Experimental results on the MovieLens, Netflix, and RYM datasets show that, the IMD method greatly improves both the recommendation accuracy and diversity, compared with a heterogeneity-weakened MD method（HMD）, which only considers the source object heterogeneity. Moreover, the recommendation accuracy of the cold objects is also better elevated in the IMD than the HMD method. It suggests that eliminating the redundancy induced by the indirect linkages could have a prominent effect on the recommendation efficiency in the MD method.展开更多

It is frequently assumed that increasing returns are absent at the firm level while present at the industry level. In this model, the existence of increasing returns at the form level is necessary for the existence of external economies at the industry level. We show that the degree of external economies increases with the level of linkage effects. However, a higher linkage effect does not always lead firms to choose more specialized technologies.展开更多

文摘Is the degree of external economies （at the industry level） higher than the degree of internal increasing returns （at the firm level）？ If so, what is the exact source of this difference？ In the general equilibrium model in which firms producing final goods choose the degree of specialization of their technologies, external economies arise from the usage of intermediate inputs and the existence of internal increasing returns. It is frequently assumed that increasing returns are absent at the firm level while present at the industry level. In this model, the existence of increasing returns at the form level is necessary for the existence of external economies at the industry level. We show that the degree of external economies increases with the level of linkage effects. However, a higher linkage effect does not always lead firms to choose more specialized technologies.
