Resumen
Entrepreneurial intention is a key research question in entrepreneurship. Previous studies have proven the theory of planned behavior (TPB) to explain entrepreneurial intention. Scholars have thus focused on analyzing factors to develop the three antecedents of TPB, one of which is social capital. However, research has barely considered social capital online. We extend research by exploring the effect of social capital on these antecedents and on entrepreneurial intention, and by analyzing the differences in these influences between social capital online and offline. Using partial least squares and commonality analysis for 587 individuals in Spain, we find that social capital influences these antecedents and entrepreneurial intention. Furthermore, social capital online has a greater effect in attitude toward entrepreneurship, a similar effect on perceived behavioral control, and a lesser effect on social norms than social capital offline. Finally, social capital online has a greater influence on entrepreneurial intention than social capital offline.
