摘要： This paper explores the issue of whether investment in information technology (IT) will bring about the Solow productivity paradox. The semiparametric smooth coefficient approach is applied to implement estimations considering how the non-neutral impact of IT might affect labor productivity and thus contribute to productivity. The empirical results are obtained employing firm-level manufacturing data from Taiwan to show that IT investment has as a significantly positive influence on productivity. Specifically, IT exhibits a significant spillover impact on promoting labor productivity in general, particularly for larger and more IT deepened firms. •This paper revisits Solow productivity paradox.•We apply the semiparametric smooth coefficient approach to implement estimations.•Results show that IT investment positively contributes to productivity in Taiwan.•IT has a non-neutral impact on promoting labor productivity and thus contributes to productivity.•The non-neutral impact of IT is more relevant to larger and more IT deepened firms. 出版者： New York: Elsevier Inc 出版日期： 2014-01 出處： Technological forecasting & social change, 2014-01, Vol.81, p.300-308 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2013 版權： Copyright Elsevier Science Ltd.
