Doublestar was founded in 1921 and is headquartered in the West Coast New District of Qingdao City. It owns two listed companies, Kumho of South Korea and Qingdao Doublestar. Qingdao Doublestar (000599) is a state-owned main board listed company. Before 2008, Double Star's main businesses were shoes and clothing. After the comprehensive restructuring of the footwear and apparel industry in 2008, it was separated from the group, and Doublestar fully transitioned to the tire industry. On January 16, 2014, Doublestar started a new journey of "secondary entrepreneurship and creating a world-famous tire brand" with smart transformation as the guide. In 2016, a full-process "Industry 4.0" smart factory for the global tire industry was built, and it took nearly five years to close all old factories and eliminate all backward production capacity. At the same time, it has cultivated two new industries of intelligent equipment and robots, and green ecological recycling, and built an industrial Internet ecosystem of "R&D 4.0" + "Industry 4.0" + "Service 4.0". It has been awarded "Brand Cultivation" and "Technological Innovation" by the Ministry of Industry and Information Technology. "Quality Benchmarking", "Intelligent Manufacturing", "Green Manufacturing", "Green Products", "Green Supply Chain" and "Service Transformation" are pilot demonstration enterprises for the whole industry chain, and are known as "the leader of intelligent tire manufacturing in China". In 2018, Doublestar Holdings ranked among the top ten Korean Kumho Tires in the world. Doublestar tire brand has been ranked among the "Top 500 Asian Brands" for many years in a row. On January 16, 2020, Double Star embarked on a new journey of "Three Entrepreneurships to Create a World-Class Enterprise". On July 16, 2020, Double Star implemented group-level mixed-ownership reform, transforming from a municipal solely state-owned enterprise to a state-controlled mixed-ownership enterprise. At present, Doublestar is focusing on the three main businesses and model innovations of rubber tires, artificial intelligence and high-end equipment, and green ecological recycling, and is implementing the "new four modernizations" strategy of ecologicalization, high-tech, localization, and digital intelligence to transform Doublestar as soon as possible. Create a world-class enterprise that is digitally intelligent, high-tech and sustainable!
