There are three conflicting views about the relationship between the level of specialization (or diversification) of industrial structure and its growth, namely, MAR externalities, Jacobs' externalities, and Porter's "Industrial cluster". This paper investigates which theory is most applicable to Japanese regional industries by using manufacturing industries' data. In the general machinery industry, which provides common technology to other industries, diversified agglomeration structure positively affects growth (supporting Jacobs' externalities.) However, specialized structure positively affects the growth in the other processing/assembling industries, especially electronics (supporting MAR externalities). Judging from the empirical results, it depends on the character of each industry which theory is applicable. Or, if we see spatial agglomeration of basic processing industries (like general machinery) with the growing industries as an "industrial cluster", the third view advocated by Porter is most applicable.
