Abstract: By making use of the panel data of China’s 30 provinces from 2000 to 2012, this paper conducts an empirical study of the effect of new urbanization and system changes on household consumption growth. The results show that the new urbanization has always had significant positive effect on household consumption growth, while the three system changes (including land, household registration and social security) have no obvious effect; instead, they are even playing a role of blocking. Further analysis with a lag model shows that changes of land system have a significant lag-behind effect, while the lag-behind effect of the changes of household registration and social security system is positive but not significant. There is a larger gap between the theoretical expectation and the result of the exploration of the combined effect of new urbanization and the changes of the three systems on the household consumption growth. As you can see, the present three systems have become a bottleneck to new urbanization development and household consumption growth. Therefore, in order to implement the new urbanization strategy out-and-out and give full play to its role of growth engine to stimulate domestic demand and promote household consumption growth, it is necessary and urgent to innovate the land system, the household registration system and the social security system.

Key words: new urbanization; land system; household registration system; social security system; household consumption growth
