摘要翻译：
经济增长是通过升级他们生产和出口的产品类型来实现的。制造这种新产品所需的技术、资本、机构和技能比其他产品更容易从某些产品中适应。我们研究了产品之间的关系网络，即产品空间，发现大多数高档产品位于紧密连接的核心，而低收入产品位于联系较少的外围。我们表明，各国倾向于转向与它们目前专门从事的产品相近的产品，这使得位于产品空间中联系更紧密的部分的国家能够更快地升级其出口篮子。大多数国家只有在产品空间中跨越经验上不常见的距离，才能到达核心。这可能有助于解释为什么贫穷国家难以发展更具竞争力的出口，无法与富裕国家的收入水平趋同。

英文摘要：
Economies grow by upgrading the type of products they produce and export. The technology, capital, institutions and skills needed to make such new products are more easily adapted from some products than others. We study the network of relatedness between products, or product space, finding that most upscale products are located in a densely connected core while lower income products occupy a less connected periphery. We show that countries tend to move to goods close to those they are currently specialized in, allowing nations located in more connected parts of the product space to upgrade their exports basket more quickly. Most countries can reach the core only if they jump over empirically infrequent distances in the product space. This may help explain why poor countries have trouble developing more competitive exports, failing to converge to the income levels of rich countries.
