近年来,区域经济一体化的进程不断加快,这是世界经济发展的必然结果。随着中国与拉丁美洲经贸关系的不断发展,中国已和智利、秘鲁和哥斯达黎加三个拉美国家签订了自由贸易协定,为双方的贸易带来了可观的收益,极大地推动了中国参与区域经济一体化的进程。本文在综述国内外相关文献的基础上,以中国与智利的自由贸易协定为例,采用引力模型,定量研究两国的经济一体化程度以及区域经济一体化所创造的贸易效应。     

The effects of integration agreements in Western Hemisphere trade, 1970–2014

The paper analyzes the effects of four regional integration agreements (Common Market of the South [MERCOSUR], Andean Community [ANCOM], Central American Common Market [CACM] and North America Free Trade Agreement [NAFTA]) on bilateral trade in 19 countries from the Western Hemisphere for the period 1970–2014. For this purpose we estimate different gravity models to control for trade creation and diversion, export diversification and intra-industry trade using OLS log-linearized gravity model and Poisson pseudo-maximum-likelihood panel data estimators that allow controlling for zero-value trade flows. We find trade creation for ANCOM, MERCOSUR and CACM and trade diversion for NAFTA and MERCOSUR countries. Export diversification negatively affects bilateral trade in all American agreements, while intra-industry trade has contributed to trade expansion in ANCOM and the opposite for NAFTA, MERCOSUR and CACM. Global supply chains may help us explain these results. Finally, we find anticipatory effects on trade several years before the signing of the agreements, but only NAFTA countries seem to be natural trading partners in the region while the rest of Latin American regional agreements have not resulted in a comprehensive, profound and consolidated common market.     

Regional Integration and Trade: Controlling for Varying Degrees of Heterogeneity in the Gravity Model

The proliferation of regional trade agreements (RTAs) in the 1990s prompted a renewal of interest in studying the effect of regional integration on trade. Using a panel dataset of bilateral export flows from 12 EU countries to 20 OECD trading partners over the period 1992–2003, the trade effect of European regional integration, denoted by an EU dummy, is examined across a number of fixed effects (FE) specifications, each of which has been claimed as the correct econometric specification of the gravity model. Typically parsimonious in (time‐varying) economic variables and abundant in fixed effects, the FE specifications allow for varying degrees of heterogeneity in the gravity model. Two gravity models are estimated: a gravity model of traditional trade determinants and a gravity model of new trade theory (NTT) determinants. Both gravity models provide reasonable coefficient estimates, although they vary somewhat across the FE specifications for the traditional gravity model. Both gravity models are congruent in suggesting that the coefficient of the EU dummy declines in magnitude and becomes insignificant as an increasing degree of heterogeneity is admitted into the model. This suggests the fundamental importance of the econometric specification when evaluating trade policy effects within a gravity framework.     

Financial Integration and Economic Growth in the COMESA and SADC Regions

Abstract

This study used panel data methods to examine the relationship between financial integration and economic growth in the COMESA and SADC regions. Using Foreign direct investment (FDI) and portfolio flows as a share of GDP, Chinn-Ito index of financial openness and debt flows as measures of financial integration, the study found that the relationship between financial integration and growth is largely insignificant in the combined sample of COMESA and SADC regions. However, the relationship changes when the two regions are separated. Whereas two of the indicators of financial integration are significant in the COMESA region, only one indicator of financial integration is significant in the SADC region implying that financial integration is more important in the COMESA region than in the SADC region. The results support the growth retarding theories of financial globalization and the convergence hypothesis in the COMESA region while the neoclassical trade theories find strong support in the SADC region. These results imply, first, that financial integration has different growth effects for different regional groupings and thus integration policies should not be universally applied. Second, these results imply that further enhancement of trade integration policies offer more promising outcomes for economic growth in the SADC region than financial integration policies while the converse is true for the COMESA region.     

