宽带对我国国民经济增长的影响

Impact of Broadband on China's Economic Growth

为了量化研究宽带渗透率对经济的促进作用,并克服宽带渗透率与经济增长之间的内生性问题,建立了宽带渗透率的宏观总产出方程与微观供需模型相结合的联立方程模型,并运用中国2001—2010年的面板数据进行实证分析。结果表明,宽带渗透率每提升10%,将带动国民经济提升0.424%。

In order to quantify the impact of broadband on economic growth and solve the endogeneity problem between broadband and economic growth, simultaneous equations model which combines macro output equation and micro supply and demand equation of broadband is constructed, and empirical analysis is made based on the data from the year of 2001--2010. Empirical analysis shows that the rate of broadband penetration each increa- ses by 10% , and the growth rate of national economy will be raised by 0. 424%.
