21世纪以来,服务业务占制造业总收入的比例出现了一定程度的增长,制造业服务化的发展态势良好。从国际贸易视角出发研究进口竞争对制造企业服务化的影响,经验证据表明,服务化程度每提高10%,制造企业的收入平均增长2.25%。然而,随着进口竞争的加剧,服务化制造企业却难以在制造业务中维系自身稳定的销售收入。这表明,面对进口竞争,服务化并非制造企业维持或扩大市场规模的进取型策略,而更倾向于是一种规避进口竞争的消极策略。对此,中国需警惕由于贸易全球化所导致的产业空心化问题,制造企业应紧密围绕产品打造高度关联的服务业务,从而夯实实体产业发展的根基。

慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)是以气流受限为主要特征的一类疾病,与吸入香烟、烟雾等有害气体或有害颗粒引起的复杂病理改变有关,包括大、小气道的炎症和肺实质的破坏。COPD的发病机制尚未十分明确,目前认为与气道炎症、免疫因素、氧化应激、蛋白酶及抗蛋白酶失衡等机制有关。与COPD发病机制密切相关的分子生物学标志物在疾病发生发展过程中发挥着重要作用,文章对不同发病机制对应的分子生物学标志物进行综述。

为深入研究社会经济地位对青年社会参与的影响机制,剖析社会评价因素对其中作用机制的中介传导效应,文章采用2019年中国社会状况综合调查(CSS)数据,利用SPSS 26.0和MPLUS 7.4软件的中介效应统计分析工具解析社会评价在社会经济地位和青年社会参与之间的影响机制。研究发现:社会经济地位与青年的社会参与显著正相关,社会评价在社会经济地位和青年社会参与之间发生了部分中介效应。这些研究发现验证了基于马斯洛需求层次理论和角色理论提出的研究假设。研究结果为深入认识社会经济地位如何影响青年的社会参与提供了新的见解,有利于加深对青年经济地位和需求角色的理解。
