广东城镇居民信息消费边际倾向研究

The marginal propensity to research on the urban residents' information consumption of Guangdong province

应用协整理论与误差修正模型对广东省城镇居民2004—2013年信息消费的边际消费倾向进行了分析.结果表明:信息消费增长迅速,交通通讯类消费增长幅度最高;截面数据的拟合优度较高,信息消费的收入弹性良好,信息消费的边际消费倾向与人均可支配收入增长率存在一定的相关关系;当可支配收入增长率逐年递增时,信息消费的边际消费倾向却出现下降的趋势,城镇居民信息消费的增长幅度小于可支配收入的增长幅度;建议通过扩大需求、培育市场以及改善环境等措施推进广东城镇居民信息消费的健康发展.

The information consumption marginal propensity of urban residents in Guangdong province from 2004 to 2013 was analyzed with co-integration and error correction model. Results showed that there was a rapidly growing of information consumption and the rate of transportation and communications was the highest. Both of the cross section data and the income elasticity were reasonable. There was a certain correlation between information consumption marginal propensity and growth rate of disposable income per capital. The information consumption marginal propensity decreased with the yearly increase in disposable income growth per capita. Moreover,the increase rate of the urban residents’ information consumption was lower than the one of disposable income. Proposals were given to expand demand,cultivate the market and improve the environment to promote the healthy development of information consumption of urban residents in Guangdong province.
