我国钢制品消费结构对其平均使用寿命的影响效应分析
Effect analysis of consumption structure of steel products on its average service life in China
摘要
Abstract
Based on China 's downstream steel industrial steel consumption quantity and service life during 2013 and 2015, the average life of the steel products in China was analyzed through logarithmic mean Divisia index method. The results showed that the average service life of the steel products in China is 22. 27, 22. 24 and 22. 1 years respectively from 2013 to 2015, showing a declining trend year by year. In the consumption structure, other civil engineering besides energy, transportation and housing construction and railway industry are in the top two ranks. They are 163%and -155% respectively. Effect of the appliance industry is the smallest, only -3%. The positive values indicate a promotion effect on the decline of the average service life of the steel products, while the negative values show an inhibition effect. Changes in the consumption structure indirectly led to a loss of 5. 08 million tons of steel, being about 0. 74% of the major steel consumption in 2013.关键词
