中文摘要：

笔者将一个区域主动使其邻居区域产生的空间外部性转化为本区域增长动力的能力大小定义为利用能力,采用复合权重SDM模型,从理论和实证层面分析目标区域对空间外部性利用能力差异导致受到相同空间外部性影响的目标区域中的增长速度差异,揭示空间外部性影响区域经济增长的路径,并从中获得有益于区域经济增长的政策启示：一方面,区域应积极主动利用外部性和利用能力;另一方面,可以从提高人力资本存量和质量等多个层次提升区域利用能力。

英文摘要：

Utilization Capabilities is defined as the ability to initiatively transform the spatial externalities generated by neighbor regions into the capacity of the region＇s own economic growth. Based on the theoretical and empirical analysis,the composite SDM model is used in the paper to analyze how the difference of utilization rate lead to the different growth rate of the target area which is affected by the same spatial externalities. The paper reveals the effect of spatial externalities on regional economic growth,and has gained the political enlightenment on promoting economic development. On the one hand,the area should act more proactively in use of spatial externalities and utilization capabilities. On the other hand,to enhance the regional utilization capabilities,the area could improve the quantity and quality of human capital.
