安徽省产业结构演变的生态环境效应

Analysis on the Eco-Environmental Effect of Industrial Structure Evolution in Anhui Province

基于产业结构熵值、工业结构特征偏向指数等方法,利用安徽省2006—2016年相关数据,对安徽省产业结构演变的环境效应进行了分析。结果表明:①随着安徽省产业结构熵值的变小,三大产业结构内部各产业间的协同性不断提高,结构比也渐趋合理,对生态环境带来的正向影响效应逐步显现。②2006—2011年,安徽省产业结构的合理化和高级化程度皆不高,导致其产业优化升级指数呈现下降趋势,产业结构演变的环境正效应并未体现,2011年以来,随着产业结构优化升级的速度逐渐加快,安徽省生态环境质量明显得到提升。③2006—2016年,安徽省四大工业污染物排放强度呈现不同程度的下降,其中工业SO2和工业固废排放ICB值下降较为明显。随着工业污染排放水平的降低,生态环境质量有所提升,但提升速率较慢。工业结构内部行业中,煤炭开采与洗选业、化学原料和化学制品制造业等八大行业工业污染排放相对较大。

Based on industrial structure entropy and industrial structure characteristic bias,by using relevant data of Anhui Province from 2006 to 2016,the environmental effect of industrial structure evolution is analyzed in Anhui Province.The results show that:1)With the decrease of the industrial structure entropy in Anhui Province,the synergy among the three industries has been continuously improved,and the structure ratio has become more reasonable,and the positive impact on the eco-environment has gradually emerged;2)From 2006 to 2011,rationalization and upgrading of industrial structure is not high in Anhui Province.As a result,the index of industrial optimization and upgrading shows a downward trend in Anhui Province,and the environmental positive effect of industrial structure evolution is not reflected,since 2011,with the acceleration of industrial structure optimization and upgrading,the quality of eco-environment has been significantly improved in Anhui Province;3)From 2006 to 2016,the emission intensity of the four major industrial pollutants has decreased in varying degrees in Anhui Province,among which the ICB value of industrial SO2 and industrial solid waste emissions have decreased significantly.With the reduction of industrial pollution emission level,the eco-environment quality has been improved,but the rate of improvement is slow.Within the industrial structure,eight industries,including coal mining and washing industry,chemical raw materials and chemical products manufacturing industry,have relatively large Industrial pollution discharge.
