The main goal is to determine the influence of analytical indicators; in this case these are changes of quantity and average unit price of export and import; over the synthetic indicator - change of trade balance. Next step of this analysis is to calculate the portions of change of inputs volume and change of total productivity of inputs over the change of export caused by change of quantity. To fulfill this aim it is suitable to use methods for pyramidal decomposition of indicators - chain substitution, logarithmic and functional methods. These methods are compared and the results are interpreted.
