我国农村和城镇居民人均可支配收入对消费支出的影响对比研究——以江西省为例

Comparative Study on the Influence of per Capital Disposable Income on Consumption Expenditure of Rural andUrban Residents—A Case Study of Jiangxi Province

摘要: 中国经济进入新时代后，消费、投资、进出口对经济增长的拉动作用发生了明显变化，江西省的地理位置属于中国的中部地区，进出口贸易贫乏对该省的经济发展作用并不显著，同时该省投资方面的支柱性产业比较少，所以相对而言消费就逐渐成为该省经济增长的主要动力。就总体消费而言，居民消费支出占比较大，然而影响居民消费的核心因素是可支配收入，因此，研究居民人均可支配收入对人均消费支出的影响就显得尤其重要。通过收集2005~2021年江西省居民人均收入与消费支出相关数据运用stata.17软件进行统计分析，并采用凯恩斯消费函数理论来构建计量经济模型，通过农村与城镇这两个方面对江西省居民的人均可支配收入对消费支出的影响对比分析，得出区域不同导致的两个变量之间的影响程度也有所差异，从而有针对性的提出建议来提高居民消费促进经济发展。

Abstract: Since China’s economy has entered the new era, the driving effects of consumption, investment and import and export on economic growth have changed significantly. Jiangxi Province is located in the central part of China, and the lack of import and export trade has no significant effect on the economic development of the province. Meanwhile, the province has few pillar industries in terms of investment. So relatively speaking consumption has gradually become the main engine of economic growth in the province. In terms of overall consumption, consumer expenditure accounts for a relatively large proportion, but the core factor affecting consumer consumption is disposable income. Therefore, it is particularly important to study the impact of per capital disposable income on per capital consumption expenditure. By collecting data related to per capital income and consumption expenditure of residents in Jiangxi Province from 2005 to 2021, Stata.17 software was used for statistical analysis, and Keynesian consumption function theory was used to build an econometric model. The impact of per capital disposable income of residents in Jiangxi Province on consumption expenditure was compared and analyzed from rural and urban aspects. It is concluded that the influence degree between the two variables caused by different regions is also different, so as to put forward targeted suggestions to improve residents’ consumption to promote economic development.
