讲座摘要：

I study the differential impacts of product innovation and process innovation on the labour market.  Using European data from 2000 to 2018, I find that industries with proportionally more firms reporting product innovation than process innovation also tend to exhibit a lower income share of low-skilled workers.  To better understand the mechanism, I develop a dynamic growth model in which firms conduct both types of innovation endogenously.  In the model, product innovation introduces new intermediate goods, which tend to require high-skilled workers to implement.  Process innovation simplifies existing production technologies and thereby allows firms to replace high-skilled workers with low-skilled ones.  I calibrate an extended version of the model to the largest two industries in UK in 2014 and 2018, respectively.  I find that product innovation has become less costly but increasingly demanding for skills,and the cost of process innovation has increased on average and become more diverse across firms.
