本文运用2000-2011年中国宽带渗透的省际面板数据,研究了宽带与经济增长之间的关系,发现宽带引入和渗透对中国经济增长起到了显著推动作用,宽带渗透率每增长10%能带动人均GDP年增长率增加约0.19个百分点。分析表明宽带渗透对经济增长的贡献存在一定的网络效应,当宽带渗透率达到约10%后,宽带渗透对人均GDP年增长率的贡献率增加。此外,宽带对东部、中部地区经济发展的推动作用显著,可能的原因是东、中部地区信息化应用水平较高。截止2012年,中国宽带渗透水平以及宽带传输速率与发达国家还有明显差距,并有进一步加大的趋势。

In this paper we investigate how broadband affects economic growth in China using provincial panel data on broadband penetration from 2000 to 2011. We find that the introduction and penetration of broadband has a significant role in promoting economic growth in China. The increase by 10% in broadband penetration raise annual growth rate of per capita by 0. 19 percent. The analysis shows that the contribution of broadband penetration to economic growth has network effects, and its contribution to＇ annual growth rate of per capita increases when broadband penetration rate exceeds 10%. We also find that the contribution of broadband to economic development is more significant in China＇ s east and mid regions, for the informatization level is higher in these regions. The gap between broadband penetration and transmission speed in China and those of developed countries was evident up to 2012 and maybe expand further.
