英文摘要：
  Evaluating the economies of countries and their relations with products in the global market is a central problem in economics, with far-reaching implications to our theoretical understanding of the international trade as well as to practical applications, such as policy making and financial investment planning. The recent Economic Complexity approach aims to quantify the competitiveness of countries and the quality of the exported products based on the empirical observation that the most competitive countries have diversified exports, whereas developing countries only export few low quality products -- typically those exported by many other countries. Two different metrics, Fitness-Complexity and the Method of Reflections, have been proposed to measure country and product score in the Economic Complexity framework. We use international trade data and a recent ranking evaluation measure to quantitatively compare the ability of the two metrics to rank countries and products according to their importance in the network. The results show that the Fitness-Complexity metric outperforms the Method of Reflections in both the ranking of products and the ranking of countries. We also investigate a Generalization of the Fitness-Complexity metric and show that it can produce improved rankings provided that the input data are reliable.

中文摘要：
评估各国经济及其与全球市场产品的关系是经济学的一个核心问题，对我们对国际贸易的理论理解以及政策制定和金融投资规划等实际应用具有深远影响。最近的经济复杂性方法旨在量化各国的竞争力和出口产品的质量，其依据是经验观察结果，即最具竞争力的国家出口多样化，而发展中国家只出口很少的低质量产品——通常是许多其他国家出口的产品。在经济复杂性框架下，提出了两种不同的度量标准，即适应度复杂度和反映方法来衡量国家和产品得分。我们使用国际贸易数据和最近的排名评估指标，定量比较这两个指标根据国家和产品在网络中的重要性对其进行排名的能力。结果表明，适应度复杂度指标在产品排名和国家排名中均优于反映法。我们还研究了适应度复杂性度量的一个推广，并表明只要输入数据可靠，它可以产生更好的排名。
