Cette thèse a pour objet d'examiner cinq aspects de la relation entre le commerce Sud-Sud et la « nouvelle » géographie du commerce international en portant une attention toute particulière aux liens qui existent entre les BRICs (Brésil, Russie, Inde, Chine) et l'Afrique sub-Saharienne (ASS) puis entre la Chine et l'ASS. La première partie s'attache à démontrer certaines caractéristiques relatives à la mutation des relations commerciales Sud-Sud. Dans le premier chapitre, l'hétérogénéité au sein même des BRICs est confirmée à partir d'un certain nombre de facteurs explicatifs des flux commerciaux bilatéraux avec l'ASS. Dans le second chapitre, les flux commerciaux Sud-Sud semble jouer un rôle déterminant dans la diversification géographique du commerce intra-Africain en termes de nouveaux partenaires commerciaux. Dans le troisième chapitre, l'idée d'une réorientation du commerce des ex-colonies depuis l'indépendance vers la Chine au détriment des anciennes puissances coloniales a été validée empiriquement. Quant à la deuxième partie, elle s'intéresse aux liens entre la politique économique extérieure et le commerce Sud-Sud. Les résultats du quatrième chapitre soulignent l'impact significatif de la « politique de la Chine unique » sur les flux commerciaux chinois et taiwanais par le biais de la diplomatie économique. Les estimations du cinquième chapitre confirment l'hétérogénéité des effets moyens et dans le temps des accords régionaux africains sur les échanges commerciaux selon la nature des partenaires, la forme des accords commerciaux ainsi que leur chevauchement. / This thesis emphasises five aspects of relations between South-South trade and « new » geography of international trade. We particularly pay attention to the links between BRICs (Brazil, Russia, India, China) and sub-Saharan Africa (SSA) but also between China and SSA. The first part attempts to demonstrate some characteristics concerning the mutation of South-South trade relations. In the Chapter 1, the heterogeneity of BRICs is confirmed from some factors of bilateral trade flows with SSA. In the Chapter 2, the South-South trade flows play a significant role in the geographic diversification of intra-African trade in terms of new trading partners. In the Chapter 3, the assumption of a trade reorientation of ex-colonies since independence with China at the expense of former colonial powers has been empirically validated. The second part studies the linkages between the foreign economic policy and South-South trade. The findings of the Chapter 4 highlight the significant impact of the « One China policy » on Chinese and Taiwanese trade flows through the economic diplomacy. The estimates of the Chapter 5 confirm the heterogeneous average effects but also over time of the African trade agreements on trade according to the nature of trading partners, the kinds of trade agreements and their overlapping.

Though the strategic importance of regional economic integration to multinational companies (MNC) has been researched extensively internationally, this concept has not been studied in South Africa. In fact, there is a growing nostalgia that with the South African Development Community (SADC) moving towards its set macroeconomic convergence targets; regional economic integration eventually leads to macroeconomic stabilisation. This ultimately becomes the root of growth in a region that has been severely affected by globalisation, financial crises, increasing government debt and budget deficit problems. This study, hence, tries to find out how the critical decisions of South African MNCs are made when operating within regional markets. Consequently, statistical econometric models were developed to test time-series data from 1980-2011 using the best (most efficient) linear unbiased estimator (BLUE) ordinary least square regression technique. An analysis was then done to investigate how South African firms have been able to gain maximum benefits by adopting the SADC as its major trading bloc in Africa. The study’s findings showed that the major barriers that impede MNCs of South African origin from penetrating these markets were custom duties, direct and indirect tariffs. It was observed that this would only be reduced by regional integration. Determined to critically interrogate the problems detailed in this research, three hypotheses were tested, analysed and subsequent interpretation of the findings revealed that South African MNCs contribute positively to regional economic growth and investment in the SADC. Furthermore, the study found out that although these factors were important, they were not the only variables that stimulated the competitiveness of South African MNCs in the SADC region. The literature review sections of this study found that the adoption of strategic management initiatives by MNCs improved the operation of transnational companies in South Africa. A comparison between the value of South African MNCs, as well as, other explanatory variables, and the Gross Domestic Product (GDP) of both South Africa and the SADC using time series data for the period 1980-2011 indicated that there was a positive relationship between the contribution of MNCs to South Africa’s economy and the GDP of both South Africa and the SADC. This proved that there is a significant link between MNC growth and national/regional productivity. In conclusion, the study established that the findings of the literature review were theoretically in sync with the empirical analysis. Also, the outcome of this study concurred with the findings of similar research. In essence, regional trade arrangements are an increasingly important element of the global trade environment, of which the move by South Africa’s MNCs to operate in the SADC market was a positive one. Finally, the study found out that for these firms to be successful in the international business arena, business management decisions need to be made, only after a detailed strategic analysis of the significance of regional economic integration is considered. This integrative framework certainly determines the operational efficiency, survival and profitability of most MNCs that operate within the region. / Business Management / M. Admin.

