The Effect of Transformational Leadership and Organizational Culture in Organizational Innovation Attending to the Organization Size

The present study was aimed to explore the role of organizational size in the relationships between leadership, culture and innovation. The data were collected from 102 Portuguese organizations, with different sizes, from where a total of 854 workers answered a questionnaire concerning the leadership and organizational culture within their organization and 102 top managers answered a questionnaire concerning the innovation activity in their organization. A structural equation modelling demonstrated that the variable size of the company acts as a moderator, producing differential effects not only on the leadership role in the relationship between culture and innovation, but also on the contribution of each indicator to innovation.
