Purpose: This research aims to study the determinants of Portuguese companies’ capital structure. These results can be useful: 1) as guidelines for capital structure optimization and 2) as a support for efficient decisions in what concerns to capital structure. The literature shows that classical determinants of capital structure present statistical significance and pursue the expected sign for different econometric models tested. Method: The study follows a quantitative design research, with data collected in Amadeus from 500 SME`S in Portugal. The data spans from 2009 to 2018 totaling 4500 observations. We consider three dependent variables, i.e., total, medium and long term and short-term debt. In addition, we also employ seven independent variables (dimension; growth; liquidity; profitability; tangibility; profitability and business risk and singularity). We used a panel data approach based on fixed effects (FE) and of random effects models (RE). Findings: We found that there is no significant divergence of the experimental results obtained in the OLS model, with the fixed effects model and the random effects model, and the expected signals for some independent variables are generally the hypotheses formulated. If we compared both econometric models, it is verified that regardless of the model used, or of the dependent variable analyzed, some of the independent variables are statistically significant in all analyzed models. Furthermore, we also found evidence that the same expected signals are in agreement with the
standard financial theory. These empirical findings may suggest good indicators for making more efficient decisions about the determinants of the capital structure. Research limitations/implications: The main contribution of this work is mainly in which econometric models had best results (according to existing theories) to analyse capital structures of companies. We found that the econometric model chosen for the analysis of the variables must be analysed insofar as some of the independent variables are sensitive to the expected signal and statistical significance, depending on the selected model. Practical implications: These findings will be very useful to top managers in the process of deciding the optimal structure of capital without neglecting the long run financial sustainability of the companies. Originality/value: This study is different because go beyond the classical capital structure determinants and also shows a comparison between different econometric models.
