利用江苏省2005~2012年38个行业的面板数据建立计量模型,对工业废水排放,工业废水中的COD及氨氮排放与工业总产值之间的关系进行了实证研究,结果表明:工业废水、COD及氨氮排放与工业总产值呈同方向变化。不同行业在污染排放方面存在显著差异,其中纺织业,化学原料及化学制品制造业,造纸及纸制品业,电力、热力的生产供应,黑色金属冶炼及压延加工,饮料制造业等是工业废水排放造成水体污染的污染密集型行业。
The econometric model was established by panel data of 38 industries in Jiangsu Province from 2005 to 2012. Empirical studies on the relationship between industrial wastewater discharge, COD and ammonia nitrogen emissions from industrial wastewater and industrial output value were conducted. The results show that industrial wastewater, COD And ammonia emissions and industrial output in the same direction with the change. Different industries have significant differences in pollution discharge. Among them, the textile industry, chemical raw materials and chemical products manufacturing, paper and paper products industry, electricity and heat production and supply, ferrous metal smelting and rolling processing, beverage manufacturing and so on are the industrial wastewater discharge Pollution-intensive industries that cause water pollution.
