贸易数据往往按产品特点分类。我们提出了一个新的分类“复杂性”，作为区分产品的一种手段。本文根据出口经济的收入水平构建了一个复杂度指数。复杂性涵盖了一系列因素，包括技术、产品碎片化的难易程度、自然资源的可用性和营销。我们计算3位数和4位数水平的复杂度得分，并测试该指数与现有产品技术分类的相关程度。我们使用该指数来检查贸易模式，并说明如何将其应用于分析单个经济体的出口绩效。(c)2005爱思唯尔有限公司保留所有权利。
Trade data are often classified by product characteristics. We propose a new classification "sophistication" as a means of distinguishing between products. We construct a sophistication index based on the income levels of exporting economics. Sophistication captures a range of factors including technology, ease of product fragmentation, natural resource availability, and marketing. We calculate sophistication scores at the 3- and 4-digit levels and test how far the index relates to existing technological classifications of products. We use the index to examine trade patterns and illustrate how it can be applied in the analysis of export performance of individual economics. (c) 2005 Elsevier Ltd. All rights reserved.
