基于改进的RITE 模型选取15 个指标，计算了1998-2005 年间东北老工业基地与全国的信息化指数；对比 了东北老工业基地与全国平均信息化进程发展差异； 并利用Pearson 相关分析法探讨了东北老工业基地信息化水 平各影响因子对区域整体信息化水平的贡献差异。结果表明：与全国平均水平相比，东北老工业基地整体信息化水 平较高，年均高出全国平均水平8.40%；但就区域内部而言，地区之间发展不平衡，其信息化水平强弱依次为辽宁 省> 吉林省> 黑龙江省；对于信息化测度指标，信息装备率(r²=0.991) 和通信主体水平(r²=0.981) 是东北老工业基 地整体信息化水平提升的主要驱动力；相反，信息量是阻碍东北老工业基地信息化水平提升主要因子(r²=-0.753)。

This study firstly selected 15 indices based on the improved RITE model. Then, the comprehensive informationization indices for the old industrial bases of Northeast China (OIBNEC) and the entire China during 1998 to 2005 were calculated based on these indices. Thirdly, these comprehensive informationization indices were utilized to evaluate the differences of informationization progress between OIBNEC and entire China. Fourthly, the factors contributing to the comprehensive informationization of OIBNEC were ranked based on the results from the Pearson correlation analysis. It was observed that the informationization level of OIBNEC was higher than the corresponding one of entire China by 8.40% during 1998-2005. However, the informationization level of the three provinces located in OIBNEC differed from each other. The ranked order of the informationization level of them were Liaoning >Jilin> Heilongjian. It was also observed that the information equipment (r2=0.991) and the level of correspondence (r2=0.981) were the major driving forces promoting the informationization level of OIBNEC. The information amount (r2=-0.753) was the one reducing the informationization level of OIBNEC. The result in this study indicated that there is a good foundation for the future informationization instruction in OIBNEC.
