摘要：The past two decades have witnessed remarkable progress in China's electric vehicles (EVs). This paper first documents the dynamic evolution in China's EV industrial policies in both EV R&D grants and EV purchase subsidies. We then develop a two-country-two-technology industry equilibrium model with directed and step-by-step innovation to formally theorize the impact of polices in a global context. In the model, the initial technology gap in EVs is much smaller than the counterpart in gasoline vehicles (GVs) between Home (China) and Foreign, which, together with environmental considerations, incentivizes both government and private producers in Home to switch lanes to EVs to leapfrog. Optimal policies feature front-loaded EV R&D subsidies and hump-shaped EV purchase subsidies. The purchase subsidy rate is initially low as it would accrue profits to foreign producers when domestic EV technology lags behind, and eventually phases out when the EV relative price is sufficiently low. We further examine the interaction between subsidies and trade policies.
