The Entrepreneurial Orientation (OE) reflects a company s propensity to engage in innovative, proactive behaviors and to take risks in order to achieve its goals. In an increasingly competitive and globalized context, this field has been consolidated as one of the most fertile in the strategic management literature, attracting the interest of researchers willing to investigate how companies should explore this entrepreneurial stance to improve their desempenho. Within this context, a relevant resource for SMEs is the use of the network created around the company to improve their business. In view of this, the present research proposed to empirically analyze the impact of entrepreneurial orientation on the financial and operational desempenho of small companies, also evaluating the moderation of the business network in this relationship. For this purpose, data were collected from 155 small companies in Rio de Janeiro registered in SEBRAE, for further analysis using the hierarchical regression method. The results of the study demonstrated that entrepreneurial orientation contributes to improvements in both financial and operational desempenho. In addition, it was found that the business network did not play a moderating role in either of these two relationships. Based on these findings, academic contributions and managerial implications were elaborated, as well as limitations and suggestions for future research.
