请问楼主的弹性取的是几呀

Based on a review of the literature, elasticity of substitution is set to 8 across all sectors (both agriculture and manufacturing) in
the database. See Staff Working Paper 5/2011 for details. Even though trade costs are sensitive to elasticity of substitution, the
change of trade costs are not. See Novy (2008) for more details.

这个是计算方法说明里的，取得是8