Dans cette thèse, nous étudions l'effet de la répartition inégale des ressources naturelles entre les pays sur trois aspects principaux. Dans le premier chapitre, nous examinons empiriquement les effets asymétriques potentiels de l'adhésion à l'Organisation Mondiale du Commerce (OMC) entre les membres, en nous concentrant spécifiquement sur les pays en développement. Les résultats suggèrent que l'adhésion à l'OMC a contribué à l'augmentation des exportations de tous les pays, à l'exception des pays non-émergents riches en ressources. En revanche, les pays émergents riches en ressources sont les plus grands bénéficiaires de l'accession à l'OMC. Dans le deuxième chapitre, nous explorons empiriquement l'impact de la dotation en ressources naturelles sur les gains de six Accords Commerciaux Régionaux (ACR) entre les membres à travers trois axes : la complémentarité entre les pays, la diversification des pays riches en ressources ainsi que la création et le détournement des échanges. Nous concluons que la complémentarité entre les pays riches et les pays pauvres en ressources a été atteinte dans les accords de l’ECOWAS, du SADC et du CIS. Les résultats indiquent également que, dans tous les ACR, les pays riches en ressources ont accru leurs exportations hors secteurs des ressources naturelles et diversifié ainsi leurs structures d'exportation, en particulier avec les partenaires régionaux. En outre, dans la plupart des ACR, les pays pauvres ont accru leurs exportations vers leurs partenaires riches en ressources, tandis que ces derniers souffrent du détournement des échanges en termes d'importations. Dans le dernier chapitre, nous étudions l'impact de la dotation en ressources naturelles sur le processus de convergence entre les pays du PAFTA. Premièrement, les résultats démontrent que la sigma-convergence n'était observable qu'entre 1970 et 1990 dans les pays du PAFTA. De plus, l’estimation révèle que les ressources naturelles sont l'un des principaux déterminants de la convergence conditionnelle au sein du PAFTA. Par conséquent, l'asymétrie entre les pays en termes de dotation en ressources naturelles n'a pas empêché la convergence dans le PAFTA. L'analyse de la convergence des clubs a identifié trois principaux clubs parmi les pays du PAFTA. En outre, les facteurs qui ont déterminé la formation des clubs sont les ressources naturelles, la qualité des institutions et l'investissement. Par ailleurs, une abondance de ressources naturelles n'est pas suffisante pour être le meilleur club, mais doit être accompagnée d'institutions de qualité. / In this thesis, we examine the effect of the unequal distribution of natural resources between countries on three main aspects. In chapter one, we empirically examine potential asymmetric effects of the accession of the World Trade Organization (WTO) across members, focusing specifically on the developing countries. The results suggest that membership in the WTO contributed to greater exports for all countries, except for non-emerging resource-rich countries. In contrast, emerging resource-rich countries are the greatest beneficiaries from the accession of the WTO. In chapter two, we empirically explore the impact of natural resource endowments on the gains of six Regional Trade Agreements (RTA) across members through three axes: complementarity between countries, diversification of resource-rich countries, and trade creation and diversion. We conclude that the complementarity between resource-rich and resource-poor countries has been achieved in the ECOWAS, SADC and CIS agreements. The results also indicate that in all RTAs, the resource-rich countries increased exports in non-natural resource sectors and thereby diversified their export structures, especially with regional partners. Moreover, in most RTAs, poor countries boosted their exports to resources-rich partners, while resource-rich countries suffer from trade diversion in terms of imports. In the last chapter, we study the impact of natural resource endowments on the process of convergence among PAFTA countries. First, the results demonstrate that sigma-convergence was only observable between 1970-1990 among PAFTA countries. The estimation reveals that natural resources are one of the main determinants of conditional convergence within PAFTA. Therefore, the asymmetry between countries in terms of natural resource endowment did not impede the convergence in PAFTA. Club convergence analysis identify three main clubs among PAFTA countries. In addition, the factors that determined clubs’ formation are natural resources, quality of institutions, and investment. Further, an abundance of natural resources is alone not enough to be the best club, but must be accompanied by high-quality institutions.

