【摘要】This study employs a rich set of disaggregated manufacturing industry data to estimate density gradients for five metropolitan areas over the time span 1967–1971. The results are consistent with both expectations and with a number of other studies of industry location. More importantly, however, this study examines many of the methodological problems associated with the density gradient. It is concluded that the density gradient has reached the point of diminishing returns as a tool of the urban economist.
