E-commerce platforms (e.g., Amazon and Alibaba) are trying new approaches to incentivize CSR efforts among their suppliers. This paper challenges the common belief that the financing services provided by e-commerce platforms can help capitalconstrained suppliers improve their Corporate Social Responsibility (CSR) performance. Using a Stackelberg game approach, we demonstrate that the application of platform financing services can simultaneously achieve the following objectives: (i) improve CSR performance; (ii) enhance total channel profits; (iii) ensure that each partner in the channel can benefit from the financing service. Overall, our results provide insights into when and how to adopt financing services in order to achieve operational objectives, attain higher profits, and enhance CSR performance.