Les « trois organisations soeurs », à savoir la Commission du Codex Alimentarius (CCA), l’Organisation mondiale de la santé animale (OIE) et la Convention internationale pour la protection des végétaux (CIPV), et les mesures sanitaires et phytosanitaires de l’ASEAN maintiennent une relation mutuellement étroite et des rapports d’interactions complexes et multidimensionnelles, rapports qui peuvent affecter des flux d’activités d’importation et d’exportation de produits agro-alimentaires réglementées surtout par le droit international économique. En envisageant le droit comme processus de décisions, particulièrement le droit international comme processus de communication entre les différents participants de la « communauté mondiale », ces rapports peuvent être mieux identifiés et compris à tous les niveaux : multilatéral, régional, bilatéral et national. Compte tenu de l’intensité et de la fréquence des échanges et du caractère fortement interdépendant du monde d’aujourd’hui, les « trois organisations soeurs » et leurs normes, directives et recommandations sont susceptibles de jouer divers rôles dans la promotion d’une plus grande production et d’un plus large partage des valeurs fondamentales recherchées par l’humanité entière, soutenues par la « New Haven School of International Law ». Non seulement s’agit-il des rôles liés à l’augmentation de l’efficacité du processus de réduction de barrières commerciales résultant des mesures SPS protectionnistes, mais aussi de ceux qui sont peu soulignées et qui se précisent suite aux pratiques répétées des décisionnistes de l’ASEAN. Ce sont notamment les rôles en tant qu’inducteurs de performance pour les mécanismes d’encadrement de mesures SPS, afin de s’assurer que celles-ci sont raisonnables par rapport à chaque contexte spécifique et respectueuses de la dignité humaine ; en tant que catalyseurs du régionalisme ouvert ; et en tant que promoteurs de la dimension du développement dans les accords commerciaux régionaux de l’ASEAN. / The « three sisters », namely the Codex Alimentarius Commission (CAC), the World Organisation for Animal Health (OIE) and the International Plant Protection Convention (IPPC), and SPS measures of ASEAN maintain a mutually close relationship and can interact with one another in complex and multidimensional ways, which can affect flows of import and export activities of agro-food products regulated especially by international economic law. By perceiving law as a process of decisions, and particularly international law as a process of communication among different participants of the « world community », these interactions can be better identified and comprehended at all levels : multilateral, regional, bilateral and national. Considering the intensity and frequency of exchanges and the strong interdependency of today’s world, the « three sisters » and their standards, guidelines and recommendations are likely to play numerous roles in promoting a greater production and wider distribution of fundamental values that all human beings desire to maximize and achieve, as defended by the « New Haven School of International Law ». Not only are these roles related to the promotion of a more efficient process of eliminating trade barriers deriving from SPS protectionist measures, but also those which are insufficiently highlighted, yet becoming more obvious through repeated practices of ASEAN decision-makers. These are notably the roles of the « three sisters » as performance drivers for monitoring mechanisms of SPS measures with a view to ensuring that they are reasonable in each specific context and respectful towards human dignity; as catalysts of open regionalism ; as promoters of the development dimension in regional trade agreements concluded by ASEAN.

