摘要
通过建立动态模型,分析了不同城市类型下公共交通状况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公共交通状况的变好而减少;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;然而,在垄断市场条件下,公共交通状况对厂商第二阶段私家车最优供应数量的影响为常值.公共交通状况对厂商第一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.交通拥堵型城市公共交通状况对厂商第一阶段私家车最优供应数量的影响,强于交通良好型城市.
The paper analyzes the effect of the public transport conditions on the dynamic supply of private car manufacturers in different types of cities with one dynamic model.The optimal supply of private car manufacturers decreases with the improvement in public transport situation.In the competitive market,the effect weakens with the intensity of competition between the manufacturers.But in the monopolistic market,the effect in the second stage is constant.The effect in the first stage increases with the private cars depreciation rate and the externality.The effect for traffic congestion cities in the first stage is stronger than for cities with good traffic condition.
