Firm's Absorptive capacity: the case of Vietnamese manufacturing firms

Absorptive capacity is an essential factor for the development of any firm. Hence, numerous researchers use it when proposing different approaches and measurements. However, due to the ambiguity of definition of absorptive capacity, some studies focused on the within-firm aspects of absorptive capacity while some looked at the inter-firm aspects. Consequently, there are several proxies for absorptive capacity, which are unlikely to reach an agreement. Therefore, this study aims for the simplified measurement by defining the absorptive capacity of a firm as the gap in persistent efficiency between the firm and the best foreign firm in the same industry. The persistent efficiency of a firm is estimated by using single stage maximum likelihood method. This measurement is applied to the case of Vietnamese manufacturing firms from 2007 to 2015 to estimate the domestic absorptive capacity. The results show that domestic firms in the manufacture of tobacco products sub-sector have the best absorptive capacity and the manufacture of beverages sub-sector have the worst one. Finally, the validity of the proxy is confirmed when the study finds the positive correlation between absorptive capacity and a firm's age, size, technology level and skills of its workers.[IGA/FaME/2018/019 FDI

Technical efficiency of FDI firms in the Vietnamese manufacturing sector

The study examines technical efficiency of Foreign Direct Investment (FDI) firms in the Vietnamese manufacturing sector by applying stochastic production frontier model and making use of cross-sectional data in the period 2009-2013. The average level of technical efficiency of FDI firms is about 60% and it is higher than that of domestic firms (including private firms and state-owned firms). In addition, the study also analyses correlation between technical efficiency of FDI firms and other factors. It finds that there are positive correlations between FDI technical efficiency and net revenue per labour, firm's age or export activities in 2013. However, the study is unable to find evidence of a relationship between FDI technical efficiency and infrastructure or firm's investment activities. © 2016 by Hoang Duong Vu

Provincial foreign direct investment absorptive capacity of Vietnam

Objective: The objective of the article is to examine the importance of absorptive capacity in the relationship between foreign direct investment and economic performance in 63 Vietnamese provinces from 2007 to 2015. Research Design & Methods: The absorptive capacity at provincial level includes six components tested by confirmatory factor analysis, which allows for the argument that absorptive capacity of domestic firms is an important component of absorptive capacity of provinces. Besides this one, there are five other components, including financial development, human capital, the level of openness, the absorptive capacity of domestic firms, institutions, and infrastructure. The generalized two-stages least squares (G2SLS) random effect with instrumental variables regression is used with panel data. Findings: Firstly, foreign direct investment has a positive impact on the development of the 63 provinces in Vietnam. Secondly, among the six components, the four most important ones are infrastructure, the level of openness, human capital, and the absorptive capacity of domestic firms. Moreover, the article finds that foreign direct investment can bring negative impacts to provinces with a low level of trade openness. Implications & Recommendations: The government should focus on infrastructure, trading policy, human capital and capability of domestic firms. Contribution & Value Added: There is a lack of connection between absorptive capacity at the firm level and the macro level. Therefore, this article attempts to create this connection by constructing absorptive capacity at the firm level as a component of absorptive capacity at the provincial level. © 2020, Cracow University of Economics.

FDI spill-overs, absorptive capacity and domestic firms' technical efficiency in Vietnamese wearing apparel industry

This study empirically examines relationship between FDI spill-overs and technical efficiency of domestic firms and role of the absorptive capacity of domestic firms. Data on Vietnamese Annual Enterprises Survey are exploited to build a firm-level panel data on the Vietnamese wearing apparel industry from 2009 to 2013. By applying stochastic production frontier model, this paper shows that there are positive vertical spill-over effects but no horizontal effects. Moreover, this study finds the negative impact of the absorptive capacity of domestic firms on benefits reaped from FDI externalities

Land Use Based Flood Hazard Analysis for the Mekong Delta

Das Mekong-Delta nimmt für die Republik Vietnam einen sehr hohen Stellenwert in Bezug auf Natur, Wirtschaft, Politik, Menschen, Landwirtschaft, Fischerei, Geopolitik und vielen anderen Bereichen ein. Der sogenannte Dreifachreis (auch Herbst-Winter-Ernte oder Third Crop genannt) wurde in den letzten Jahren für das Mekong-Delta in den stark überfluteten Gebiete durch umschlossene Kompartimenten wie Halbdeichstrukturen (zum Schutz der Reisfelder vor Hochwasser (von Juli bis Mitte August) sowie Volldeichmessungen (zum vollständigen Schutz der Reisfelder während der Hochwassersaison) schnell ausgebaut. Der Reisanbau hat daher Auswirkungen auf die Hochwassersituation in den flußabwärts gelegenen Gebieten. Diese Studie zielt darauf ab, die Auswirkungen von Deichmessungen auf Hochwasser in den Mekong-Flüssen zu analysieren, indem das 1D-Hydraulikmodell MIKE11 sowie Fernerkundungsprodukte (MODIS-Satellit) verwendet werden. Um diese Einflüsse umfassend zu erforschen, wurde mit dem Hydraulikmodell MIKE11 die Auswirkungen von mehreren Volldeichkompartimenten auf das Hochwasser entlang der Hauptflüsse basierend auf einem Geographical Impact Factor (GIF) analysiert. Der Autor fand heraus, daß verschiedene geografische Kompartimente unterschiedliche Einflüsse auf das Hochwasserniveau entlang des Mekong haben. Fernerkundungsprodukte wurden eingesetzt, um die Veränderung der Landnutzungsgebiete im Mekong-Delta von 2000 bis 2017 zu analysieren. Außerdem wurde von MODIS Satellitenprodukte eine komplette Datenbank von Hochwasserverteilungskarten (476 Karten) im Mekong-Delta während der Hochwassersaison 2000 bis 2017 interpretiert. Darüber hinaus wurden die Satellitenprodukte einschließlich Landnutzung und Hochwasserkarten in MD zu weiteren Untersuchungen des Mekong Delta für die Öffentlichkeit online zur Verfügung gestellt. Die Simulation funktioniert für ein großes und komplexes Flussnetz, da das Mekong-System viele Anstrengungen und Erfahrungen der Ingenieure erfordert, die nicht leicht zu bewältigen sind. Daher wurde eine einfache Methode zur Interpretation des Hochwasserstandes entlang der Mekong Flüsse entwickelt, um Ingenieuren ein schnelles Werkzeug zur Bewertung der Auswirkungen von Deichkonstruktionen für Landnutzungszwecke auf Hochwasserregime zur Verfügung zu stellen. Im Bereich Hydraulik wurde ebenfalls eine Empfehlung zum Reisanbau in den Gebieten vom Mekong-Delta abgegeben, welche den Anwendern die Möglichkeit bieten soll, die Ausrichtung der landwirtschaftlichen Entwicklung gegenüber dem Hochwassermanagement zu steuern

