论文摘要
经济学家对成长理论的兴趣具有很长的历史（Harrod，1939; Domar，1946; Solow，1956; Swan 1956; Mankiw，Romer和Weil，1992）。最近，从新古典的增长模型开始，Ertur和Koch（2007）使用外在的空间重量矩阵（$ W $）开发了空间增强的Solow-Swan增长模型。尽管只有在地理/物理距离的情况下，外源性$ w $假设才能是正确的，但是当经济/社会距离发挥作用时，这可能并不是真的。使用佩恩世界桌7.1版，涵盖1960 - 2010年，我进行了强大的Rao得分测试（Bera，Dogan和Taspinar，2018），以确定$ W $是否为endogeonus，并使用了最大似然估计（QU和Lee，2015年）。关键发现是，在Ertur和Koch（2007）中，物理资本外部性和空间外部性（技术相互依存）的重要性和积极影响不再与外源性$ W $一起发现，但他们仍然与内源性$ W $模型一起发现。我还发现了一种经验策略，当数据最近在1996 - 2010年期间全球金融危机严重冲击时，经济距离进行了使用。
Economists' interests in growth theory have a very long history (Harrod, 1939; Domar, 1946; Solow, 1956; Swan 1956; Mankiw, Romer, and Weil, 1992). Recently, starting from the neoclassical growth model, Ertur and Koch (2007) developed the spatially augmented Solow-Swan growth model with the exogenous spatial weights matrices ($W$). While the exogenous $W$ assumption could be true only with the geographical/physical distance, it may not be true when economic/social distances play a role. Using Penn World Table version 7.1, which covers year 1960-2010, I conducted the robust Rao's score test (Bera, Dogan, and Taspinar, 2018) to determine if $W$ is endogeonus and used the maximum likelihood estimation (Qu and Lee, 2015). The key finding is that the significance and positive effects of physical capital externalities and spatial externalities (technological interdependence) in Ertur and Koch (2007) were no longer found with the exogenous $W$, but still they were with the endogenous $W$ models. I also found an empirical strategy on which economic distance to use when the data recently has been under heavy shocks of the worldwide financial crises during year 1996-2010.
