根据我国工业增加值率对工业增加值的弹性测算,结果显示我国工业增加值率随着工业增加值的增长而下降。部分学者认为我国工业增加值率下降的原因是工业经济效率的下降。而从统计方法的角度分析,工业经济效率下降只是工业增加值率下降的充分条件而非必要条件,工业增加值率对经济效率的衡量效果受到影响,工业增加值率并不必然反映经济效率。
According to the ratio of value added to gross industrial output value of the elastic calculation,results showed that the Ratio of value added to gross industrial output value decline with the growth of value added to gross industrial output value.Some scholars believe that the decline of economic efficiency is the ratio of value added to gross industrial output value for the decline.From the statistical methods of analysis,the decline in the economic efficiency is the sufficient condition of the reduction of the ratio of value added to gross industrial output value,not the necessary condition,therefore,as a measurement of the economic efficiency,the effect of the ratio of value added to gross industrial output value will be affected.
