基于DPSIR模型的省域绿色发展绩效评价

Evaluation of provincial green development performance based on DPSIR model

提高绿色发展水平是推动生态文明建设,实现美丽中国的重要途径。将驱动力—压力—状态—影响—响应(DPSIR)模型运用在绿色发展绩效评价中,构建了建设美丽中国愿景下的省域绿色发展绩效评价指标体系,采用层次分析法确定指标权重,采取目标渐进法进行标准化处理,在此基础上构建省域绿色发展绩效综合指数。以贵州省为研究对象,对2009—2019年的绿色发展水平进行评估。结果表明:2009—2019年贵州省绿色发展绩效综合指数呈逐年递增,从Ⅰ级(低)向Ⅲ级(一般)转化的趋势;DPSIR模型中压力层的社会压力、资源消耗、污染排放指标对贵州省绿色发展影响最大;目前贵州省绿色发展处于一般水平(Ⅲ级),下一阶段应重视提升经济发展水平、实施生态环境整治、推进减污降碳、加大民生保障等方面,从而提高贵州省绿色发展水平,最终实现“美丽贵州”。

Improving the level of green development is an important way to promote the construction of ecological civilization and realize beautiful China.The driving force-pressure-state-impact-response(DPSIR)model was used in the evaluation of green development performance to build a provincial green development performance evaluation index system under the vision of building a beautiful China.The analytic hierarchy process was used to calculate the index weights,and the objective asymptotic method was used for data standardization.On this basis,the provincial green development performance comprehensive index was constructed.The green development level from 2009 to 2019 of Guizhou Province was evaluated.The results showed that the green development performance comprehensive index of Guizhou Province from 2009 to 2019 had been increasing yearly,with the trend from LevelⅠ(low)to LevelⅢ(general).The indexes of social pressure,resource consumption,and pollutant emissions of the pressure layer had the greatest impact on the green development of Guizhou Province in the DPSIR model.At present,the green development of Guizhou Province was at a general level(LevelⅢ).Improving the level of economic development,implementing ecological environment remediation,promoting pollution reduction and carbon reduction,and increasing people′s livelihood security should be paid more attention to improve the level of green development in Guizhou Province,and ultimately complete the construction of the Beautiful Guizhou.
