How information and communication technology drives (routine and non-routine) jobs: Structural path and decomposition analysis for China

Abstract

A comprehensive exploration into the routine/non-routine job implications of information and communication technology (ICT) is crucial for tackling routine-replacing technological change challenges in the digital era. To this end, we propose an integrated input-output (IO) analytical framework to detangle the intertwined relations between ICT and non-ICT sectors, and further incorporate structural path analysis (SPA) and structural decomposition analysis (SDA) to examine the extent to which and how ICT sub-sectors drive the formations and changes of embodied routine/non-routine jobs in ICT. An empirical study using China's national IO tables from World Input-Output Database and the matched occupational employment data derived from 2000 and 2010 Population Census is conducted. We find that China's ICT growth over 2000–2010 has not led to a decline in jobs, which still holds true for both ICT manufacturing and ICT service, as well as for routine/non-routine jobs. We also find an increase in the embodied employment share of non-routine relative to routine jobs. The typical paths “source sector → (intermediate sector) → ICT final demand” generate many routine/non-routine jobs, which are primarily lied in the zero and first rounds. The decomposition results show that the declining sectoral routine/non-routine job coefficients drives the decline of both ICT embodied routine and non-routine jobs (especially the former), which is completely offset by the rising final demand of ICT. The proposed integrated IO analytical framework could also be applied to other indicators and extended to multi-country/region analysis.
