摘    要:基于回归模型分别构建地方环保投资供给能力和需求水平两个评价指标,并计算了我国环保投资供给能力、需求水平及供求水平比的基尼系数,探究了东、中、西部地区环保投资供求水平的空间差异。结果表明,我国环保投资供给能力和需求水平在空间上较为匹配,均呈现东部地区最强、中部地区次之、西部地区最弱的格局,其中,环保投资供给能力在空间分布上均衡性相对较差,基尼系数在0.4左右浮动。我国环保投资供给和需求的变化在时间上相对不同步,"十一五"期间,环保投资供给能力上升速度高于环保投资需求水平;"十二五"期间,环保投资供给能力的上升速度明显跟不上需求水平;"十三五"期间,仅南方部分省份的环保投资供给能力高于环保投资需求水平。

关 键 词:环保投资需求  环保投资供给  基尼系数  均衡性

Abstract:Based on the regression model,this study sets up two evaluation indexes of government environmental protection investment supply capacity and demand level respectively.And we analysis the gini coefficient of supply and demand level and supply-demand ratio of environmental protection investment in China,and explore the spatial difference of supply and demand level of environmental protection investment in China.The results show that the supply capacity and demand level of China’s environmental protection investment are relatively matched in space,which are the strongest in the eastern region,followed by the central region and the weakest in the western region.Among them,the supply capacity of environmental investment is relatively less balanced,and the gini coefficient fluctuates around 0.4.In addition,China’s environmental protection investment changes in supply and demand in time relative to sync.During the 11th Five-Year Plan,environmental protection supply capacity rised faster than the demand level,while the rising velocity supply capacity during the period of 12th Five-Year Plan obviously couldn’t keep up with the level of demand.Therefore,only the southern areas of China’s environmental protection investment supply capacity is above the level of the demand level in the 13th Five-Year Plan.
Keywords:requirement for environmental protection  supply capacity for environmental protection  Gini coefficient  sequilibrium
