本文从城市空间依赖性角度,通过广义矩(GMM)估计,利用环渤海9城市数据,研究了该地区外资集聚。通过实证检验发现,城市外资集聚对邻近城市外资集聚影响不显著,城市化水平以及市场规模对城市外资集聚有显著影响。
From the perspective of urban spatial dependence, this paper studies the foreign capital agglomeration in this area by using the generalized moment (GMM) estimation and the 9 cities around the Bohai Sea. Empirical tests show that the concentration of urban foreign capital has no significant effect on the concentration of foreign capital in neighboring cities. The level of urbanization and the size of the market have a significant impact on the concentration of urban foreign capital.
