贸易开放与发展中国家收入差距扩大——基于中国的理论与实证分析

文章将人力资本结构因素纳入到贸易开放与发展中国家内部收入差距关系的分析框架之中,通过理论推理和实证检验考察了贸易开放、人力资本结构对发展中国家收入差距扩大的影响机制、条件与力度.研究表明,贸易开放对发展中国家收入差距扩大的影响不但与其所带来的技术进步类型有关,还与该国的产业发展战略和人力资本(人才供给)结构密切相关.就我国而言,人力资本结构升级速度慢于贸易产品结构升级速度,是贸易尤其是出口导致收入差距扩大的重要条件.     

Foreign Investment and the Mediation of Trade Flows

How does foreign direct investment affect the trade between nations? While many theories of the multinational firm are based on the premise that foreign production and trade are substitutes, most empirical studies of foreign investment and trade uncover a complementary relationship. This paper shows that the mismatch between theoretical work and empirical findings is a byproduct of data aggregation. When the unique country–industry patterns of mostly OECD country foreign investments in the US are analyzed, predicted substitution patterns are revealed at the data level that roughly corresponds to broad products. The complementary effects of foreign investment on trade emerge at higher levels of aggregation.     

Economic gains from technology-intensive trade: an empirical assessment

National investment in technological activity is commonly justifiedin terms of the positive impacts upon productivity, internationalcompetitiveness and related aspects of national economic performance.This premise has found a supportive theoretical framework inthe new technology and growth models. Based on extended technology-gapmodels, this study examines cross-country empirical evidenceon the relationship between technology-intensive trade performance(as a proxy for technological output) and per capita economicperformance, utilising 1978 to 1992 data for around 45 nations.The results provide some support for a positive relationshipbetween trade performance and economic returns. However, theweak and often inconsistent results suggest that the unconditionalpursuit of technology-intensive trade improvements may not necessarilyhave the expected net benefits.     

Political Economy of Trade Openness and Government Size

This paper proposes a theoretical model that may provide useful insights into the relationship between trade openness and the size of government, as well as a possible explanation for the results of empirical tests of such a relationship. We develop a Hecksher–Ohlin model with publicly provided goods, where the level of publicly provided goods is determined in a probabilistic voting framework. In this context, we show that the start of trade may increase or decrease government size depending on the capital‐labor ratio in each country.     

基于中国经验重构新新贸易理论的分析框架

异质性企业贸易模型是新新贸易理论的基本分析框架,该模型从企业生产率异质性角度分析企业出口的决定因素,得到企业拥有高生产率是保证其出口的重要条件,从而出口企业的生产率要高于内销企业的结论。不过,对中国企业的经验研究却发现,出口企业的生产率未必高于内销企业,甚至低于内销企业,即中国出口企业存在"生产率悖论"。目前,对于"生产率悖论"的研究主要集中于经验分析,并没有提出一个合理解释该现象的理论模型。文章从扩展异质性企业贸易模型的角度,建立了一个旨在解释"生产率悖论"的数理模型。尽管该模型对"生产率悖论"具有解释作用,但是并没有否定生产率对企业出口的作用。文章进一步使用较新的LP方法计算了中国制造业企业的生产率并运用统计法检验了出口企业"生产率悖论"的存在性,检验结果表明中国制造业大部分行业不存在"生产率悖论"。总之,文章研究认为生产率只是企业出口的一个必要条件而不是充分条件,这也重新构建了新新贸易理论的分析框架。     

双边自由贸易协定深度异质性及区内全球价值链效应*——基于GVC修正引力模型实证研究

双边自由贸易协定深度嬗变,全球价值链引致贸易形成机制和形式变化,使得自由贸易区理论基础、影响机制和功能效应更替。本文基于对双边自由贸易协定深度演化以及相较于其他区域贸易协定的深度异质性研究,将公司产权理论纳入自由贸易区理论框架,形成双边自由贸易区内全球价值链效应的多维理论机制,并且运用适应全球价值链发展的修正引力模型和世界银行的贸易协定内容数据库对理论机制假设结论进行实证检验。研究发现：双边自由贸易协定总深度对区内成员国之间的全球价值链关联产生正向影响,相较于贸易相关条款深度而言,投资相关条款深度影响更大。此外,自由贸易区对象国差异性也会影响双边自由贸易区全球价值链效应的发挥。根据对象国不同选择差异化的自由贸易区深度在双边自由贸易区构建中重要性凸显。本文将为全球价值链背景下中国构建高标准自由贸易区网络的对象国选择、自由贸易区模式选择等提供政策参考。     

