摘　　要：通过在IGT方程中引入废物排放率(X),建立了定量分析经济增长与废物排放量之间关系的IeGTX方程与IeGTe方程,并分别给出对应于IeGTX方程与IeGTe方程的废物排放率年下降率的临界值(xk)和单位GDP废物排放量年下降率的临界值(tek);运用IeGTX方程与IeGTe方程分别对工业部门及全国的SO2和COD的排放量(港、澳、台除外)进行了分析.结果表明:2000—2006年工业SO2和COD排放率基本上逐步降低,1997—2008年单位GDP的SO2和COD排放量分别降低了61.72%和71.89%.By introducing the waste emission rate X into the IGT equation, this paper established the I, GTX equation and IoGT, equation for quantitatively analyzing the relationship between economic growth and waste emissions. The critical values of annual decreasing ratio of waste emission rate （expressed as xk ） and annual decreasing ratio of waste emission per unit GDP （ expressed as tek） were given corresponding to the loGTX equation and IoGTo equation, respectively. SO2 and COD emissions （not including the Hongkong, Macao and Taiwan Region） in the industrial sector as well as total SO2 and COD emissions in China were analyzed by the I GTX equation and I GTo equation, respectively. The following results were obtained： emission rates of industrial SO2 and COD emissions in China gradually reduced during the period 2000-2006, and SO2 emissions per unit GDP and COD emissions per unit GDP decreased 61.72% and 71.89% , respectively, from 1997-2008.
