专业化产业集聚、空间成本与区域工业化

本文扩展了贸易成本的范围，认为贸易成本不仅包括产品运输成本，而且也包括要素流动成本，并引入前后向产业联系，认为中间产品使用及种类的增加所创造的成本和需求联系效应有利于提高最终产品的生产效率。在此基础上文章发展了可解的中心一外围模型，并探讨了在各种条件下相应的经济学含义，认为在推动我国区域经济一体化的进程中，对落后地区的技术支持必不可少，重视区域间产业发展的互动，否则，我国区域经济一体化进程难以有效推进。

Specialized Agglomeration, Spatial Costs and Regional Industrialization

This paper expands the scope of the concept of trade costs to include not only product transportation costs, but also factor mobility costs. By introducing industrial forward and backward linkages, we set our premise on the idea that the number of intermediate goods creates cost and demand linkages between firms, resulting in a higher productivity of finalgoods production. We then develop a solvable core-periphery model and explore the economic connotations under various conditions of the model. Our results show that providing technological supports for the backward regions is essential and harmonized industrial development among regions should also be stressed in order to narrow regional disparities in China.
