黄河流域高质量绿色发展水平与空间格局演化特征

运用DPSIR模型及空间计量方法对黄河流域高质量绿色发展水平及时空演化进行测度和研究。结果表明：（1）黄河流域高质量绿色发展水平呈现稳步提高的趋势，但整体处于初级阶段，1999—2019年年均增长3.32%，内部驱动力和响应方面贡献显著，压力、状态和影响方面发展有待提高。（2）流域内各省区高质量绿色发展水平差异显著，且均呈增长趋势。（3）黄河流域高质量绿色发展水平存在空间自相关，但这一相关性逐渐减弱，并没有形成具有沿黄分布的空间集聚特征。黄河流域高质量绿色发展的空间集聚中心由四川省（1999年）转移到内蒙古自治区（2019年），尚未形成一定规模的空间集聚群。

Spatial pattern evolution characteristics of high-quality green development level in the Yellow River Basin

The DPSIR model and spatial econometric method are used to measure and study the temporal and spatial evolution of high-quality green development in the Yellow River Basin. The results show that： （1） The level of high-quality green development in the Yellow River Basin shows a steady improvement trend， but the whole is in the primary stage. During the past 20 years， it has steadily increased at an average annual rate of 3.32%， and the internal driving force and response have contributed significantly. The development of pressure， state and impact needs to be improved. （2） There are significant differences in the level of high-quality green development among provinces along the Yellow River， but the high-quality green development level of each province shows an increasing trend. （3） There is spatial autocorrelation in the level of high-quality green development in the Yellow River Basin， but this correlation is gradually weakening， and there is no spatial agglomeration characteristic with distribution along the Yellow River. The spatial agglomeration center of high-quality green development in the Yellow River Basin has shifted from Sichuan Province （1999） to Inner Mongolia Autonomous Region （2019）， and has not yet formed a spatial agglomeration group of a certain scale.
