Megjegyzések:	aBusiness groups have been described as improving the value of the affiliated firms they control, which is often beyond the capability of standalone firms. The purpose of the current study is to analyze the financial performance of affiliates of diversified Pakistani business groups relative to standalone firms. The current study employs data from 284 Pakistani listed non-financial firms from 2008?2015. In order to test the hypotheses, two dependent variables are used, namely, accounting (Return on Assets (ROA)) and stock market (Tobin's Q) measures of performance. Specifically, this study probes and compares the performance measures of group member and standalone firms. The findings of the study suggest that business group memberships have statistically significant effects on accounting and stock market measures of firm performance. In addition, size and sales growth have an increasing effect on the performance of firms. We believe that business groups in Pakistan are efficient economic actors and can be considered responses to high transaction costs and market failures.

Cím:	The Significance of Forests and Algae in CO2 Balance : a Hungarian Case Study / Attila Bai, József Popp, Károly Pető, Irén Szőke, Mónika Harangi-Rákos, Zoltán Gabnai
Dátum:	2017
ISSN:	2071-1050
Megjegyzések:	This study presents the sequestration and emissions of forests and algae related to CO2 while providing a comparison to other biomass sources (arable crops, short rotation coppices). The goal of the paper is to analyze the impact of the current CO2 balance of forests and the future prospects for algae. Our calculations are based on data, not only from the literature but, in the case of algae, from our own previous experimental work. It was concluded that the CO2 sequestration and natural gas saving of forests is typically 3.78 times higher than the emissions resulting from the production technology and from the burning process. The economic and environmental protection-related efficiency operate in opposite directions. The CO2 sequestration ability of algae can primarily be utilized when connected to power plants. The optimal solution could be algae production integrated with biogas power plants, since plant sizes are smaller and algae may play a role, not only in the elimination of CO2 emissions and the utilization of heat but also in wastewater purification.

Cím:	Role of domestic financial reforms and internationalization of non-financial transnational firms : evidence from the Chinese market / Muhammad Saad Baloch, Abubakr Saeed, Ishtiaq Ahmed, Judit Oláh, József Popp, Domicián Máté
Dátum:	2018
ISSN:	2071-1050
Megjegyzések:	The successful internationalization process of Chinese firms which enhances the sustainability of the Chinese economy receives massive research attention. Studies emphasize that firm's motives and institutional voids play a pivotal role in getting benefits from the internationalization process, but the factors that initiated this process have been overlooked. The objective of this study is to explore the impact of those institutional factors which initiated the internationalization process. This study reveals that institutional factors of cross listing and increased financial availability induced the internationalization process of Chinese firms. Using the financial data of non-financial firms for the period of 2005-2015, we demonstrate that the domestic financial reforms initiated the internationalization process that helps Chinese economies to achieve sustainable economic development. The study also finds that state-ownership helped firms to gain more from increased financial availability than the stand-alone firms. The study concludes that the open business environment helped firms to survive and sustain the international pressure successfully and maintain their sustainable performance.

Cím:	Constraining Factors in Hungarian Carp Farming : an Econometric Perspective / Gyalog Gergő, Oláh Judit, Békefi Emese, Lukácsik Mónika, Popp József
Dátum:	2017
ISSN:	2071-1050
Megjegyzések:	Although carp farming had a key role in the Blue Revolution at a global level, European carp aquaculture has stagnated over the past 25 years without achieving any productivity gains. The objective of this study was to identify the factors and mechanisms constraining production and productivity growth in pond-based carp farming in Hungary, as the country is a good representative of the EU pond-based farming sector. By using data from 44 carp farms, different specifications of the Cobb-Douglas production function were parameterized to investigate the determinants of yields and to assess the extent of economies of scale. Descriptive statistics show that large differences exist in productivity between individual farms, meaning that it is hard to implement technical standards and to ensure repeatability in extensive carp farming technology. Econometric analysis demonstrates that economies of scale do not prevail in pond-based farming in Hungary, so a concentration of farms would not stimulate a growth in carp farming. This may explain the stagnation of carp aquaculture, as the only European aquaculture segments which can grow are those that can exploit economies of scale. Further analysis demonstrates that labour is an important factor of production, and a decreasing workforce may constrain the intensification process of production. On the other hand, mechanisation did not prove to be a significant contributing factor to yields, indicating that large investment in equipment has a limited role in carp farming.

