赵浩等：global firms and emissions: investigating the dual channels of emissions abatement
发布时间：2023-01-17
abstract：
this paper finds that both importing and exporting reduce firm-level emission intensities. we develop a theoretical model in which firms jointly determine the extent of abatement investment as well as whether or not to import intermediate inputs and export final goods. the model demonstrates a complementarity between trading decisions and abatement investment such that trading firms invest more in abatement technology and feature lower emission intensities. using chinese firm-level data, we estimate a theory-based regression model with instrument variables to account for the endogeneity issue associated with firms’ trading statuses. our regression results show that both importing and exporting reduce firm-level emission intensities by over 15 percent.
