Abstract: This paper divided the added-value of the farmland for Non-agricultural used into three stages,and calculated the amount of the added-value and it's unfair distribution using Gini coefficient of the farmland for non-agricultural used of the 26 cities of the Yangtze River Delta. A method improving the fair distribution of the added-value was discussed in the end of this paper. The results showed that the farmland for non-agricultural used gained added-value in the collection stage,transfer stage and development stage,and the added-value gained by farmers,government,and the developers,the distribution ratio was about 1:3:6. The Gini coefficient of the added-value distribution of the farmland for non-agricultural used of the 26 cities of the Yangtze River Delta was 0.4,which was the international warning line,and would be guarded. The Shapley value method for the distribution of the benefits was according to the degree of the contribution of the participants in the cooperative game,and it would has a certain enlightenment significance for improving the fair distribution of the added-value.
