社会保障制度是伴随生产社会化和市场经济的形成建立起来的，它对发展经济、稳定社会具有重要作用。分析社会保障水平现状及影响因素，对于社会保障制度的发展完善具有重要意义。以山西省为例，选取12个与社会保障水平相关的指标，通过因子分析，构建评价体系，最终得到一项综合指数用来衡量社会保障水平，然后搜集山西省2000~2016年的宏观指标作为样本数据，运用计量经济学理论，建立了相关的多元线性回归模型，分析影响山西省社会保障水平的重要因素。研究结果表明：失业率、财政社会保障支出对社会保障水平的影响较为显著。最后，围绕山西省社会保障水平存在的问题提出建议，主要有：从长期来看，要推进经济发展，提高社会保障水平；现阶段要扩大社会保障基金来源，优化支出结构。
