Ajzen’s Theory of Planned Behaviour (TPB) suggests empirical implications to
promote students’ entrepreneurial intentions. In the course of an empirical study
with 208 German students, regression analyses confirm that attitude, social norm,
and perceived behavioural control contribute substantially to the prediction of
start-up intentions. The use of index based measurements shows that entrepreneurial
intention is significantly influenced by all three constructs (R2 ¼ 0:446).
As beliefs based on information and experiences are decisive in order to emerge
an intention, a promoting approach should start here. Following the TPB, changes
at singular points are not sufficient. A discussion of concrete beliefs provides
implications for future research as well as for practical interventions.
