Humans cultivate thousands of economic plants (i.e. plants with economic value) outside their native ranges. To analyze how this contributes to naturalization success, we combine global databases on economic uses and naturalization success of the world's seed plants. Here we show that naturalization likelihood is 18 times higher for economic than non-economic plants. Naturalization success is highest for plants grown as animal food or for environmental uses (e.g. ornamentals), and increases with number of uses. Taxa from the Northern Hemisphere are disproportionately over-represented among economic plants, and economic plants from Asia have the greatest naturalization success. In regional naturalized floras, the percentage of economic plants exceeds the global percentage and increases towards the equator. Phylogenetic patterns in the naturalized flora partly result from phylogenetic patterns in the plants we cultivate. Our study illustrates that accounting for the intentional introduction of economic plants is key to unravelling drivers of plant naturalization.
人类在其原生范围之外种植了数千种经济植物（即具有经济价值的植物）。为了分析这如何有助于自然归化的成功，我们结合了全球关于经济用途和世界种子植物自然归化成功率的数据库。在这里，我们发现经济植物的自然归化可能性比非经济植物高 18 倍。作为动物食物或用于环境用途（例如观赏植物）的植物自然归化成功率最高，而且随着用途数量的增加而增加。来自北半球的分类群在经济植物中过度代表，而来自亚洲的经济植物具有最大的自然归化成功率。在区域归化植物群中，经济植物的百分比超过全球百分比，并向赤道方向增加。归化植物群中的系统发育模式部分是由我们所栽培的植物的系统发育模式造成的。我们的研究表明，考虑到经济植物的有意引入是揭示植物自然归化驱动因素的关键。
