分析我国电子商务运营效率的影响因素,探究提升我国电子商务运营效率的组合效应及互动关系。本文运用数据包络分析(DEA)测度我国2022年31个省份电子商务运营效率,运用模糊集定性比较分析(fsQCA)从组态视角分析电子商务运营高效率和非高效率的具体路径。我国2022年31个省份电子商务运营综合效率均值为0.425,共有5个省份达到DEA有效。实现电子商务运营高效率有2条路径,总体一致性为0.976,总体覆盖度为0.618。影响我国电子商务运营效率存在多重复杂因素,其中经济发展水平和人力资源禀赋为关键因素,多重条件协同作用提升我国电子商务运营效率,为辐射带动电子商务产业发展,加强供应链、产业链数字化提供参考。This paper aims to analyse the allocation efficiency of Chinese medical resources in China and explore the path to improve the allocation efficiency of Chinese medical resources in China. Data Envelopment Analysis (DEA) is used to measure the efficiency of e-commerce operation in 31 provinces in China in 2022, and Fuzzy Set Qualitative Comparative Analysis (fsQCA) is used to analyse the specific paths of e-commerce operation with high efficiency and inefficiency from the group perspective. The average value of comprehensive efficiency of e-commerce operation in 31 provinces in China in 2022 is 0.425, and a total of 5 provinces achieve DEA effectiveness. There are 2 paths to achieve high efficiency of e-commerce operations, with an overall consistency of 0.976 and an overall coverage of 0.618. Multiple complex factors affect the operational efficiency of e-commerce in China, among which the level of economic development and human resource endowment are the key ones. The synergistic effect of these multiple conditions enhances the operational efficiency of e-commerce in China, providing a reference for radiating and driving the development of the e-commerce industry and strengthening the digitization of supply chains and industrial chains.

目的探索基于IMB模型的同伴教育在老年人艾滋病高危性行为干预中的效果,为老年人艾滋病健康教育工作的开展提供科学依据。方法采用分层整群抽样的方法,随机抽取广西艾滋病高发地区农村老年人1200名,以村为单位随机分成同伴教育组和传统教育组,分别开展为期6个月的健康教育干预。基于IMB理论模型,设计调查问卷,干预前后,两组人群分别采用统一的问卷进行现场调查;通过倾向值评分匹配的方法消除混杂因素的影响,采用Epi Data 3.1、SPSS 26.0等软件对调查资料进行整理与统计分析。结果经倾向值评分匹配后,同伴教育组和传统教育组分别匹配成功532名老年人。干预前两组老年人的社会人口学特征、IMB模型各维度得分及高危性行为特征差异均无统计学意义(P>0.05);干预后两组老年人IMB模型各维度得分均较干预前有显著提高(P<0.01);且同伴教育组的得分均较传统教育组高(P<0.01)。与干预前相比,同伴教育组和传统教育组在干预后,多性伴行为的发生率分别从44.26%、51.60%下降到25.00%、23.66%(P<0.01);干预后,同伴教育组的婚外性行为发生率(63.16%)低于传统教育组(69.92%),且安全套使用率(45.83%)高于传统教育组(37.23%),差异均有统计学意义(P<0.01)。结论IMB模型在广西农村老年人艾滋病高危行为干预中具有良好的应用价值,但对不同高危行为的干预效果存在差异;同伴教育在老年人艾滋病高危行为中的干预效果优于传统的健康教育方式。在今后的老年人艾滋病健康教育中,应积极探索和推广同伴教育,特别是要倡导多种健康相关行为改变理论的联合应用,不断提升健康教育的干预效果。
