The production of ceramic products has a long history in China. After long-term development, the manufacturing process has been continuously developed. Especially in the past two decades, the reasonable adjustment of the structure of ceramic products has catered to the consumption needs of consumers at home and abroad, and with the development of society and the improvement of living standards, the application range in life has become wider and wider. Under the cover of the global financial crisis, various domestic industries are generally affected, but the country’s total investment plan of 5 trillion yuan will greatly promote the construction and building materials industry for a long period of time, especially for the building materials industry. Obviously, from the perspective of the industry, the building materials industry has a greater advantage in this financial crisis. At present, the building materials industry is prosperous and the industry concentration is expected to increase in the future. As China's current fixed asset investment still maintains a high level of operation – although the slowdown in investment growth may be real estate investment and industrial investment, the demand for infrastructure construction investment on cement and other building materials is still very obvious.
