受全球经济回暖缓慢和我国经济增速放缓影响，国内工程机械的销量已经连续4年出现下滑，但今年上半年下滑幅度进一步加大；而钢材作为工程机械最重要的原材料，每年消费各个品种的钢材达几百甚至上千万吨。

　　Affected by the global economic recovery is slow and the impact of China's economic slowdown, the domestic sales of construction machinery has been 4 consecutive years of decline in the first half of this year, but the decline was further increased; while the steel raw material as the most important construction machinery, the annual consumption of various types of steel hundreds or even thousands of tons.

　　虽然国内经济增速放缓，但稳增长的项目交通基础设施建设、城市地下管道建设、水利基础设施建设、一带一路”、京津冀一体化、长江经济带等投资项目在逐步推进，使得工程机械销售有望好转，为工程机械用钢提供支持。

　　Although the domestic economic slowdown, but the steady growth of the traffic infrastructure construction, city underground pipeline construction, water conservancy infrastructure construction, Belt and Road Initiative, Beijing Tianjin Hebei integration, the Yangtze River economic belt and other investment projects in the step by step, the construction machinery sales is expected to be good, for the engineering machinery steel support.

　　一、上半年国内工程机械销量同环比下滑明显

　　First half of the domestic construction machinery sales fell significantly with the chain

　　据中国工程机械工业协会统计，1-6月中国装载机、液压挖掘机、汽车起重机及压路机的销量分别为4.27万台、3.55万台、0.56万台及0.59万台较2014年同比增长-53.85%、-42.07%、-34.83%及-28.96%。就上半年数据来看，今年工厂机械增速下降最多的月份在2月份和6月份，其中2月份和6月份的下降幅度分别为65.55%、61%、38.56%、72.22%和61.94%、26%、39。26%、35.6%。

　　According to the Chinese Engineering Machinery Industry Association statistics, 1-6 month China loader, hydraulic excavator, crane and roller sales were 42 thousand and 700 units, 35 thousand and 500 units, 5 thousand and 600 units and 5 thousand and 900 units in 2014 compared with an increase of -53.85%, -42.07%, -34.83% and -28.96%. On the first half of the data, this year, the largest decline in the growth rate of machinery factory in February and in June, which in the year of June and in the fall of 65.55%, respectively, 61%, 72.22%, and 61.94%, 26%, and 39, respectively, in the year of February. 26%, 35.6%.
