中文摘要：

运用核密度估计和空间分布均衡度相关分析方法，分析了沈阳市大型连锁超市的空间分布和集聚特征，引入多元回归分析法进一步探析了其空间分异的影响因素和各因子的重要程度。结果表明，沈阳市大型连锁超市整体上呈现出“北多南少”的空间差异分布；核密度空间分布总体表现为二环内区域大面积组团状的核分布与二环以外地区小面积的零星核分布并存；在研究区域内呈现空间集聚分布特征，但在各个市辖区内分布不均衡；空间分异主要受等级公路密度、人口密度、城镇居民人均可支配收入、家庭户户数等因素的影响。

英文摘要：

This paper made an analysis to explore the spatial distribution and clustering of big chains in Shenyang City by using many methods such as kernel density estimation, equilibrium degree analysis. And this paper introduced the method of multiple regression analysis in order to further explore the elements of spatial differentiation and the degree of importance of each factor. The result showed ： Big chains in Shenyang City presented unevenly distributed in general, south - north differences of the spatial distribution was clear, which was showed that had large kernel areas within second ring road and small kernel areas outside, big chains in Shenyang City presented obvious characteristic of spatial distribution but it was not balanced in all urban areas, the factors were mainly grade highway density, population density, urban percapita disposable income and the number of households.
