Stimulating start-ups is conducive to the innovation system and economic development, however, we show how it has additional beneficial effects by the increasing the density of the innovation network. An innovation network is a complex socioeconomic phenomenon, which emerges from the decisions of many heterogeneous agents, that justifies the use of an agent-based model (ABM). We introduce an application of an ABM that is appropriate for simulating network formation among organizations. Agents are placed in the two-dimensional abstract social space where they are moving toward each other to find cooperation partners, following the gravity principle. The attraction is determined by the mass and the distance of agents. These parameters are specified by regression analysis, the result of which shows that the geographical, social, and technological distance has a negative impact on innovation-related cooperation. For the empirical underpinning of the model, we used survey data on the Hungarian high-growth firms’ (known as gazelles ) egocentric network that contains information about innovation-purpose cooperation.}, year = {2023}, eissn = {1432-0592}, pages = {353-377}, orcid-numbers = {Sebestyén, Tamás/0000-0002-5596-0151; Varga, Attila/0000-0001-7252-5648} } @CONFERENCE{MTMT:33615487, title = {Knowledge creation in a nascent biotech innovation system: the case of Pécs city region}, url = {https://m2.mtmt.hu/api/publication/33615487}, author = {Varga-Csajkás, Anna and Manfred, Paier}, booktitle = {61st ERSA Congress}, unique-id = {33615487}, year = {2022}, pages = {432-433} } @article{MTMT:33040890, title = {Hány fecske csinál nyarat?

Ez a tanulmány ezek közül a hálózati viszonosságra és a konformitásra összpontosít.

A kapott eredmények alapján az egyének kapcsolatrendszerének – különösen a konformisták miatt –, valamint a társadalom kezdeti együttműködési intenzitásának jelentős szerepe van abban, hogy milyen mértékű együttműködés jön létre a játék egyensúlyában.
