中文摘要:

      应用LMDIⅠ方法对北京市2001—2012年居民总消费的增量进行了结构分解,得到北京市城乡收入差距变化对北京市总消费的影响。然后,通过Pearson相关系数、面板回归等方法对分解结果进行进一步的分析。研究结果表明:北京市城乡收入差距的变化与城乡收入分配效应正相关,即北京市城乡收入差距的扩大并未对北京市总消费起到抑制作用。最后,给出了可能的原因解释,并基于研究结论提出了相关政策建议。

英文摘要:

      Based on the Logarithmic Mean Divisia Index (LMDI) I decomposition approach, this article decomposes the incremental change of Beijing residents' general consumption during the period from 2001 to 2012 to evaluate the effect caused by the change in income gap between urban and rural residents. In order to analyze the data gained above deeply, this article calculates the Pearson correlation coefficient and makes panel regression on them. The research finds that the change in income gap between urban and rural residents has a positive correlation with the corresponding effect, which implies that no evidence shows that the expanding income gap between urban and rural residents has contributed to the slow growth in residents' general consumption. Finally, possible reasons are provided and policy suggestions are proposed accordingly. 
