摘要
选取1992—2008年北京市主要环境污染物排放量作为北京市的环境污染水平表征指标,以人均GDP表示经济发展水平,通过分析北京市主要环境污染物的排放量与人均GDP之间的关系并建立计量模型,以此探究北京市的经济发展对与环境质量的影响。研究表明,北京市1992—2008年的人均GDP和主要污染物排放量之间的关系可以用EKC曲线进行描述,而且目前的北京部分污染物如工业废水、工业COD、石油类、工业烟尘等的排放量随着人均GDP的增加呈显著下降的趋势,表明现在主要污染物的排放量均已越过拐点,北京市进入经济与环境协调发展的阶段。分析其原因,主要得益于研究时段内北京市产业结构大力调整、环境污染治理投资增加和严格的环境管理政策等多项措施的综合实施。基于过去的经验分析,北京市在发展经济的同时,应该进一步深化调整产业结构,减少工业生产污染物排放并加强环境政策的制定和实施力度,才能保证经济进一步发展的同时使环境得到持续改善。
Taking the discharge amount of main pollutants as the index of environmental pollution level,and with GDP per capita as the index of economic growth,this paper analyzed the relationship between these two indices in Beijing during 1992-2008,and established a computation model to approach the effects of economic growth in Beijing on the environmental quality of the city.The results showed that the environmental Kuznets curve(EKC)could be used for describing the relationship between the GDP per capita and the discharge amount of main pollutants in Beijing during 1992-2008.At present,the discharge amount of the pollutants such as industrial wastes,industrial COD,oils,and industrial dusts,etc.in Beijing had a significant decreasing trend with the growth of GDP per capita,indicating that the discharge of major pollutants in the city had crossed the inflection point,possibly owing to the efficient environmental policy and huge environmental investment by the central and municipal governments.It was suggested that at the time of developing economy,it should be stressed to further adjust industrial structure,reduce industrial pollutants discharge,and strengthen the formulation and implementation of environmental management policies.Only by doing these,the economic growth and environmental quality in Beijing could be cooperatively and sustainably improved.
