外商直接投资与服务贸易国际竞争力——来自77个国家的经验证据

近年来,部分学者在FDI对服务贸易国际竞争力的影响效应方面进行了研究,结论却截然不同。为从一般意义上揭示两者间的关系,文章选取77个国家1980-2008年相关数据,并采取只考虑出口因素的lnRXA指数及同时考虑进出口因素的RC指数来衡量服务贸易国际竞争力,分别从总体、经济发展水平及服务业FDI限入水平三个层面进行了实证检验,结果表明:总体来看,FDI流入不会提高一国服务贸易国际竞争力,而不同经济发展水平及服务业FDI限入水平国家的FDI流入会产生不同的影响效应;除高限入水平国家外,服务业GDP不会提升服务贸易国际竞争力;服务出口及货物出口分别会对服务贸易国际竞争力产生显著的正向及负向影响效应。此外,服务贸易国际竞争力衡量指数选取的不同会造成FDI流入的影响效应产生较大差异。     

Development of intellectual property laws for the Russian Federation

In most industrialized nations, the concept and body of intellectual property laws is well into its third century of development and testing. The Russian Federation, however, has created and implemented an entirely new body of intellectual property law since the collapse of the Soviet Union in 1992. As American and other western firms work with the Russian Federation as a supplier and customer, they must recognize that the new nation has abandoned a legal philosophy denying the existence of intellectual property in favor of intellectual property laws recognizing and favoring private development and ownership of such property. This paper examines the Russian intellectual property laws and points out adaptations that western nations should make when dealing with similar entities in the Russian Federation. The study assumes familiarity with Russian history, language, and geography. A caution to domestic firms is that they should retain experienced legal counsel to deal with negotiations and contracts with Russian business interests.     

国贸专业统计学课程教学内容的改革与设想

统计学是国贸专业必修的基础课程之一。当前,在国贸专业统计学教学中存在的突出问题是统计学与国贸专业的其他相关课程在教学内容上严重重复;所列实例针对性不强,缺乏与国贸专业相关的实践教学内容。为了有效地将统计学的基本方法和原理应用于国贸专业的实际工作中,必须改革国贸专业统计学课程的教学内容,对统计学课程教学内容进行系统的模块设计和分块教学,使之更加合理化,做到学用紧密结合。     

我国进口贸易技术结构的变迁分析与国际比较：1985—2008

本文采用进口技术复杂度指数和按技术水平分类方法,基于细分的进出口产品数据,考察了我国1985—2008年的进口技术结构的变迁。研究表明,1985—2008年间,我国进口技术复杂度不断上升,明显高于日本、印度、东盟等国家;进口结构已由进口中、低技术制成品为主转移到进口高、中技术制成品为主;相对而言,我国高技术产品进口份额远远高于同类型的其他国家,而资源性产品和初级产品进口份额则显著低于样本中的其他国家。我国应扩大先进技术设备、能源原材料以及资源性产品的进口,进一步优化我国进口贸易结构。

The impact of agricultural policy distortions on the productivity gap: Evidence from rice production

This article explores how production and trade policy distortions affected rice productivity in 33 rice-producing countries. A rice-productivity index is constructed, and a model linking the productivity gap with policy distortions is presented. After controlling for the differences in infrastructure, access to inputs and equipment, openness, and human capital, this article shows that high levels of rice subsidies and protection in rich countries combined with taxation of rice farming in poor countries widened the gap in rice productivity between rich and poor rice countries.

Follow the leader: fund managers trading in signal‐strength sequence*

When fund managers trade sequentially in the same direction, the information confirmation hypothesis predicts the long‐term profitability of the leader trade to be increasing in the number of subsequent trades. The information cascade hypothesis predicts a non‐positive relationship. Using active equity funds’ daily trading data, we document a transition from information confirmation to information cascades as the number of followers increase. We find that highly disguised multiple‐broker packages exhibit higher market impact, higher long‐term returns and are associated with fewer followers. Our study also documents that lead fund managers face portfolio risk constraints in trading on private information.     

比较优势与国际区域贸易——基于上海对外贸易地理方向分析

比较优势理论是国际贸易中的一个重要理论,通过从大洲级别和国家（地区）级别这两个角度研究分析2001年至2008年间上海市对外贸易地理方向现状与变化趋势,发现上海市对外贸易地理方向主要集中于亚洲、欧洲、美洲等区域的发达国家或地区。这一实际符合比较优势理论的应用结果。
