Environmental Innovations, Local Networks and Internationalization
研究了意大利艾米利亚-罗马涅大区555家企业的环境创新驱动因素，发现与本地供应商和大学合作、培训覆盖及信息技术采用是主要推动力，而集聚经济的作用则取决于产业区特性。
This paper investigates the forces correlated with environmental innovations (EIs) introduced by firms in local production systems (LPS). The role of inter-firm network relationships, agglomeration \neconomies and internationalization strategies is jointly analysed for a sample of 555 firms in the Emilia–Romagna (ER) region (North-East Italy). Cooperating with a certain kind of local actors—i.e. suppliers and \nuniversities—is the most important EI driver for the investigated firms, along with their training coverage and their adoption of information and communication technologies. The role of agglomeration economies is instead less clear-cut. They spur EIs only in the presence of established LPS, with idiosyncratic sector specialization, while conversely they act as EI barriers. Networking effects and agglomeration economies are instead found to strongly promote the adoption of EIs by multinational firms, thus highlighting the importance of local–global interactions. Interesting specifications for these results are found for particular kinds of EIs, in such fields as CO2 abatement and ISO labelling, generally extending the analysis of EI drivers by joining local and international factors. In addition, the role of regulatory sector factors confirms the induced innovation hypothesis and provides a robustness check to our results.
