This study focuses on local agglomeration effects on productivity, in which the spatial size-distribution of firms is taken into consideration. The data set is comprised of four-digit firm level data on Japanese manufactures for 2005. The estimation by use of firm data enables us to identify various agglomeration effects. The estimation model is based upon the stochastic frontier (labour) production function approach, in which we examine what type of local agglomeration contributes to improve productive efficiency. The estimation results suggest that for most light industries agglomeration of various sizes of firms is important for productivity rather than the concentration of uniform small size firms.
