中文摘要：

从中美两国1994年至2006年劳动收入及消费相关数据出发，可分析出劳动收入影响消费结构的内在机制。劳动收入影响收入分配，收入分配影响消费总量进而影响消费结构，社会保障和消费信贷对该机制存在影响但相对有限。我国劳动收入占比的下降恶化了收入分配以至不利于居民消费总量的提高和消费结构的优化。所以，当前工作要注意保护劳动者的合法权益，提高劳动者收入。

With the related labor income and consumption data of China and USA from 1994 to 2006, the internal mechanism of how the labor income influences resident consumption structure can be analyzed. Labor income has an impact on income distrlhution which win influence on the total amount of eomsumption as well as the COlnsumption structure, the impact of social security and consumer credit on the mechanism is exist but relatively limited. In China, the rapid decline of the proportion of labor income in GDP has worsened income distribution, which is not conducive to the improvement of the total consumption and the optimization of consumption structure. So the legitimate income of workers should be protected in order to increase the labor income.
