电信投资对经济增长影响的研究

为引导电信行业制定科学合理的区域投资决策, 实现资源配置的优化。针对2005~2011年中国31个省市的面板数据进行研究, 构建和估计电信投资和经济增长之间的系统结构方程, 研究电信投资对中国经济增长的影响。结果显示, 电信投资对经济增长有显著的促进作用, 其产出弹性达到0.124。电信行业发展迅速, 新业务不断产生, 具有很大的发展潜能, 应该增加对电信行业的投资。分区域考察结果表明, 电信投资对经济增长的影响存在明显的区域非均衡现象, 西部地区电信投资的经济增长效应远大于中部和东部, 而东部地区电信投资转化为电信普及率的效率高于中部和西部地区。

Research for Effects of Telecommunication Investment on the Economic Growth

In order to help the telecom industy to make more scientific and area investment decision\|making. We study how telecommunications infrastructure in
vestment affects economic growth of China by estimating a structural model with the data set covering 31 provinces from the year 2005 to 2011. We find that telecommunications investment on economic growth has a significant role in promoting, and the output elasticity of telecommunication investment is 0.124. The telecommunication industry is developing rapidly, new services emerge, with good growth potential, should increase the investment of telecom industry. And the empirical study on different regions reveals that there is distinct regional disequilibrium that the investment contribution to productivity in the West is much higherthan that in the others. While In telecommunications investment into telecommunications penetration, the eastern region has the highest efficiency.
