This research examines the evolution of the study on triple helix (TH) approaches to the investigation of regional innovation systems (RISs). Prior studies on TH‐based RISs have focused largely on complex interactions among innovation creating actors (i.e., university, industry, and government) and non‐market institutions in various regional contexts. Although there are a growing number of TH‐based RIS studies, they often ignore the evolutionary aspect of the RIS studies and implications for sustainability. Thus, herein we conduct a wide range of systematic literature review on the TH research in the RIS literature published from 1990 to 2017. The study identifies that the TH literature evolves into various N‐helix models in particular, gravitating toward stakeholders, internationalization, specialization and ecological conservation, which offers various implications for sustainability in the regional development context. In the ages of globalization, digitalization, and socio‐ecology, this study offers a comprehensive view on the TH research for sustainable development and suggests useful future research directions that academics and policymakers can benefit from.

区域创新体系的N螺旋演化：对可持续性的影响

这项研究考察了三重螺旋（TH）方法研究区域创新系统（RISs）的研究进展。基于TH的RIS的先前研究主要集中于在各种区域环境下创新创造者（即大学，行业和政府）与非市场机构之间的复杂相互作用。尽管基于TH的RIS研究的数量在不断增长，但它们经常忽略RIS研究的进化方面及其对可持续性的影响。因此，在这里，我们对1990年至2017年出版的RIS文献中的TH研究进行了广泛的系统文献综述。该研究确定TH文献尤其演变为各种N螺旋模型，倾向于利益相关者，国际化，专业化。和生态保护，这对区域发展背景下的可持续发展具有各种影响。在全球化，数字化和社会生态学的时代，本研究提供了有关TH可持续发展研究的全面观点，并提出了有益的未来研究方向，学者和政策制定者可以从中受益。
