【摘要】This paper proposes a new approach to measuring agglomeration economies in Japan. Under the proposed approach; we used the Solow residual to measure agglomeration economies and confirmed that agglomeration economies exist in both manufacturing and non-manufacturing industries. Furthermore; this paper shows that social overhead capital has a positive effect on agglomeration economies. Currently; agglomeration economies are robust only in metropolitan areas; however; they are present throughout Japan because of the disproportionate allocation of social overhead capital within the nation.
