Hello! I am preparing a University of Bologna Sustainable Business course project about Xiaomi as a technology ecosystem company and its relationship with sustainability, ESG, product life cycle, circular economy, and responsible innovation. This questionnaire is anonymous and only for academic coursework. It does not ask for confidential company information, names, departments, contact details, or other sensitive personal information. Please answer based on your own observations and honest feelings. It should take about 3–5 minutes. Thank you very much!
