摘要
本文选择湖南省13个地级市2005~2019年的面板数据,采用DPSIR模型评价生态环境安全,以系统聚类法分析各地市生态环境风险水平,运用分位数回归模型对不同分位数水平下生态环境风险影响因素进行了探究,并通过剔除特殊城市法验证了实证结果的稳健性。
This paper selects the panel data of 13 prefecture-level cities in Hunan Province from 2005 to 2019,applies the DPSIR model to evaluate the eco-environmental security levels,uses the systematic clustering method to analyze the eco-environmental risk level of each city.The influencing factors of eco-environmental risks at different quantile levels were explored by quantile regression model,and the robustness of the empirical results was verified by the method of excluding peculiar cities.