Exports versus FDI in German Manufacturing: Firm Performance and Participation in International Markets

Recent theoretical work has been able to explain how even within narrowly defined industries, firms can exhibit heterogeneous degrees of participation in international commerce. Differences in productivity between firms are the principal explanation offered by theory to explain heterogeneity with respect to international commerce. In particular, theory predicts that the least productive firms will produce for the domestic market only, while better performers engage in export activities, and the top firms establish foreign subsidiaries. This paper presents an empirical test of the relationship between productivity and patterns of international trade and production. Using German firm‐level data from 1996 to 2002, we test the predicted rank ordering of productivity according to firms’ trade pattern by examining the distribution functions of the three subsets of firms for stochastic dominance. Our results are generally consistent with the predictions from theory, and document significant productivity differences according to trade patterns.     

(Asymmetric) trade costs,real exchange rate hedging,and equity home bias in a multicountry model

There has been controversy between (two‐country) theory and the empirics about whether hedging against real exchange rate fluctuations in the goods market influences foreign equity holdings. This study reconciles the theory with the empirics by introducing a multicountry framework with asymmetric trade costs. We find that the incentive to hold foreign equities to hedge real exchange rate risk is negligible because multiple trade partners act as a hedging channel for real exchange rate fluctuations. Further, our theory calls for a country's covariance–variance ratio to be constructed as the sum of the bilateral covariance–variance ratios of the multiple partners. The empirical analysis of 24 advanced countries confirms the theoretical prediction.

An alternative consideration for the testing procedure of the S-curve hypothesis

Backus et al. (Am Econ Rev 84:84–103, 1994) introduced a new theoretical interpretation of the short-run relationship between the terms of trade and the trade balance: movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in the terms of trade, but positively correlated with past movements. There have been several papers aimed at testing the S-curve hypothesis in the related literature. The most common empirical approach used in those papers is the cross-correlation analysis. This paper highlights several deficiencies of the cross-correlation analysis when being used directly to test for the validity of the mentioned hypothesis. The purpose of this paper is to offer an alternative approach so as to combine the causality theory in econometrics with the testing procedure of the S-curve hypothesis via the cross-correlations. The paper’s empirical results reveal that disaggregated bilateral trade data between the United States and China almost never support the S-curve hypothesis, contrarily to a previous paper employing the same data, but utilizing the conventional cross-correlation analysis. Why this difference may have appeared is also discussed.     

贸易开放和人力资本形成的非线性关系——理论和基于我国省际动态面板数据的实证研究

本文通过理论模型分析了贸易开放影响人力资本积累的两种途径:改变人力资本相对报酬和国外知识溢出,贸易开放能否促进人力资本形成取决于两种途径的相对大小。同时本文使用中国省际动态面板数据对贸易开放如何影响人力资本形成进行了实证研究,发现贸易开放和人力资本之间存在U型非线性关系,即当贸易开放度比较低时,贸易开放度的提高不利于人力资本形成;而当贸易开放度达到一定程度后,贸易开放度的提高则有利于人力资本形成。     

外贸对经济增长的影响分析:理论与经验模型验证

国际贸易理论的核心问题是探究贸易利益的产生及其分配,国际贸易与经济增长具有密切联系。理论分析和经验证据均表明,一国外贸规模对经济增长有着重要作用,对外贸易的变动往往成为决定一国经济增长趋势的关键因素。文章从理论和经验模型上对我国近10多年来外贸和经济增长的关系给出了相关的实证检验,旨在探讨并揭示国际贸易促进经济增长的内在机制。     

中国工业贸易保护结构政治经济学的实证分析

贸易的政治经济学将公共选择的分析范式引入传统贸易理论,从收入分配而非经济效率的角度出发,从政策决策过程的视角来探究贸易干预的水平和结构。本文将这一贸易保护的"内生化"理论应用于中国的实证分析,在文献研究的基础上发展了一种适用于中国"国家战略主义"体制下的贸易保护的政治经济模型,并通过计量回归的实证研究来验证若干理论假说的真实性和显著性,从而说明中国工业不同时期跨部门的贸易保护结构的政治经济决定因素。     

