The article studies the adoption of eco-innovation using the diffusion dynamic as a paradigm for investigating the environmental
reform in providing public goods. The study focused on the wastewater collection systems and analyzed how the structure of the
market, socio-cultural conditions, geographic proximity and the Gross Domestic Product level measured the acceptance or
rejection of eco-innovation. The authors investigated the data in order to test three hypotheses, respectively, the influence of the
period of adoption, general country economic performance, and neighborhood conditions in eco-innovation adoption. The
hypotheses were tested using statistical and geostatistical techniques. The study concluded that the adoption rate slows as the
saturation level is approached and early adopting countries have a broader uptake of the innovation than do latecomers, even
though the latecomers enjoy the benefits of leapfroggers. In addition, the study found that geographic proximity influenced who
was an early adopter and who was a laggard. The results illustrated that the general economic performance of a state does not
directly influence eco-innovation adoption.
