| 核桃作为中国重要的木本油料作物，其生产格局的空间演变对产业配置效率提升及区域协调发展具有重大影响，但目前学界对核桃生产集中化水平的长时序、全国-区域-省域三层次的系统性分析相对较少。旨在为优化核桃产业区域资源配置、制定差异化产业政策提供扎实的实证依据，以2000—2024年省级核桃产量面板数据为基础，借助空间洛伦兹曲线引申出的生产集中化指数，对中国核桃生产空间省际集聚趋势及区域格局变动进行分析。结果表明：全国核桃生产集中化指数从2000年的69.85%上升到2024年的81.87%，增长12.02百分点，核桃产业进一步向优势区域及省（区、市）集聚；核桃生产重心空间布局持续西移，西南、西北地区核桃产量占比分别提高1053、16.32百分点，二者已成为新的核心增长极；新疆、云南、四川三省（区）核桃产量累计占比从2000—2005年的39.63%增至2021—2024年的66.55%。集体林权制度改革、脱贫攻坚政策及东西部协作机制等因素协同推进核桃生产向西部地区集聚，建议强化西部优势产区的战略地位，引导产区差异化协同发展，强化品牌引领与市场开拓，因地制宜发展新质生产力，推动我国从核桃生产大国向核桃产业强国的转变。 |

| Walnut, as an important woody oil crop in China, the spatial evolution of its production patterns has a significant impact on improving industrial allocation efficiency and promoting coordinated regional development. However, systematic analysis of the long-term of walnut production concentration across national, regional, and provincial levels are relatively scarce in current academic research. To provide a solid empirical basis for optimizing the allocation of regional resources in the walnut industry and formulating differentiated industrial policies, based on panel data on provincial walnut production from 2000 to 2024, using the production concentration index derived from the spatial Lorenz curve, a spatial analysis was conducted on the inter-provincial agglomeration trends and regional pattern changes of walnut production in China. The results showed that the national walnut production concentration index rose from 69.85% in 2000 to 81.87% in 2024, with an increase of 12.02 percentage points, the walnut industry was further concentrating in regions and provinces with comparative advantages. The spatial distribution of walnut production continued to shift westward, with the share of walnut production in the Southwest and Northwest regions increasing by 10.53 and 16.32 percentage points, respectively, making these two regions as the new core growth poles. The combined share of walnut production from Xinjiang, Yunnan, and Sichuan increased from 39.63% in 2000-2005 to 66.55% in 2021-2024. Factors such as the reform of the collective forest tenure system, poverty alleviation policies, and the East-West cooperation mechanism have collectively driven the concentration of walnut production in western regions. It is recommended to strengthen the strategic position of key production areas in the west, guide differentiated and coordinated development across these regions, enhance brand leadership and market expansion, develop new forms of productive capacity tailored to local conditions, and promote China′s transition from a major walnut producer to a leading industrial power. |
