异质性、贸易一体化与空间不平等
Heterogeneity, trade integration and spatial inequality
AI总结：
该研究构建消费者跨区域流动且具区位异质性偏好的模型，发现贸易一体化程度提升及区位偏好异质性增强均会推动经济活动空间分布更均衡，降低区域空间不平等。
摘要：
我们在一个所有消费者均可跨区域流动、且对居住区位选择存在异质性偏好的模型中，研究经济一体化对集聚的影响，这种异质性是模型中唯一的分散力。研究表明，在消费品品种间替代弹性的合理取值下，更高的贸易一体化始终会推动更对称的空间格局，降低区域间的空间不平等，且该结论与分散力的函数形式无关。我们还发现，区位偏好异质性程度的提升会使经济活动的空间分布更均衡，进而同样降低区域间的空间不平等。
英文摘要：
We study the impact of economic integration on agglomeration in a model where all consumers are inter-regionally mobile and have heterogeneous preferences regarding their residential location choices. This heterogeneity is the unique dispersion force in the model. We show that, under reasonable values for the elasticity of substitution among varieties of consumption goods, a higher trade integration always promotes more symmetric spatial patterns, reducing the spatial inequality between regions, irrespective of the functional form of the dispersion force. We also show that an increase in the degree of heterogeneity in preferences for location leads to a more even spatial distribution of economic activities and thus also reduces the spatial inequality between regions.
