社会网络、风险识别能力与农村移民可持续生计——基于代际差异视角

Social Network,Risk Identification Capability and Sustainable Livelihood of Rural Migrants:Based on Perspective of Intergenerational Difference

将农村移民的风险识别能力作为中介变量,构建了"社会网络—风险识别能力—农村移民可持续生计"的理论模型。利用针对三峡库区农村移民的调研数据,研究了农村移民的社会网络对其可持续生计水平的影响以及风险识别能力的中介效应。结果显示:社会网络规模、社会网络密度、风险识别能力与三峡库区农村移民的可持续生计水平显著正相关;社会网络规模、社会网络密度和风险识别能力对两代农村移民可持续生计水平的影响存在较大的代际差异;风险识别能力在社会网络与农村移民可持续生计水平的关系中发挥中介效应。