Since the Asian Financial Crisis of 1997 and the Global Financial Crisis of 2007, members of the Association of Southeast Asia Nations (ASEAN) have sought to strengthen ASEAN's regional economies through a digital trade project known as the ASEAN Single Window (ASW). The purpose of this case study was to explore the business strategies that multinational organizational leaders used to overcome business barriers while implementing ASEAN partnership contracts and ASW region-wide projects. This study may be unique in that, at the time of this research, there was no published study in which researchers had explored a single window for a vast, multination geographical region. Data collection was done via in-depth interviews with ASW executives, studying online ASW-related conferences, and examining relevant strategic documents. A 6-phase thematic analysis process based on methodological triangulation corroborated the data and addressed construct validity through data familiarization, generating initial coding, categorizing codes and searching for themes, breaking codes into subcategories, data reduction and defining and naming themes, and report generation. The 4 strategic themes that emerged were business models and processes, public-private partnerships, project management methodologies, and overlapping themes. The findings offer insights into ways to overcome the ASW's constraints and barriers. These strategic themes developed into a list of critical success factors and a summary list of principle business strategies and best practices. The implication for social change is a regionally collaborative trading environment providing potential economic options that not only impede the deterioration of the regional social fabric but support new opportunities such as trade liberalization and economic stability.

1990年代以來，區域貿易協定的數目呈現倍數成長，發展到今日，全世界已約有230個FTA。然而臺灣卻因政治因素被屏除在區域經濟整合之外，將為臺灣經濟帶來諸多挑戰，我國若欲走出困境、強化在國際間的競爭力，勢必要有所作為。因此馬英九總統在競選總統時就以「與世界連結，參與全球區域經濟整合」為經貿政策主軸，而充分利用中國大陸現有的資源與市場，與其簽署區域貿易協定更是最具關鍵性的一步。經過多次正式與非正式的溝通協調，2010年6月29日，兩岸正式在重慶簽署ECFA，並於同年9月12日正式實施。 但從ECFA議題拋出到簽署實施，各界的爭辯從未停止，究竟ECFA對臺灣是危機還是轉機？是幫助臺灣走向世界還是被鎖進中國？值得深入研究，因此本文藉由國內外相關文獻來探討簽署ECFA對我國政治、經濟社會以及國家安全層面的影響，以增加閱讀者對ECFA的了解，也能成為政府推動ECFA的參考。 / Since 1990s, the number of the region trade agreements has been doubling, and until now there has been a total of 230 FTAs around the world. However, due to political factors, Taiwan has been dismissed outside the regional economies conformity, which will bring many obstacles toward the economic development in Taiwan. If our country intends to walk away from the dilemma and raise our competiveness, some steps must be taken. Therefore, while running for the presidency, President Ma Yingjiu brought up, 〝Links with the world, participates in the whole world regional economies conformity〞 as his economics and trade policy. By fully making using at the mainland China’s existing resources and markets, it was a must for Taiwan to sign the region trade agreement with china. After several official and unofficial communication and coordinating, on June 29, 2010, the Cross-Strait ECFA was signed officially in Chongqing, and implemented in the same year on September 12. Nevertheless, since the ECFA was carried out and signed, the debates from all walks of life has never come to an end. Is ECFA a crisis or a turning point for Taiwan？ Does it the help Taiwan to move toward the world or to be locked within China？It is worthwhile to conduct a research to clear out the doubts. This article dims to take a deeper look at how ECFA is influenced on Taiwan n terms of politics, economy, and national security. So that not only can the readers have a better understanding of the ECFA but also the government refers to it while the implementation of policy.

