市场转移与经济地理:一般化的要素流动空间经济模型

Mobile Market and Economic Geography:A Generalized Factor Flow Spatial Economy Model

文章通过引入衡量流动要素收入流与支出流空间同步程度的“市场转移指数”的指标,构建了一般化的要素流动模型。结论显示,市场转移指数与区际贸易成本在决定长期空间经济均衡方面存在“替代”关系,当贸易成本既定时,市场转移指数同样可能引发空间均衡的集聚突变,同时产生与贸易成本类似的其他空间经济标杆效应。此外,“自由资本”和“自由企业家”成为本模型框架下的两个特例。

This paper builds a generalized factor flow model by introducing a ＂mobile market index （MMI）＂ measuring the spatial synchronization degree of income stream and expenditure flow. The results show that MMI and interrcgional trade cost have a ＂substitution＂ relationship in determining long-run spatial economic equilibrium. And when the trade freedom is fixed MMI can also cause an accumulation mutation of the spatial equilibrium, and simultaneously generates other spatial economic benchmarking effects similar to the cost of trade. In addition, ＂free capital＂ and ＂free entrepreneur＂ are two special cases under the framework of this model.
