摘要
利用2001年至2008年中国31个省、直辖市和自治区的面板数据验证信息基础设施对中国经济增长的影响,并在此基础上分析信息基础设施对中国不同区域经济增长贡献的大小。基于宏观总产出方程与信息基础设施微观供需模型相结合的联立方程模型控制信息基础设施内生性,采用人均长途光缆线路长度作为信息基础设施的代理变量测度信息基础设施对经济增长的贡献。实证研究结果表明,信息基础设施对中国的经济增长有显著的正向促进作用,基于信息基础设施对各地区经济增长的复合增长效应的测算表明,信息基础设施对中国经济增长有很大贡献,但是信息基础设施对不同区域增长的贡献与经济增长的状况却存在反差。在西部不发达地区,信息基础设施的发展对经济增长的促进作用要高于全国水平,而中部各省信息基础设施的发展却低于全国水平。
Based on the panel data of 31 provinces in China from the year 2001 to 2008,we investigated the contribution of information infrastructure to economic growth in China and analyze the contribution effect in different regions of China.Using Simultaneous Equations Model（SEM） with the macro-aggregate output equation and micro supply and demand model to control the endogenous of information infrastructure,we estimate the contribution of information infrastructure to economic growth with the proxy of information infrastructure being the length of long-distance optical cable lines per capita.The empirical study shows that information infrastructure has a significant influence on China′s economic growth.When calculating the contribution of different provinces in China by compounded annual growth effect（CAGE）,we found that the contribution is significant,but varies in different regions.In western provinces,the contribution is higher than the country average while it is lower in central provinces.
