How much do cluster institutions drive a firm’s green innovation? A multi-level analysis
研究了宏观正式制度与集群层面非正式制度对企业绿色产品创新的互补作用，基于三个国家三个鞋业集群中177家企业的混合方法分析，发现集群效应正向影响绿色创新，且国家制度正向调节集群非正式制度的作用。
This research explores the complementary role of formal institutions at the macro-level and informal ones at the cluster level on a firm’s green product innovation. Using mixed methods in a sample of 177 firms dedicated to the footwear industry, belonging to three clusters in three different countries, findings suggest that: (1) the cluster effect positively influences a firm’s green product innovation; and (2) informal cluster-level institutions’ effect on green product innovation is jointly and positively moderated by national institutions. Green innovation in clusters requires coupling different multi-scalar institutional systems effectively.
