For small and medium-sized enterprises (SMEs), innovation plays an important role in remaining competitive as business conditions change. While previous research has linked leadership to innovative behavior, less is known about the psychological processes underlying this relationship. This study investigates how charismatic leadership relates to perceived team innovative behavior in Turkish SMEs, with particular attention to the possible mediating role of employees&rsquo; self-concept. We used a quantitative, cross-sectional design and administered an online questionnaire to employees of SMEs in Mersin, Turkey. After data screening, 250 valid responses were used to evaluate the measurement and structural models using partial least squares structural equation modeling (PLS-SEM) in SmartPLS.Charismatic leadership was positively associated with perceived team innovative behavior and employees&rsquo; self-concept. Employees&rsquo; self-concept was also positively associated with perceived team innovative behavior. The estimated indirect effect of charismatic leadership on perceived team innovative behavior through employees&rsquo; self-concept was positive but small. The percentile bootstrap 95% confidence interval did not support statistical significance. The findings indicate positive associations among charismatic leadership, employees&rsquo; self-concept, and perceived team innovative behavior in Turkish SMEs. These findings suggest that leadership and employees&rsquo; perceptions of themselves are relevant to innovation-related behavior, although further research using longitudinal data and improved measurement models is needed<span lang="TR" style="font-size: 11.0pt; mso-ascii-font-family: Garamond; mso-fareast-font-family: Calibri; mso-hansi-font-family: Garamond; mso-bidi-font-family: Arial; mso-bidi-theme-font: minor-bidi; mso-ansi-language: TR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">.

Charismatic Leadership and Perceived Team Innovative Behavior in SMEs: The Mediating Role of Employees’ Self-Concept

During the last few decades, business philosophy has shifted from marketing orientation to Relationship Marketing Orientation (RMO). Service oriented organizations, such as banks, increasingly apply RMO to enhance their brand management practices, such as brand loyalty and brand image. The main purpose of this study is to investigate the influence of relationship marketing orientation and its dimensions (trust, bonding, communication, shared values, empathy and reciprocity) on the Brand Equity in Saderat Bank. Data were collected from 339 customers across various branches of Saderat Bank in Ardabil, Iran. Confirmatory factor analysis and structural equation modeling were used to analyze the measurements and relationships among the variables. The findings of this study demonstrate that RMO has a positive effect on the brand equity of Saderat Bank. Specifically, dimensions including trust, bonding, empathy, and reciprocity have direct and significant effects on brand equity, with the effect of trust being significantly higher. However, communication and shared values showed no significant effects on brand equity. The findings of this study offer practical applications for enhancing the brand equity of banks and other financial institutions, particularly Islamic banks, by exploring the cultural variation of relationship marketing.
