中国城镇居民信息消费水平估计与收敛性分析

摘要

基于面板数据对2002—2013年中国城镇居民信息消费水平进行了估计，并进一步研究了其收敛性。结果表明：城镇居民信息消费水平存在较显著的地区差异，最高收入省份的消费水平与最低收入省份的消费水平差距呈扩大趋势；信息消费水平不具有σ收敛性，也不存在绝对β收敛的情况；但是存在不可观测的个体异质性变量能促进收敛，存在条件β收敛性；引入空间相关性后，收敛速度加快，并且其相邻近地区信息消费水平增长率的误差冲击产生正向作用。%Based on the Chinese provincial data of information consumption from 2002 to 2013,the information consumption level of urban residents in China is estimated.Its convergenceare studied.The result show that there have notable district difference of information consumption level,and the gap between highest level province and lowest level province is extending.The information consumption level havenoσconvergence and no absoluteβconvergence.The results of having conditionalβconvergence are obtained by introducing the individual heterogeneous variable.The conclusion of convergence speed is quickened after introducing the spatial dependence.The adj oiningprovince error shocks of information consumption level growth rate increasing exist notablepositive effect.
