区域间的经济往来会产生多种影响,具体表现为三种效应:乘数效应、溢出效应和反馈效应(包括自反馈和互反馈)。三种效应中乘数效应是核心,通过列昂惕夫逆这一“放大器”的传导,产生了溢出效应并进一步导致自反馈和互反馈效应。笔者利用两地区的区域间投入产出模型,验证了这一传导机制的作用和影响,实证结果表明:三种效应因传导路径的远近依次递减,同时也受行业和区域经济规模影响,表现出不同特点。差别巨大的区域间的产业关联并非呈现一边倒现象,在适当的制度安排下,区域间的贸易往来可以获得更多的双边利益。
Economic interactions among regions have multiple effects, embodied in three effects: the multiplier effect, the spillover effect, and the feedback effect (including self-feedback and mutual feedback). The multiplier effects of the three effects are at the center of the spillover effect due to Leontief’s inverse “amplifier” conduction and further lead to self-feedback and mutual feedback effects. The author uses the interregional input-output model of the two regions to verify the effect and influence of this transmission mechanism. The empirical results show that the three effects are decreasing due to the distance of the transmission routes and are also affected by the economic scale of the industry and the region. Different characteristics. The industrial relations among the vastly different regions do not show the phenomenon of one-sidedness. Under appropriate institutional arrangements, the bilateral trade between the regions can gain more bilateral interests.
