利用我国29个省市(除西藏、青海地区外)2000-2008年面板数据,选取13个指标并用主成分法进行合成,构建信息的生产和使用对信息服务业产出的影响模型。结果表明:全国信息生产和使用对信息服务业产出促进作用显著;2000-2005年和2006-2008年两阶段的影响存在差异,现代信息生产因子影响有增强趋势,传统因子有减弱趋势,信息使用总量因子重要性提高;五大区域的影响具有较大差异,长三角、环渤海、珠三角的现代、传统信息生产因子影响都显著高于中西部地区,但其信息使用总量因子不显著。受出口因素影响,长三角、珠三角地区信息使用均量因子对产出影响不显著。
Using the panel data of 29 provinces (excluding Tibet and Qinghai) from 2000 to 2008 in our country, we select thirteen indicators and synthesize them with the principal component method to construct a model of the impact of information production and use on the output of information service industry. The results show that: the national information production and use have a significant effect on the output of information service industry; there are differences in the two stages between 2000-2005 and 2006-2008; the influence of modern information production factors tends to increase; the traditional factors have weaker trends; The influence of the five major regions has great differences. The influence of the modern and traditional factors of information production in the Yangtze River Delta, Bohai Rim and Pearl River Delta is significantly higher than that in the central and western regions, but the total factor of information use is not significant . Affected by exporting factors, the average amount of information usage in the Yangtze River Delta and Pearl River Delta regions has no significant effect on output.
