大国内部经济空间布局:区位、禀赋与一体化

Distribution of Economic Activities in Big Country: Location, Endowments and Integration

本文建立三地区新经济地理学模型,设定非对称的城市间距离以刻画城市体系的空间结构,揭示区域一体化、地理区位和资源禀赋对经济活动分布的影响机制。研究发现,随着区域一体化推进,经济空间分布依次为向中心城市集聚、向城市群集聚和向偏远地区扩散。在城市群内部,区域一体化水平决定中心城市对周边中小城市会产生极化效应还是辐射效应。此外,区域一体化有利于降低偏远地区的区位劣势并提升其禀赋优势对地方发展的相对作用。

A New Economic Geography model of three regions is established to reveal the influencing of integration, geographical location and resource endowments on the distribution of economic activities. With the improvement of regional integration, the economic distribution successively concentrates to the central city, to the urban cluster and to the remote areas. Within the urban cluster, the level of regional integration determines whether the central city has polarization effect or radiation effect on the surrounding cities. In addition, regional integration can reduce the regional disadvantages of remote areas and improve the relative effect of their endowment advantages on local development.
