农户生计资本的影响因素具有空间非平稳性,因此一般以“平稳性假设嵌入”为基础的普通线性回归模型对农户生计资本影响因素空间差异分析的精确性不高。本文应用地理加权(GWR)回归模型对上海市青浦区182个行政村进行农户生计资本总量的空间分析及其影响因素的空间分异特征研究。结果表明:2014年青浦区各行政村农户生计资本总量和类型分布呈现明显的空间分异规律,生计资本总量在空间上由西向东逐渐递增;其中,农业生计资本类型由西向东逐渐减少,非农类型则由东部向西逐渐减少;经济发展因素和社会发展因素对行政村农户生计资本总量影响强于自然地理空间因素,其中与生计资本变化呈正相关的因素依次为...

The factors affecting livelihood capital are non-stationary; therefore, a general linear regression model based on the assumption of＇ stationary hypothesis embedding＇ is not accurate for the analysis of these factors for farmers. Here, the method of aggregative indicator was used to calculate the total livelihood capital of administrative villages in Qingpu District, then to cluster. We adopted an ordinary least square model （OLS）and geographic weighted regression model （GWR） to examine the spatial differentiation of factors affecting the...
