This section aims to examine the relationship between managers' social capital and their propensity to form strategic alliances. The study is based on quantitative data obtained from the company's managers. Data were collected from 322 managers through face-to-face and online surveys. Frequency analysis, descriptive statistics, factor analysis and correlation analysis were used to obtain the findings. The results of the study indicate a positive relationship between strategic alliance propensity and social capital. In other words, managers make decisions influenced by social capital dimensions when forming strategic alliances. The relationship-building and maintenance dimension has a greater impact on unity of purpose and action. Instilling trust also has a moderate impact on unity of purpose and action. However, there is a low-level positive relationship between the other dimensions. As expected, social capital dimensions are one of the important variables considered when forming strategic alliances.
