英文摘要：
We introduce an algorithm able to reconstruct the relevant network structure on which the time evolution of country-product bipartite networks takes place. The significant links are obtained by selecting the largest values of the projected matrix. We first perform a number of tests of this filtering procedure on synthetic cases and a toy model. Then we analyze the bipartite network constituted by countries and exported products, using two databases for a total of almost 50 years. It is then possible to build a hierarchically directed network, in which the taxonomy of products emerges in a natural way. We study the influence of the structure of this taxonomy network on countries\' development; in particular, guided by an example taken from the industrialization of South Korea, we link the structure of the taxonomy network to the empirical temporal connections between product activations, finding that the most relevant edges for countries\' development are the ones suggested by our network. These results suggest paths in the product space which are easier to achieve, and so can drive countries\' policies in the industrialization process.

中文摘要：
我们介绍了一种算法，该算法能够重建相关的网络结构，在该结构上国家产品二部网络发生时间演化。通过选择投影矩阵的最大值来获得有效链接。我们首先在合成案例和一个玩具模型上对这个过滤过程进行了大量测试。然后，我们分析了由国家和出口产品构成的双边网络，使用了两个数据库，历时近50年。这样就有可能建立一个分层定向的网络，其中产品的分类以一种自然的方式出现。我们研究这个分类网络的结构对国家发展的影响；特别是，以韩国工业化为例，我们将分类网络的结构与产品激活之间的经验性时间联系联系起来，发现与国家发展最相关的优势是我们的网络所建议的优势。这些结果表明，产品领域的路径更容易实现，因此可以推动各国工业化进程中的政策。
