 China is driving the transition away from internal combustion engine vehicles (ICEVs) to plug-in electric vehicles (PEVs, including plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs)) to address its pressing energy security and environmental pollution problems. The recent enactment of the dual-credit scheme mandate will compensate for the phase out of the subsidy program, while ostensibly shifting the burden of filling in the cost gap between PEVs and ICEVs from the government to the automakers (though in practice to car buyers). We estimate that creating an inflection point for PEV demand via the mandate will put substantial transition costs on the society-on average on the order of 100 billion Yuan per year from 2021 to 2030, consuming about 0.1% of China's growing GDP each year; these transition costs should be compared to societal benefits of PEVs (e.g., enhanced energy security, climate change mitigation, and improved public health) to evaluate the net social value of vehicle electrification. The consumer-centric total cost of ownership (TCO) is investigated using the local data: thanks to the generous subsidies, China's subsidized PEVs are in TCO parity with counterpart ICEVs from 2016 to 2020. Nevertheless, after subsidies are eliminated at the end of 2020, this TCO parity is unlikely to be achieved for BEVs, if the automakers keep the same price structure as today. The range of TCO ratio of BEV to ICEV for 2030 is: a lower quartile of 1.03; median of 1.07; and upper quartile of 1.10. It is uncertain how the cost gap will be covered when the subsidies are removed. However, automakers are expected to use internal subsidies to lower PEV prices and raise ICEV prices as needed to achieve the mandated percentage of sales.
