In recent years, with the rapid development of China's auto industry, China's tire industry has developed rapidly. At present, China has become the world's largest tire producer. According to the “2010-2015 China Tire Industry Investment Analysis and Prospect Forecast Report†released by the China Investment Advisor, it shows that China’s tire production was 133.56 million in 2001; China’s tire production was 160 million in 2002; and China’s tire production was 18,700 in 2003. Million; 2004 tire production in China was 239.26 million; in 2005 China's tire production was 31.8 million; in 2006 China's tire production was 43.19 million; in 2007 China's tire production was 55.49 million; in 2008 China's tire production was 54615 Ten million; China's tire production in 2009 was 654.64 million. Zhong Jianzhi, a researcher in the chemical industry of China Investment Advisors, pointed out that at present, the development of the tire industry in China is still driven by domestic demand, exports, and investment. Among them, exports account for about 40% of domestic tire production, and domestic tires are for international use. The market is more dependent. At present, due to the lack of optimism in the export situation and the continuous increase in domestic production capacity, overcapacity in the tire industry in China has emerged. On the one hand, affected by the international financial crisis, Other countries in the world, in order to protect the development of the tire industry in China, have frequently implemented trade protection policies on tires in China, which has affected the export of tires in China. On the other hand, as we see the current prosperity of China's auto market, some domestic tire manufacturing companies are expanding their production on a large scale, or launching new tire projects, which will further increase the production capacity of China's tires. According to the "2010-2015 China Tire Industry Investment Analysis and Prospect Forecast Report" released by China Investment Advisor, 2009, Jinyu Tire Co., Ltd. has an annual output of 10.5 million sets of semi-steel radial tires project has been partially put into production; Double Star Group launched an annual output 1 million sets of all-steel radial tire projects; Shandong Linglong has an annual output of 12 million sets of high-performance passenger car radial tires and other five construction projects have also started. Therefore, Chang Yongzhi believes that with the continuous increase in international trade friction and the expansion of tire companies, China's tire industry has faced the issue of excess capacity.
