中国省域城镇居民信息消费差异分析

The Research on Differences of Information Consumption in China Provincial Urban Residents

本文基于2000-2012年间中国31个省域城镇居民信息消费数据,借鉴区域经济差异分析方法,采用空间统计分析和空间计量模型,对中国省域城镇居民信息消费差异进行了实证分析。结果表明中国城镇居民信息消费稳步增长,信息消费差异呈现较平缓的先发散后收敛的"倒U"型趋势,但收敛趋势相比发散阶段较平缓;信息消费具有显著的空间集聚性和异质性,信息消费不存在绝对收敛,但是存在中、西、东部梯度递减的条件收敛。

Based on China＇ s 31 provincial urban residents information consumption data of 2000-2012 years, and the methods applied in economic growth regional differences analysis, the paper aims at doing some detail research about the differences of information consumption in Chinese provincial urban residents by using the spatial statistical analysis and spatial econometric model. The research results show that there has been a steady rise in China＇s urban residents informa- tion consumption, the overall difference of information consumption presents for more flat ＂inverted U-shaped＂ curve, com- pared to the previous trend of convergence, convergence stage is relatively flat than the first stage. And moreover, informa- tion consumption has a significant spatial concentration and spatial heterogeneity, there is no absolute β convergence in China, but there are gradually decreasing conditional convergence within the West, middle and east regions in China.
