摘要：This paper investigates the determinants of firm's green investment strategies in equipment for pollution control. It
uses micro-data from a large survey of Italian manufacturing firms from 2001 to 2006. In particular, we test whether
the length of the firm-bank relationship affects the firm's probability of investing in environmentally friendly
equipment. Our findings show that a longer relationship with the main bank fosters firms' involvement in green
investment strategies in order to reduce their environmental impact. Conversely, the presence of a multiple credit
relationship could concretely hinder a firm's investments towards environmental innovations.
