Thiscommunication explores the determinants that explain the propensity to engage in long-distance business travel. The data used come from the National Transport and Travel Survey conducted in 2008 with a representative sample of the French population. Following a review of the literature, a logistic regression analysis on the probability of an individual having taken at least one business trip in the last three months, shows that the most significant determinants are the socio-professional category, attachment to the public or private sector, income, gender and the nature (and especially the size) of the workplace location.
