你好,想请问下应该怎么算行业大类整体的参与度和地位指数呀
UIBE提供如下整体行业的生产长度:
Aggregate production length
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
PLwby year: average production length of the world
看看有木有你想要的?
我没计算过,都是直接用的。
