抄録

The proportion of the numbers of the branch establishments controlled by external head offices to total establishments in each prefecture is about 15% on an average, and higher in the prefectures in Tohoku, Hokuriku, Sanin and Kyushu Districts (Fig. 1 a). The majority of their head offices are situtated at Tokyo and Osaka, and some are concentrated in Miyagi, Aichi, Hiroshima, Kagawa and Fukuoka Prefectures (Fig. 2). But only a few head offices are found in their neighbouring prefectures.
The industrial groups with many branches are areally monopolistic industries such as electricity and gas supply (67.6%), finance and insurance (49.4%), mining (36.4%) and transportation (21.6%) (Table 1).
Distributional pattern of the workers in the branch establishments is similar to that of the branch establishments, with the proportion of 25.4% to total workers in each prefecture on an average. The higher ratio means that the branch establishments are larger in scale than the establishments of local firms, in general. Therefore, the influence spheres of branch establishments seems to be larger than expected from the numbers of branch establishments in each prefecture.
