基于世界投入产出(WIOD)数据库与世界银行(WB)数据库,考虑人口老龄化背景下产业智能化如何影响益贫式增长。研究结果表明:人口老龄化对益贫式增长产生显著的抑制作用,而产业智能化对益贫式增长具有显著提升效应。在考虑不同估计方法和指标测算方法后,这一结论依然稳健。其次,异质性分析显示人口老龄化背景下产业智能化对于发达国家、后人口红利时期以及劳动密集型行业的益贫式增长的促进作用更为显著。最后,进一步分析发现老龄化背景下产业智能化主要通过岗位迭代效应与生产率效应机制影响益贫式增长,并通过gAM拟合图分析演变路径。研究结论对于人口老龄化背景下产业智能化转型升级以及促进益贫式增长、实现共同富裕具有重要启示。

基于黏性末端链置换（TMSD）非酶扩增技术构建了一种简单、高灵敏的电化学发光/电化学比率传感方法用于miRNA的检测。本方法以修饰在电极上的亚甲基蓝（MB）产生的EC信号作为内参比信号，并将Ru（phen）32+嵌入到通过分支杂交链式反应（bHCR）产生的DNA纳米微粒中作为ECL探针。目标物存在时，MB脱离电极表面并使ECL信标修饰在电极上，从而使EC信号减弱，ECL信号增强，采用ECL和EC信号比值（ECL/EC）作为输出信号，降低了潜在干扰，提高了传感器的重现性和灵敏度。体系的ECL/EC比值与miRNA-21的浓度在10 fmol/L～500 pmol/L范围内具有良好的响应，检出限为6.5 fmol/L。与单一使用ECL信号的方法相比，在测定1 pmol/L的miRNA目标物时，响应信号的相对标准偏差从8.2%下降到4.1%。本方法成功应用于复杂细胞样品中miRNA-21的检测。

共同机构投资者同时关联行业内多家上市公司,集成强大的信息资源网络,影响企业投融资结构安排。文章以2007—2022年A股上市公司为研究样本,探讨共同机构投资者与投融资期限错配之间的作用关系。研究发现,共同机构投资者的存在、持股比例、横向联结均有助于改善投融资期限错配。机制检验发现,共同机构投资者能够通过增强供应链上话语权、提高商业信用水平以及降低交易成本等,在公司生产经营过程中产生“开源节流”效应,进而减少投融资期限错配。拓展分析表明,共同机构投资者能够与内外部公司治理机制协同作用,对内部控制有效和媒体关注较高的企业作用更为明显;共同机构投资者还能弥补不完全契约和正式制度的缺陷,尤其是对契约环境较差、行业竞争度较低的弱势群体起到了替代性治理作用。经济后果检验发现,共同机构投资者还能进一步强化供应链系统稳定和推动可持续发展,这对助力我国实体经济高质量发展和畅通国内经济循环具有一定的启示作用。
