关于近代中国“半封建”问题的辨析

河北学刊 2009年第4期29卷 81-88页

作者：王先明南开大学历史学院天津300071

关于中国近代社会特性问题,近来的焦点主要集中在"半封建"之释义上。20世纪的"封建"尤其是"半封建"概念的凝练及其时代特征,都不是仅仅以西欧或西周之"封建"制度的比对所能诠释或所能否定的。"半封建"特性在20世纪二三十年代获得了学术... 详细信息

关于中国近代社会特性问题,近来的焦点主要集中在"半封建"之释义上。20世纪的"封建"尤其是"半封建"概念的凝练及其时代特征,都不是仅仅以西欧或西周之"封建"制度的比对所能诠释或所能否定的。"半封建"特性在20世纪二三十年代获得了学术界相对一致的认同,不能简单评判为共产党或列宁主义唯一理论的一种认识。根据中国近代社会的现实状况,"封建残余"或"半封建"的存在并非不可理解,也并非违反了"知识"和学理"逻辑"。对于中国近代社会"半封建"的认识,与马克思多层次的"封建"概念并无抵牾。"半封建"理论的出现不仅仅是一个概念流变问题,而且形成了一个特定的历史时代。

In this paper the electronic structure of A1B2-type USi2 has been explored using DFT, DFT＋U and hybrid functional （HSE） methods. It reveals that c/a has great effect on the electronic structure, particularly theforbitals, and there exists strong hybridization between the Si-p and U-d orbitals in A1B2-type USi2. These calculations uncover that there exists similarities on the crystal structure and the electronic structure between AIB2-type USi2 and UaSis. Present calculations provide a further insight on the U3Si5, a heavy-fermion system.

人民币国际化问题已成为各国学者研究的热点。本文依据弗里德曼货币需求函数设立国内货币需求模型,并基于间接测算法和模型稳定性检验结果,选取1992—2003年的季度数据估测2004—2014年季度人民币境外存量,以此作为人民币国际化的衡量标准。在此基础上运用协整理论、格兰杰(Granger)因果检验、脉冲分析法等时间序列处理方法对我国现有的国际收支结构、经济规模、实际汇率及人民币国际化之间的动态关系进行实证分析。本文研究发现,上述变量之间存在长期稳定的均衡关系,我国经济规模扩大、经常项目顺差和人民币稳步升值有利于推动人民币国际化进程,而资本和金融项目顺差会对人民币国际化产生阻碍作用。因此,在发展国民经济及维持人民币币值坚挺的同时,合理调整我国国际收支双顺差结构也是人民币国际化进程的客观要求。
