Adhere to the advanced nature of technology, orderly and rational use of foreign capital, together with domestic enterprises to become the two wheels of the development of the rubber industry.

Foreign companies are optimistic about China's tire market, and have come to China to set up factories, starting from joint ventures, cheap acquisitions, and then wholly-owned factories. The top 10 global multinational tire companies all entered China, and other foreign companies also flocked to Michelin. 23 foreign companies such as Bridgestone, Goodyear, Hankook and Jiatong have used more than 40 radial tire companies in China through the preferential policies of foreign investment in China. Foreign-funded enterprises mainly use Chinese equipment and Chinese raw materials, starting from the production of low-end products, and gradually upgrading with new technologies and new products to expand their market competitiveness. Their passenger semi-steel radial tires and all-steel radial tires rely on large companies. The advantages of big brands and new cars, the proportion of products once accounted for 65% and 30% of the national total.

The tire industry is dominated by state-owned, state-owned and large private enterprises, forming a leading position with foreign-funded enterprises, promoting each other in competition and competing for development. In 1985, the total output of tires nationwide was 19.25 million. The first radial tires appeared in the tire production statistics, with an annual output of 280,000. In 1990, the total tire output was 28.16 million, and the radial tire output was 1.18 million. In 1995, the tires. The total output was 55.71 million, and the number of radial tires was 6.89 million. In 2000, the total output of tires was 109 million, which exceeded 100 million for the first time. The number of radial tires was 36 million, and the rate of meridian was 33%. In the year, the total output of China's tires reached 250 million, of which 141 million radial tires, the rate of meridian was 59.2%, the total tire output exceeded the United States, ranking first in the world; in 2015, the total tire output was 565 million, meridian The output of tires reached 511 million, and the meridian rate reached the international advanced level of 91.2%. The introduction of technical equipment, digestion and absorption and localization, wrote a glorious chapter in the history of the development of the rubber industry.

Other rubber-based products, mainly based on independent research and development, combined with the introduction of equipment, vigorously implement technological transformation, product upgrades continue to advance.

As a necessity to improve people's lives, rubber shoes are also the first products to be upgraded and upgraded. The market has replaced new energy-saving, consumption-reducing, beautiful and practical new products such as sports shoes, casual shoes, sneakers and wedge women's shoes. Traditional liberation shoes are developing towards medium and high-end products. The old enterprise, the old famous brand Qingdao Double Star, took the lead in the factory “going up the mountain to the countryside”; the original post-owned enterprise formed the Jihua Group, and implemented intensive management; the glory of Zhejiang Ruian, the humanity, the peak of Sichuan and Chongqing, Qiangbu, Henan Feihe, Fuda and other private enterprises have risen from the group, and the five major sectors account for about 80% of the national rubber shoe production and export. Fujian Jinjiang, Shandong Dongying and other places have formed a joint venture group, with cold-adhesive craft shoes, to undertake the major transfer of international big-name shoe companies, well-known brand products. Shanghai's “Puerback” sneakers, the return of this nearly 100-year-old brand, are active in domestic and foreign markets and become the new favorite. China's rubber shoes industry is one of the new features. In 1985, the national rubber shoe production reached 687 million pairs. In 1990, it reached 888 million pairs. Although it has been fluctuating since then, it has been stable at more than 1 billion pairs, and its production and export volume rank first in the world. .
