No / The existing literature treats advanced technology sourcing as the only cause of reverse productivity spillovers from local to foreign firms and implies that mutual spillovers between foreign and local firms can only happen in the developed world. This paper argues that the diffusion of indigenous technology and local knowledge helps the productivity enhancement of multinationals, so that there can be mutual spillovers even in a developing country. The results from a large-sample firm-level econometric analysis and a comparative case study of seven companies in Chinese manufacturing support this new argument, as mutual spillovers are identified between local Chinese firms and overseas Chinese or OECD-invested firms.

Yes / We study the role of the strength of Intellectual Property Rights (IPR) law protection and enforcement in influencing horizontal productivity spillovers from inward FDI to domestic firms in host countries. While most WTO countries adopted strong IPR legislation due to exogenous pressure resulting from the signing of the Trade-Related Aspects of IPR (TRIPS) agreement, public IPR enforcement strength continues to vary significantly between countries. We meta-analyse 49 studies and find that public IPR enforcement strength has a direct positive effect on horizontal productivity spillovers from inward FDI to domestic firms and a negative moderating effect on the relationship between IPR law protection strength and horizontal productivity spillovers from inward FDI to domestic firms.

Yes / This study estimates output market power in the Chinese banking industry using the multi-output Lerner index. We propose a minimum distance cost function approach, which allows us to determine not only the level of market power but also the non-profit maximizers and efficiency level of Chinese banks. Following the first-stage analysis, we employ the generalized method of moment system estimator to evaluate the impacts of bank innovation and trade openness on market power in a multi-output banking context. In particular, we innovatively propose a causal structure analysis based on Wang and Blei (2019) to validate and verify the robustness of our results. We also assess this relationship for different types of bank ownership in China. The findings suggest that Chinese banks exhibit high market power in loans. Furthermore, the results show that bank innovation and trade openness have a significant negative impact on market power in loans, but a significant positive impact on market power in securities. The results also indicate a significantly negative impact of trade openness on overall market power. We find that higher levels of innovation among state-owned and joint-stock commercial banks improve the overall level of market power. The results suggest that, for all bank ownership types, trade openness has a significant negative impact on market power in loans but a significant positive impact on market power in securities. The impact on the overall level of market power is consistently significant and negative. / The full-text of this article will be released for public view at the end of the publisher embargo on 11 Aug 2025.

India is fast becoming one of the largest economies worldwide, with expectations of becoming the second largest economy by 2050. The growth this country is demonstrating is accompanied by integration with other economies with active engagement in trade and investment in the world economy. Analysts and researchers strive to understand the possible effects of the rise of India on the global economy. The influence of India’s rise on Africa is an arguable topic. The Indo-Africa relationship has a strong political and socio-economic history. This relationship has undergone some changes since 1990 when India started a new approach that included internationalisation. In the modern economy the trade and investment from India to Africa have illustrated fast growth rates. It is claimed that India’s main interest in Africa is to gain access to Africa’s abundant resources with the intention of supporting its economic growth. This creates some concern on the nature of India’s involvement in Africa; whether or not it will increase the development and whether it will put pressure on Africa’s control of its resources. This study focuses on understanding the extent of Indian FDI in Africa and the factors that determine this involvement. Africa is known as the poorest continent worldwide; hence the development should be managed and controlled in order to sustain the growth. The flows of FDI to this continent can provide some advantages that include growth and development, while FDI can also prompt some disadvantages such as resource extraction. Profiling the determinants of Indian FDI in Africa provides an understanding of the influence India may have on Africa. Profiling the determinants of Indian FDI in Africa is done by means of a literature study that identifies the determinants that are applicable to African FDI. These determinants include natural resources, market size, political instability, macro-economic instability, weak policies, inflation, good governance, investment, GDP, growth, openness and oil production. Following the literature study an analysis is done on the trend of FDI worldwide and especially between India and Africa. The overall amount of FDI flows illustrates large increases globally and developed regions account for the majority of FDI flows. The trends of flows illustrate some changes that highlight the prominent role developing countries are starting to play. Africa is classified as a developing region that accounts for a fairly small amount of the total flows to the developing regions. It is noted that Africa’s share is steadily increasing and is expected to keep on rising. Indian FDI to Africa has demonstrated some staggering increases, while India claims to further increase its involvement. India’s FDI mainly flows to the resource sectors such as oil, coal and gas. India also states to expand its FDI involvement into African sectors such as the infrastructure, information technology, computer software, services and telecommunication. Identifying the specific determinants of Indian FDI in Africa is established by estimating models using the Structural Equation Method (SEMs). A combination of a factor analysis and regression analysis is estimated. The specific determinants that influence Indian FDI in Africa include government effectiveness, control of corruption, crude oil price, school enrolment and exports. The level or value of the investments is influenced by the government effectiveness and rule of law. This study concludes that India’s involvement in Africa is increasing. India demonstrates high levels of interest in Africa’s resources, but this is prone to expand across different sectors. / MCom (International Trade), North-West University, Potchefstroom Campus, 2013

Cette thèse analyse les stratégies des firmes multinationales dans leurs différentes dimensions et évalue leur effet sur les consommateurs et travailleurs. Les essaies consécutifs s'intéressent aux choix d'expansion des FMNs, leur décision de délocalisation de production, leurs stratégies de l'investissement direct à l'étranger (IDE) au niveau agrégé, ainsi que les pratiques de la discrimination de prix sur les marchés aux fortes inégalités de revenu. / This thesis examines both theoretically and empirically strategies of multinational firms in their various dimensions and evaluates their impact on consumers and workers. The following essays look at MNEs' product expansion choices, their production localization decisions, foreign direct investment strategies (FOI) at the aggregate level and, finally, price discrimination practices on more unequal markets.

