Abstract: The emerging industry innovation network has its complexity and particularity. Taking the hydrogen energy industry in Zhangjiagang as a case, based on the field research and interview data, this paper analyzes the connection form, spatial scale and formation mechanism of the emerging industries innovation network. The main conclusions are: The hydrogen energy industry innovation network spatial form is a combination of central and non-central network. Both formal and informal connection in innovation network are influenced by path dependence, and can transform and promote each other. There are differences in the formation mechanism of innovation network on different scales. on local scale, the main mechanism is geographical and social proximity; on domestic scale, it is cognitive, organizational, institutional and social proximity; while on global scale, it is cognitive, organizational and social proximity. There are two ways to create cross-regional innovation links in China: government-led "top-down" and market-led "bottom-up". There are organizational and institutional proximity between local governments and universities, research institutes, which promotes the establishment of innovation networks.
