With the human resources data file on sociologists and social work academics furnished by the National Science Council, this paper provides a summary discussion on the academic development and research production in the fields of sociology and social work in Taiwan after the 2nd World War up to the year 1994. It is found that since social work has been defined as a practice discipline, instead of an academic discipline, the research production of social work academics have been relatively poor compared to the sociologists. In addition to the disciplinary differences, substantial differentiation in productivity with respect to sex, academic degree and position are also documented here. In average, sociologists with Ph. D. degree appear to be more productive than those without, males are more productive than the female, and professors have accumulated more academic publications than the junior sociologists. The differentials in the field of social work reveal a totally different story, however. The male professors of social work appear to be substantially less productive than the female counterpart, and males with Ph. D. degree are also less productive than those without. Based upon a cross-classification of the 736 journal articles and monographs published by the 109 sociologists, 9 categories of publication areas and self-stated research specialties have been identified by stressing the consistency between the areas and specialties. The 9 broad categories ranked by the person-year average productivity are social psychology, demography and ecology, social organization and stratification, political economy and social change, family and women studies, social welfare, social theories and social thoughts, others, culture and religion. A great degree of cross-boundary association are documented, albeit the emphasis on consistency in classification. It seems only natural that with a small community size, individual sociologists must develop diversified interests to fulfill the requirements of teaching and research. 67% of the articles and monographs published are in areas other than the self-stated specialties. Further analyses indicate that social psychologists are the most dedicated to specialty group among the sociologists, followed by the sociologists specialized in demography and ecology, social theories and social thoughts, family and women studies, social organization and stratification, political economy and social change, social welfare, others, culture and religion. It is determined that the academic productivity is positively related (r = 0.66) to the focus on specialty.
