Since the 21st century,the international competitiveness of China's machinery industry has improved rapidly,and in scale China has become the first in the world,but in some competitiveness indicators there is still a big gap compared with developed countries. A country's industry competitiveness reflects its position of division of labor in the global industrial chain. Changes in the pattern of international division of labor,the domestic and international market demand,the supply of factors and price,and government policies,will have a profound impact on industry competitiveness changes. After 2008,some conditions of promoting rapid upgrading of China's machinery industry competitiveness over the past ten years have changed,but at the same time,because China has basically finished the middle stage of industrialization,the power and ability of upgrading machinery industry structure have been enhanced,and the goverment gives an unprecedented support for advanced equipment manufacturing,all these make China machinery industry have certain conditions to rely on technological progress to promote upgrading competitiveness. <<
