基于熵值-主成分分析的环境治理公众参与水平评价研究

Evaluation of Public Participation Level in Environmental Governance Based on Entropy and Principal Component Analysis

文章运用主成分分析法与熵值法相结合的方法,以公众参与环境治理的各个途径为数据依据,先通过数学变换和降维得到新的指标并算出分值,再通过熵值法赋权,对31个省市的公众参与水平进行评价。结果表明,华东地区公众参与水平最高,后依次是中南、西南、东北和华北地区。以此结果为基础提出制定个性化环保政策、提升政府环境治理能力和提升公众环保意识3条建议。

In this paper,the method of combining principal component analysis with entropy was used.The data were based on the public participation in various approaches for environmental governance.First,new indicators were constructed through the mathematical transformation and dimensionality reduction,and the scores were obtained.Then,the entropy method was used to assign weights.Hence,the level of public participation in 31 provinces and cities was evaluated.The results showed that the level of public participation in East China was the highest,followed by the Central South,Southwest,Northeast and North China.Based on the result,three suggestions were proposed including formulating the personalized environmental protection policies and improving the government environmental governance capacity as well as improving the public environmental awareness.
