According to domestic and foreign study about insufficiency in consumption ,this paper try to find out what leads to insufficiency in consumption in Guangdong province,then give some advices to solve the problem.I mainly study the influence on consumption by the enlargement of income gap between townsmen and farmers, by innovation as well.When I make contract between total income and income gap ,I find that income gap is by far important to consumption than total income,so I propose to shrink the income gap.When I analyse innovation’s effect on consumption ,I find that the previos innovation is close related to current consumption and find out that the low growth rate of previos innovation leads to the low growth rate of current consumption,so I suggest that govenment should encourage enterprises to creat more and eliminate backward production.In addition, there are other reasons contributing to low consumption rate,such as uncertainty. According to different reasons,I propose my different approaches.
Key words: Consumption Demand Income Gap Innovation
