| Research Abstract |
we examine the existence of agglomeration economies on production in the Japanese manufacturing industries from 1980 to 2000 using plant-level 4-digit sub classification, panel dataset and new agglomeration index in Tokunaga and Akune (2005), and Tokunaga, Kageyama, and Akune (2005), based on Ellison and Glaeser (1997). This is an improvement on the conventional indices such as Location Quotient or Location Gini Coefficient. When we apply a flexible translog production function and cost share equation as suggested by Kim (1992), we find that around 1.5% of positive agglomeration effect exists in absence of any restriction on homotheticity in the case of employment based agglomeration (γ_<EG>) and the case of value added based agglomeration (γ_<EG>^V). On the other hand, we examine the existence of agglomeration and co-agglomeration effect on production in the Japanese industry from 1985 to 2000 using panel data of city-level 2-digit sub classification, panel dataset, agglomeration index in Henderson (2003), and co-agglomeration index in Ellison and Glaeser (1997). Using the Cobb-Douglas production function based on Nakamura and Eshima (2004), we found that a positive agglomeration and co-agglomeration effect and scale economies in the Japanese industry.
