中衛翻譯公司關鍵字：I. IntroductionIncome consumer base. According to Marx's theory of social reproduction and social reproduction cycle of the product must go through the production, distribution, exchange, consumption of four links, distribution and exchange of production and consumption is linked bonds. Distribution in the material production sectors of material production departments formed the income, including income and in-kind monetary income, in the field of exchange of the redistribution of national income, making the non-material production sector workers earn. Their income in wages, profits, rent, interest and other forms of existence, is to ensure that residents receive income for the necessary social conditions for the successful reproduction, because reproduction of wage labor factors of production out of condition; capitalists to invest in profit is the driving force of reproduction; land rent is to ensure that the land owner to obtain factors of production in the conditions of social reproduction; interest is the cost of funds for social reproduction and so on. Based on this, we can conclude: income distribution and exchange is an important carrier, distribution and exchange is a prerequisite consumption, so consumption of base income. China's traditional planned economy system, the residents, mainly through the initial distribution of social goods to obtain money in the form of wages and income redistribution in the form of rationing access to in-kind income is not well-developed form of personal exchange, monetary income of the consumer's decision effect is not large; reform and opening up the market economy gradually developed, monetary income of the decisive role of consumption gradually increased, to link the currency as a medium of exchange, that the market circulation to develop. At this point, people get way more consumer value in the form of income by expenditure and income of residents in money and in kind by the co-existence of two forms into the main form of currency. Monetary income which should be washed to determine their consumption level and structure. In other words, the traditional planned economy, in-kind income and monetary income of the common consumption level and structure of the decision; in the commodity economy, the monetary income mainly determines the consumption level and structure.
Western economic theory depicts the relationship between income and consumption are more systems are mainly based on "consumption is a function of income," the quantitative relationship between the assumption that C = F (Y), to build the consumption function, but not the assumption that the premise the same. Here we do not fully agree with the Western theory of the consumption function, but its definition of current income, permanent income, relative income concept for the interpretation of consumer demand in China's current situation or has some explanatory power.
Second, Keynes's absolute income is assumed based on empirical analysisKeynes' absolute income assumes, "The central idea is decreasing propensity to consume, current consumption depends on the consumer's current period net income, the" absolute income. " Accordingly, the model:
C = a + bY ---------------------------------( 1)Where, C is current consumption, a is the spontaneous consumption, b is the marginal propensity to consume, Y is current income.
C and Y in order to eliminate non-linear relationship between the impact of return on (1) for the double logarithmic transformation, to eliminate the C on the Y non-linear effects related to the return, are:
