How open innovation can improve companies' corporate social responsibility performance?

Open Innovation (OI) allows companies to develop innovative solutions more effectively, with lower costs and risks. The economic benefits of OI have been thoroughly investigated in prior research. More recent literature suggests that OI can help companies also improve their Corporate Social Responsibility (CSR) performance. Contributions on how open innovation can help companies improve their CSR performance, however, are fragmented and lack strong theoretical foundations. In this study, we perform a systematic literature review to synthesize the main findings and provide a theoretical framework to explain how companies can simultaneously improve OI and CSR through the management of relationships with stakeholders. The framework is then used to investigate how OI projects favour the achievement of CSR objectives, by referencing the 17 United Nations (UN) Sustainable Development Goals (SDGs). Results show that the stakeholders' theory can be used to explain the connection between OI and CSR performance. We also find that companies can collaborate with different stakeholders' categories to achieve a variety of CSR goals. We suggest that companies adopt a long‐term perspective and explicitly include sustainability objectives in their open innovation strategy to enhance their position as reliable partners and elicit favourable responses from the environment. Results also allow us to provide some suggestions for future research. First, we point out that literature currently lacks conceptual studies to help formalize the connection between OI and CSR. Secondly, we observe that the influence of some stakeholders' categories, such as governments and research organizations, on companies' OI and CSR efforts remains under‐investigated.
