我们表明，在多个国家的经济空间中，无论是名义收入还是实际收入，空间不平等都是普遍存在的，因为只有在国家按人口区分时才会出现空间不平等。在不存在任何可自由交易的同质商品的情况下，我们构建了一个新的贸易理论模型，从而可以考察国内市场效应以及收入不平等与全球化之间的非单调关系。同时，根据公司份额、劳动力工资和贸易模式，HME对两国空间有三种定义。前两个仍然适用于多国空间，而且它们被证明是等价的。然而，第三个概念的自然延伸并不等同。
We show that spatial inequalities in an economic space of multiple countries in terms of both nominal income and real income are ubiquitous in the sense that they appear when countries are differentiated by population only. A new trade theory model is constructed without any freely traded homogeneous good, so that we can examine the home market effect (HME) and the non-monotonic relation between income inequalities and globalization. Meanwhile, there are three HME definitions for a two-country space in terms of firm share, labor wage, and trade pattern. The first two remain applicable in a multicountry space, and they are shown to be equivalent. However, a natural extension of the third is not equivalent.
