Researcher in Economics · CUFE
I am Song Li, a researcher in economics at the Central University of Finance and Economics (CUFE).
My research spans firm economics, regional economics, AI-economy integration, and innovation. I am drawn to questions about how technology reshapes economic geography, how digital forces reorganize production, and — above all — whether those at the bottom truly benefit from these transformations.
This concern is rooted in the ancient wisdom of the I Ching (《周易》). The text speaks of “裒多益寡” — reducing what is excessive to supplement what is insufficient. This is not a naive call for redistribution, but a deep belief in the equilibrium of the Tao. My current working paper, examining how the digital economy promotes regional common prosperity, grows directly from this conviction.
The I Ching also contains a line that has stayed with me: “井渫不食，为我心恻” — the well is clean, yet no one drinks from it; my heart is pained. The talented person unrecognized by the world — this is the enduring lament of thinkers across centuries.
But what I hold to is another teaching from the same text: “卑以自牧，含章可贞” — humble yourself to cultivate virtue; harbor brilliance within, and persevere. Research is a long act of self-cultivation. Good work may not be seen immediately, but if the water is clear, someone will drink from it, in time.
In my leisure, I write essays, read the classics, and capture fleeting light through a camera. This book — On Destiny — gathers years of reflection on fate, freedom, and chance. Photography, meanwhile, is another way of seeing: beyond models and numbers.
本文基于2011—2021年中国289个地级市的面板数据，运用面板回归、分位数回归、空间杜宾模型和双重差分等方法，实证检验了数字经济对地区共同富裕的影响。研究发现：第一，数字经济发展对地级市层面共同富裕有显著促进作用，且在非主要城市、中部地区和共同富裕水平较高的地区更为突出；第二，数字经济通过促进创新和提升基本公共服务水平两大机制推动共同富裕；第三，数字经济对共同富裕有显著的正向空间外溢效应，一个地区的数字经济发展也能带动邻近地区的共同富裕提升；第四，以智慧城市试点为代表的政策显著提升了参与城市的共同富裕水平。本文为数字经济赋能共同富裕提供了地级市层面的实证证据。
