Abstract: A research and development system and method are provided. The research and development system includes a cloud service sub-system and a cloud research and development sub-system in communicative connection with each other. The cloud service sub-system is configured to manage project information related to a target project. The cloud research and development sub-system is deployed with a cloud development environment and cloud development software, and is configured to acquire target project information in the project information from the cloud service sub-system, provide usage permission of the cloud development environment and corresponding cloud development software, and transmit, to the cloud service sub-system, a project file generated according to the target project information, so as to perform research and development on the target project.
