经鸿之粟｜龚关常任教授合作论文在经济学国际一类期刊在线发表

This paper studies Chinese firms' export status, distinguishing state and privately controlled enterprises. A dynamic model of export decisions is estimated by ownership types. The estimated models capture distinctive differences between ownership types including the productivity gap between exporters and nonexporters, the interaction between domestic and foreign sales, the skewed distribution of export shares, and the dynamic response of employment to changes in export status. Our analysis highlights the crucial role of demand shocks and labor adjustment costs in shaping the dynamics of export status, especially for privately controlled enterprises. The estimated model is used to study tariffs and uncertainty.
