摘要
經濟 growth is associated with the diversification of 經濟 activities, which can be observed via the 演化 of product export baskets. Exporting a new product is dependent on having, and acquiring, a specific set of capabilities, making the diversification process path-dependent. Taking an agnostic view on the identity of the capabilities, here we derive a probabilistic model for the directed dynamical process of capability accumulation and product diversification of countries. Using international trade data, we identify the set of pre-existing products, the product Ecosystem, that enables a product to be exported competitively. We construct a directed 網絡 of products, the Eco Space, where the edge weight corresponds to capability overlap. We uncover a modular structure, and show that low- and midd
