Is pork trade good for China's greenhouse gas emissions?

摘要

China produces the largest amount of pork in the world,which emits the largest amount of greenhouse gases (GHGs).This paper calculates GHG emissions from China's hog production at the provincial level using newly published emission factors.Empirical results show that GHG emissions from China's hog production mainly respond to the scale intensity.Capital abundance and income contribute positively to GHG emissions from hog production.Pork trade increases GHG emissions from China's hog production with a significantly direct effect,reduces GHG emissions through indirect technique effcts.
