Leadership styles that managers use in order to survive and gain a competitive advantage are an important building block for businesses. The aim of this study is to determine the different leadership styles (transformational and transactional) of managers and to reveal whether the demographic and firm characteristics of these managers affect their leadership styles. In the study, transformational and transactional leadership styles are chosen, especially from modern leadership styles. Therefore, it has been applied to the industrial enterprises operating in the Van Organized Industrial Zone, as its deficiency has been identified in the literature. 65 of 126 businesses registered in the region have been reached. Some of the businesses stopped their activities and some did not want to participate in the survey. The businesses that participated in the survey are mostly active in the manufacturing, food, and construction sectors. Multifactor Leadership Styles Scale- (MLQ) with 36 questions developed by Bass and Avolio in 1995 was used to collect data. As a result of the research, it was determined that company managers use the transformational leadership style more. Considering the demographic factors, it has been determined that women use transactional leadership style more while managing their companies. When analyzed on the basis of firm characteristics, it has been determined that there is a significant relationship between the size of the firm, the sector in which the business operates, and the legal structure of the business and its leadership styles. It has been determined that there is no significant relationship between managers 'age, role in the company, working experience, and educational level, business environment, and capacity utilization rates variables and managers' leadership styles.
