The potential mechanism suggests that the NEV adoption reduces regional energy efficiency differences by promoting inter-provincial electricity transmission and spurring renewable energy development

This means that when more people adopt NEVs, there is an increased demand for electricity, which encourages electricity to be transmitted between provinces. This transmission can help balance out the energy efficiency differences between regions, as some provinces may have more access to renewable energy sources than others. Additionally, the increased demand for electricity can lead to more investment in renewable energy development, further reducing the reliance on fossil fuels and promoting sustainable energy practices. Overall, the adoption of NEVs can have a positive impact on regional energy efficiency and contribute to a more sustainable energy system.
