Does government R&D stimulate or crowd out firm R&D spending? Evidence from Chinese manufacturing industries

We examine whether receiving a government R&D grant stimulates or crowds out a firm's own R&D spending in Chinese manufacturing industries. Using a database that spans the population of large and medium size privately owned Chinese manufacturing firms for the period from 2007 to 2011, a matching estimator and a matching and difference in-differences estimator, we find a large firm R&D promoting effect of government R&D: receiving a government R&D grant led to a 4 to 9-million-yuan increase in a firm's own R&D expenditures. This is a significant effect since the average R&D expenditures ranged from 5 to 9 million yuan in the year before receiving the grant. To understand the mechanisms behind this effect, we compare the before- and after-treatment performance and behaviour of the treated and the control firms. We find that the government R&D receiving firms became more profitable following their receipt of the grant. We also find that receiving a government R&D grant increases the likelihood of a firm continuing its R&D performance after receiving the initial grant.
