Research on the Linkage Effect of High-tech Industries in China

This paper explored the linkage effects of high-tech industries in China,and the linkage index has been calculated by the input-output model and the data of Chinese high-tech industries. It is concluded that high-tech industries in China have shown stronger backward linkages,which meant that the development of high-tech industries would not only contribute to the positive interaction in their own system,but also help to promote the rapid development of the entire industrial system.
