基于词频计算原理的环境政策分析与评价

Analysis and Evaluation of Environmental Policy Based on WordScore Theory

环境政策是政府处理环境问题的直接体现,对环境政策文本的分析可以解读现行政策。从信息分析的角度出发,采用词频计算方法,以全国人大颁布的环境类法律为参考样本,针对沪、渝、津环境政策以及江、浙、沪水污染政策,进行横向及纵向的定量分析,比较中央与地方、各地方之间环境政策的异同。研究发现地方环境政策与中央环境政策一致、地方环境政策之间"大同小异",认为中央和地方政府因地制宜,采取了最符合各自实际情况的环境政策。

Environmental policy reflects directly how governments deal with environmental problems. By analyzing environmental policy texts we can interpret prevailing policy. From the angle of information analysis, this article takes WordScore as a kind of policy compu- ting method and takes environmental policies published by NPC as reference texts. The paper makes a transversely and longitudinally quantitative analysis and comparison to Shanghai, Chongqing, Tianjin＇s environmental policies and Jiangsu, Zhejiang, Shanghai＇s wa- ter pollution policies. This paper finds that local and central governments had similar environmental policies, and policies between local governments are largely identical but with minor differences. It gives a conclusion that both central and local governments had made the suitable policies according to its own situations.