Cím:	Building Coalitions for a Diversified and Sustainable Tourism : two Case Studies from Hungary / Lakner Zoltán, Kiss Anna, Merlet Ivan, Oláh Judit, Máté Domicián, Grabara Janusz, Popp József
Dátum:	2018
ISSN:	2071-1050
Megjegyzések:	The development of the tourism sector has been a question of strategic importance for Hungary, a small, open economy with limited natural resources. At the same time, these efforts often generate considerable environmental conflicts, decreasing the sustainability of the environment. To understand the potential methods of sustainable tourism development, and to develop the optimal policy, it is essential to clarify the actors, their systems of interest and the potential ways of forging coalitions between them. The article presents an analysis of two case studies of rural tourism development: the "softening" of tourism at the most important touristic attraction in Hungary, Lake Balaton; and the conflicts arising from wine tourism development. Based on institutional economics, principle?agent theory and strategic management, and applying the MACTOR method, the authors identify the key actors, present the network of their mutual influences and goals, determine the most important conflicts and highlight the potential coalitions between them from the point of view of sustainable rural tourism development, as well as ways to further develop the regulatory environment. Based on this analysis, the article proves: (1) the importance of the modernization and re-organization of the public administration structure, focusing on optimal utilization of resources, as opposed to attaching to traditions; (2) the importance of forming clusters of different partners; (3) the strengthening of the knowledge base of decisions concerning sustainable tourism management; and (4) increasing conscious planning, based on the inclusion of different interest groups and long-term prognoses in local decision making, minimises the environmental burden of tourism.

Cím:	The Role and Impact of Industry 4.0 and the Internet of Things on the Business Strategy of the Value Chain - The Case of Hungary / Judit Nagy, Judit Oláh, Edina Erdei, Domicián Máté, József Popp
Dátum:	2018
ISSN:	2071-1050
Megjegyzések:	In the era of industrial digitalization, companies are increasingly investing in tools and solutions that allow their processes, machines, employees, and even the products themselves, to be integrated into a single integrated network for data collection, data analysis, the evaluation of company development, and performance improvement. To study the impact of Industry 4.0 on the company we used Porter's (1985) value chain model, which is particularly useful when paying particular attention to corporate areas which have a primary role in customer value creation. Since the primary impact of Industry 4.0 is perceived in value-creating processes, and has so far had the greatest transformative effect in this area, the model can be considered to be appropriate. The objective of our research is to discover how companies operating in Hungary interpret the phenomenon of Industry 4.0, what Internet of Things (IoT) tools they use to support their processes, and what critical issues they face during adaptation. We applied a dual methodology in our investigation: We sent an online questionnaire to manufacturing and logistical service companies to investigate the IoT tools they use, and the problems they face, and received 43 answers we could evaluate. We also conducted four expert interviews with manufacturing firms to get deeper insights into the application, critical issues and development phases of IoT tools. During our research, we found that the spread of real-time data across companies?given the availability of appropriate analytical tools and methods?can have a significant impact on the entire company. In the case of CPS (Cyber Physical System), CPPS and Big Data Technologies, companies using them have been evaluated as having a higher level of logistic service, more efficient processes with their partners, improved cooperation between certain logistic functions, and higher market and financial performance and competitiveness. Applying more efficient production processes, and achieving better productivity and economies of scale, might also result in increased economic sustainability. Furthermore, we have found that companies have started on the path to digital evolution, and investments of this type have already begun.

Cím:	Analysis and comparison of economic and financial risk sources in SMEs of the Visegrad Group and Serbia / Judit Oláh, Sándor Kovács, Zuzana Virglerova, Zoltán Lakner, Maria Kovacova, József Popp
Dátum:	2019

Megjegyzések:	Risk management is one of the most important internal process, not only in large companies but also in small and medium-sized enterprises (SMEs). To identify the source of risk can be crucial in all companies. The primary objective of this study is to analyze and compare the economic and financial risk sources in SMEs of the V4 (Visegrad Group: Czech Republic, Hungary, Poland and Slovakia) and Serbia, in the context of the business environment of the countries analyzed. To achieve this goal, a questionnaire-based survey was carried out involving 2110 SMEs from Hungary, Poland, Slovakia, the Czech Republic, and Serbia. The questionnaire included questions about the importance of risks and the concept of risk management in the company. To test the formulated hypotheses, the following statistical tools were used: contingency tables, a Z-value, and a general non-hierarchical log-linear model with three categorical variables and a continuous covariate. Finally, the differences among V4 countries and Serbia were identified. Serbia is more vulnerable to the financial risk sources studied than the V4 countries. The result of the research shows that insufficient profit is more hazardous compared to the other risk sources and all countries are more vulnerable in in this issue. The article concludes with a discussion and a comparison with previous international researches.

