The aim of the paper is to present the concept of the small entrepreneur’s credit mentality, which was introduced, grounded, empirically verified and popularized in Polish literature by T. Łuczka, and to indicate its role in the development of research on entrepreneur-ship and SME sector companies. This aim was achieved through a literature review, with particular emphasis on studies and research projects inspired by the concept of a small entrepreneur’s credit mentality. The analysis shows that this concept is very useful for describing and interpreting the financial management activities of SMEs and certain economic phenomena (e.g. market demand for bank credit). Moreover, it constitutes a significant inspiration for other authors to conduct further in-depth research in the area of entrepreneurship and small business management. The main directions of this inspiration were identified as: 1) considerations in the field of identification, description and interpretation of the specificity of SMEs, 2) studies in the field of the influence of psycho-personal characteristics of entrepreneurs and behavioral and cultural factors on entrepreneurship and small business management, 3) analyses concerning barriers to the activity and development of SMEs, as well as 4) works on the causes, conditions, course and effects of the presence of this specific attitude in various types of small economic entities. The literature review indicates that in the future we may expect further scientific considerations and the opening of new research areas inspired by T. Łuczka’s concept of the small entrepreneur’s credit mentality.
