How does an economy rebalance economic production and environmental preservation when its ability to generate income using environmental resources changes? Theoretically, we predict that an increase in the ability can have heterogeneous impacts on the economy’s environmental quality and income. Empirically, we find that the dramatic expansion of China’s national expressway system, which arguably enhanced the income-generating abilities of Chinese counties, indeed affects their economic and environmental performances differentially: expressway access increases pollution and GDP in initially poor counties, reduces pollution and GDP in initially rich counties, and reduces pollution while increasing GDP in counties with middling income levels.
