Summary
为了研究电动汽车的广泛使用对社会产生的影响,本文选取环境、经济、健康三个指标,建立了层次分析模型.通过权重计算和指标评估,定量分析了电动汽车的广泛使用对各方面的影响,综合评价出电动汽车的使用将会在2030年对美国加州社会环境有12.5%的改善效应.【具体说明了政府和制造商在决定是否支持电动车的发展时需要考虑的关键因素】.
考虑到电动汽车的使用程度和电的生产中来自煤的比例,建立模型二估算出了不同情况下二氧化碳的排放量,进而推算出可以节约的石油数量.随着电动汽车使用程度的增加和电的生产中来自煤的比例的减少,预测到2030年美国汽车行业排放到大气中的二氧化碳将减少 %,石油资源节约 %.
电的生产可以来源于不同的资源,不同资源的数量、发电的能源转换率和经济成本并不相同.为了满足大量新增电动汽车对电的需要,电网新增电力还需要在对社会产生最大效益的情况下进行合理配置.模型三建立了线性规划模型,以社会经济总成本最小为优化目标,各资源数量存量限制为约束条件,得出到2030年美国的最优电力构成,其中煤电和天然气电将分别减少到33%和10%,核能和可再生能源发电量将增加到47%和10%.
最后,综合考虑以上模型分析过程和结果,对政府在交通安全、效率、效果方面所应扮演的重要角色予以评估和提出建议.并指出未来电动汽车的广泛应用在解决全球石油资源日益枯竭方面将会发挥不可替代的作用.

Summary
为了研究电动汽车的广泛使用对社会产生的影响,本文选取环境、经济、健康三个指标,建立了层次分析模型.
In order to research the impact on the society due to the wide use of electric vehicle, this article selects environment, economy and health as 3 indexes and builds up a hierarchical analysis model.
通过权重计算和指标评估,定量分析了电动汽车的广泛使用对各方面的影响,综合评价出电动汽车的使用将会在2030年对美国加州社会环境有12.5%的改善效应.
Through weight calculation and index evaluation, it qualitatively analyzes the impact on each aspect due to the wide use of electric vehicle, and comprehensively evaluates that the wide use of electric vehicle will result in the 12.5% ameliorative effect on the social environment of California, USA, in 2030.
【具体说明了政府和制造商在决定是否支持电动车的发展时需要考虑的关键因素】.
(it expressly illustrates the key factors to be considered when the government and manufacturers are going to decide whether or not support the development of electric vehicle. )
考虑到电动汽车的使用程度和电的生产中来自煤的比例,建立模型二估算出了不同情况下二氧化碳的排放量,进而推算出可以节约的石油数量.
Considering the use level of EV and the proportion of mine used for electricity generation, it builds up Model Ⅱ to estimate the discharge amount of CO2 in different situations and eventually calculate the amount of oil to be saved.
随着电动汽车使用程度的增加和电的生产中来自煤的比例的减少,预测到2030年美国汽车行业排放到大气中的二氧化碳将减少 %,石油资源节约 %.
With the increase of EV use level and the decrease of coal proportion used for electricity generation, it is estimated that the CO2 discharged into the air by the US automobile industry will be reduced by % and the oil resources will be saved by % by 2030.
生产可以来源于不同的资源,不同资源的数量、发电的能源转换率和经济成本并不相同.
The generation can be from different recourses and the energy conversion rate and economic cost of amount and electricity generation of different resources is different.
为了满足大量新增电动汽车对电的需要,电网新增电力还需要在对社会产生最大效益的情况下进行合理配置.
In order to meet the demand for electricity used by the new large number of EV, the newly-added electricity power of electricity grid has yet to make a rational allocation, besides making a maximum benefit to the society.
模型三建立了线性规划模型,以社会经济总成本最小为优化目标,各资源数量存量限制为约束条件,得出到2030年美国的最优电力构成,其中煤电和天然气电将分别减少到33%和10%,核能和可再生能源发电量将增加到47%和10%.
Model Ⅲ builds up the linear programming model, takes the minimum total cost of social economy as optimization objective and the limitation of storage amount of each resource the constraint condition and eventually comes to the optimum electricity power structure of US in 2030, of which coal power and natural gas power will reduce to 33% and 10% respectively, and nuclear power and renewable energy sources power will increase to 47% and 10% respectively.
最后,综合考虑以上模型分析过程和结果,对政府在交通安全、效率、效果方面所应扮演的重要角色予以评估和提出建议.
Finally, the analytic process and result of the said models will be comprehensively taken into consideration and eventually the important role the government should play in the traffic safety, efficiency and effect will be evaluated and suggestion will be given.
并指出未来电动汽车的广泛应用在解决全球石油资源日益枯竭方面将会发挥不可替代的作用.
In addition, in the future the wide use of EV will play an irreplaceable part in dealing with the gradual dying up of global oil resources.
