AI总结:

本文提出算法重建国家-产品双网络结构,分析产品分类对国家发展的影响,通过案例研究发现分类网络结构影响产品激活的时间连接,从而驱动国家政策。

摘要:

我们介绍一种算法,能够重建相关网络结构,该结构决定了国家-产品双网络随时间演变的机制。通过在合成案例和玩具模型上测试过滤程序,我们分析了由国家和出口产品构成的双网络,使用两个数据库覆盖近50年。由此可以构建一个分层有向网络,其中产品分类自然显现。我们研究了此类分类网络结构对国家发展的影响,特别是以韩国工业化为例,发现分类网络结构与产品激活的实证时间连接相关,最相关的边由我们的网络建议。这些结果表明产品空间中更容易实现的路径,从而推动国家工业化政策。

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.
