RT Journal Article T1 Exploring the Effects of Innovation Strategies and Size on Manufacturing Firms’ Productivity and Environmental Impact A1 Seclen Luna, Jean Pierre A1 Moya Fernández, Pablo A1 Pereira Sánchez, María Ángeles K1 Innovation strategies K1 Productivity K1 Environmental impact K1 Manufacturing K1 Size AB In economies that are based on natural resources, efforts to achieve sustainability still seem unclear, especially in manufacturing companies. As a result, from a business perspective, many manufacturers have adopted various strategies to maintain their competitiveness in line with environmental regulations. In addition to product and process innovation, we have analyzed innovation based on product–service innovation (PSI), or servitization, which is seen as key to promoting more resource-efficient economies. This study examines the effects of innovation strategies on productivity and environmental impact. Based on data extracted from the National Innovation Survey of the manufacturing industries of Peru, a sample of 791 companies were analyzed. Our findings indicate that, although only a few companies carry out product and process innovation and especially product–service innovation, when they do, they have a positive effect on both productivity and environmental impact. However, this relationship is affected by the size of the company. Thus, the innovation strategies have a greater positive effect on environmental impact in large companies than companies with fewer than 50 employees. Finally, despite the importance of product–service innovation, it seems that this strategy is not yet established in Peruvian manufacturing companies. Given the positive effect on productivity and environmental impact, we conclude by emphasizing the importance of establishing public policies aimed at disseminating and promoting this type of innovation, with specific support for companies with fewer than 50 employees PB MDPI YR 2021 FD 2021 LK http://hdl.handle.net/10347/24799 UL http://hdl.handle.net/10347/24799 LA eng NO Sustainability 2021, 13(6), 3289; https://doi.org/10.3390/su13063289 DS Minerva RD 27 abr 2026
