我国英语有效教学研究的回顾与展望

英语有效教学是国内外长期关注、研究的课题。文章从历时视角,重点梳理了国内有效教学以及英语有效教学三个研究阶段的主要特征及相关问题。同时,对在信息化、智能化高度发达的时代如何开展英语有效教学做了思考和展望。     

区域二重开放下的产业空间演进研究

产业的空间演进是产业为了实现利润最大化而对其空间区位进行选择及变换的过程。基于区域二重开放的经济现实,在新经济地理学分析框架之下构建两国三区域模型,比较垄断竞争条件下企业在各个区位的收益,推导出企业空间区位演变的判决条件,进而构建产业空间区位演进系统。分析表明:企业是否进行空间区位变换取决于其区位变换带来的收益与成本能否使企业实现利润最大化,而影响该收益与成本的关键因素则是贸易自由度、区域内的要素成本等区位因素。因此,一国政府可以通过调整和控制国家间以及区域间的贸易自由度来引导外商以及国内企业的区位演变,尤其是对于具有低工资优势的地区而言,加大该地区与国内其他具有高开放度地区之间的区际开放度,或者提升其直接对外贸易的开放度,都有利于吸引区外产业进驻该地区。     

中韩服务业产业内贸易实证研究

分析2000-2010年中国与韩国双边服务贸易G-L指数和MIIT指数,结果表明:中韩两国在运输服务、旅游服务和通讯服务等部门呈现出较高的产业内贸易水平,但在其他商业服务和政府服务等部门则以产业间贸易为主要;从动态变化的角度来看,两国服务业的边际贸易有明显趋向于产业间贸易的变化趋势,说明中韩服务业存在较强的互补性.劳动和资本要素对服务业比较优势和贸易格局的影响在逐渐减弱,而政府的产业政策逐渐成为决定服务贸易竞争力和贸易格局的重要原因之一.因此,应采取积极的产业政策,提升我国服务贸易竞争力,改善贸易结构.     

外部融资依赖、金融发展与出口贸易增长

基于2001—2012年中国29个省区的面板数据,分析在不同的外部融资依赖度条件下两种主要的外源性资金（银行信贷和外商直接投资）对地区出口贸易产生的影响,研究结果显示：银行信贷和外商直接投资是影响地区出口贸易的显著因素,且外商直接投资对出口贸易的作用效果更强;外部融资依赖特征不同的地区,不同融资渠道对出口贸易产生的影响也不一样;在外资依赖度较高（大于0．07％）的地区较高的信贷密度（大于0．35％）更有利于出口增长,而在外资依赖度较低的地区需要寻找适宜的信贷密度与之相匹配;在外资密度较高（大于1．64％）的地区信贷依赖有利于出口增长,而在外资密度较低的地区信贷依赖会给出口带来不利影响。     

Genoa,Genoese Merchants and the Ottoman Empire in the First Half of the Fifteenth Century: Rumours and Reality

Among the Latin states, it was the maritime republic of Genoa that established the earliest official contacts with the Ottomans by concluding a treaty with them in 1352. This was the first step in the development of relatively smooth relations between the Genoese and the Ottoman Empire, which lasted from the mid-fourteenth until the mid-fifteenth century. Within Christendom, such familiarity earned the republic a negative reputation, which the adversaries of Genoa – Venice among others – tried to exploit for their own purposes. An element that contributed to the idea of a close connection between the Genoese and Ottomans was the outstanding position gained by some citizens of Genoa at the Ottoman court. They were influential men of affairs who owed their acquaintance with the sultans to their specific commercial activity. However, despite the fact that in some cases they held offices in the Genoese colonial administration, these merchants acted quite independently of Genoa itself and sometimes contrary to its directives.     

Markets in Tenth-Century al-Andalus and Volga Bulghāria: Contrasting Views of Trade in Muslim Europe

There is a conspicuous absence of interest in markets and commercial activities in recent studies of al-Andalus. A similar problem existed in the Marxist historiography of commercial relations in Eastern Europe during the early Middle Ages. Although Soviet scholars initially downplayed trade in favour of agriculture and crafts, the explosion of archaeological research in key Bulghar centres, as well as the discovery of a number of sites that may be defined as emporia have dramatically changed both the terms of the discussion and the role of trade in studies of urbanisation and state formation. This may in turn provide inspiration for the study of trade in contemporary al-Andalus. Moreover, the recent emphasis on hydraulic archaeology and its role in explaining the extraordinary wealth of al-Andalus in the tenth and early eleventh centuries provides a useful background for a re-assessment of the question of trade in the westernmost region of medieval Islam.     

Amalfitans in the Caliphate of Cordoba – Or Not?

This article concerns itself with the references in Ibn ?ayyān's Muqtabis, Book V, to an Amalfitan presence at the court of Cordoba in the middle of the fourth/tenth century. It will be argued that these isolated references to a precociously early, Italian, mercantile presence in Spain, taken largely at face value by the text's editor and all but neglected in Amalfitan historiography, need to be interrogated to determine whether they fit the fourth/tenth-century context of Amalfitan–Muslim relations, or should be read against their fifth/eleventh-century context as evidence for a golden age of the Caliphate which, by Ibn ?ayyān's day, was already passing into memory and myth. Using contemporary, comparative evidence from Barcelona, the article examines the possibility of communications between Italy and Spain in the earlier period, and concludes that the conditions were probably right for an Amalfitan arrival, but rapidly changed by Ibn ?ayyān's day to exclude them from further contacts.     

国内高校学生心理健康研究综述

高校学生心理健康一直都受广大学者的关注,纵观近年来国内学者对高校学生心理健康研究,对普通高校学生的心理健康的研究很多,研究的方面也比较得全面,很丰富,但是对独立学院的学生的研究十分少。对独立学院学生的研究无论是理论上还是实证调查的研究还十分的薄弱,从广度和深度上还没有很全面的研究。尤其是对当前独立学院学生心理状况以及存在的问题还没有提出有针对性解决办法。与普通的高等院校一样,独立学院院校学生心理健康不该只是一时关注,更需要的是长期的重视和引导,要形成一整套的机制。     

国际金融危机视角下中国内需与外需的关系研究

在国际金融危机冲击下,中国出口大幅度下降,依赖外需带动的经济增长方式难以为继。国家遂将经济增长的重任委以内需,然而内需和外需作为中国经济两大主要成分．二者之间存在复杂而微妙的关系。文章重点对中国内需与外需的关系进行了分析。认为近年来中国内需与外需之间存在相互抑制和替代的关系,尤其是外需对内需的抑制和替代。这给中国经济造成了诸多的负面影响。文章最后提出了改善中国内需与外需关系的对策建议。     

国内需求、贸易与就业——基于国民经济核算角度的分析

本文利用1997--2006年中国工业部门面板数据,从国际收支角度出发,研究了国内就业与贸易及国内需求的关系,结果表明贸易对劳动力就业具有非常显著的影响,同时国内需求的扩张也会促进就业增加。研究支持了相关文献中出口会提高就业的假说。当加入考虑工业行业工资变动、技术进步资本积累等因素时,贸易和国内需求对就业的影响更为多元化和复杂化,最终就业不仅依赖于出口扩展,同时也依赖于国内对非贸易品需求的扩大,如国内投资、教育投入等。