<p>This research paper pays particular attention to the EAC because of its unique composition of four LDCs46 and 1 DC47 and the fact that three of these countries are landlocked least developed countries (LLDCs).48 The EAC was notified as a RTA to the WTO under the Enabling Clause on 9 October 2000 and registered as a Custom Union49 under WT/COMTD/N/14.50 The notification of the EAC under the Enabling Clause is due to the nature of composition of members therein and to the fact that the Enabling Clause does not require regional trading arrangements to cover substantially all trade, or to achieve free trade in the bloc within ten years after notification. Additionally, it provides an avenue for giving special consideration to the LDCs through making concessions and contributions,51 allows automatic exemptions from MFN (non-discrimination) treatment in favour of DCs,52 and thus allows other WTO members to accord more favourable treatment to DCs in many cases without according the same treatment to other WTO members.53.</p>

<p>The rapid growth in the number of regional trade agreements (RTAs) has led to concern about the weakening of the multilateral trading system. This thesis examines the spread of such agreement and the extent to which they pose a threat to the multilateral system. Regionalism and multilateralism are complimentary as shown in the case study of the East African Community. The current regional trade agreement management rules are weak and ambiguous and possible amendments for these rules are proposed</p>

La scelta del modeller riguardo alla chiusura del modello CGE influenza i suoi risultati finali e le sue prescrizioni di policy. In questa tesi, lo scopo è l’analisi e l’identificazione del problema, sia attraverso una discussione teorica che un’ applicazione pratica. Dall’articolo del 1963 di Amartya Sen in poi, la letteratura ha presentato vari articoli sull’argomento. Attualmente, il problema delle chiusure del modello non appare più centrale nel dibattito. Dopo una breve introduzione su cosa siano i CGE, il loro sviluppo e la loro struttura, è presentata una serie di esemplificative maquette con lo scopo di introdurre al concetto di chiusura, come essa influenzi i risultati e come questa scelta del modeller sia intimamente connessa ai fondamenti macroeconomici del sistema. Dopo la teoria, ci si sposta nel mondo reale analizzando con differenti modelli (Neoclassico, “Bastardo Keynesiano”, Strutturalista/Post- Keynesiano) e diverse chiusure per gli aggregati macroeconomici (risparmi privati, pubblici, e stranieri) l’impatto dell’accordo regionale SADC sull’economia mozambicana. I modelli CGE per il Mozambico sono calibrati su una SAM del 2003 e sono svolti con l’ausilio di GAMS/MPSGE. I risultati dimostrano che la chiusura influenza i risultati stessi del modello per cui ognuno presenta una serie di raccomandazioni politiche per l’applicazione dell’accordo SADC. / Modellers’ choice on closure rules affects a CGE model results and consequently its policy prescriptions. In this thesis, the aim is to detect and assess this issue, both through a theoretical discussion and an empirical application. Starting from Amartya Sen’s 1963 paper, literature presents many contributions on this topic. Currently, the closure rule problem is not central in the CGE debate. After a brief introduction on CGEs, their development and their structure, a series of simple maquette is presented. They have the exemplary role of introducing the concept of closures, explain how they affect final outcomes and how this modeller’s choice is strictly connected to the macroeconomic foundation of the economic system. After theory, we move into the real World analyzing through different models (Neoclassical, “Bastard Keynesian”, and Structuralist/ Post- Keynesian), and through different closure rules for macro- aggregates (private, public and foreign savings) the impact of the Regional Trade Agreement of SADC with respect to the Mozambican economy. The Mozambican CGE models are calibrated on a 2003 Social Accounting Matrix (SAM) and they are performed using GAMS/ MPSGE. Outcomes show that closure rules affect them and each model presents a set of policy prescription to implement the SADC agreement.
