The most popular measure of concentration, Gini coefficient G, does not show uniformly all the changes taking place in a flow of goods between objects. This work presents alternative index of concentration IC that when used together with Gini index mitigate that inconvenience. Studies have shown that coefficient IC differs considerably from Gini index in sensitivity to flow of ”good”. The coefficient IC is more sensitive because it depends on value of change quadratically while Gini index only linearly. IC depends on coordinates more properly than G as it depends on difference in values of coordinates opposite to G which depends on difference in positions of coordinate.
