摘要：This paper studies the determinants of capital structure of 2,329 Portuguese small firms, decomposing total liabilities in long and short-term debt. The results of 2007-2011 panel data suggest that information asymmetry and agency problems seem to be important for small firms in accessing long-term debt. Greater size and a higher level of collateral are quite important in accessing long-term debt. Liquidity is positively associated with long-term debt, although it is negatively related to short-term debt. Higher profitability is related to lower levels of debt. When internal finance is insufficient, these firms seem to be strongly dependent on short-term debt, due to the difficulties in accessing long-term. The main conclusion of the current study is that the predicitons of POT and TOT are followed by small firms in their capital structure, which is in accordance with the results of previous studies focusing on SMEs.
