    Research on Controlled Economy Thought in the Republic of China

    上世纪三四十年代,统制经济思想渐成为国内的主流经济思想。统制经济思想是在世界经济大萧条、日本侵华和国内政治经济混乱的形势下的产生的,响应了当时时代的呼唤。因此一经产生便迅速被国内的学界政界所认可,国民政府也迅速践行,希冀在政府干预和市场调节之间求得平衡,运用调节经济的“两只手”来应对经济危机的冲击、日本战争的威胁和实现对发达国家的赶超。“两只手”的力量对比总是处在一个动态的平衡中,因社会环境的不同而不断变动。统制经济思想在兴起之初,常与计划经济的概念混淆,随着苏联渐成为“计划经济”的样板,而德国渐成为“统制经济”的样板,两者的界限开始明晰起来。国民政府最终采取了统制经济,赢得了抗日战争的胜利。...In the 1930s and 1940s, the thought of controlled economics has gradually become the main trend inland. This kind of thought, going along with the Great Depression, the invasion of Japan and the chaotic situation of native government and economic, responds to the calling of needs at that time. Therefore, once it emerged the educational and governmental circles reached consensus swiftly, and the na...学位:经济学硕士院系专业:经济学院_经济思想史学号:1532011115203

    Interpreter’s Initiatives from the Perspective of Relevance Theory

    本文是从关联理论角度对口译过程中译员能动性的一次理论探索。关联理论由Sperber和Wilson于1986年首次提出,后来进行了进一步修订。关联理论从语用学的角度将交际视为一种交际者利用自身能动性寻求最佳关联的过程。交际赖以产生的基础是交际双方共同拥有的认知环境,在认知环境中交际双方通过为彼此建立具有最佳关联性的语境使得对方能够使用最少的处理努力获得最多的语境效果,从而获得交际意图,顺利完成交际。 口译是一种特殊的交际过程,交际双方同样通过创建最佳关联传达交际意图,但是碍于语言不通,只有借助译员才能推动这一进程。然而与普通单语交际者相比,译员在交际过程中承担着更大的责任,并利用了更多的能动性...The thesis is an initial attempt to discuss interpreter’s initiatives from the perspective of Relevance Theory (RT). RT was first put forward by Sperber and Wilson in 1986. A few modifications have been made since then, making it more perfect and persuasive.
