The role of environmental innovation through the technological proximity in the implementation of the sustainable development

摘要

This paper explores the relationship between a firm's knowledge sourcing strategy and green innovation. The data are taken from Organisation for Economic Cooperation and Development REGPAT database, February 2016, relative to the European Patent Office firms' patent applications published up to December 2015. The study contributes to the literature by focusing on the moderating role of integration between different activities related to environmental performance on the relationship between knowledge sources and green innovations. The results from 240 firms indicate a shift in the focus from internal knowledge to external knowledge when developing environmental innovations. Government policies promoting more knowledge complementarity and coordination between environmental fields will help to promote more knowledge transfer, allowing more sustainable development.
