| 中文摘要: |
| 运用综合比较优势指数、空间重心模型等方法对2005—2022年我国草莓产业竞争力及综合比较优势时空演变特征进行分析。结果显示：山东、辽宁、河北3省草莓产业效率优势明显，上海、浙江、辽宁、江苏、山东、河北6省市规模化程度高于全国平均水平，辽宁、上海、浙江、江苏、山东、河北6省市综合比较优势突出；2005—2022年我国草莓产业进步明显，优势区域有所扩大，劣势区逐步缩减；综合比较优势重心“前期波动，后期加速西进南移”；全局空间自相关指数(Moran’s I)介于0.301～0.439，呈现高度显著的空间集聚特征。结合我国草莓产业现状，提出相应的对策建议，以期提高我国草莓产业综合竞争力。 |

| Based on the theory of comparative advantage, this study analyzed the evolution of regional competitiveness and spatial layout of China’s strawberry industry from 2005 to 2022 using the comprehensive comparative advantage index, spatial gravity center model, and global Moran’s I index. The results indicate:(1) China’s strawberry cultivation area and yield have continued to grow, reaching 147,500 hectares and 3.9816 million tons in 2022, respectively. From 2005 to 2022, scale expansion dominated the growth.(2) The competitiveness pattern exhibits "multi-polar synergy": efficiency advantages shifted to the Qinghai-Tibet Plateau, scale advantages concentrated in eastern regions (Shandong, Jiangsu) and southwestern regions (Yunnan, Sichuan), while comprehensive advantages formed four major growth poles in northeastern (Liaoning), Qinghai-Tibet, and southwestern regions.(3) The spatial gravity center of strawberry production migrated southwestward from 2005 to 2022, undergoing three phases: fluctuation and adjustment, southwestern breakthrough, and northeastern mutation.(4) The global Moran’s I index averaged 0.099, indicating a "weak agglomeration fluctuation" in spatial distribution. Based on these findings, countermeasures are proposed to optimize the strawberry industry structure. |
