本文以生态脆弱群体的就医偏好与决策行为为研究对象,运用问卷调查和访谈,从生态脆弱群体的属性特征和社会因素两个方面,构建logistic回归模型,分析生态脆弱群体就医偏好与决策行为。从回归模型的整体拟合来看,自变量与各别因变量之间存在显著的线性关系,其渐进Sig.(双侧)值均小于0.05。其中:生态脆弱群体的教育程度、经济和身体状况等属性特征与生态脆弱群体的就医偏好存在显著线性关系;社会因素中医疗服务满意程度、医疗条件的优劣、就医程序复杂程度与生态脆弱群体的就医决策行为存在显著线性关系。据此,形成了两种类型的就医行为模式,即"自养"和"异养"型模式。研究结果可为生态脆弱群体就医行为类型的划分提供借鉴,促进行为地理学和健康地理学的融合研究。

At present, China is growing to be one of the biggest and fastest economies of the world and Chinese cities actually have accounted for most of the growth. With the rapid development of Chinese cities, more and more rural migrants crowd into cities and bring about various urban development issues related with housing, work, transit, and medical care etc. The ecological vulnerable groups, mainly the rural migrants and the urban low-income, in turn, response to these coupled changes through their daily living activities like medical care that this study focus on. Their medical behaviors can be looked on as the positive feedback to external influences. Accordingly, this paper aims to disclose the ecological vulnerable groups' medical treatment preference and decision, taking Xi'an as a case, which is a rapid growing city with a long history in China and a big population in northwestern China. Based on data from random questionnaires and deep interviews on the ecological vulnerable groups in Xi'an collected during the summer of the year 2011, regression model of Logistic is established from the ecological vulnerable groups' attributes and social factors. Among all the social factors, there is an obvious linear relationship between satisfactory degree for medical service, superiority or inferiority of medical conditions and complexity of the medical procedures with the ecological vulnerable groups' medical decision-making behavior. Finally, two types of medical behavior patterns are defined as the "autotrophic" and the "heterotrophic", which are concepts learned from ecology.
