The Spatial Diffusion of Secondary Impacts: Rural-Urban Spillovers in Grampian, Scotland
使用双区域社会核算矩阵模型分析城乡溢出效应，发现城市向农村的溢出更强，而投入产出模型可能产生偏差，建议采用更广泛的SAM框架研究城乡关系。
The paper analyzes rural-urban spillover effects using a bi-regional SAM model which allows for flows of commodities and factor incomes between the two areas. Multiplier decomposition is used to investigate the nature of spillovers. The results indicate stronger spillover effects from urban to rural Grampian, than viceversa. In contrast, results from a restricted, input output version of the model suggest that the effects are more consistent with nodal response. Input-output an alysem say produce biased results and studies of contemporary rural-urban relationships should look beyond production linkages to the broader range of relationships within a SAM framework
