从创新到多元化:一个简单的竞争模型

From innovation to diversification: a simple competitive model

Fabio Saracco, Riccardo Di Clemente, Andrea Gabrielli, Luciano Pietronero

摘要:

很少有人试图描述出口双边矩阵国家/产品的统计特征和历史演变。一个重要的观点是引入产品网络,即一个产品等级森林,模拟商品的形成和演变。在这篇文章中,我们提出了一个简单的动态模型,其中国家相互竞争,以获得生产和出口新产品的能力。各国将有两种可能扩大出口:创新,即引进新产品,即产品网络中的新节点,或复制他人的生产过程,即占据同一网络中已有的节点。通过这种方式,产品网络的拓扑结构和国家-产品矩阵在国家推动创新的驱动下同时演化。

英文摘要:

Few attempts have been proposed in order to describe the statistical features and historical evolution of the export bipartite matrix countries/products. An important standpoint is the introduction of a products network, namely a hierarchical forest of products that models the formation and the evolution of commodities. In the present article, we propose a simple dynamical model where countries compete with each other to acquire the ability to produce and export new products. Countries will have two possibilities to expand their export: innovating, i.e. introducing new goods, namely new nodes in the product networks, or copying the productive process of others, i.e. occupying a node already present in the same network. In this way, the topology of the products network and the country-product matrix evolve simultaneously, driven by the countries push toward innovation.
