近十年来，随着 经济社会的快速发展， 钢铁产量也迅猛扩张。据 钢铁工业协会和世界钢铁协会的数据显示， 粗钢产量从2006年的4.2亿吨起，经过短短8年就实现了产量翻番，之后在2015年出现短暂下降，降幅为2.3%，这也是自1981年以来 粗钢产量 出现下降。到2016年，受钢材价格反弹、企业生产积极等因素刺激，再度恢复小幅增长，为8.08亿吨，同比增速由2015年的下降2.3%恢复为增长1.2%。同期， 粗钢产量占全球粗钢产量的比重，也由2006年的占三分之一（33.7%），在2013年提升至49.8%，之后一直保持这一高度，2016年比重为49.6%，较2015年提升0.2个百分点。据世界钢铁协会统计，2016年全球粗钢产量为16.285亿吨，同比增长0.8%。（图1）
In the past decade, with the rapid development of China's economy and society, China's steel production has also expanded rapidly. According to the data of China Iron and Steel Industry Association and the world iron and Steel Association, China's crude steel output doubled in just eight years from 420 million tons in 2006, and then decreased briefly by 2.3% in 2015, which is also the first decline in China's crude steel output since 1981. By 2016, stimulated by the rebound in steel prices, positive enterprise production and other factors, it resumed a slight growth again, to 808 million tons, with a year-on-year growth rate of 1.2% from a decrease of 2.3% in 2015. Over the same period, China's crude steel output accounted for one third (33.7%) of the global crude steel output from 2006, increased to 49.8% in 2013, and has maintained this high since then. The proportion in 2016 was 49.6%, an increase of 0.2 percentage points over 2015. According to the statistics of the world iron and Steel Association, the global crude steel output in 2016 was 1.628.5 billion tons, a year-on-year increase of 0.8%. (Figure 1)
