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　effects.　©　2017　Shandong　Normal　University.
