数字鸿沟的模型分析及应用ICT缩小数字鸿沟的实证研究

Model Analysis of Digital Divide and Empirical Study on Its Narrowing with ICT

针对区域间的信息化差异导致的数字鸿沟问题,借鉴Keith Griffin关于农业绿色技术革命产生和传播的模型,绘制出包含信息等量曲线的ICT(信息通信技术)传播模型.并运用模型分析了信息化发展不同阶段使用者对信息通信技术的不同选择,并且依据处在不同阶段的信息等量曲线与不同使用者的资产与劳动的比率相交确定出一个ICT缺口,这个缺口之间的差距可以用来描述数字鸿沟的大小.最后使用信息化指数测度的方法对辽宁省信息化水平做了实证分析,实证结果证明了应用ICT是缩小数字鸿沟的行之有效的方法,提出进一步应用ICT和缩小数字鸿沟的建议.

The appearance of digital divide due to regional informational discrepancy is studied using Keith Griffin＇s model which was developed for the generation and propagation of the Green Revolution for agricultural production to develop an ICT propagation model, involving the information isoguants plotted. The ICT model is used to analyze user＇s different choices of communication technologies in different stages of informational development, and an ICT gap can be determined by the intersection of the isoquants in different stages and the capital-labor ratio of different users. The ICT gap can describe the size of the digital divide. An empirical analysis is made for the information popularization level in Liaoning Province by popularization index measuring. The results show that ICT is an efficient way to narrow the digital divide and give suggestion on how to further develop ICT and narrow the digital divide.
