This article examines the impact of innovation on labour productivity by using latest World Bank Enterprise Surveys data and compares the results between Chinese and Indian manufacturing sector. The article uses cross-section data based on two surveys that were conducted by the World Bank in 2012 and 2014 for China and India, respectively. By employing simple ordinary least squares (OLS) regression technique, we find that innovation affects the labour productivity positively for Chinese as well as Indian manufacturing firms, but its impact on firm productivity is relatively weak in case of India as compared to China. Second, other factors such as average wage of the workers, education of production workers and training do significantly boost the labour productivity of Chinese manufacturing firms as well as for Indian firms. Third, our results based on firm size also indicate that the impact of innovation activities on labour productivity is higher in case of large firms as compared to medium firms. However, innovation does not affect the labour productivity of small manufacturing firms for both China and India. In terms of policy, it is important for both Chinese and Indian manufacturing firms to keep pursuing innovation activities, in order to spur productivity, which would strengthen firms’ growth. © 2020 SAGE Publications.
