As the aging of the population intensifies and public health awareness increases, global demand for innovative drugs continues to grow steadily. Driven by the surge in clinical demand, countries around the world have generally increased their investment in the pharmaceutical field, promoted innovation in new drugs, and accelerated the development process of innovative biologics, which led to an increase in the number of clinical trials and approval for marketing of more original biologics. In 2024, the global original biologics market will reach US$427.9 billion. The market size is expected to reach US$695.5 billion by 2030, with a compound annual growth rate of 8.4% from 2024 to 2030. </pstyle="font-size: 16px; font-family: sans-serif; white-space: normal; word-spacing: 0px; text-transform: none; font-weight: 400; color: rgb (0,0,0); font-style: normal; orphans: 2; widows: 2; margin: 5px0px; letter-spacing: normal; text-indent: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration- style: initial; text-decoration-color: initial">
In recent years, the Chinese government has introduced a series of favorable policies to encourage the development, marketing and commercialization of innovative biologics. Thanks to favorable policies, continuous increase in R&D investment, and remarkable developments in biotechnology, the market size of original Chinese biologics has been rapidly expanding in recent years. In 2024, China's original biologics market will reach RMB 541.8 billion. The market size is expected to reach RMB 1017 billion by 2030, with a CAGR of 11.1% from 2024 to 2030.
