“两个结合”是当下实现中华优秀传统文化“创造性转化”与“创新性发展”的根本途径,同时也是建构中华文化主体性的必由之路。中华文化的主体性是在长期发展过程中建立起来的,其中包含着历史选择的必然性。公元前2世纪中叶以降,中华文化实际上是向世界开放的,同时也在与不同文明的交往中不断实现其自身。因此,中华文化在历史展开过程中有着丰富的主体性建构的历史经验。如宋代理学本质上即是一场关于中华文化主体性建构的思想文化运动,阳明心学则是通过人的主体性重建来挽救朱熹理学作为“圣学”在实践上的弊病。

12世纪下半叶以朱熹、陆九渊、吕祖谦为代表的“宋学”诸形态是导源于唐代韩愈的“道学”运动所达成的终极思想成果。“道学”运动的目的在化解特定时代背景与思想语境之下被领悟到的某种文化危机,回归以儒学为典范的中国文化主体性,重建以道一性之本原性同一为基础的关于人的存在的价值根性,体现为一个具有历史连续性的根本主题。“道学”运动以儒学经典文本体系的重构为显著特征,以儒释语际困境的突破以及话语体系的转换为基本方式,以体用一源的思想一实践体系建构为终结形态,终于展开为“理学”“心学”“历史哲学”,是为“宋学”。

技术物是西蒙东开创的关于物的概念,它不同于古希腊和古罗马时期的自然物和物(拉丁语:res),也不同于笛卡尔时期的对象物。技术物本身就意味着人与技术物的关系,即人类通过技术物与周围世界的生态圈发生关联。在人类历史的过程中,技术物分别经历了手工业时代、工业化时代、信息化时代和数字化时代。观察技术物的历史嬗变,我们可以看到技术物将人类和世界综合在一起的能力越来越强大,越来越广泛,从单一个体和对象的关系,演化为工厂和城市化中生产关系和生活关系,延伸至信息时代的全球化的网络及自动化关系,最终在数字时代成为涵括整个地球有机物和无机物的一般机体学,这种一般机体学就成为拉图尔和当娜·哈拉维意义上的盖娅。盖娅代表着数字社会下的人与技术物的一般性关系,如广延性关系、操控性关系以及共生性关系等,这些一般性关系是数字时代的人们不得不面对的存在模式。

实证分析中期借贷便利利率对银行贷款利率影响的变化,检验LPR改革对提高我国货币政策利率传导效率的成效。结果显示,在LPR改革后,中期借贷便利利率能够显著影响银行贷款利率,其中中小银行贷款利率受到的影响更大,表明LPR改革能够降低企业特别是中小企业的融资成本,从而提高货币政策的利率传导效率。机制分析表明,LPR报价基准的替换、LPR被纳入银行内部资金转移定价(FTP)与宏观审慎评估考核(MPA)是LPR改革提高货币政策利率传导效率的主要机制。影响因素分析发现,存款利率市场化程度低是现阶段影响我国货币政策利率传导效率的重要因素。因此,为了进一步提升货币政策利率传导效率,存款利率市场化改革应该是下一阶段改革的重要内容。同时,货币当局与监管部门应该妥善处理好利率市场化改革与金融风险之间的关系。

由于负荷中心与可再生资源在地理位置上分布的不均匀,更大范围的资源合理配置需要跨区输电,而随着电力市场的深化发展,参与跨区电力市场出清的发电商将可能出现通过合作博弈策略行使市场力以争取自身利益最大的行为,此举可能导致跨区输电通道利用率降低,进而影响线路准许收入的稳定回收。为应对上述问题,提出了一种电力市场环境下考虑参与跨区出清的区外发电商合作博弈策略的跨区输电电价三层优化模型,上层为以准许收入稳定回收为目标的输电电价优化模型,中层为由区外发电商组成的跨区出清利益联盟的以联盟收益最大为目标的报量决策模型,下层为计及区外发电商参与的区内电力市场出清模型。为求解所提三层模型,采用了一种改进列和约束生成算法(C&CG)算法,将模型分解为主、子问题迭代求解,其中对于作为双层模型的主、子问题采用卡罗需-库恩-塔克条件(KKT)和大M法转化为等效单层模型后进行求解,而主、子问题模型中的双线性项则采用强对偶定理及变量离散参数化的方法进行线性转化以便于求解。最后通过PJM-5节点系统验证了所提三层优化模型能较好地体现区外发电商因合作博弈策略组成的跨区出清利益联盟的策略性决策和市场力行为,令输电电价的制定能在考虑区外发电商合作博弈策略影响下,实现线路准许收入的稳定回收。
