The paper studies the degree of homogeneity of innovative behavior in order to determine empirically an industry classification of dutch manufacturing that can be used for policy purposes. Defining homogeneity in terms of an economic model distinguishes our classification from existing taxonomies such as those of the oecd, pavitt and the various classifications based on a principal components analysis. We use a two-limit tobit model with sample selection, which explains the decisions by business enterprises to innovate and the impact these decisions have on the share of innovative sales. The model is estimated for eleven industries based on the dutch standard industrial classification (sbi 1993). A likelihood ratio (lr) test is then performed to test for equality of the parameters across industries. We find that dutch manufacturing consists of three groups of industries in terms of innovative behavior, a high-tech group, a low-tech group and the industry of wood. The same pattern shows up in the three dutch community innovation surveys.
