在历史及文化传统中探索经济增长决定因素的内生化过程不光是经济史学者长期关注的议题之一,对理解改革开放以来我国经济高速发展也具有现实意义。但是,目前相关文献依然数量有限且结论不一致,大都以描述和思辨为主,缺乏基于系统数据的因果证据。本文结合明代设立军屯这一政策背景,发现家族在内部选定戍边军户过程中所界定出的成员间权利义务关系可以体现出一定的契约精神。我们基于系统历史数据,来探索这种“合同型”家族分布对现代语境中契约精神的影响。基础回归结果发现,历史上军户人口比重的确显著影响了当代契约精神,该结果在用明初战争频度作为工具变量后依然稳健。

中央金融工作会议提出了“把马克思主义金融理论同当代中国具体实际相结合、同中华优秀传统文化相结合”的重要思想。“两个结合”作为未来金融工作的战略性指导原则,值得在思想层面、理论层面、实践层面进行深入解读与落实。中国在悠久的发展过程中,积淀了丰富而灿烂的经济伦理与金融文化。“见利思义”“义以生利”的儒家传统义利观,以及千百年来逐步演化出来的强调诚信、道义的经济伦理与金融哲学,至今仍具有重要而特殊的现实意义。文章尝试系统梳理中国优秀传统商业伦理与金融文化,并为当下中国金融发展和改革提供借鉴。

本文研究历史上村民自发组织修筑水利设施的行为是否能够对其后的村民公共事务参与产生长期持续影响。基础回归发现历史上民间修筑水利设施显著提高当前农村人群参与本村公共事务的积极性。文章利用集体化时期国家统一管理水利的政策冲击和样本出生队列信息构造双重差分,同时也使用历史上的年降水量及其二次项作为工具变量进行策略识别,结果依然稳健。进一步地,本文还发现民间修筑水利设施带来的乡规民约及村民之间信任程度提升是历史上民间水利促进当前村民参与公共事务的机制。本文的发现有利于理解中国当前乡村治理过程中村民参与发育程度的历史起源,以从历史传统中寻找促进乡村治理现代化的线索。

从中共一大提出生产资料“归社会公有”的纲领,到20世纪30年代初期以“国家完全独立”为前提竭力促进工业发展、重要经济命脉实行国有的主张,再到抗日战争时期“要努力于中国的工业化”的思想,1949年以前中国共产党逐步形成了未来工业发展和工业化的目标。同时,中国共产党在早期领导工业生产实践中重视工业自给、统一计划、全民动员、发展公营工业等要素,而这些要素恰恰是后来新中国工业化建设中的鲜明特征。这些早期探索与实践为中国式现代化道路奠定了最初的基础,亦是中国式现代化道路的重要探索。

Vitellogenesis is the main event of oocyte growth in oviparous animals,which is mainly manifested by the accumulation of vitellogenin(VTG).The accumulation of vitellogenin depends mainly on the absorption of exogenous vitellogenin,which enters oocyte through endocytosis mediated by its receptor(VGR).We investigated the expression and localization of VTG and VGR during gonad development of Pampus *** qPCR results show that vtgs were not expressed in male fish,but in the ovary and liver of female fish;the expression levels went up at first and then *** expression levels of vgr in the testis were low and only 1%-3%of that in *** results show that during the ovarian development of ***,VTG in liver,serum,and ovary all showed a trend from increasing to ***,VTG in liver peaked in StageⅣ,and in serum and ovary peaked in Stage V,reflecting changes in the characteristics of VTG in the liver(synthesis),blood(transport),and ovaries(accumulation).During gonad development,VGR in the ovaries first increased and then decreased,reaching a peak in Stage V,in contrast to vgr mRNA *** VGR content in the testis was extremely low and stable,consistent with vgr *** results show that the location and intensity of VTG and VGR positive signals were synchronized with the changes of their protein content,which revealed that VTG was mainly synthesized in the liver cytoplasm,secreted into the blood,and transported to ovary in StageⅢ.VGR is highly expressed in oocytes in StageⅡ.In StageⅢ,a large amount of VTG reaches the ovary,when VGR begins to translate and is subsequently transported to the plasma membrane of the ***,the positive signal of VGR was stronger near the plasma membrane of oocytes in StagesⅠandⅡ.By using qPCR,ELISA,and immunohistochemistry,the synthesis,transport,and accumulation of vitellogenin were elucidated and the mechanism of its endocytosis on egg membrane mediated by VTG during the de
