摘要:Based on social exchange theory, this research developed a theoretical model on the impact of the internal corporate social responsibility (ICSR) of platform enterprises on employee innovation performance. Based on 414 employee data from 56 platform enterprises, hierarchical linear modeling was employed to test the model at two time points. The results revealed that the ICSR of platform enterprises has a significant positive effect on employee innovation performance, and employee intrapreneurship mediates the relationship; that is, the ICSR of platform enterprises promotes employees’ innovation performance by stimulating their intrapreneurship. Employees’ moral identity can also positively moderate the relationship between the ICSR of platform enterprises and employee intrapreneurship; the stronger the employees’ moral identity is, the stronger the positive impact of the platform’s ICSR is on the employees’ intrapreneurship. The relationship between the ICSR and employee innovation performance was clarified under platform economics. The current conclusions can guide platform enterprises’ innovation and sustainable development efforts.
