In particular, the relationship between outcome and the substitution model has been proposed. This study examined a sample of 112 years from 1383 to 1390 at the industry level (about 126 firms) to examine the relationship between competitive structure of the market and policy dividends. In this research the relationship between indicators of competitiveness (industry concentration, product substitutability, market size, market entry barriers and the number of firms) and dividends per share have been tested after considering control variables(such as firm size, profitability, growth opportunities, ratio of retained earnings to total capital, liability ratio) using the combined data. Then using a competition score which is a combination score for measuring competition, the original hypothesis has been tested. The findings suggest that the product substitutability and market size have a positive significant relationship with paying dividend. And there was no significant association between other aspects of the competition and paying dividend. <br />The main research hypothesis was tested using the competition score and positive but non-significant association was found. Profitability which is belonged to control variables showed a significant correlation with the dividend policy.

In doing so, the banks play key roles in the economic growth and development. Due to the increasing numbers of the public and private banks in Iran, predicting their efficiency has attracted significant attentions. This study aims at modeling and predicting the efficiency of the public and private banks by using artificial neural networks, Fuzzy neural networks and genetic algorithms. Using data envelopment analysis (DEA) and considering the total assets and total number of branches as the inputs of the model, the banks’ efficiency has been examined during a period from 2007 to 2011. The outputs of the model include the net profit or loss, the balance of granted credits and receivables. As the next step, the multivariate regression approach, artificial neural network, fuzzy neural network and genetic algorithms have been employed to predict the efficiency of the banks. The findings revealed that the fuzzy neural network is the most precise model in comparison with the other models of predicting efficiency. Based on the sensitivity analysis of the inputs by the neural networks, the net profit or loss has been known as the input with the highest impact on the banks’ efficiency.
