您好,请问下,一国GVC位置指数该怎么计算?是=PlxGVC /plyGVC么? length文件里只有分行业的那两组数据, ...
关注以下几个文件

PLsrby year (G by G matrix per year) average bilateral production length between country s and r
PLsrby year_brsec (G by G matrix by 4per year) average bilateral production length between country s and r for Agriculture, Mining, Manufacture and Services
PLsby year (G by 1 per year): average production length of country s