On the Interference Alignment Designs for Secure Multiuser MIMO Systems

In this paper, we propose two secure multiuser multiple-input multiple-output transmission approaches based on interference alignment (IA) in the presence of an eavesdropper. To deal with the information leakage to the eavesdropper as well as the interference signals from undesired transmitters (Txs) at desired receivers (Rxs), our approaches aim to design the transmit precoding and receive subspace matrices to minimize both the total inter-main-link interference and the wiretapped signals (WSs). The first proposed IA scheme focuses on aligning the WSs into proper subspaces while the second one imposes a new structure on the precoding matrices to force the WSs to zero. When the channel state information is perfectly known at all Txs, in each proposed IA scheme, the precoding matrices at Txs and the receive subspaces at Rxs or the eavesdropper are alternatively selected to minimize the cost function of an convex optimization problem for every iteration. We provide the feasible conditions and the proofs of convergence for both IA approaches. The simulation results indicate that our two IA approaches outperform the conventional IA algorithm in terms of average secrecy sum rate.Comment: Updated version, updated author list, accepted to be appear in IEICE Transaction

The Factors of Consumer Intension of Using Mobile Payment in Vietnam

Purpose: Within the context of emerging mobile technologies, Mobile payment or M-payment has been introduced as the new trend for payment methods bringing more value and convenience to consumers. However, the development of M-payment services is still quite timid in some Southeast Asia countries including Vietnam. This is also the reason and motivation for the author to do this research.   Theoretical framework: The goal of this study is to spot some factors that affect the use behavior (UB) of M-payment consumers in five major metropolises that were most influential on the economy in Vietnam.   Design/methodology/approach: A quantitative questionnaire was used to measure the responses of participants and Partial Least Squares (PLS) method was employed to analyze the collection data as well as test all hypotheses.   Findings: The results indicated that SI has been the important factor leading to the BI to use M-payment followed by SV and SC issues and BI also had a strong influence on the UB of consumers. Since M-payment is still in the infancy stage and is one of the most exciting mobile applications for the next few years in Vietnam, the identification of important factors concerning M-payments.   Research, Practical & Social Implications: To investigate the factors affecting UB of Vietnamese M-payment consumers, the researcher proposed a research model which analyzes the impact of various variables extracted from system quality (ST), service quality (SV), security (SC), social influence (SI) on behavioral intention (BI) to use and BI on M-payment UB.   Originality/value: This study will assist merchants and software developers to design and improve the systems and services to ensure the full acceptance and continuous use of the systems. Finally, a set of suggestions for the subsequent research works also was listed at the end of this study

Tax holidays and profit-repatriation rates for FDI firms: the case of the Czech Republic

The Czech Republic has been a promising destination for foreign investors due to its locational advantages and tax-incentive policy. However, the profit-repatriation rate in the country is extremely high, which results in less capital being available for development. This paper studies the differences in profit-repatriation rates among FDI (foreign direct investment) firms in the Czech Republic after the appearance of tax-holiday incentives from 2008 to 2019. The precondition is to find the determinants of the repatriation rate of FDI firms, and the results show that the profit repatriation rate of FDI firms is positively affected by firm size and the liquidity of firms and negatively affected by investment opportunities and leverage. The paper divides FDI firms into several groups and examines the differences in repatriation rates between them before revealing the determinants of these differences. Firstly, there is no difference in profit repatriation between FDI firms with tax incentives and those without tax incentives. Next, we divide the FDI firms with tax incentives into two groups: those who still enjoy the tax incentives and those who no longer enjoy the tax incentives. The FDI firms with tax incentives that are in the tax-incentive period repatriate less than FDI firms with tax incentives that are not in the tax period any longer. The difference stems from the endowment effect, and three determinants that can reduce the repatriation rate of FDI firms that are no longer in the tax period are investment opportunities, leverage, and firm size.Technology Agency of the Czech Republic, TACR, (TL03000319); Univerzita Tomáše Bati ve Zlíně, (RO/2022/04)Technology Agency of the Czech Republic [TL03000319]; Tomas Bata University in Zlin [RO/2022/04
