This paper examines the impact of innovation on migration patterns across skill groups, taking into account labor market, housing market and amenity responses. Utilizing data from the Chinese Census spanning 2005 to 2015, we find that cities experiencing higher patent growth attract more low-skilled than high-skilled migrants, a pattern that contrasts with findings from other developed countries. These cities also exhibit stronger wage growth for both low- and high-skilled workers, but not faster growth in amenities. Our analysis indicates that low-skilled workers prioritize wages more highly, whereas high-skilled workers place greater value on amenities. As a result, a positive shock to patent activity draws in more low-skilled than high-skilled workers, leads to a reduction in amenities, and thereby further discourages high-skilled migration. Counterfactual analysis suggests that technological growth in China has substantially increased wages and welfare for both groups of workers.
