Great changes and contradictions have occurred in the economy in recent years, forcing entrepreneurs to seek solutions to increase competitiveness, maintain growth and implement mechanisms that can create permanent solutions in the future, thus promoting development. In this context, the aim of this study is to investigate whether the perception of the entrepreneurial ecosystem is a significant predictor of the perception of competitiveness and sustainable development in the Peruvian case. For this, a structural equation model was tested using data obtained from a convenience sampling method (n = 240) along with a 32-item scale, which was adapted and validated using an exploratory factor analysis. Participants of this study were actors from the entrepreneurial ecosystem of the eastern cone of Lima, 79.1% of whom were entrepreneurs and businessmen (6.2% from the industrial sector, 50.5% from the commercial sector and 22.4% from the service sector); the remaining 20.9% of the sample corresponds to university professors, students, directors and advisors of incubators and accelerators. Findings of this study suggest that the perception of these actors of the entrepreneurial ecosystem has a significant effect on its perception of competitiveness and sustainable development.
