Stages | Interpretation |
---|---|
Stage one (2010–2013): Pilot Demonstration Phase. | The government selects representative cities to serve as demonstration bases for the promotion of NEVs verifying the feasibility, performance, and market promotion potential of NEVs through on-site operation and testing. |
Stage two (2014–2016): Large-scale Promotion Phase. | The government mainly encourages the purchase of NEVs in more cities across the country through measures such as purchase subsidies, government procurement, exemption from purchase tax, and restrictions on fuel vehicles, promoting the large-scale development of the NEV industry. |
Stage three (2017–2019): Market Transition and Development Phase. | Purchase subsidies are gradually phased out, and market competition for NEV intensifies, focusing on improving product quality while promoting large-scale development. |
Stage four (2020–2023): High-quality Development Phase. | Purchase subsidies are canceled, and the “dual credit” policy is further revised and improved, with NEV paying more attention to technological innovation and product quality enhancement. |
