This paper measures the strength, direction, scope and pattern of the economic ties of American snow sports through the comprehensive use of gravity model, social network analysis and nuclear density analysis, so as to clarify the spatial characteristics of the economic ties of American snow sports, with a view to summing up its reference significance to China. The results show that the economic connection intensity of snow sports in the United States shows a decreasing pattern from east to west to middle. The economic connection direction of snow sports in the United States has regional proximity, economic development level, snow resource abundance and population size. The economic connection range of snow sports is distributed in four major ranges, and the radiation capacity is gradually decreasing from northeast to central to south to west. The economic connection pattern of snow sports in the United States is distinct, showing four vertical subgroups from east to west. Based on the development experience of snow sports in the United States and the current situation of China, the following suggestions are put forward. Based on resource advantages, fully radiate the vitality of the ski industry; taking economic development as the engine, innovate and tap the potential of skiing industry; guided by resource integration, give play to the regional synergy effect of skiing industry; guided by the leading effect, build four high-quality skating industry development zones in the east, west, north and south.

综合运用引力模型、社会网络分析法和核密度分析法, 测度美国雪上运动经济联系的强度、方向、范围和格局等, 明晰美国雪上运动经济联系的空间特征, 总结其对中国的借鉴意义。研究结果表明, 美国雪上运动的经济联系具有如下特征: 1) 经济联系的强度空间上呈现东–西–中递减格局; 2) 经济联系的方向具有地域邻近性以及经济发展水平、积雪资源丰度和人口规模的指向性; 3) 经济联系呈四大范围分布格局, 辐射能力呈现东北–中部–南部–西部逐级递减格局; 4) 经济联系格局层次鲜明, 呈现从东到西竖条状的四大子群。基于美国雪上运动的发展经验, 立足中国现状, 提出如下建议: 以资源优势为基础, 充分焕发滑雪产业的活力; 以经济发展为引擎, 创新挖掘滑雪产业的潜力; 以资源整合为导向, 发挥滑雪产业区域协同联动效应; 以龙头效应为引领, 构建东西南北四大高质量滑产业发展区。
