摘要： •We investigate impacts of e-commerce and R&D on productivity in Taiwan.•The network externalities of e-commerce is constructed and tested.•We employ the system GMM to deal with the endogeneity of e-commerce adoption.•E-commerce and R&D capital have a positive influence on productivity.•The inter-industry network externality of e-commerce contributes to productivity. This study investigates the impact of e-commerce and R&D on productivity, using a unique panel dataset obtained from Taiwanese manufacturing firms for the period from 1999 to 2002. We specifically consider the network externalities of e-commerce and employ the system generalized method of moment (GMM) technique to deal with the endogenous problem of e-commerce adoption. The empirical results show that both e-commerce and R&D capital have a positive influence on productivity, while R&D exhibits a larger productivity-enhancing effect. We also find a complementary relationship between e-commerce and R&D on enhancing productivity. Crucially, the inter-industry network externality of e-commerce significantly contributes to productivity. 出版者： Amsterdam: Elsevier B.V 出版日期： 2013-12-01 出處： Information economics and policy, 2013-12, Vol.25 (4), p.272-283 版權： 2013 Elsevier B.V. 版權： Copyright Elsevier Sequoia S.A.
