Localization of Industry and Vertical Disintegration
理论认为产业本地化程度越高，垂直解体越明显。本文用美国制造业数据验证了这一推论，以购买投入占产出价值比衡量垂直解体，用同行业邻近工厂就业量衡量本地化。
Theory suggests that vertical disintegration should be greater in areas where industries localize. This paper provides some evidence that this implication is true for the U.S. manufacturing sector. Purchased inputs as a percent of the value of output is used as a measure of vertical disintegration. To measure the localization of industry, for each manufacturing plant the amount of employment in neighboring plants in the same industry is determined. © 1999 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
