摘要

本研究采用差异中的差异方法来调查中国县域风电发展对草原质量的影响。我们发现强有力的证据表明，将风电容量密度增加0.02兆瓦/平方公里会导致归一化差异植被指数比其平均值降低0.5%。不包括经济活动作为传输通道，异质性效应表明，生长季节夜间时间较短的高纬度地区受负外部性的影响较小，支持小气候效应作为主要机制。此外，稀缺的风资源和丰富的降水可能会减弱负面影响。

Evaluating the External Effect of Wind Power Development on Grassland Quality

This study uses a difference-in-differences approach to investigate the effect of county wind power development on grassland quality in China. We find robust evidence that increasing wind power capacity density by 0.02 megawatt/km2 leads to a 0.5% reduction in the normalized difference vegetation index from its mean value. Excluding economic activities as a transmission channel, heterogeneous effects suggest that higher latitude areas with shorter night hours in the growing season are less affected by the negative externality, supporting microclimate effects as the main mechanism. In addition, scarce wind resources and abundant precipitation may weaken the negative effect.

期刊介绍： Land Economics is dedicated to the study of land use, natural resources, public utilities, housing, and urban land issues. Established in 1925 by the renowned economist and founder of the American Economic Association, Richard T. Ely at the University of Wisconsin, Land Economics has consistently published innovative, conceptual, and empirical research of direct relevance to economists. Each issue brings the latest results in international applied research on such topics as transportation, energy, urban and rural land use, housing, environmental quality, public utilities, and natural resources.
