The analysis considers Italian small and medium-sized enterprises (SMEs) and investigates, over the years of 2009-2011: the existence of functional relationships between the incidence of trade receivables and payables and corporate profitability; the existence of interdependencies between trade credit policy and trade debt policy; and the coexistence of interchangeable and complementary conditions between trade debts and bank loans and other sources of funding. To verify the research hypotheses, linear regression models on a yearly basis are used and these models are put under observation over the years of 2009-2011. We can conclude that there are interdependencies between trade credit policy and trade debt policy and that trade credit is a source of flexible way of financing, also available in periods of crisis, which has a positive effect on the profitability of SMEs and can be utilized as a complementary and substitute source of financing to bank loans.展开更多

文摘The work investigates the use of trade credit in Italy for reasons of a financial nature. The analysis considers Italian small and medium-sized enterprises (SMEs) and investigates, over the years of 2009-2011: the existence of functional relationships between the incidence of trade receivables and payables and corporate profitability; the existence of interdependencies between trade credit policy and trade debt policy; and the coexistence of interchangeable and complementary conditions between trade debts and bank loans and other sources of funding. To verify the research hypotheses, linear regression models on a yearly basis are used and these models are put under observation over the years of 2009-2011. We can conclude that there are interdependencies between trade credit policy and trade debt policy and that trade credit is a source of flexible way of financing, also available in periods of crisis, which has a positive effect on the profitability of SMEs and can be utilized as a complementary and substitute source of financing to bank loans.
