浅析珠三角工业结构与环境污染物的灰色关联

根据2004—2009年珠三角地区各种工业结构、总产值以及工业“三废”排放量等数据，运用灰色关联分析研究了珠三角工业生产规模结构、轻重工业结构、行业结构、工业生产结构与不同环境污染物之间的关联程度。结果表明：珠三角3种生产规模的企业中与工业“三废”关联最大的是中型企业，其次是大型企业，小型企业最小；相对重工业，珠三角轻工业与工业“三废”的关联较大；珠三角工业主导行业与工业“三废”的关联度排序：采矿业〉制造业〉电力燃气及水的生产和供应；就产业结构来说，与污染物的灰色关联度依次是：第一产业、第二产业、第三产业。

Analysis of the Grey Correlation between Industrial Structure and Pollutant Emission in Pearl River Delta

Based on the data of the total value of industrial output and the emission of the three wastes （waste gas, waste water and industrial residue） from 2004 - 2009 of Pearl river delta, Grey correlation degrees of industrial scale structure, light and heavy industry structure, and industrial structures with pollutant emission are analyzed. The results show that medium scale industries have the strongest correlation with the industrial wastes, followed by major industries, and then small scale industries. Light industry has a stronger correlation with the three industrial wastes than heavy industry. Orders of the grey correlation between the leading industry and the three industrial wastes in Pearl River delta are as follows： mining 〉 manufacturing 〉 power gas and water production supply. Orders of the grey correlation degrees between industrial structure and the three industrial wastes are： primary industry, secondary industry and tertiary industry.