Cím:	Achieving Sustainable E-Commerce in Environmental, Social and Economic Dimensions by Taking Possible Trade-Offs / Oláh Judit, Kitukutha Nicodemus, Haddad Hossam, Pakurár Miklós, Máté Domicián, Popp József
Dátum:	2019
ISSN:	2071-1050
Megjegyzések:	The Internet revolution has led to the advancement of online business all over the world. The environmental, social, and economic aspects are significant to the e-commerce sector, on both the retailer and consumer sides. It cannot be over-emphasized how important the sustainability of e-commerce in all three dimensions is. E-commerce will allow consumers to shop online easily, at any hour of the day, using secure payment systems; furthermore, trust in retailers' websites is of paramount importance to consumers. This calls our attention to the gap in previous studies, and consequently, the purpose of this study is to fill the gap, to ensure sustainable e-commerce in three dimensions; environmental, social, and economic. The question and aim under investigation are: How to integrate three dimensions into e-commerce to ensure that sustainability is achieved now and for future generations, while thriving as an industry? Collaboration is required, and all stakeholders in the virtual market must take appropriate responsibility. The methodology adopted is a review of previous studies done on each individual dimension of sustainability, since no joint studies have been carried out and integrated into the same literature framework. Furthermore, a case study involving companies in Kenya and Jordan is used in order to collect empirical data. The findings of the study show that: First, integration is essential for the sustainability of e-commerce in its three dimensions; second, trade-offs must be taken in the various dimensions in order for companies to realize sustainable e-commerce. This will go in hand with the realization of the maximum benefits of integrating the three dimensions in e-commerce to make it more sustainable. In conclusion, by applying these aspects of sustainability in e-commerce, it is clear that everyone wins. This is achieved by improving and safeguarding the quality of life by protecting the environment, preserving natural resources, and maintaining and sustaining the economy. The implications of the study are that, in order to make e-commerce more sustainable, to make decisions and take action, social/environmental/economic aspects must be considered as a fundamental element, and must be treated as a group and not separately as in previous studies. In this way, we can realize greater benefits, not only in online business sustainability, but also in policy-making and environmental protection, while companies will create economic value as well as avoiding labor unrest.

Megjegyzések:

This research focuses on the role of trust and the impact of its level on the revenue, earnings before tax and the degree of flexibility of logistics service providers (LSPs). More specifically, the role of the executive manager is examined in relation to the impact of business relationships (trust levels) within and between organizations. In addition, the analysis covers the development of revenue, earnings before tax and degree of flexibility of logistics service providers in the context of the role of the head manager. The data were collected from 51 logistics service providers in Hungary. The results show that the level of trust established in the organization (with the employees, co-workers etc.) has a positive impact on the earnings before tax. Furthermore, this paper confirms that the trust executive managers establish around them is an important performance factor which even consumers perceive and that it has major significance in terms of degree of flexibility. This research further increases our understanding of the role and importance of trust as a strategic success factor for LSPs

Cím:	The Impact of Supply Chain Integration and Internal Control on Financial Performance in the Jordanian Banking Sector / Miklós Pakurár, Hossam Haddad, János Nagy, József Popp, Judit Oláh
Dátum:	2019
ISSN:	2071-1050
Megjegyzések:	The aim of this paper is to use a recently developed framework of supply chain integration (SCI) to examine the influence of a set of relationships between SCI and internal control on financial performance in the Jordanian banking sector. SCI consists of external integration and internal integration. External integration includes customer integration and supplier integration. This study utilizes survey data from 249 employees in the Jordanian banking sector and tests the research framework and hypotheses using exploratory factor analysis. The impact of supply chain internal and external integration and internal control significantly affected financial performance. The impact of the examined factors on financial performance is as follows, in decreasing order: internal integration, supplier integration, customer integration, and internal control. This study's contribution to supply chain management is in its integration of SCI and internal control variables to propose a practical framework for the banks to use, and its development of a measurement tool for managers to determine the effects of internal and external integration and internal control on financial performance.

Cím:	Biofuel use : peculiarities and implications / József Popp, Sebastian Kot, Zoltán Lakner, Judit Oláh
Dátum:	2018
ISSN:	2029-7017 2029-7025
Megjegyzések:	Transport biofuels are currently the fastest growing bioenergy sectors even they represent around 3-4% of total road transport fuel and only 6% of total bioenergy consumption today. Low oil prices and poor margins continue to challenge biofuel producers in Europe. Under current market conditions it is unlikely that the 7% cap will be reached in the EU by 2020. Since the past ten years, production of biodiesel from waste and animal fats has taken off, while the commercialization of cellulosic ethanol is lagging behind compared to former targets. Co-products are supposed to be credited with the area of cropland required to produce the amount of feed they substitute. If co-products are taken into account, the net use of land and feedstocks declines. Most existing biofuel regulations significantly undervalue the contribution of co-products when assessing the net land use and GHG impacts of biofuel production. Long-term transport shares are the most challenging to project because the range of possible vehicle technologies and fuel types in the future is very broad and future oil prices are uncertain. It is concluded that the rise in the use of biofuels has slowed down and sustainability criteria have been established regarding the use of land and the mitigation of environmental impacts caused by biofuel production.

The paper highlights the principal researchers in this field together with their authorship and citation networks on the basis of 714 articles written between 2006 and 2015. Results suggest that the majority of the articles were written by a small number of researchers, indicating that groups and central authors play an important role in scientific advances. It also turns out that the number of articles and the central role played in the network are not related, contrary to expectations. Results also suggest that groups cite themselves more often than average, thereby boosting the scientific advancement of their own members.
