Abstract:
This paper aims to evaluate the impact of several indices of market structure including entry to barrier, economies of scale and concentration degree on ۱۴۰ active industries using the digit. Accordingly, we apply three methods including cost disadvantages ratio ( ), Herfindahl–Hirschman concentration index ( ) and Comanor and Willson criterion in order to assess the economies of scale and using the Roger's approach for measuring the Mark up level () in the industries. Hence, in this study first we cluster ۱۴۰ industries according to the neural network under a radial basis function (RBF) and then identify the mark up level by extracting the rules indicating the relationships of structural variables of the market (i.e. concentration, entry to barrier and economies of scale).
