A Research of the anti-price equilibrium of bank card consumption

Since the birth of the first bank card in 1950´s, bank card has become one of the most important financial tools. Bank card industry chain constitute the bank card associations, issuing banks, acquiring banks, related products and technology suppliers, which is a bilateral market. The bank card has become a typical network product. Currently, there are still contradictions between businesses and banks, which is the result of the unbalance distribution of profit among banks. In this paper, based on the bank card POS transaction mechanism, authors extend the anti-price equilibrium model of Shy. We compare different banks´ transaction business in some respects of equilibrium price level & profit level and discuss the pricing factors and price profit changes by extending the anti-price equilibrium model.
