中文摘要：

随着信息社会的到来，信息化对区域经济社会的影响成为国内外研究的热点之一。西方经验研究表明，1990年代以来，信息化对发达国家经济社会发展产生了显著的影响，不同国家信息化产生影响的特征不尽相同。文章分析了近10年来信息化对江苏省经济社会发展的影响，认为信息产业发展迅速，信息服务业对经济总量增长的贡献比信息制造业更为显著。通过对边际贡献的分析，江苏省信息消耗对GDP的边际贡献远远大于全国平均水平，信息对经济发展有较强的拉动作用。通过分析失业率和区域差异的变化，探究了信息化对江苏省社会发展的影响，结果发现随着信息化水平的不断提高，全省失业率表现出驼峰曲线的特点，并且区域差异表现出扩大趋势。