Impact of RTA and PTA on Bangladesh’s Export: Application of a Gravity Model

As part of its growth strategy, Bangladesh instituted a trade liberalization process in the early 1990s which gained momentum in later years. Trade grew from 24.4 to 45% of GDP between 1980–81 and 2007–08, an indicator of increased liberalization as well as the growing importance of the external sector in Bangladesh. Apart from its unilateral liberalization, Bangladesh participates in three different regional trade agreements (RTAs): the South Asian Free Trade Agreement (SAFTA), the Asia Pacific Trade Agreement (APTA) and the Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation Free Trade Area (BIMSTEC FTA). In addition, Bangladesh signed preferential trade agreements (PTAs) with the member countries of the Developing 8 (D8). Because of the growing importance of RTAs, this study investigates their contribution to the export flows from Bangladesh using the gravity model that has become the primary tool for estimating the trade effects of regional integration. Regression results of bilateral exports for 40 countries from 1992–2009 indicate two crucial aspects. Firstly, all the RTAs consistently maintained statistically significant negative signs, except the BIMSTEC FTA and SAFTA, which showed insignificantly positive and insignificantly negative effects respectively. Secondly, the intensity of negative effects and the level of significance have shown a declining trend as the status of those blocs has changed from political or economic cooperation agreements to preferential agreements and from preferential agreements to free trade agreements. Thus, the intensity of tariff liberalization and the degree of sectoral coverage seem to be the important determinants of the RTAs’ performance. Therefore, experts expect that full-fledged implementation of FTA provisions and the elimination of all tariff and non-tariff barriers might result in a higher degree of integration.     

Possible Dynamic Effects of AFTA for the New Member Countries

We discuss the possible dynamic benefits of economic integration for the new members of ASEAN. Direct evidence on regional integration and growth is weak, but three indirect channels are possible. Openness increases access to foreign knowledge, which could help productivity growth. Trade liberalisation is likely to stimulate investment and might promote the integration of the regional production network. Binding liberalisation under AFTA would help ‘lock‐in’ and accelerate liberal economic reforms. These gains are not automatic, however. Discriminatory liberalisation will switch imports from sources with high stocks of knowledge towards ASEAN countries, which have lower stocks, and so may lower productivity growth. We term this ‘dynamic’ trade diversion. In addition, local absorptive capabilities must be developed to benefit fully from technology transfer. Finally, we recommend extending AFTA commitments on an MFN basis in order to avoid static and dynamic trade diversions.     

Supplementary Trade Benefits of Multi-Memberships in African Regional Trade Agreements

ABSTRACT

Few papers have investigated the trade effects of multi-memberships of Regional Trade Agreements (RTAs), but none has done this in an Africa-wide manner. This paper investigates the supplementary trade effects of multi-memberships of RTAs after controlling for single-membership for all African RTAs. We use (1) overall number of RTAs by country pair; (2) dummies of number of RTAs; and (3) number of RTA memberships by countries within each RTA grouping, in a panel of 53 African countries from 1995 to 2014. The gravity models are estimated with the Eicker-White robust covariance Poisson Pseudo-Maximum Likelihood (PPML) which is superior to previous ones. All the estimates concur that multi-memberships have significant additional intra-Africa trade benefits which increase with the number of memberships. The implication is that although RTAs enhance trade in Africa, it is only a second-best to a complete integration of the African continent. A complete dismantling of politically induced trade barriers and even inter-RTA boundaries within Africa will yield significant intra-Africa trade benefits. The results support the ongoing efforts in Africa in pursuing a “one Africa” vision. Such efforts have to transcend regional integration and pursue the ideal of an integrated Africa for the full trade benefits to be realized.     

An Analysis of Mercosur's Regional Trading Arrangements

After six years of stop‐start negotiations, Mercosur is no closer to signing a regional trading agreement (RTA) with the EU, whilst negotiations to finalise a Free Trade of the Americas Agreement (FTAA) have also stalled. This is due to various factors: economic crises in Mercosur, intransigence by member countries and uncertainty surrounding the outcome of the Doha Round. Estimates from the trade literature predict welfare gains to Mercosur from both RTAs whilst only one study assesses the additional benefits of removing non‐tariff barrier (NTB) trade costs which have remained largely unchallenged within the multilateral forum. In this paper, we improve the treatment of NTB estimates employing a theoretically consistent gravity specification, where calculated tariff‐equivalent estimates are subsequently implemented into a modified computable general equilibrium (CGE) model. Relative to a realistic baseline, and incorporating trade‐induced productivity and capital accumulation effects, we reassess the benefits of both regional initiatives to Mercosur, revisiting the claim that NTB trade cost abolition doubles the ‘standard’ welfare estimates. Contrary to previous studies, the results suggest that an FTAA yields greater gains to Mercosur than an EU RTA whilst the claim of Monteagudo and Watanuki (2003 ) pertaining to trade cost elimination is understated.     

