研究各地区投入产出表与区域间投入产出模型的关系,从需求角度将多个区域视为一个系统,运用区域购买力系数思想定量分析其各部门产品对外输入输出的可能性及流量,并根据投入产出综合平衡关系,通过建立区域间投入产出模型将已有的各地区投入产出表联结成为区域间投入产出表,并采用非参数估计方法对模型准确性及各类误差的影响程度进行分析。该模型为利用投入产出模型分析区域间产品流动提供一种新的可行方法,适用于国家和区域统计系统相关年份数据供给不足情况下对区域间产品流动的初步估计。
Study the relationship between input-output tables and input-output models in different regions, regard multiple regions as a system from the perspective of demand, and use the idea of regional purchasing power coefficient to quantitatively analyze the possibility and flow of external input and output of each department’s products According to the comprehensive balance of input-output relations, the existing input-output tables of all regions are established as inter-region input-output tables by establishing an inter-region input-output model, and the accuracy and error of the models are estimated by non-parametric estimation methods Impact analysis. This model provides a new and feasible method for analyzing the inter-regional product flows using the input-output model and is suitable for the preliminary estimation of the inter-regional product flows under the conditions of insufficient data supply in the relevant national and regional statistical systems.
