Abstract: The representative work of Mr. Zhao Hong-zhou, namely An Introduction to the Study of Social Capacity for Science, was the integration of his ten years hard work exploring in the frontier of the study of social capacity for science since he devoted himself to the research in science of science. This achievement not only embodied the valuable exploration he had ever made in constructing the framework of that subdiscipline, but also drove many newborn subdisciplines in science of science foreward, such as scientometrics and the science of scientists.
