文章基于2007年收支分类改革后新的预算科目和278个地级及以上城市的数据,运用SLM、SEM、Durbin和SAC空间计量模型以及ML估计和工具变量GMM估计方法,通过设定相邻、地表距离和最临近三种空间地理矩阵以及工业化水平、土地出让金收入占比、房地产投资占比、城市化水平和FDI五种经济变量空间矩阵,对当前城市政府间公共投资类财政支出的策略互动情况进行了评估与甄别。结果发现,城市政府在相邻地理位置上的显著互动———以策略互补为主,具有特定的外部性范围和变化轨迹,而工业禀赋型、“土地”财政型和FDI型策略互动的影响则具有同质性,且总体低于以外溢效应和标尺效应为主要源泉的地理空间位置上的策略互动水平。最后,文章对相应理论和政策含义进行了探讨。
Based on the new budget subjects and 278 prefecture-level and above cities in the 2007 Revenue and Expenditure Classification, the paper uses SLM, SEM, Durbin and SAC spatial econometric models and ML and GMM estimation methods. By setting adjacent , The surface distance and the nearest three kinds of spatial geography matrix as well as the level of industrialization, the proportion of land transfer income, the proportion of real estate investment, the level of urbanization and the spatial matrix of FDI in five kinds of economic variables. Strategic interaction was assessed and screened. The results show that the significant interaction of urban government in the adjacent geographical position --- mainly complemented by strategy, has a specific range of externalities and changes in trajectory, while industrial endowment, “land ” financial and FDI type strategy interaction Are less homogeneous than those in the geospatial position with spillovers and scale effects as their main source of geospatial interaction. Finally, the article discusses the corresponding theoretical and policy implications.
