青年是社会风尚的引领者和创造者,青年精神需求的变迁在一定程度上反映了一个民族文明形态的演进。新时代青年作为建设中华民族现代文明的先锋队和生力军,其精神面貌关涉以中国式现代化全面推进中华民族伟大复兴这一目标的实现。中华人民共和国成立以来,我国青年的崇拜对象经历了从实体到虚实并存的变迁,反映了青年精神需求质量、领域、功能的嬗变。虚拟偶像崇拜的风靡,映射出青年致力于追求创造力,但却迷失在娱乐化、商品化的虚拟偶像消费中,其实质为新时代青年精神需求与供给之间存在发展不平衡不充分的矛盾。正确认识虚拟偶像崇拜的精神实质,解析其中的矛盾与成因,探索多元合力培养新时代青年科学理性的价值观、消费观和创造观的路径,对于提升新时代青年的精神品质,激发其现实创造潜能,汇聚新时代青年力量推动中华民族现代文明建设具有重大意义。

当前国际形势复杂多变,我国正处于经济跃升的关键阶段,面临能源安全与“碳达峰、碳中和”(以下简称“双碳”)目标双重挑战。虽然能源安全是“双碳”目标的重要基石,但部分减排路径会对能源供应、电网负荷等与能源安全直接相关的要素产生约束,两者难以同时达到目标最优化。因此,如何理顺、优化能源安全与“双碳”目标的关系,协同推进两者发展,成为我国必须应对的挑战。电动汽车兼具节能、储能、减排等多方面效益,是保障能源安全与实现“双碳”目标协同发展的有力手段之一。文章以弱化政策间矛盾为出发点,提出建立以政策网络为保障、储能技术为立足点的双边整合协调系统,发挥电动汽车产业在构建兼容性政策网络中的保障作用,强化电动汽车在当前阶段的储能作用,联合政策—技术建立双边整合协调系统。

随着绿色可持续发展理念深入人心,ESG逐渐成为企业管理决策的核心要素,对供给侧结构性改革与劳动力市场健康有序发展产生了深远影响,其能否有效提升劳动投资效率值得深入研究。本文以2011—2021年A股上市公司为研究对象,实证考察了ESG表现对企业劳动投资效率的影响,究竟是“赋能”还是“负能”。研究发现,ESG表现有助于提升企业劳动投资效率,并主要通过缓解融资约束和增强员工创新两条机制予以实现。异质性分析显示,对于非国有企业、审计质量较低、非高新技术企业以及市场竞争地位较低的企业,ESG表现凸显出积极的治理效应,对劳动投资效率的提升效果更为明显。进一步分析发现,ESG表现能够显著抑制劳动投资过度及投资不足,且主要体现为缓解雇佣过度、雇佣不足与解雇过度。本文研究结论对深入推进企业ESG责任履行、优化劳动力资源配置和促进经济高质量发展具有重要意义与政策启示。

关键词： ESG表现劳动投资效率融资约束企业创新

加快建设生态友好的现代化新青海是青海省实现现代化的重点内容。文中综合运用土地利用转移矩阵、生态环境质量指数、重心迁移分析、标准差椭圆、地理探测器模型探讨了青海省1990-2020年生态友好等级区时空演变特征及影响因素。结果表明:1)青海省生产空间面积从1990年的8304.48km^(2)上升至2020年的9528.19km^(2);生态空间面积总量相对稳定,保持在71万km^(2)左右;生活空间面积增加迅速,至2020年增加到992.82km^(2)。2)青海省生态友好状况不断向好,全省生态环境质量指数从0.2731上升至0.2903,各市州生态环境质量呈波浪式上升趋势。3)各等级区呈由东南向西北迁移趋势,到2020年生态友好高质量区、较高质量区面积分别为95152.38km^(2)、133817.54km^(2),分别占比13.17%、18.53%。4)年均降水量是影响青海省生态友好等级区演化的核心因子,其次是户籍人口城镇化率和距市县政府驻地距离,年均降水量与距市县政府驻地距离交互对生态友好等级区空间分异的影响较强。
