We examine Chile, which represents a vibrant economy and one of the world's most productive entrepreneurship ecosystems but with a history of socio-economic inequalities and strong profit-driven pressures to overextract natural resources. The study is based on a questionnaire related to manufacturing sent to 112 companies in Chile. The proposed relationships are analysed through structural equation modelling. The results indicate that ILPs fully mediate the effect of entrepreneurial orientation on environmental performance and social performance and partially mediates the effect of entrepreneurial orientation on operational performance. Our study extends the literature by explaining that entrepreneurial orientation builds and strengthens ILPs for creating triple bottom line competitive advantage.15 p.enEntrepreneurial orientationInternal lean practicesSustainabilityTriple bottom lineArticle
