Collective Learning and Relational Capital in Local Innovation Processes

Innovative capacity of firms has traditionally been explained through intra-firm characteristics. In the more recent literature, much emphasis has been put on determinants that are external to the firm. These external factors, called knowledge spillovers, refer to the positive externalities that firms receive in terms of knowledge from the environment in which they operate. Geographers and industrial economists underline the importance of knowledge spillovers. Relational capital is defined as all relationships – market relationships, power relationships and cooperation – established between firms, institutions and people, which stem from a strong sense of belonging and a highly developed capacity of cooperation typical of culturally similar people and institutions. The main aims of the paper are twofold. The first is to underline the major conceptual differences between industrial and regional economists. The second is to provide a quantitative empirical approach, using econometric techniques, to verify the existence and importance of relational capital on the innovation activity of firms. Proxies are found to represent the channels through which local knowledge develops at the local level and therefore indirectly of relational capital. The different regional, sectoral and firm characteristics are also analysed to understand whether they influence the role relational capital has on innovation. It is indeed reasonable to expect that relational capital will play a different role in different regional, sectoral and firm’s contexts.