亚太新双边主义兴起的原因研究——一个政治经济学的分析视角

亚太地区双边贸易协定的兴起与演进形成当代亚太区域经济合作发展的新阶段,其意义和影响日益受到国际社会的普遍关注。本文以政治经济学方法为分析工具,对亚太地区双边主义兴起的动因进行剖析和评价,指出亚太地区双边主义的形成是亚太地区各经济体在当前国际政治经济环境约束下,选择最大化自身利益的贸易政策的必然结果。中国应积极参与建立双边自由贸易区;发挥先发优势,谋求以我为主的区域经济一体化进程;协调国家战略与地区战略,平衡经济利益和政治利益。     

开放条件下贸易利益内涵的界定及其相关理论评述

长期以来,参与国际分工与贸易的各国是否能从国际贸易中获得利益这一问题,一直是理论界争论的焦点,因此,本文从狭义的贸易利益与广义的贸易利益,真实的贸易利益与潜在的贸易利益,贸易利益与地区经济一体化,贸易利益与不完全竞争、规模报酬递增四个角度作了一些评述。本文认为,只有在一定的条件之下,一国才可以从开放的国际贸易中获得贸易利益,最终实现一国经济持续增长的目标,如政府在开放经济条件下采取适当的贸易政策、在开放贸易情况下补偿受损人群的利益、参与区域经济一体化等。     

Varieties of regional integration,international trade networks and risk

This paper explores the relationship between regional integration models and trade network structures. The paper further investigates the implications of these trade relationship configurations on risk. The exploratory study models the European Union and the Association of Southeast Asian Nations as networks: countries in each region are nodes connected by lines representing commodity trade flows. The study compares the evolution of the two regional networks over a 25‐year period (1990–2014). The results confirm that different regional integration models lead to differently structured economic relationships. The findings show that loosely coupled networks are vulnerable to the failure of a few connected nodes (concentrated vulnerability), but that tightly coupled regional networks are vulnerable to the failure of any of its nodes (random vulnerability). These unique differences in vulnerability have critical implications for managing economic risk.     

International Trade Agreements and International Migration

Despite large potential economic gains, bilateral and multilateral negotiations focusing on liberalisation of migration have not shared the high profile of international trade negotiations and agreements. Migration and trade have been traditionally viewed rather separately and the relevance of the many, and complex, interdependencies has been given remarkably little attention in the literature to date. In this article, we focus on the two‐way interaction between international migration and agreements designed to enhance cross‐border trade and investment. Liberalisation of international trade in services and in the movement of people potentially offers much greater economic gains than liberalisation of remaining barriers to goods trade. However, progress within multilateral frameworks is fraught with difficulty. The World Trade Organization’s General Agreement on Trade in Services (GATS) has yielded little real progress so far and negotiations within more flexible unilateral and bilateral frameworks are likely to be more successful in liberalising the movement of labour. We discuss a range of specific examples, focusing particularly on the interesting case of New Zealand. We find that trade agreements are increasingly including agreements on migration, though typically favouring temporary migration and involving numerically modest quotas. We conclude that migration regulatory frameworks are likely to be further and more strongly linked to trade and investment agreements in the future, particularly given changing economic and demographic forces. The primary focus of migration policies may nonetheless remain different from that of trade policies. While further migration liberalisation is likely to be through bilateral and regional agreements, it will be important to try to lock in the gains of such agreements, while simultaneously working to consolidating these in a way that will help to facilitate future multilateral agreement.     

