Cities host diverse people and their mixing is the engine of prosperity. In turn, segregation and inequalities are common features of most cities and locations that enable the meeting of people with different socio-economic status are key for urban inclusion. In this study, we adopt the concept of economic complexity to quantify the sophistication...

Millions commute to work every day in cities and interact with colleagues, customers, providers, friends, and strangers. Commuting facilitates the mixing of people from distant and diverse neighborhoods, but whether this has an imprint on social inclusion or instead, connections remain assortative is less explored. In this paper, we aim to better u...

It is generally acknowledged that in order to have access to locally accumulated industrial knowledge, firms have to collaborate and take part in cluster knowledge networks. This study argues that the inherited capabilities of spinoff enable them to cooperate and exchange knowledge more easily and to gain more from positive knowledge externalities...

Relatedness has become a key concept for studying the diversification of firms, regions and countries. However, studies tend to treat relatedness as being time‐invariant or, alternatively, consider its evolution as exogenously given. This study argues that relatedness is inherently dynamic and endogenous to technological and economic developments....

In collaboration-based creative industries, such as film production, creators in the network core enjoy prestige and legitimacy that are key for creative success. However, core creators are challenged to maintain diverse access to new ideas or alternative views that often emerge from the network periphery. In this paper, we demonstrate that creator...

Social connections that span across diverse urban neighborhoods can support prosperity by mobilizing social capital. However, there is limited evidence on the spatial structure of individual social capital inside cities. This paper demonstrates that social capital measured by online social connections is spatially more concentrated for residents of...

ABSTRACT In this study we investigate the creation and persistence of interfirm ties in a large-scale business transaction network. Transaction ties, firms buying or selling products or services can be the outcome of pure business motivations, but the social connections of owners or the geographical location of companies may also influence their de...

Social connections that span across diverse urban neighborhoods can help individual prosperity by mobilizing social capital in cities. Yet, how the detailed spatial structure of social capital varies in lower- and higher-income urban neighborhoods is less understood. This paper demonstrates that the social capital measured on social networks is spa...

This paper explores the spatial patterns and underlying determinants of repeated inventor collaboration across European NUTS 3 regions. It is found that only a small fraction of co-inventor linkages across regions are repeated, while community detection reveals that these collaborations are clustered in geographical space more intensively compared...

A fejlesztési pólusok koncepciója a hazai térségekben koncentrálódó tudásintenzív tevékenységek nyújtotta előnyök megerősítését és kiaknázását tűzte ki célul. Kutatás-fejlesztési, gazdasági és infrastrukturális adottságaik alapján tágabb térségüket dinamizálni képes pólusvárosokat és hozzájuk kapcsolódó húzóágazatokat jelöltek ki, így Szegeden a Bi...

Inventor collaborations that span across regions facilitate the combination and diffusion of innovation-related knowledge. While remote partnerships are gaining importance; most R&D cooperations remain embedded in local environments and little is known about how spatial patterns of creation and persistence of ties in large-scale co-inventor network...

Knowledge networks are important to understand learning in industry clusters but surprisingly little is known about what drives the formation, persistence and dissolution of ties. Applying stochastic actor-oriented models on longitudinal relational data from a mature cluster in a medium-tech industry, we show that triadic closure and geographical p...

A gazdasági tevékenységek térbeli sűrűsödéséből származó agglomerációs előnyökhöz nem egyformán férnek hozzá a vállalatok. Különösen a tudástúlcsordulás formájában jelentkező előnyök kihasználásához a technológiai tudás hasonlóságára, közelségére van szükség. Ez a technológiai közelség kedvezően hat a térségek gazdasági növekedésére és az új gazdas...

Kikkel alakítanak ki kapcsolatot a gazdaság szereplői? Milyen jellemzők befolyásolják e kapcsolatok alakulását? Örökké tartanak ezek az együttműködések? A hálózatok dinamikájának vizsgálatával az utóbbi időben többen tettek kísérletet ezeknek a kérdéseknek a megválaszolására. Jelen tanulmánnyal az a célunk, hogy felhívjuk a hazai közgazdászközösség...

Kulcsszavak: tudáshálózat, regionális klaszter, hálózatelemzés, spin-off cégek Hogyan lesznek bizonyos cégek meghatározó sze-replői egy klaszternek? A kérdés megválaszolásához a Kecskeméti nagyvárosi településegyüttes nyomda-iparának és papírtermék gyártásának tudáshálózatát vizsgáltuk meg, a cégszintű kapcsolatok adatai alap-ján. A kiegészítő váll...

A relatively recent development in the field of economic geography, interested in the uneven spatial distribution of economic activities, is the less metaphoric and more formal involvement of network analysis tools in empirical strategies. Furthermore, with the diffusion of innovation systems thinking, and the emerging empirics of evolutionary econ...
