The purpose is twofold: (i) to determine the extent to which companies' efforts aimed at sustainable business practices consider stakeholders in their organisations and business networks, the marketplace and society; and (ii) to validate or refute a stakeholder framework of business sustainability efforts within focal companies, the marketplace, society and business networks. Design/Methodology/Approach: Based on a questionnaire survey targeting large companies across industries and sectors in Spain. The sample consisted of 231 companies generating a useable response rate of 38.5%. Exploratory factor analyses was performed on a crossindustry sample to test a five-dimensional framework. Findings: Reports on the validation of initial and refined factor solutions. The factor analyses confirmed five stakeholder dimensions related to business sustainability efforts of organisations, their business networks, marketplace and society. The validated results indicate satisfactory convergent, discriminant and nomological validity and reliability through time and across contexts. Research implications: The stakeholder framework in connection to business sustainability efforts in supply chains consisting of five factors was validated: (i) the focal company, (ii) downstream stakeholders, (iii) societal stakeholders, (iv) market stakeholders, and (v) upstream stakeholders.. Suggestion for further research is provided. Managerial implications: The validated framework of stakeholders allows insight into the environment which stakeholders operate and how they influence on the focal company. Originality/Value: The manuscript contributes to the validation of a stakeholder framework of business sustainability efforts within focal companies, their business networks, the marketplace and society. The measurement properties provide support for acceptable validity and reliability across contexts and through time.
