摘要
通过构建黄河流域地级市绿色化测量评价指标体系,对该流域2007-2018年96个地级市的绿色化水平进行测度,并验证资源依赖对黄河流域绿色化水平具有显著的非线性影响。结果发现:(1)黄河流域绿色化水平整体呈上升态势,区域间差异明显,且自2013年以来差距有缩小的迹象。(2)区域绿色化水平全局空间呈现出正向集聚态势,但局部具有"中心离散,周围集聚"的特征,区域绿色化水平不均衡程度在逐渐增加。(3)资源依赖对黄河流域具有显著的双门槛效应,其在不同门槛范围作用大小和方向均有着显著的差异。(4)经济增长、环境质量、政府支持、市场驱动和产业结构是区域绿色化的5个主要影响因素。
Based on the panel data of 96 cities in the Yellow River Valley from 2007 to 2018,this paper reconstructed the evaluation index system of greenization,and verified that the resource dependence had significant non-linear effects on of greenization in the Yellow River Valley.The results showed that:(1)The index had gradually increased,but the inter-difference was obvious and the regional gap had been gradually narrowing since 2013.(2)There was a global spatial agglomeration distribution pattern among cities.However,the local area presented"discrete center,cluster around",the local spatial distribution was uneven and the differentiation had gradually increased.(3)The analysis found that the resource dependence had significant double-threshold effects on greenization.(4)The main factors affecting the greenization of the Yellow River Valley were economic growth,environmental quality,government support,market openness and industrial structure.
