Nemzetgazdasági versenyképesség: elmélet, mérés, esettanulmányok = Competitiveness of National Economies: Theory, Measurement, Case Studies

Műhelytanulmányunk a nemzeti versenyképesség vállaltokon túli dimenziójával kíván foglalkozni. A felgyorsult globalizáció korának világgazdasági környezetében, ahol a nemzetköziesedett nagyvállalatok rendelkeznek az erőforrások és a közvetlen beruházások jelentős része felett és az egyes regionális piacok folyamatai gyorsan áttevődnek más régiókra, a gazdaságpolitika és tágabb értelemben az állam mozgástere és feladata megváltozott. Ez az országokra nézve azt jelenti, hogy a stabil üzleti környezet megteremtésével és az emberi erőforrás illetve a technológiai infrastruktúra, mint háttérerőforrások fejlesztésével képesek hosszútávon megalapozni a gazdasági növekedést és felzárkózást, függetlenül attól, hogy az európai gazdasági integrációs környezetben valósítják-e meg mindezt. _____ The working paper examines the dimensions of competitiveness over the corporate level. The regional positions are changing quickly and the room for manoeuvre of the economic policy in national level is narrowed for attraction of business activities in the era of quickened globalisation. The countries compete for direct investments with the level of stability in business environment, the quality of human resource, the development of technological infrastructure. The development of background factors determines the economic growth.

Borrowing services from nature. Methodologies to evaluate ecosystem services focusing on Hungarian case studies.

In modern societies, humans are largely managing the world's natu­ral resources as if they were limitless. ln fact, even the so-called renewable resources require time tor renewal once they have been used. This kind of human attitude puts pressure on Earth's ecosystems at an unprecedented scale. In order to reverse the recent trend, policies shall tackle the roots of the problems and the drivers behind them must be addressed in order to reduce the pressure on ecosystems, including the overuse of natural resources and ecological space. This publication aims to show good examples tor evaluating natural values and tor showing possible environmental and social impacts of various policies. Considering carefully the examples presented in this publication could play fundamental role in proper decision making that considers environmental and overall sustainability aspects.

Zoocoenological state of microhabitats and its seasonal dynamics in an aquatic macroinvertebrate assembly (Hydrobiological case studies on lake Balaton, No. 1.)

In the years 2002, 2003 and 2004 we collected samples of macroinvertebrates on a total of 36 occasions in Badacsony bay, in areas of open water (in the years 2003 and 2004 reed-grassy) as well as populated by reed (Phragmites australis) and cattail (Typha angustifolia). Samples were taken using a stiff hand net. The sampling site includes three microhabitats differentiated only by the aquatic plants inhabiting these areas. Our data was gathered from processing 208 individual samples. The quantity of macroinvertebrates is represented by biovolume value based on volume estimates. We can identify taxa in abundant numbers found in all water types and ooze; as well as groups associated with individual microhabitats with various aquatic plants. We can observe a notable difference between the years in the volume of invertebrate macrofauna caused by the drop of water level, and the multiplication of submerged macrophytes. There are smaller differences between the samples taken in reeds and cattail stands. In the second half of 2003 – which was a year of drought – the Najas marina appeared in open waters and allowed to support larger quantities of macroinvertebrates. In 2004 with higher water levels, the Potamogeton perfoliatus occurring in the same area has had an even more significant effect. This type of reed-grass may support the most macroinvertebrates during the summer. From the aspect of diversity relations we may suspect different characteristics. The reeds sampling site proved to be the richest, while the cattail microhabitat is close behind, open water (with submerged macrophytes) is the least diverse microhabitat.
