基于供需模型的全面小康社会环境质量供需状态研究

Study of Supply and Demand Levels of Environmental Quality in a Comprehensive Well-off Society Based on EAS- EAD Model

基于SAD-SAS模型,结合2005~2014年我国环境质量供需指标,分析了2005-2014年我国的环境质量供需水平。研究表明,近10年间,我国环境质量供给水平得到大幅提升,并在2014年总供给数值达到最大值（0.66）。同时我国2005~2014年之间的环境需求也处于急剧上升的趋势,表明我国短期内还难以达到满足期待的环境质量水平。

In this paper, on the basis of SAD-SAS model, with regard to the supply and demand indicators of environmental quality in China from 2005 to 2014, the supply and demand levels of environmental quality in China from 2005 to 2014 are analyzed. The results show that the supply level of environmental quality in China has been improved substantially in the recent 10 years, with the total supply value reaching to the maximal（0.66） in 2014. At the same time, the environmental demands from 2005 to 2014 have risen sharply, indicating that it is difficult to meet the desired environmental quality level in China in a short time.
