The polyphony: Historical migration and contemporary innovation

Abstract:

This paper studies the impacts of the historical influx of inter-provincial immigrants in a prefecture on contemporary innovation in China. To explore the causal effect, we exploit both the provincial variation in the migration influx and the temporal variation in the main road network expansion. The results indicate that prefectures with more historical migrant influx persistently produce higher number of patents, own more innovative firms and cultivate more academicians nowadays. Mechanism analysis suggests that the influx of migrants introduced diversity and competition into the local area, fostered open attitudes towards new ideas and placed a greater emphasis on education, ultimately resulting in a “polyphony” effect. To rule out the influence of inner migration in China in recent decades, we present evidence that this effect has already appeared in the early stage of modern science diffusion in early 20th century.
