My research lies at the intersection of development economics and political economy, investigating how institutions form, change, and shape the long-run trajectory of economic development.

Current Research Interests

  • Informal Institutions and Market Formation: The role of cultural norms, social trust, and custom in the emergence of market economies
  • Political Economy of Institutional Change: Power structures, interest groups, and mechanisms of institutional lock-in
  • History of Economic Thought: Classical political economy, Austrian economics, modern Chinese economic thought

Methodology

Quantitatively, I employ microeconometric methods (DID, IV, RDD) and panel data analysis; qualitatively, I value archival research and textual interpretation of intellectual history. I believe good economic research requires the dual support of quantitative evidence and historical insight.

数字经济如何促进地区共同富裕——基于中国地级市的实证检验

宋立  ·  2024   Working Paper

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。
