As the largest soybean importing country, this study analyzes the migration effect of soybean import shock in China. Exploiting the main soybean producing areas, the three northeastern provinces in China as our sample and using population Census data, we constructed prefecture-level soybean import shock and individual level migration variables. We found a large out of migration effect caused by soybean import shock: 13% of the rural migration of northeastern regions over 2001-2010 can be explained by the soybean import shock. The shock reduces (increases) soybean planting (land renting) activities, leading rural residents to seek opportunities in other more developed regions mainly by becoming migrant workers. Such migration-to-elude effect is largely driven by low educated and mature farmers.

Chinese central and provincial state-owned enterprises (SOEs) were exempt from local environmental regulations because of an institutional barrier. This exemption pushed local regulators to impose more stringent regulations on private firms. We use rich firm-level panel data and exploit the decentralization of Chinese central and provincial SOEs to explore the direct and spillover effects of removing this regulatory constraint. We report that a polluting SOE invests more in unproductive pollution abatement inputs and therefore pollutes less and has lower productivity when decentralized to the prefectural level; moreover, private firms in the same prefecture pollute more while increasing output and TFP. The spillover effects are stronger among private firms with more binding financial constraints. At the aggregate level, decentralization of polluting SOEs in a prefecture decreases total emissions without a significant negative effect on total industrial output or aggregate productivity. When hypothetically reallocating 10% of emissions from central and provincial SOEs to private firms, we calculate total industrial output gains of 0.74–3.31%.
