论文摘要
在差异化农业中具有运输成本的核心外围模型扩展到连续空间。均匀的固定溶液是不稳定的，但显示出通过足够低的制造运输成本或对制造品种的足够强烈偏爱的重新分散。从数值上观察到，从不稳定的均匀溶液开始的溶液最终形成了尖峰样的聚集。此外，重新分散也出现在某种意义上，即随着制造业运输成本的降低，尖峰的数量从减小到增加。还可以观察到，农业运输成本较低，对农业种类的偏好更强。
The core-periphery model with transport costs in differentiated agriculture is extended to continuous space. A homogeneous stationary solution is unstable but exhibits redispersion that it is stabilized by sufficiently low manufacturing transport costs or sufficiently strong preference for manufacturing variety. It is numerically observed that a solution starting from around the unstable homogeneous solution eventually forms a spike-like agglomeration. Furthermore, the redispersion also appears in the sense that the number of the spikes goes from decreasing to increasing as the manufacturing transport costs decrease. It is also observed that lower agricultural transport costs and stronger preference for agricultural variety promote agglomeration.
