We adapt the product-space approach of Hausmann–Hidalgo et al. to the case of Italian provinces, examining the extent to which network connectedness and centrality of a province’s exports is related to its economic performance. We construct a new Product Space Position (PSP) index which retains many of the Hausmann–Hidalgo et al. features but which is also much better suited to handling regional and provincial data. The PSP index is found to outperform other indices. Our comparison throws light on fundamental aspects of network-cognitive-distance-trade arguments. A better positioning in the export-network product space is indeed associated with better local economic outcomes.

促进区域增长和创新：相关性、显性比较优势和产品空间

我们采用 Hausmann-Hidalgo 等人的产品空间方法。以意大利各省为例，研究一个省出口的网络连通性和中心性与其经济表现相关的程度。我们构建了一个新的产品空间位置 (PSP) 指数，该指数保留了 Hausmann-Hidalgo 等人的许多内容。功能，但也更适合处理区域和省级数据。发现 PSP 指数的表现优于其他指数。我们的比较揭示了网络认知距离交易论点的基本方面。在出口网络产品领域的更好定位确实与更好的当地经济成果有关。
