چکیده

هدف محوری این مقاله ارزیابی کشش درآمد نسبت به قیمت نهاده­ها و سنجش اندازه رقابت در بازار بانکی ایران در شرایط لحاظ نمودن اهرم مالی و ریسک­های بازاری بر اساس رویکرد پانزار-راس می­باشد. در این مقاله بازار متشکل پولی ایران شامل 18 بانک فعال در بازه  زمانی 1393-1386 مورد بررسی قرار گرفته است. نتایج تحقیق نشان می­دهد که بازار متشکل پولی کشور، در دوره مورد مطالعه در وضعیت رقابت انحصاری قرار دارد و مقدار آماره H در این پژوهش برابر با 77/0 می­باشد، همچنین با استفاده از آماره نرخ بازده بلندمدت  ( HROE)نشان داده شد، که بازار بانکی ایران در  بازه زمانی مورد نظر در تعادل بلند مدت قرار دارد. یافته­های پژوهش موید این نکته می­باشد که اهرم مالی، رشد تولید ناخالص داخلی و شاخص تمرکز، متغیر جایگزین مناسبی برای ارزیابی کشش درآمد نسبت به قیمت نهاده­ها و سنجش اندازه رقابت بر اساس رویکرد پانزار-راس می­باشند. با توجه به یافته­های تحقیق دولت می­تواند با رفع موانع ورود به شبکه بانکی و نیز اعطای تسهیلات و تشویق بخش خصوصی برای حضور در بازار بانکی، راه را برای حضور بانک­های خصوصی هموار سازد و باعث افزایش سهم بانک­های خصوصی شود. این امر می تواند باعث افزایش رقابت و بهبود کارایی عملکرد بانک­ها در شبکه بانکی کشور شود.

چکیده [English]

The main objective of this paper is to assess the income elasticity with respect to input prices and measure the size of competition in the Iranian banking market in the presence of funding risk (leverage) and business risks based on the Panzar-Rosse approach.The existence of competitive financial markets is very important in the economy. Banks in the form of the organized money market are one of the main pillars of financial markets. They play different roles in financial markets. In this paper, the Iranian organized money market is investigated, including 18 banks operating in the period of 2007-2014. The results suggest that the banking market of the country is closer to the monopolistic competition during the studied period and the value of the H-statistic equals 0.77.As already stated, the Panzar-Rosse H-statistic is a measure for evaluating the competitive structure of a financial market (bank), which is equal to the total elasticties of the bank's total income with respect to the price of bank inputs. Also, using the HROE statistic, we showed that there is no relationship between the rate of return and the price of inputs, that is, the Iranian banking market in the long-run has equilibrium in the studied period. Also, the findings prove that funding risk (leverage) has a significant role in assessing the size of the banking market competition based on the Panzar and Rosse models.