全要素生产率、人民币汇率与中国贸易收支——基于跨期最优选择理论的实证研究

文章首先以跨期最优分析框架为基础建立以中国贸易收支为研究对象的理论模型,然后基于中国1999-2009年省际面板数据,运用面板FMOLS估计方法,从全国和地区两个层面对中国全要素生产率、人民币实际汇率与中国贸易收支的关系展开实证分析。研究表明,中国贸易部门内资企业和外资企业的全要素生产率提升均对中国实际贸易余额增长产生了正面影响,其中东部地区的促进作用最为强劲;中国非贸易部门全要素生产率与其实际贸易余额负相关,其中东部和中部地区非贸易部门全要素生产率提升会显著减少该地区的实际贸易差额;人民币实际有效汇率提升对中国实际贸易收支具有显著的负面影响,并按照东部、中部和西部地区依次加重。根据上述分析结果,文章提出了调节中国贸易收支的相关政策建议。     

异质性企业贸易理论的起源与发展

本文旨在系统性地探究异质性企业贸易理论的起源与发展过程。首先对促使该理论诞生的实证挑战从企业的选择性出口、市场进入成本、资源再分配三个方面进行了综述;然后指出该理论发展的两条脉络和各自的理论基础,并在此基础上从平均生产率和贸易利得两个角度阐述了异质性企业贸易理论和新贸易理论之间的紧密联系,二者最大的差别便在于对边际生产成本的处理上,前者以边际成本的异质性替代企业的异质性,后者则忽略了企业之间的异质性。同时,针对国内学者的一些认识,本文也提出了自己的看法。     

Migrant Networks: Empirical Implications for the Italian Bilateral Trade

A significant number of empirical studies, focusing on different countries, have found a positive link between migration and trade. This paper studies the relationship between emigration, immigration and trade using Italian data. The sample regards 51 foreign trading partners and spans from 1990 to 2005. The results suggest that networks of Italian emigrants in foreign countries boost bilateral trade. The effects of immigrants are weak on exports and negative on imports. Results do not change when cultural and institutional dissimilarities between countries are considered.     

贸易开放与性别工资差距

本文在不完全竞争市场环境下,建立贸易开放和性别工资差距的数理模型。在理论分析的基础之上,本文运用2002年中国家庭住户收入项目调查数据(CHIP)进行实证分析。在控制了年龄、婚姻状况和受教育年限等个体层面和人均GDP等城市层面的工资影响因素情形下,得出结论:贸易开放在总体上拉大了性别工资差距;贸易开放缩小了高技能劳动力的性别工资差距,拉大了低技能劳动力的性别工资差距。从某种意义上说,女性弱势群体更容易被排除在贸易开放的利益之外。因此,提高女性的受教育程度,并为之提供相应的制度保障具有尤为重要的政策含义。     

Tourism and trade in OECD countries. A dynamic heterogeneous panel data analysis

This article studies the empirical link between international tourism and trade. We apply dynamic heterogeneous panel data techniques to analyse both long and short-run relationship for the case study of OECD countries. This link is studied by estimating the cointegration vector and analysing the short causality between variables. The analysis recognises that inbound tourism can promote international trade and also that international flow of goods requires and may encourage tourist arrivals and departures. The statistical significance of this link supports the presence of business opportunities due to the potential complementary relationship between tourism and trade. The results suggest a short-run nexus between tourism and trade, and that these variables are cointegrated.     

Taxes,Risk Aversion,and the Size of the Underground Economy

Non‐parametric regression analysis was used to investigate the relationship between the effective tax rate and the relative size of the underground economy, using New Zealand data. The underlying theoretical framework is established, and it suggests an ambiguous prediction regarding the sign of the relationship we are studying. However, our non‐parametric empirical analysis, which also allows for the non‐stationarity of the time‐series data, produces a positive and ‘S‐shaped’ relationship, and this supports earlier empirical studies that imposed such functional forms. The estimated model is used to simulate the effects of hypothetical tax changes on the size of the New Zealand underground economy, and to draw policy conclusions.     

Political economy of China’s trade policy: the evidence from industrial protection in 1990s

The theory of the political economy of trade policy, combining public choice and neoclassical trade theories, studies the level and pattern of trade intervention from the perspective of policy decision-making process, by stressing on income distribution instead of economic efficiency. The paper attempts to apply such an endogenous trade theory to an empirical study of China. On the basis of a formal revised model of political economy of trade protection, it tests theoretical hypotheses concerning the political and economic determinants of cross-sector trade protection in the Chinese industry at various periods. The results show that trade protection in China fits into China’s national development strategy of fast catching-up with the developed world.
