中文摘要：

利用投入产出模型和中国投入产出表（135产品部门）数据实证测算了高技术产业内各行业间以及高技术产业与传统产业之间的产业关联影响程度。结果发现,高技术产业各行业部门无论在高技术产业体系内部还是在整个工业体系内都表现出更强的后向关联性,这意味着高技术产业的发展不仅有助于自身各行业间的良性互动发展,而且有助于带动整个工业行业的快速发展。

英文摘要：

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.
