Index of Regional Innovation and Entrepreneurship in China (IRIEC)

Index of Regional Innovation and Entrepreneurship in China (IRIEC) is constructed by the Center for Enterprise Research (CER) of Peking University as an objective, real-time and multi-dimensional index to reflect the temporal and spatial distribution of innovation and entrepreneurship activities, utilizing administrative business enterprise registration database in China from 1990 to 2020 in combination with big data from other sources. We mainly focus on three core elements, i.e., entrepreneurship, capital, and technology, using the number of new enterprises, outside direct investment, venture capital investment, number of patents granted, and trademark registration.

中国区域创新创业指数（Index of Regional Innovation and Entrepreneurship in China, IRIEC）由北京大学企业研究中心（Center for Enterprise Research, CER）编制完成，是一套客观、实时且多维度的指数体系，用于反映创新创业活动的时空分布特征。该指数整合利用1990年至2020年中国工商企业登记数据库，并结合其他多源大数据构建而成。研究团队主要聚焦创业、资本与技术三大核心要素，选取新增企业数量、外部直接投资、风险投资、专利授权量以及商标注册量作为核心测算指标。
