农民工社会资本对其健康状况的影响研究——兼论维度差异与城乡差异

The Impact of Social Capital on the Health Status of Rural- urban Migrant Workers

本文将社会资本理论纳入Grossman健康需求框架,通过划分农民工社会资本城乡类型和维度结构,分析了农民工社会资本影响其健康的维度差异和类型差异,并基于2014年浙江省样本数据,通过IV-Probit模型和泊松回归等方法对研究假设进行了实证检验。研究表明,农民工社会资本存在健康促进效应,相对代表认知型社会资本的信任和互惠而言,代表结构型社会资本的社会网络对农民工健康具有更强的促进作用,而城镇型社会资本对农民工健康的促进效应大于乡村型社会资本。相关结论对于破解农民工健康困境、城镇化道路选择以及理解非正式制度与正式制度的关系具有一定启示。
