Abstract
The entrepreneurs of Silicon Valley and Route 128 - America’s leading centers of technological innovation - organized politically in the late 1970s. This paper seeks to explain why high tech business associations in these two regions have adopted widely divergent political stances and behavior. It argues that business interests are defined through the process of organization, and that the attitudes of these groups of industrialists were shaped by distinctive political environments, in turn a result of the different industrial and social histories of the two regions. While much scholarly interest has been devoted to the ways in which business affects political outcomes, the paper suggests that the reciprocal causation is equally important: the political environment is an important determinant of business interests.
