摘　　要：本文发展了一种改进的产业结构相似度测度方法——产业结构相似指数,该指标具有一般性,改进克鲁格曼指数是其在2地区模型的一个特例。研究发现,在用于多地区模型时,研究者容易掉入产业结构相似系数、改进克鲁格曼指数等指标的"用法陷阱"。对这些指标予以两种方式的灵活应用,则可避免掉入"用法陷阱"。本文还发现,在讨论区域分工问题时,地区的相对规模因素具有重要的影响;如果忽略城市的相对规模因素,则会高估长江三角洲地区工业分工水平。In this paper, we constitute Industrial Structure Similarity Index, an improved indicator to measure industrial structure similarity degree between areas. It is a more generalized indicator as Improved Krugman Index which is a special form of 2-region model. We find that researchers easily fall into the ＂Usage trap＂ when applying such indicators as Industrial Structure Similarity Coefficient and Improved Krugman Index to multi-region model. There are two ways to avoid falling into the ＂Usage trap＂. We also find that the relative size of the region has an important impact on the level of regional division of labor. And we will overestimate the level of industrial division of labor in Yangtze Delta Area without taking into account the impact of the relative size of the city.
