On the afternoon of November 24th, Professor Zhang Xun from the Department of Financial Statistics at Beijing Normal University's School of Statistics, upon our institution's invitation, delivered a lecture titled "Development of Digital Finance and the Construction of a National Unified Large Market" in the Second Conference Room on the eleventh floor of the South Comprehensive Building in Jiaoqiao Garden. The lecture was presided over by Vice Dean Wang Shoukun, with the attendance of some faculty and students from our institution.

Professor Zhang Xun's presentation delved into the mechanisms of digital finance, covering five key areas: the expansion of the domestic market, optimization of the business environment, reduction of market transaction costs, technological innovation and industrial structure upgrading, and the acceleration of cultivating new advantages in international competitive cooperation. He approached the topic from both theoretical and empirical perspectives, providing detailed explanations of the crucial roles of digital finance in various domains. To identify the net effects of digital finance development more comprehensively, Professor Zhang Xun used commodity-level price differentials as a representation of market segmentation and constructed a massive database with millions of observations. This systematic research approach allowed for a more comprehensive understanding of the profound impacts of digital finance on the economy and the market.

After the presentation, the faculty and students who participated in the lecture gained many insightful inspirations. They engaged in in-depth discussions and interactions with Professor Zhang Xun, covering topics such as the perspective on entering the unified large market, measurement issues of commodity price differentials, the scope of application of digital inclusive finance, and misconceptions and data representativeness issues in the application of the digital inclusive finance index.

This lecture provided a rare learning opportunity for the entire faculty and students, allowing them to gain a deeper understanding of the cutting-edge knowledge and development trends in the field of digital finance. Vice Dean Wang Shoukun expressed sincere thanks to Professor Zhang Xun for his brilliant presentation.
