信息技术产业作为同处于快速发展的中国和印度的支柱产业,和国民经济的关系越来越紧密。本文首先通过统计学方法,计算得出两国信息技术产业及子产业对经济增长的实际贡献率:1994年至2007年,中国和印度平均分别为8.16%和6.50%。其次在比较两国信息技术产业及子产业绝对规模、相对规模的基础上,引入迈克尔.波特的“钻石模型”理论分析两国信息技术产业发展存在差别的原因。文章最后对中国信息技术产业及子产业的发展提出了对策建议。 As the pillar industries of China and India, which are in a fast-growing area, the information technology industry is becoming more and more closely linked to the national economy. In this paper, we first calculate the actual contribution rate of the information technology industry and its sub-industries to the economic growth in the two countries through statistical methods. From 1994 to 2007, China and India averaged 8.16% and 6.50% respectively. Secondly, on the basis of comparing the absolute size and relative size of the information technology industry and sub-industry in the two countries, this paper introduces Michael Porter’s “Diamond Model ” theory to analyze the reasons for the differences between the two countries in the development of information technology industry. Finally, the article puts forward countermeasures and suggestions for the development of China’s information technology industry and its sub-industries.
