2010, leading to significant efficiency loss. This paper argues that the interprovincial market segmentation, which is driven by political motivations, is a key factor contributing to wind curtailment. We first construct an interprovincial electricity market segmentation index. This is then used as an independent variable to explain the variation in wind curtailment rates. A panel dataset of 28 provinces during the 2009–2016 period is used for empirical analysis. The results clearly show that market barriers positively contribute to wind power curtailment. Specifically, a 10% decrease in the market segmentation index will lead to a 4.3–5.3% decrease in wind power curtailment.