Abstracts in English, Afrikaans and Zulu / This study attempts to analyse the key FDI determinants in African countries using annual data for the period from 2003 to 2015. It firstly, gives the introduction and the background of FDI. Secondly, it provides both theoretical and empirical literature review on the key FDI determinants. Based on the literature review, the pre-estimation diagnostics (correlation analysis, descriptive statistics and mean and overall mean analysis), panel root tests, panel co-integration tests, main data analysis (fixed effects, random effects, pooled OLS, fully modified OLS and dynamic GMM) and robustness tests using the lagged variable approach were conducted to analyse the key FDI variables. Main data analysis indicated that the lag of FDI had a significant positive impact on FDI. The empirical results revealed that human capital development, infrastructure, growth rate, trade openness, natural resources, financial development, unemployment, exchange rate, government final consumption expenditure and population are the key FDI determinants in African countries. The robustness tests using the lagged variable approach were estimated to analyse if there is a causal relationship FDI and other variables such GDP, random effects revealed that there is uni-directional causality from GDP growth to FDI. Additionally, FDI was found to have been negatively but non-significantly affected by economic growth under the pooled OLS. / Hierdie studie poog om die sleuteleterminante van buitelandse direkte investering (BDI) in Afrikalande te ontleed deur gebruikmaking van jaarlikse data vir die tydperk 2003 tot 2015. Eerstens stel dit BDI bekend en verskaf ’n agtergrond daarvoor. Tweedens bied dit sowel ’n teoretiese as empiriese literatuuroorsig van die belangrikste BDI-determinante. Op grond van die literatuuroorsig is die volgende uitgevoer om die belangrikste BDI-veranderlikes te ontleed: voorskattingsdiagnostiek (korrelasieontleding, beskrywende statistiek en ontleding van gemiddelde en algehele gemiddelde), paneelworteltoetse, paneelkoïntegrasietoetse, hoofdataontleding (vaste effekte, ewekansige effekte, saamgevoegde gewone kleinste kwadrate [GKK], volledig gewysigde GKK en dinamiese veralgemeende momentemetode [VMM]) en robuustheidstoetse deur gebruikmaking van die gesloerdeveranderlike-benadering. Hoofdataontleding het aangedui dat die naloop van BDI ’n beduidende positiewe uitwerking op BDI het. Die empiriese resultate het aan die lig gebring dat mensekapitaalontwikkeling, infrastruktuur, groeikoers, handelstoegang, natuurlike hulpbronne, finansiële ontwikkeling, werkloosheid, wisselkoers, die staat se finale verbruiksbesteding en bevolking die belangrikste BDI-determinante in Afrikalande is. Die robuustheidstoetse deur gebruikmaking van die gesloerdeveranderlike-benadering het ten doel gehad om te ontleed of ’n kousale verband tussen BDI en ander veranderlikes soos BBP bestaan. Ewekansige effekte het getoon dat daar eenrigtingkousaliteit van BBP-groei na BDI is. Daarbenewens is bevind dat BDI negatief maar niebeduidend geraak is deur ekonomiese groei ingevolge die saamgevoegde GKK. / Lolu cwaningo luzama ukuhlaziya izinto ezinquma ngotshalo-mali lwamanye amazwe oluqonde ngqo olwaziwa ngokuthi yi-foreign direct investment (FDI) emazweni ase-Afrika ngokusebenzisa idata yonyaka yesikhathi sokusukela ngo 2003 ukuya ku 2015.

South Africa is in need of foreign direct investment (FDI) to increase economic growth and alleviate unemployment and poverty. To succeed in obtaining this FDI, South Africa must compete with the rest of the world for the available FDI. The global economic outlook is currently still uncertain and the growth of advanced economies are slowing down while Asia and Sub-Saharan Africa continue to grow at a steady pace. South Africa, as part of Sub-Saharan Africa, should take advantage of this growth on the African continent as well as internationally. Although studies have been performed to ascertain the tax policies of countries, the role of taxation applied by countries and the effects of taxation on FDI, there have been few studies on the tax policies specifically in respect of withholding taxes on interest. The new South African withholding tax on interest, applicable to South African source interest payments to non-residents, has been proposed to be included in terms of sections 49A to 49H in the Income Tax Act (58 of 1962) and will become effective from 1 January 2015. These sections have been introduced to align the said withholding tax and the section 10(1)(h) interest exemption, applicable to normal income tax in respect of non-residents, to the withholding taxes on interest and interest exemptions applied globally. Attention should be focused on whether the aforementioned global alignment will be achieved with the introduction of this legislation as South Africa had previously applied a similar legislation called non-residents’ tax on interest (NRTI) which appeared to be unsuccessful. Determining whether this legislation has been aligned with global practice will provide useful insight into whether this new legislation will promote, stagnate or be indifferent to FDI in South Africa, while at the same time not eroding the tax base with overly generous exemptions. This study reviews and compares the taxes implemented globally specifically in relation to withholding taxes on interest in a selection of countries, namely the developing countries Brazil, Russia, India, China, Mozambique and Namibia and the developed countries Germany and Denmark. Other determinants which will also have an impact on the comparisons of these withholding taxes are, for example, normal and withholding tax interest exemptions and repo rates – all of which have been incorporated into this comparative study. Based on the literature reviewed and the comparative analysis, the study concludes that the South African withholding tax on interest is effectively designed to keep attracting foreign lending in order to remain competitive in international markets. It is further shown that the South African legislation in respect of the section 10(1)(h) blanket interest exemption is aligned to that of global practice. / MCom (South African and International Taxation), North-West University, Potchefstroom Campus, 2014
