简介：一年一度的“两会”于3月3日正式召开，中国经济成为世界关注的焦点。观察中国经济，从外部看，世界经济增长乏力、外需下降，出口拉动作用减弱；从内部看，要素成本上升，投资对经济推动的效率亟待提升。在这种情况下，中国政府大力推动供给侧结构性改革，是形势使然，大势所趋。

简介：中国物流业发展正在进入一个关键阶段。从各项关键指标来看，中国已经是私副其实的物流大国，但是随着经济发展速度降下来，物流业也告别了高速增长阶段，进入转型发展新时期。一边是发展速度减缓，一边是成本效率改善压力加大，物流业如何从供给侧结构性改革中获得发展的新动能？

简介：中国供给侧结构性改革大大改善了国内钢铁市场环境,并增加了中国对铁矿石海运进口的依赖,但未来进口仍面临着不确定因素。为了化解国内钢铁行业产能严重过剩的状况,2016年初中国开始实施＂供给侧结构性改革＂。根据《钢铁工业调整升级规划（2016-2020年）》,中国计划在2020年之前关停钢铁产能1.5亿吨。
