【摘要】：紧凑城市作为应对城市无序蔓延发展的可持续发展模式,在西方欧美等国家已被普遍认可。然而在我国快速城市化背景下,紧凑城市模式是否也适用于我国呢?本文基于我国217个地级市统计数据,实证探究了交通影响下的城市紧凑度对城市生产率的影响。首先,运用熵值法,综合计算出217个地级市从1999年至2012年的城市紧凑度;然后运用面板固定效应模型和差分GMM模型构建了城市交通-城市紧凑度模型,实证得出交通对城市紧凑度的提高具有显著影响,特别是公共交通的作用更加明显,但这一影响效应存在时间滞后性;最后,通过构建交通-城市紧凑度-生产率模型,得出城市紧凑度高的城市趋向于拥有更高的城市生产率,交通因素既直接影响城市生产率,也通过影响城市紧凑度对生产率产生间接影响。这些结论为我国施行紧凑城市发展战略提供了科学依据。紧凑集约发展模式应当成为我国新型城镇化的有效模式和实现途径。
[Abstract]:Compact city, as a sustainable development mode to cope with urban sprawl, has been widely accepted in western countries, such as Europe and America. However, in the context of rapid urbanization in China, is the compact city model also applicable to China? Based on the statistical data of 217 prefecture-level cities in China, this paper empirically explores the effect of urban compactness on urban productivity under the influence of traffic. Firstly, the compactness of 217 prefectural cities from 1999 to 2012 is calculated by using entropy method, and then the urban traffic-city compactness model is constructed by using panel fixed effect model and differential GMM model. The empirical results show that traffic has a significant impact on the increase of urban compactness, especially on public transport, but this effect has time lag. Finally, by constructing a model of traffic, urban compactness and productivity, It is concluded that cities with high urban compactness tend to have higher urban productivity. Traffic factors not only directly affect urban productivity, but also indirectly affect productivity by influencing urban compactness. These conclusions provide scientific basis for the implementation of compact city development strategy in China. Compact and intensive development mode should become the effective mode and realization way of new urbanization in our country.
