研究产业集群内社会资本（社会互动、信任、共同愿景和本地机构参与）对企业过程创新和产品创新的影响，基于西班牙巴伦西亚地区220家制造企业的样本分析，发现集群成员身份和社会资本与创新正相关。
This paper aims to introduce some specific insights regarding social networks and the geographical proximity of firms in order to investigate factors involved in the innovation of firms. In particular, this study reviews ideas from the industrial district literature by analyzing the role played by the dimensions of social capital, that is, social interactions, trust, shared vision and involvement of local institutions, in the process and product innovation of firms inside the district. This paper draws on an analysis comparing district members and nonmembers based on a sample of 220 manufacturing firms in the Valencia Region (Spain). Findings suggest a positive association between district affiliation, social capital and involvement of local institutions and innovation that can offer relevant prescriptions for policy makers and individual entrepreneurs.
