Abstract
The purpose of the paper relies on the analysis of the differences in service vs. manufacturing and operational-based vs. knowledge-based firms when innovating taking the environment in consideration. Specifically, we want to compare if the type of industry, manufacturing or service and knowledge-based or operational-based industries, affects the direction and/or strength of the relation between the variables in the model in order to determine specific differences that may justify different policies to promote the environmental orientation of the firms. As Henseler et al. (2009) indicated, group effects are nothing more than a variables moderating effect. Then, we are interested in analyzing the moderating effect of these four types of industries related to structural model
