行政空间邻接与土地财政传导效应——基于武汉城市圈实证分析
Administrative Spatial Adjacency and Land Fiscal Conduction Effect——A Case Study on the Wuhan Metropolitan Area

以武汉城市圈为例，基于行政地位对土地财政具有空间效应的假设，根据不同行政地位（主城区、远郊区、区、县级市、县）的土地出让金差异划分归类，在分析不同类别行政区的空间邻接关系的基础上，嵌入多策略的空间权重矩阵建立空间滞后模型，研究行政空间邻接关系对地方政府土地财政收入的重要作用。结果显示：人均GDP、城镇居民人均可支配收入、地均固定资产投资和土地财政高度正相关，第二产业增加值占比、地均财政收入对土地财政产生负向影响；土地财政受不同行政地位之间空间传导效应的影响，2013年、2015年土地财政在处于中心城区附近的主城区与远郊区、区之间的空间互动性更强，这一发现肯定了相对落后地区对土地财政的依赖性，强行政权力地区拥有最具价值的土地发展机会。
Based on the assumption that administrative status has the spatial effect on land finance,this paper analyzes how important the administrative spatial adjacency is to the land fiscal of local governments. Taking Wuhan as an exmaple,this paper classifies its surbodinat areas (urban district,suburban area,district,county-level cities and counties) according to their land sales,analyzes the spatial adjacency of different districts and constructs the spatial lag model. The results show that:The per capita GDP,per capita disposable income of urban residents,per capita capital investment in fixed assets and per capita fiscal revenue are highly correlated with the changes of the land revenue; the proportion of the secondary industry increases and per capita fiscal revenue imposes negative effects on land finance; land finance is associated with the conduction effect between different administrative positions. In 2013 and 2015,land finance interacted with the urban district and suburban district or district near the central urban area,which confirmed the dependence of the backward regions on land fiscal,areas with strong administrative power have the most valuable land development opportunities.
