In this blog post, we examine the specific mechanisms through which the structure of clusters—which serve as a key driver of regional development—and the quality of social capital determine innovation capacity.
As the shift toward innovation-driven growth is being pursued, changes have emerged in development models aimed at strengthening competitiveness at the regional level. Key concepts of the innovation-driven regional development model include clusters, regional innovation systems, and social capital.
A cluster refers to a group of geographically adjacent and interconnected firms, as well as firms associated with a specific sector, that are linked based on similarities or complementarities. To assess a cluster’s competitiveness, one must sequentially examine the network structure formed by its interconnected components. Specifically, one must first consider the characteristics of the forward and backward value-added networks of firms or industries, then identify service institutions that provide specialized functions, technologies, and information, and finally determine the role of the government or regulatory agencies. The California Wine Cluster in the United States, often cited as a successful example, was formed in a traditional grape-growing region. Grape cultivation is strongly linked to the region’s agricultural cluster, while winemaking is closely connected to the food and tourism clusters. It also maintains close ties with a local university offering a wine studies program, the local government, and special committees of the state legislature.
A regional innovation system consists of a superstructure—comprising the region’s institutions, culture, norms, and atmosphere—a physical infrastructure—such as transportation and communication networks—and a social infrastructure—including universities, research institutes, businesses, and local governments. It refers to a network system between the superstructure and infrastructure that produces new technologies and knowledge and commercializes them. A regional innovation system must develop with the social infrastructure, composed of innovation actors, closely linked to the superstructure. Furthermore, the physical infrastructure must not only attract innovation actors but also enhance access to their innovative outputs. The Sista Science Park in Sweden is often cited as a prime example; its characteristics can be summarized as active industry-academia-research collaboration, a cooperative framework between large corporations and small and medium-sized enterprises (SMEs), local government investment in infrastructure such as roads, and vigorous joint research among competing firms.
Social capital refers to coordination, cooperation, reciprocal norms, and social trust among participants in a community—such as a nation, region, or individual group—and denotes the conditions that enable participants to work together efficiently to pursue shared goals. Since the 1980s, interest in social capital has stemmed from the recognition that the achievement of a community’s goals depends on the nature and quality of social capital. A prime example often cited is the Nakama Community in Ota Ward, Japan, which is composed primarily of small businesses. The term “Nakama Community” refers to a group characterized by relationships akin to business partners or close acquaintances. Small businesses in this region, each with 10 or fewer employees, form a community intertwined like a web based on the principles of trust, cooperation, and competition. Through this, the businesses are enhancing their specialized capabilities and achieving results comparable to those of large corporations.
The concepts of clusters, regional innovation systems, and social capital all emphasize the importance of networks for innovation-driven regional development. In clusters and regional innovation systems, a network refers to the interconnection system among components itself, serving as a driving force for enhancing regional value-added and innovation. The nature of a social capital network varies depending on the degree of reciprocity in its components—coordination, cooperation, trust, and norms—and while the network itself is important, the qualitative level of these components is even more critical. In this context, social capital acts as a catalyst that activates relationships among components within various types of networks. In other words, when high-quality social capital is formed within the networks of clusters and regional innovation systems, the number of participants increases and the frequency of interaction also rises. Consequently, clusters and regional innovation systems grow within a strong sense of solidarity, creating a collective synergy that enables innovation-driven regional development.
