The success of a cluster depends on the interplay between intra- and inter-regional collaboration, while empirical research on the mechanisms through which intra- and inter-regional collaborations trigger cluster growth is rarely focused. Based on the local buzz–global pipelines framework and incorporating an evolutionary perspective, we explore how intra- and inter-regional innovation networks can be integrated to drive the growth of emerging industries. We draw on Zhangjiang, China’s most advanced AI industry cluster, using social network analysis and qualitative methods, combining patent data with semi-structured interviews. The results indicate that with the return of multinational corporations and the limitation of Western technology, universities have become the primary source of AI innovation in Zhangjiang. The government has played a pivotal role in propelling the accelerated growth of China’s AI industry, particularly through the backing of pioneering AI private enterprises and the calibration of the potential inefficiencies associated with a state-led model with the dynamism of market forces. The ‘Buzz-and-pipeline’ dynamics in the AI innovation network are shaped by four processes: local networking, market demand, resource integration, and policy synergy. This underscores the intricate interconnections between the national and local scales in AI innovation networks. Full article

Knowledge flow is among the most crucial social processes triggering innovation and regional development. Intercompany knowledge flow among Polish information technology (IT) service small- and medium-sized enterprises (SMEs) is studied in this paper. The main aim is to identify market and technological knowledge flow channels and their spatial scales. Based on information derived from computer-assisted telephone interviews (CATIs), in-depth interviews (IDIs) and data analysis (correspondence analysis and comparative study of spatial structures of knowledge flows), the geographical proximity paradox is tested. It is argued there is a need to move beyond the local buzz–global pipeline dichotomy. Knowledge is acquired at various spatial scales, which enhances the sustainability of the knowledge acquisition process and makes companies, regions and cities more resilient. The multiscalarity of knowledge flows is the most remarkable in the case of private contacts with colleagues from schools or previous workplaces. Spatially diversified study and job experiences of entrepreneurs goes along with return migration. In earlier Central and Eastern European studies, knowledge flow was often defined by the dominance of national (domestic) flow over weak global interactions. Trade relations, especially those occurring on an international scale, represent the most important channel of market and technological knowledge flow for the surveyed companies. The second most important channel is the employment of specialists, which is by far the most frequent and most important on an interregional scale. Due to the small size of surveyed companies, foreign specialists are used least frequently. Instead of using regional business events as a vehicle for knowledge flow, representatives of the IT service sector prefer to attend domestic meetings. In the case of Polish IT service SMEs, the paradox of geographical proximity is better described by the dominance of national over global knowledge flow. Full article

This paper studies the relationships between network capabilities and innovation development in the context of two types of innovation networks: scientific knowledge networks (SKN) and technological knowledge networks (TKN). Focusing on two types of network capabilities, namely acquisition capability and control capability, the paper uses spatial regime models to compare the impacts of multiple factors on different spatial regimes. The main conclusions are the following. First, as regards SKN, the political-administrative hierarchy has shaped the spatial evolution of acquisition capacity, forming a pattern consisting of three dominant cities (Beijing, Shanghai, Nanjing), three subsidiary cities (Guangzhou, Hangzhou, Wuhan), and multiple lesser centers (Tianjin, Chengdu, Xi’an). Moreover, high control capability cities are mainly clustered in the coastal areas, specifically, one monocentric city (Beijing) and two polycentric metropolises (Shanghai, Wuhan). Second, for TKN, cities with high acquisition and control also are mainly found in coastal areas, with Shanghai and Beijing dominating network capabilities. The model’s analysis confirms the positive effect of network capabilities on innovation development, especially in scientific knowledge networks, and the driver for regional innovation development appears to have shifted from global pipeline (globalization) to local buzz (localized talents). This paper concludes with suggestions regarding network capabilities’ potential to reduce regional inequality and achieve sustainable development of regional economies. Full article

An attractive cultural heritage is an important magnet for visitors to many cities nowadays. The present paper aims to trace the constituents of the destination attractiveness of 40 global cities from the perspective of historical-cultural amenities, based on a merger of extensive systematic databases on these cities. The concept of cultural heritage buzz is introduced to highlight: (i) the importance of a varied collection of urban cultural amenities; (ii) the influence of urban cultural magnetism on foreign visitors, residents and artists; and (iii) the appreciation for a large set of local historical-cultural amenities by travelers collected from a systematic big data set (emerging from the global TripAdvisor platform). A multivariate and econometric analysis is undertaken to validate and test the quantitative picture of the above conceptual framework, with a view to assess the significance of historical-cultural assets and socio-cultural diversity in large urban agglomerations in the world as attraction factors for visitors. The results confirm our proposition on the significance of urban cultural heritage as a gravity factor for destination choices in international tourism in relation to a high appreciation for historical-cultural amenities.

Most location-based services are based on a global positioning system (GPS), which only works well in outdoor environments. Compared to outdoor environments, indoor localization has created more buzz in recent years as people spent most of their time indoors working at offices and shopping at malls, etc. Existing solutions mainly rely on inertial sensors (i.e., accelerometer and gyroscope) embedded in mobile devices, which are usually not accurate enough to be useful due to the mobile devices’ random movements while people are walking. In this paper, we propose the use of shoe sensing (i.e., sensors attached to shoes) to achieve 3D indoor positioning. Specifically, a short-time energy-based approach is used to extract the gait pattern. Moreover, in order to improve the accuracy of vertical distance estimation while the person is climbing upstairs, a state classification is designed to distinguish the walking status including plane motion (i.e., normal walking and jogging horizontally), walking upstairs, and walking downstairs. Furthermore, we also provide a mechanism to reduce the vertical distance accumulation error. Experimental results show that we can achieve nearly 100% accuracy when extracting gait patterns from walking/jogging with a low-cost shoe sensor, and can also achieve 3D indoor real-time positioning with high accuracy.
