Source Of Value And Value Study

Based on Marx's labor theory of value, the paper is intended to analyze the source and quantity of value. Based on the understanding of value, labor, production labor, product and goods, the paper analyzes the source of value .We think that the living labor is the only source of creating value, and other production factors only can transfer their value but can't create the new value. Then, we analyze the labor creating value as well as labor creating value in the third industry. Labor which can create value needs three conditions. The first is the working fruit is production; the second is that production need consuming labor; the third is that production need be exchanged. According to this standard, we think that the circulation department and service department as well as culture department of the third industry are the creating value departments, but the commonality service department can't create value.On the side of the quantity of value, the paper analyzes the matters affecting department value and value gross as well as value rising. Department value is the value of a kind of goods. The paper analyzes the functions of two meanings time on value. Firstly, we think they have the functions on value together. Secondly, the department labor production rate has the inverse ratio relation with the unity goods value, and the different value of different producer is caused by their own labor production rate. Thirdly, we also think that the value gross which producer can obtain has the direct ratio relation with their own labor production rate. Value of all departments can add up to value gross. On the side of value, the difference of the different labor is that they can create different quantity value in the same time. Because they are different complexity degree labors. We think that labor complexity degree and time have functions on value together. Last, using the theory of national accounts, the paper analyzes the quality of GDP and the reason about value rising. The paper think that GDP accounted by current price is the value quantity index and GDP accounted by past price is neither the value quantity index nor the use value quantity index. On the condition of slow increasing speed of labor force, we think thatthe reason of value rising is the improvement of labor complexity degree.
