循环经济与节能减排政策对我国环境压力影响的研究

该文基于表征人类活动对环境影响的IPAT方程,运用结构分解分析模型,采用修正后的Laspeyres方法,选取污染物排放量和资源消耗量作为衡量环境压力的指标,构建了分析循环经济与节能减排政策对我国环境压力影响的方法。对2000—2009年我国环境压力的时序变化及其影响因素进行了分析,结果表明:研究期间,人口因素对环境压力变化的影响较小且比较稳定,经济增长因素对环境压力增大具有明显的正向效应,循环经济与节能减排政策因素则相对表现出抑制效应。政策因素对环境压力的减缓程度视不同类型污染而有所差异。在资源消耗方面,政策因素的抑制效应在"十一五"期间比"十五"期间更为明显,且对用水总量增长的抑制作用比能源更显著。

Impact of circular economic,energy-saving and emission-reduction policies on environmental pressure in China

The IPAT equation was used to build a function to describe the environmental pressure represented by pollutant discharge and resource consumption.The relationships between China’s environmental pressures and various driving factors in 2000—2009 were then analyzed using a structural decomposition analysis(SDA) model combined with the refined Laspeyres method.In this study period,population had little effect on increasing the environmental pressure,while economic growth greatly influenced the environment.Circular economic,energy-saving and emission-reduction policies mitigated the environmental pressure with the impacts differing depending on the pollutant type.The policy factor had a more significant effect on the reduction of the growth of water consumption than energy consumption.The mitigation effect was more remarkable in the "Eleventh Five-Year" period than in the "Tenth Five-Year" period.
