论文摘要
我们的目的是通过提出当前文献的许多扩展来为产品空间和多元化的文献做出贡献：（1）我们建议，乡村空间的替代性但相关的思想也具有经验和理论上的吸引力； （2）我们认为，比较优势的丧失应该是产品空间思想的（测试经验相关性）的组成部分； （3）我们提出了几个新指标，以衡量产品空间中的相关性； （4）我们提出了基于自举的非参数统计检验，以测试产品空间思想的经验相关性。
We aim to contribute to the literature on product space and diversification by proposing a number of extensions of the current literature: (1) we propose that the alternative but related idea of a country space also has empirical and theoretical appeal; (2) we argue that the loss of comparative advantage should be an integral part of (testing the empirical relevance of) the product space idea; (3) we propose several new indicators for measuring relatedness in product space; and (4) we propose a non-parametric statistical test based on bootstrapping to test the empirical relevance of the product space idea.
