对于新能源汽车的推广和普及,从需求方来说,要从政策上引导,比如上海购买新能源车可销售免费牌照及现金补贴。北京市也可以单独搞一个新能源汽车的摇号队伍,但是牌照完全免费也不见得合理。因为虽然新能源汽车污染少,但在城市里交通拥堵也是一种污染,新能源汽车的增加也会产生交通堵塞。因此,建议可以先给新能源汽车一点空间鼓励其发展。 For the promotion and popularization of new energy vehicles, from the demand side, we should guide from the policy, such as Shanghai to buy new energy vehicles to sell free licenses and cash subsidies. Beijing can also engage alone in a new energy vehicles Yaohao team, but the license is completely free is not necessarily reasonable. Because although new energy vehicles have less pollution, traffic jams in the cities are also a source of pollution. Increases in new energy vehicles also cause traffic jams. Therefore, it is suggested that new energy vehicles should be given some space to encourage their development.
