The world today is undergoing profound changes unseen in a long time. The science and technology (S&T) are important forces that can drive changes in the pattern of the world. This paper analyzes nine major risks that may affect the development of science and technology in China from three aspects: the new round of scientific and technological revolution and industrial reform, the adjustment of global political and economic pattern, and major sudden public health events. To cope with these risks, we need to pay full attention to the factors of industrialization, scientific and technological innovation, condense the national innovation strategy as a non-Western rising power in the great change situation, as well as strengthen the active risk protection and build a scientific and technological risk prevention network. © ISPM *** right reserved.
