Abstract:
In this chapter, we discuss the technology systems associated with the Chinese biopharmaceutical industry and its development. Upstream biopharmaceutical technology in China has developed quickly. The gap in basic technology and laboratory research and development between China and developed countries is narrowing, with China behind approximately 5 years, while the gap in industrialization and commercialization is approximately 10-15 years wider, and not closing as rapidly.

The technology platform for research and development of protein-engineered drugs has been established in China for some time. This has played a pivotal role in the production of mutant IL-2 and tumor necrosis factor-_. As a result, China has achieved many successes in human genome research, transgenic animal research and industrialization, transgenic plant research, recombinant gene vaccine research. Important technological progress in the near future will be seen in the following: the fermentation technology of active ingredients of Chinese herbal medicines, manufacturing technology innovation of antibiotics, development of novel vaccines and diagnostic reagents, bioengineering manufacturing technology of amino acids, vitamins, organic acids, and steroid hormones, and the development technology of blood substitutes.

Analysis of the top 100 biopharmaceutical enterprises in terms of profits suggests that the total value of output and sales revenues of the Chinese biopharmaceutical industry is increasing faster than those of its other pharmaceutical industries. These indices show more than 15% annual growth for the Chinese biopharmaceutical industry. However, large-scale enterprises share 50% of production and sales, while 66% of Chinese biopharmaceutical enterprises remain small scale, suggesting that the overall scale of Chinese biopharmaceutical enterprises is small and the industrial structure is not well organized.

Large-scale manufacturing technologies adopted at Chinese biopharmaceutical enterprises involve primarily large-scale culture of animal, plant, and microbial cells, and separation and purification engineering of biochemical active substances. Accessory industrial equipment, such as large fermenters, air-compressors, high-speed centrifuges, and crater filter pressing devices can be made in China. However, high-grade bioreactors cannot be manufactured in China. Only medium- and low-grade technology products can be manufactured. In addition, most of these imitate foreign products. This indicates that large-scale production technology at Chinese biopharmaceutical enterprises is still lagging and requires improvement.
