Citation analysis is a bibliometric method using reference citations found in scientific papers as the primary analytical tool. This paper attempts to clarify the communication network of one field in geography by means of citation analysis. Central place studies, originating from Christaller and Lösch, are selected for this purpose.Citation is taken to represent four indicators as follows: 1) quality, 2) recognition, 3) diffusion and communication network, and 4) utilization. First, this paper reviews various measures used in citation analysis, such as bibliographic coupling, link connection, and co-citation, which have developed in the fields of Sociology of Science, and Library and Information Science. Multivariate data analyses, especially cluster analysis, factor analysis and multidimensional scaling (MDS), make it possible to deal with a large number of citation data such as the Scientific Citation Index (SCI) and the Social Sciences Citation Index (SSCI).Second, citation analysis used in the field of geography is reviewed (see Table 1). According to the indicators mentioned above, the studies are divided into three categories: 1) quality of research, productivity and ranking, 2) professional recognition and reward, and 3) communication network and diffusion of ideas.Third, to examine the communication network of geographers, the early central place studies are considered. In the present study, the citation frequency of 98 papers by 57 geographers which are taken from “Central Place Studies” (Berry and Pred, 1965) are counted directly, and an asymmetric matrix (57×57) is constructed. Citation frequencies are transformed into “distance”; hence the distance between geographers is analyzed by MDS, which assigns relative locations in two-dimensional space: the scaled configuration of highly cited and co-cited geographers would be a concrete representation of the communication network. It is expected that the 57 geographers comprise subgroups based on nationality, specialty and/or school.In the present study, seven clusters are identified: 1) the Lund school, 2) the Chicago school, 3) the Washington school and researchers with theoretical and quantitative approaches, 4) English researchers, 5) CBD researchers, 6) researchers concentrating on the internal business structure of the city, and 7) marketing researchers (see Fig. 4).As a result, reference space fundamentally consists of two axes: “quantitative analysis vs. qualitative description” and “European geographers vs. American geographers”. When properly used, citation analysis can introduce a useful and effective measure of objectivity into the classification and evaluation of science and recover a communication network among researchers.
