摘要
针对城市交通状况,将私家车的耐用期作为研究期,并将其划分为2个阶段,通过建立动态模型,分析了燃油价格对私家车厂商动态供给的影响。厂商私家车的最优供应数量随着燃油价格的上涨而减少,并且燃油价格对厂商私家车最优供应数量的影响随着燃油消耗量的增加而增大;在竞争市场条件下,这种影响随着厂商之间竞争强度的增强而减弱。燃油价格对厂商第1阶段私家车最优供应数量的影响,随着私家车折旧率及外部性效应的增大而增大。交通拥堵型城市燃油价格对厂商第1阶段私家车最优供应数量的影响,强于交通良好型城市。
Considering the traffic conditions of cities,we regard the life span of a private car as two stages.We then construct a dynamic model to analyze the effects of the fuel price fluctuations on the dynamic supply of car manufacturers. When the fuel prices rise,the optimal supply of the car manufacturers decreases,and the effect increases when the fuel consumption increases.In the competitive market,the effect weakens with the enhancement of the intensity of competition between manufacturers.The effect on the dynamic supply of car manufacturers in stage one increases with the increase of the depreciation rate of the cars and the externality effect.The effect on the dynamic supply of car manufacturers in stage one is stronger in the cities with the strong traffic congestion than in the cities where the traffic conditions are good.
