Dynamics of environmental technological capacity: An analysis between developed and developing countries (1990-2015)

The literature on national innovation systems highlights that investments in environmental innovation are influenced by the magnitude of the multidimensional characteristics of each economy. In order to build the possible bases for environmental technological development, countries need to advance in several issues related to scientific, technological, educational and health infrastructure. Thus, the article aims at investigating the evolution of different characterizations (developed and developing countries), in the period between 1990 and 2015. For that purpose, the methodology applied was Principal Component Analysis (PCA) and regression model with panel data. The results revealed that scientific characteristics and gas emissions were determining factors for the countries' innovative environmental performance over the years, especially developed ones. Furthermore, efforts were made by developing countries such as Brazil, China and India, in favor of a new environmental technological paradigm.
