Lean, green practices and process innovation: a model for green supply chain performance

This paper investigates the relationship between lean, process innovation, green practices and green supply chain management performance. Data were gathered by surveying 374 firms in the manufacturing supply chain industry. Structural equation modeling (SEM) was employed to analyze the collected data. The study results show general support for the theoretical research framework. Findings reveal that there is a synergetic effect between process innovations, green and lean practices playing a crucial role towards the improvement of green supply chain performance. This paper presents an innovative approach since it studies simultaneously the three dimensions of sustainability (environmental, social and economic), the lean, the innovation process and green paradigms which are considered strategic for supply chain competitiveness. Investigation of the relationships between the four strategies is a contribution that the authors hope will become a forward step in the promotion of sustainability as a third dimension of the manufacturing supply chain, along with the efficiency and responsiveness dimensions
