The paper reports the results of a study examining the diffusion of innovations across four different units of local government. Using partial correlation coefficients to test a hypothesized model, the variables were successful in explaining the adoption of process innovations but showed limited success in explaining product adoptions. Socioeconomic variables were not found to be significant direct determinants of innovation. Demands for innovations, organizational characteristics, and the organizational environment were much more important predictors of the use of innovations by local governments.
