中文摘要：

文章以江苏省2000-2012年信息产业和经济发展的面板数据为研究对象,运用ADF单位根检验和格兰杰因果关系模型检验出江苏省信息产业和经济增长的关系是互为因果关系;进一步借鉴菲德模型评估江苏省信息产业对经济增长的直接效应和溢出效应,结果显示：江苏省信息产业对经济增长以及对非信息产业产生的外溢效用都不是很显著,但信息产业的边际生产力远远高于非信息产业。

英文摘要：

The paper,by taking the panel data of information industry and economic development in Jiangsu Province during the year of 2000 to 2012 for the study and applying ADF unit root test and Grainger causality model test, draws that the rela-tionship between information industry and economic growth is mutually causal in the province. The paper also makes further as-sessment of the direct effects and spillover effects of information industry on economic growth by using Feder model. The results show that the impacts of information industry on both economic growth and the spillover effect of non-information industry are not very significant in Jiangsu Province,but the marginal productivity of information industry sector is much higher than that of non-information industry departments.
