| With the deepening of the construction of China's socialist economic system, our economic have achievivd a series of high-profile splendid achievements .At the same time, some inherent flaw of market economic appeared in gradually. The problem of insufficient demand has become increasingly serious in China, and it has become a bottleneck of further economic continuous, stable and healthy development.In four parts of the total demand in China, the investment demand and government purchases demand continues to rise in recent years, export demand has declined in 2008 after the global economic crisis, and consumer demand presents a trend of continuous decrease. The main reason of consumer demand falls are the decline of income residents and the income gap in residents, and the main reason of these problems is national income distribution mechanism that is not reasonable. Residents with the proportion of total national income lead to a decrease in the level of residents overall income .The results of econometrics model show that income gap, regional gap and industry disparity expand with the residents' consuming level has a negative correlation.The four parts of our total demand, the investment demand, government purchase and export demand is very limited, The sustained power of economic development in the future only is consumer demand. To enhance consumer demand, the most important mission is to improve the existing income distribution mechanism, increase household income in the ratio of gross national income, Meanwhile adjust income gap between the city and countryside, between areas and industries. |
