The study aims to define strategic orientations and examine the relationship between entrepreneurial orientation activities and firm performance. For this purpose, the concepts of strategic orientation, entrepreneurial orientation and firm performance are explained in the relevant sections based on the research in the literature. The study used international examples that associate the entrepreneurial orientation of family and non-family companies with firm performance. One of the most important results of the study is that the entrepreneurial orientation of family firms has a weak or non-existent relationship with firm performance. Family businesses tend to be less involved in entrepreneurial orientation activities than non-family companies. Another important result is that entrepreneurial orientation has a more positive effect on the performance of non-family firms than family firms. This study is likely to positively contribute to the literature by providing a new perspective to scientists and administrators and summarizing important resources in one place. The study differs from similar studies as it deals with the relationship between entrepreneurial orientation and firm performance by including family and non-family companies in the process with a holistic approach. Since the samples subject to the study were selected without making any distinction between country, sector and size in this research, the scope is limited. The relationship between entrepreneurial orientation and firm performance could not be determined statistically since the study is qualitative.
