At present, China's GDP accounts for only 7.3% of the world's, but its steel consumption accounts for 30%, aluminum accounts for 25%, cement accounts for 54%, and fresh water accounts for 15%, ranking first in the world in carbon emissions. These are inevitable for the construction stage, but the contradiction between economic growth and resources, energy and environmental protection is increasingly prominent. The unbalanced economic structure and extensive economic growth mode in the past will be difficult to meet the needs of international competition and sound and rapid domestic development in the post-crisis era. To change this situation, only by strengthening independent innovation, promoting the transformation and upgrading of economic structure and supporting the development of strategic emerging industries can we form new comparative advantages and competitiveness. This is not only related to whether we can seize the historical opportunity of post-crisis development, but also to whether we can consolidate the hard-won situation of economic stabilization and improvement.
