  One of the ways to ensure sustainable development in the construction materials industry is the development and expansion of low Portland cement (PC) content binders production with low energy cost and natural mineral resources and using by-products and wastes of various sectors of the construction industry.The solution of this problem has been successfully implemented by replacing of PC by mineral additives and the development of blended Portland cements.

本文使用2007年CHIP数据,在微观模拟农民工和城镇劳动者反事实部门分布和反事实收入的基础上,对城镇劳动者和农民工的小时收入差距进行了均值分解。为了分析部门进入户籍歧视对收入差距的影响,本文将收入差距来源分为三大类:部门分布规则的差别(部门进入歧视)、部门内收入结构的差别(部门内收入歧视)和人口禀赋差异。最终的分解结果显示,2007年,农民工依然遭受非常显著的收入户籍歧视,但是,部门进入户籍壁垒的效应并不大。具体而言,收入差距中总体户籍歧视的贡献度高达56%,其中,部门内收入歧视贡献了55%,而部门进入
