广州市工业结构与环境污染物的灰色关联分析

Analysis of the Gray Relationship between Industrial Structure and Environmental Quality in Guangzhou City

文章根据2003年-2007年广州市各种工业结构企业工业总产值以及工业三废排放量等数据,运用灰色关联分析方法研究了广州市工业生产规模结构、轻重工业结构、行业结构与环境污染物之间的关联程度。结果表明:①广州市三种生产规模的企业中与工业三废关联最大的是小型企业,其次是中型企业,大型企业最小;②相对重工业,广州市轻工业与工业三废的关联较大;③广州工业主导行业与工业三废的关联度排序:纺织业>石化工业>电子产品制造业>食品工业>机械制造工业>冶金工业>电力燃气及水的生产供应业。

According to data from the total value of industrial output and the discharge amount of the ＂three industrial wastes＂ （waste gas, waste water and industrial residue）from 2003 -2007 in various industrial structures of Guangzhou, this article, by means of gray correlation, analyzed the different degrees to which industrial scale structure, light and heavy industry structure, and trade structure correlate with pollutant discharge. It turns out that small enterprises have the most serious effect on the industrial wastes, followed by medium - sized enterprises, large one least ; besides,light industry links closer with the three industrial wastes than heavy industry; Finally, orders of the grey correlation between the leading enterprises and the three industrial wastes in Guangzhou are as follows：Textile Industry 〉 Petrochemical Industry 〉 Electronics Industry 〉 Food Industry 〉 Machinery Manufacturing Industrial 〉 Metallurgy Industry 〉 Power fuel and water supply industry.
