The evolution of development economics is closely related to the development of economic globalization , particularly at the third phase(in 1940's) of economic globalization , during which development economics in modern sense sprang up. Its main research is about how the poverty - stricken agricultural countries or developing countries achieve industrialization. From its appearance to before 1980's, development economics consists of two forming phases of structuralism and neo - classicism. Since 1980's , in the tide of new economic globalization ,development economics has new tendency and is faced with predicaments.

发展经济学的产生与发展和经济全球化的发展有密切的关系，特别是在经济全球化进入第三阶段，即20 世纪40 年代，现代意义上的发展经济学兴起，其主要是研究贫困落后的农业国家或发展中国家如何实现工业化的问题，发展经济学从兴起到80 年代以前，可分为结构主义和新古典主义两个发展阶段。80 年代以来，在新的经济全球化的浪潮中，发展经济学既出现了新的发展趋势，也面临着困境。

With Economic globalizing , which began in the late 1970's and developed in 1990's, economic factors become more and more important in international politics, and the trend of economic politicizing and political economizing appeared in international politics.

20世纪70年代中后期开始的经济全球化在90年代的迅速发展，使经济因素在国际政治中的地位和作用不断上升，国际关系出现经济政治化、政治经济化的趋势。这种新特征随着中国改革开放的进程，在20世纪80年代中后期中美关系中日益显现，并于90年代发展成为中美关系的主要特征。

In a record driven by elongated performances and an unending interstate (and recorded in various locales along the journey), this Sennett-fronted foursome mirrors its highly commended debut Me First with another mix of razor-sharp and patently droll songs－this round with more of an emphasis on beach-blanket pop than bell-bottomed country.

而到了怀旧之风弥漫主流音乐的年代，媒体也挖掘出更多乐风融合多元不拘一格但整体感觉却又独具一格的Indie艺人，他们玩漂亮旋律玩清新做派早已玩的炉火纯青却又不甘心一成不变，於是你发现他们的作品中蹦出了九十年代的流行朋克，八十年代的新浪漫，六七十年代的摇滚乐甚至沙滩冲浪乐，更早的乡村和老爵士也不在话下。

In the 1960s potential output accelerated to around 4% a year, largely because more women got jobs. In the early 1970s, for reasons that are still ill-understood, productivity growth slowed sharply, pulling down the trend rate of growth. Between the mid-1970s and mid-1990s America's economic speed limit was about 3%. Around half that growth came from an expanding workforce; the other half from productivity growth.

上世纪60年代，由于更多的妇女参加工作，潜在产出增长率加快到年均4%左右。70年代初，生产率增长急剧下降，因而压低了潜在经济增长率，其原因现在还不清楚。70年代中期到90年代中期之间，潜在经济增速保持在在3%左右，其中劳动力增长和生产率增长的贡献各占一半左右。

20世纪西方悖论研究是继古希腊和中世纪之后出现的第三次悖论研究的高潮时期，可划分为三个阶段：1 90 1年罗素悖论发现至 30年代末为第一阶段，主要以集合论悖论研究为重点；4 0年代初至 70年代中叶为第二阶段，逐渐转移到以语义悖论研究为重点；70年代中叶至 2 0世纪末为第三阶段，回归到自然语言，在语形、语义、语用的统一中研究悖论问题。
