摘要翻译：
经济复杂性反映了一个经济体的生产结构中所包含的知识的数量。它以隐藏的能力为前提--生产结构背后的基本禀赋。一般说来，直接衡量经济复杂性背后的能力是困难的，有人建议采取间接措施，利用一个国家的产品组合来表示能力的存在这一事实。我们通过引入一个概率框架来补充这些研究，该框架利用贝叶斯非参数技术来提取出口产品比较优势背后的主导特征。基于经济证据和贸易数据，我们将一个受限制的印度自助餐过程置于国家能力禀赋的分布上，并借助一个烹饪隐喻来模拟能力获得的过程。该方法具有独特的可解释性，因为它产生了对实例化功能的简洁且经济合理的描述。

英文摘要：
Economic complexity reflects the amount of knowledge that is embedded in the productive structure of an economy. It resides on the premise of hidden capabilities - fundamental endowments underlying the productive structure. In general, measuring the capabilities behind economic complexity directly is difficult, and indirect measures have been suggested which exploit the fact that the presence of the capabilities is expressed in a country's mix of products. We complement these studies by introducing a probabilistic framework which leverages Bayesian non-parametric techniques to extract the dominant features behind the comparative advantage in exported products. Based on economic evidence and trade data, we place a restricted Indian Buffet Process on the distribution of countries' capability endowment, appealing to a culinary metaphor to model the process of capability acquisition. The approach comes with a unique level of interpretability, as it produces a concise and economically plausible description of the instantiated capabilities.
