论文摘要
我们开发了一个两个区域的经济地理模型，其垂直创新可提高每个地区生产的生产品种的质量。创新的机会取决于\ emph {相关的变体}，即研究人员之间相互作用的重要性，而不是在不同区域之间。随着经济一体化的较低水平的增加，较高的相关品种与更集聚的空间配置有关。但是，如果与外国科学家的互动对创新相对重要，则经济活动可能（完全）在初始阶段的聚集阶段后重新分散，因为在工业化较少的地区，创新机会更高的相对重要性的增加。经济整合与空间失衡之间的这种非单调关系可能表现出非常多样化的定性特性，尚未在文献中进行描述。
We develop a two-region economic geography model with vertical innovations that improve the quality of manufactured varieties produced in each region. The chance of innovation depends on the \emph{related variety}, i.e. the importance of interaction between researchers within the same region rather than across different regions. As economic integration increases from a low level, a higher related variety is associated with more agglomerated spatial configurations. However, if the interaction with foreign scientists is relatively more important for innovation, economic activities may (completely) re-disperse after an initial phase of agglomeration due to the increase in the relative importance of a higher chance of innovation in the less industrialized region. This non-monotonic relationship between economic integration and spatial imbalances may exhibit very diverse qualitative properties, not yet described in the literature.
