英文文献摘要：
This paper examines empirically two distinguishing aspects of the world's wine regions: their degree of specialization in certain varieties, as measured by a varietal intensity index; and their similarity with the varietal mix of other regions, as measured by a varietal-based regional similarity index. Twelve of the most important wine-producing countries, that together account for all but one-eighth of the world's winegrapes, are included in the analysis. The data refer to circa 2000 (or 1999 for EU member countries, since that is their most recent census data). These indexes provide a baseline against which to compare more recent and future vintages. They will be especially useful as producers and regulators respond at varying speeds to the impacts of climate changes, in addition to market developments, on the optimal location of production of different varieties around the world.

本文从实证的角度考察了世界葡萄酒产区的两个不同方面:它们对某些品种的专业化程度，通过品种强度指数来衡量;以及它们与其他地区的品种组合的相似性，通过以品种为基础的区域相似性指数来衡量。该分析包括了12个最重要的葡萄酒生产国，这些国家的葡萄产量占全世界葡萄产量的1 / 8。这些数据大约是在2000年(对欧盟成员国来说是1999年，因为那是他们最近的人口普查数据)。这些索引为比较最近和未来的年份提供了一个基线。它们将特别有用，因为除了市场发展之外，生产者和监管者还以不同的速度应对气候变化对世界各地不同品种生产的最佳地点的影响。
