This is the fifth chapter of a six chapter report which discusses Chinese research and education in solid state physics, and their relations to technology and the other sciences. This specific chapter concerns the communication of information in the scientific community and the transfer of information to students and practical users (manufacturers). The number of different modes of communication (formal/informal, written/oral) and the number of channels are essentially uninfluenced by international boundaries. However, the roles and characteristics of these channels are quite different in China because of differing goals, conditions, and historical backgrounds. A brief narrative appraisal is provided on the following channels: exchange of personnel, seminars, conferences, research journals, reports, travel and publication outside China, and libraries. The transfer of technology from research to production mainly involves personal contacts rather than reports and publications. The student- faculty groups at factories, student instruction at universities, and university staff product developments bear directly on the transfer of research to factory production. The dependence on person to person contacts for technology transfer works well given the relatively small scientific and technical establishments, and the small amount of information transfer between specialties.
