从带动度系数看信息产业在国民经济中的作用

The Role of IT Industry in National Economy From the Viewpoint of Influence Extent Coefficient

该文在 1 997年的中国投入产出表的基础上作适当修改 ,编制出信息产业投入产出表 ,据此建立模型并计算出带动度和带动度系数。通过对信息产业进行研究 ,该文认为信息产业已成为国民经济的第二主导产业 ,对国民经济其他各部门总产品变动的影响很大 。

Based on China's Input Output Table of 1997 with some appropriate modification,the paper first works out the IT Industry Input\|Output Table and then builds models and calculates their influence extent and influence extent coefficient. Through the research on IT industry, the paper holds that IT industry has become the second primary industry of national economy,exerted a great influence on the total production variation of other sectors in national economy, and maintained large room for further development.
