摘　　要：介绍了Leontief模型和Ghosh模型前向关联的测度方法,利用中国2002年各省市投入产出表测度并比较了各种前向关联。无论是Leontief模型还是Ghosh模型,间接关联对前对各部门的排序影响不大。规模因素对Leontief模型中的虚拟消去前向关联的排序影响较小而对Ghosh模型中的虚拟消去法影响较大。各种前向关联存在一定程度的相关性,大多数前向关联相关性较高。资源型部门的前向关联较大,而具有比较优势部门的前向关联一般较小。This article introduced the measurement of forward linkages based Leontief model and Ghosh model,then measured all kinds of forward linkages using the tables of 30 provinces and cities of 2002.Not only Leontief model＇s but also Ghosh model＇s indirect linkages have little effects on the rank of sector＇s forward linkages.Scale factors have little effect on the rank of hepothetical extraction forward linkage of Leontief model but have some effect on the Ghosh model＇s.all the kinds of forward linkages have correlation to some degree,many have high correlation.Resource-based sector＇s forward linkages are larger,while sector with comparative advantage have small forward linkages.
