在对广东省工业“三废”EKC曲线进行验证的基础上,运用Kaya恒等式把工业“三废”排放的影响因素分解为清洁生产技术水平、工业GDP单位能耗、工业经济发展水平和工业人口规模四个维度,并用LMDI分解法分析各因素的作用机制。研究结果显示:工业废水与废固符合三次多项式的EKC曲线拟合特征,工业废气与经济发展水平之间呈单调递增关系;清洁生产技术水平和工业GDP单位能耗对污染物排放具有负向抑制作用,工业经济发展水平和工业人口规模则对污染物排放具有正向促进作用。
Based on the verification of the industrial “three wastes” EKC curve in Guangdong Province, the factors affecting the industrial “three wastes” emission were decomposed into the clean production technology level, the unit GDP of industrial GDP, the level of industrial economic development, and the Kaya identity. The industrial population scale is four dimensions, and LMDI decomposition method is used to analyze the mechanism of each factor. The results show that the industrial wastewater and waste solids conform to the cubic polynomial EKC curve fitting characteristics, and the monotonically increasing relationship between industrial waste gas and economic development level; the clean production technology level and the unit energy consumption of industrial GDP have negative inhibition on pollutant discharge. The role of the industrial economy and the size of the industrial population have a positive effect on the emission of pollutants.
