%X R2作为股价同步性的特征变量，与公司面信息紧密相连。随着时代发展，社会变迁不断被赋予新的内涵。学者从不同的视角出发开展研究，推动了股价同步性、资本市场定价与行为金融理论、信息不对称理论、委托代理理论等融合发展，并与经济地理、企业管理、人力资源、大数据等多学科进行交叉，提升了思维的深度和广度。学者们通过对R2形成机制，影响效应的研究和探索，取得了丰硕的成果。本文从R2的定义出发，梳理了R2的形成与发展，并对尚存的争论进行总结和评述，最后结合我国资本市场放开、注册制改革、建设金融强国，推动经济高质量发展等具体背景，对R2研究进行了展望。
R2, as a characteristic variable of stock price synchronicity, is closely related to company information. With the development of the times and social changes, it is constantly endowed with new connotations. Scholars have conducted research from different perspectives, promoting the integration and development of stock price synchronicity, capital market pricing and behavioral finance theory, information asymmetry theory, principal-agent theory, and other interdisciplinary fields such as economic geography, accounting, enterprise management, human resources, and big data, enhancing the depth and breadth of thinking. Scholars have achieved fruitful results by studying and exploring the formation mechanism and impact effects of R2. Starting from the definition of R2, this article sorts out its formation and development, summarizes and comments on the remaining debates, and finally puts forward prospects for R2 research from the specific background of China’s capital market liberalization, registration system reform, building a strong financial country, and promoting high-quality economic development.
