ABSTRACT.
The paper analyses and discusses the random variable index. First, a random input-output model is established for the direct consumption system and final demand of various industrial sectors. Secondly, the paper establishes a random price model for each department and finds the random variable input and output models of direct consumption coefficient and input coefficient of each department. Finally, the thesis demonstrates the theoretical value and practical significance of the model.

Keywords: random variable index; economic variable; input and output; random distribution.