中国自贸区的经济增长效应评估--基于沪津闽粤自贸区的实证研究

为考察中国自贸区对地区经济增长的效应,结合1995~2018年省级面板数据,采用双重差分法实证评估了自贸区带来的经济增长效应,并在此基础上进一步用合成控制法检验了自贸区经济增长效应的地区异质性,研究发现:第一,自贸区对区域经济增长具有显著持续的推动作用,且设立时间越久,推动作用逐渐增强;第二,影响机制检验结果表明,自贸区主要是通过扩大贸易水平和吸引外商投资的方式促进经济增长,通过产业结构优化升级的途径还未得以充分发挥;第三,自贸区经济增长效应存在地区异质性,上海、广东、福建的自贸区对地区经济增长推动作用显著,天津自贸区的经济增长效应相对不明显。     

Putting Canada in the penalty box: Trade and welfare effects of eliminating North American Free Trade Agreement

Three years ago, very few economists would have imagined that one of the newest and fastest growing research areas in international trade is the use of quantitative trade models to estimate the economic welfare losses from dissolutions of major countries' economic integration agreements (EIAs). In 2016, "Brexit" was passed in a UK referendum. Moreover, in 2019, the existence of the entire North American Free Trade Agreement (NAFTA) is at risk if the US withdraws—a threat President Trump has made if the proposed US–Mexico–Canada Agreement is not passed by the US Congress. We use state‐of‐the‐art econometric methodology to estimate the partial (average treatment) effects on international trade flows of the six major types of EIAs. Armed with precise estimates of the average treatment effect for a free trade agreement, we examine the general equilibrium trade and welfare effects of the elimination of NAFTA (and for robustness US withdrawal only). Although all the member countries' standards of living fall, surprisingly the smallest economy, Mexico, is not the biggest loser; Canada is the biggest loser. Canada's welfare (per capita income) loss of 2.11% is nearly two times that of Mexico's loss of 1.15% and is nearly eight times the US' loss of 0.27%. The simulations will illustrate the important influence of trade costs—international and intranational—in contributing to the gains (or losses) from an EIA's formation (or elimination).

ASEAN-India Free Trade Agreement: Evaluating Trade Creation and Trade Diversion Effects

The present study attempts to provide insight into the trade creation and trade diversion effects of ASEAN-India Free Trade Agreement in goods, which came into force in 2010. The paper applies a theoretically consistent gravity model and uses empirically robust procedures such as ordinary least squares and pseudo-Poisson maximum likelihood in order to analyze the ex post effects of the agreement at an aggregate level. The results reveal that standard gravity variables are statistically significant and report expected signs, yet a reduction in export flows has been observed following the implementation of the free trade agreement, giving rise to pure trade diversion effects.     

Trade creation and diversion effects in the Mediterranean area: Econometric analysis by gravity model

Since the early 1990s, the world has seen a proliferation of free trade agreements (FTAs). A major goal of free trade is to develop trade between its signatories. The gravity model is used to analyze the bilateral trade data against the variables of the relative size of the pair of countries involved in trade, distance, common border and language and dummies for each of the FTAs. This article focuses on the studying of the influence of the FTAs in the Mediterranean countries in which we integrate the role of the regional dummy EU-15, Economic and Monetary Union (eurozone), the Arab Maghreb Union and AGADIR Agreement (FTA between Jordan, Egypt, Tunisia and Morocco) in trade flows. In addition, this work aims to detect the impact of the global financial crisis on export flows between the FTAs in the Mediterranean region. The use of regional variables in gravity models designed to determine whether the FTAs contribute to the creation or trade diversion. This study examines a cross section and panel (static and dynamic) of 27 countries for 1980–2011. The results show the existence of a strong relationship between the factors of FTAs and trade flows.     

Do deeper regional trade agreements enhance international technology spillovers?

We examine whether regional trade agreements (RTAs) enhance international technology spillovers using a panel of patent citation data for 114 countries/regions for the period 1991–2007. We use patent citations as a proxy for technology spillovers. The focus of this study is on whether the depth of regional integration matters for technology spillovers among member countries/regions of RTAs. The depth of integration is measured by the extent to which an RTA includes legal obligations outside the current mandate of the World Trade Organization. We find that the depth of integration actually influences technology spillovers and that a deeper integration in a broad sense has a greater impact on technology spillovers than do technology‐related provisions.
