Metal processing machine tool consumption from 2011 to reach the maximum after 2015 to experience three steps of decline. The first step is the relative high of 2011 to 2012, respectively 390.9 and 38.28 billion US dollars; the second step is 2013 to 2014 a significant decline, respectively, 319.1 and 318.3 billion; the third step is 2015 Of machine tool consumption in 2015 was 27.5 billion US dollars in the first half of 2016 is 12.9 billion US dollars, down 9.2%. Metal processing machine tool production trends and consumption changes in roughly the same, but also the basic formation and consumption of three step-down synchronization. The first half of 2016 metalworking machine tool production 10.4 billion US dollars, down 8.8%. Although the metal processing machine tool imports also showed a decline, but the third step is not obvious, mainly due to the gradual decline in imports in the late slow down. The first half of 2016, metal processing machine tool imports 4 billion US dollars, down 6.1%.
