中国的城市化与城市扩张、农村人口迁移密切相关，政府在推动城市化进程中的作用更为直接和有力。2014年，《中国新型城镇化规划》发布，城市群和中小城市的发展成为重点。在此背景下，本文将城市化分解为人口主导型和土地主导型两种原型，并以武汉城市圈为例，构建了嵌入不同空间关系的多策略空间模型，揭示了城市化的潜在驱动力。本文的主要贡献在于，通过在空间建模中引入不同情景下的空间权重矩阵，对行政影响力进行测度，具体而言，就是对城市区、市级县、县级市的行政影响力进行测度。研究发现：1）非农业人口和城市用地均表现出显著的空间自相关性，且城市中心区的优势明显; 2）社会经济发展和交通建设对城市化的影响显著，其中个人收入和固定资产投资所占比重最大;（3）县级行政地位的差异是不可忽视的因素，市区与县级市相邻时，城市面积扩大的可能性较大;（4）这种行政地位的影响力一般会增长到一定程度，然后达到一个平台。这些研究结果为理解新型城镇化中的行政维度提供了理论依据，并对行政调整和城市群建设具有重要的政策意义。
Urbanization in China has been closely associated with urban sprawl, rural migration and the role of government has been more direct and powerful in setting it in motion. In 2014, the New Urbanization Planning in China has been released in which the development of urban agglomeration and small-medium cities has been highlighted. In this context, we decompose urbanization into population-oriented and land-centered archetypes and devise spatial models in multiple strategies embedded with different spatial relations to unfold the underlying driving forces using Wuhan agglomeration as the case. In addition to the identification of major driving forces which are gross domestic product (GDP), income, fixed asset investment and the transportation construction, the major contributions of our study lie in the gauge on administrative influence, to be more specific, the status of urban district, city-level county and county, through incorporating different spatial weight matrix in different scenarios in spatial modeling. It found out that 1) both non-agricultural population and urban land exhibit significant spatial autocorrelation and the superiority in the city center is evident; 2) socio-economic development and transportation construction significantly influence urbanization whereas the personal income and fixed asset investment accounting for a large proportion being the most powerful factors; 3) different administrative status at the county level is an unneglectable factor and urban area has higher probability to expand when urban district is adjacent to county-level city; 4) the magnitude of this administrative status influence generally grows to a certain level and then reaches to a plateau. These findings provide theoretical basis for understanding the administrative dimension in new urbanization and have important policy implications on administrative adjustment and urban agglomeration.
