运输成本、异质性企业迁移与区域平衡发展——基于集聚与增长整合理论的研究

随着我国社会主要矛盾的转化,如何解释经济活动在空间维度的区位分布与时间维度的动态增长就成了当前面临的重要理论问题.本文基于集聚与增长整合理论,引入内生动态化运输成本影响微观异质性企业迁移机制,构建了一个分析区域交通政策影响企业空间区位选择和区域平衡发展的集聚与增长整合模型.研究发现:①较好的区际运输条件会提高异质性企业迁移门槛、降低核心区企业份额,有利于边缘区经济增长,进而缩小两区域经济差距;②较好的核心区区内运输条件会降低异质性企业迁移门槛、提高核心区企业份额、提高两区域经济增长速度,但同时会扩大两区域经济差距;③较好的边缘区区内运输条件也会降低异质性企业迁移门槛、提高核心区企业份额,但有利于边缘区经济增长,在一定范围内将会缩小区域经济差距;④加大对边缘区运输条件的改善力度将会降低异质性企业迁移门槛、提高核心区企业份额和边缘区经济增长速度,进而缩小区域经济差距.研究结果有助于科学制定区域交通政策.

The influence of transport costs and heterogeneous enterprise migration on regional balanced development—Analysis based on the theory of integration on spatial agglomeration and endogenous growth

With the transformation of the main contradiction in our society, how to explain the dynamic growth of economic activity in spatial dimension and time dimension has become an important theoretical issue. Based on the theory of integration on spatial agglomeration and endogenous growth, this article bring in the mechanism of endogenous dynamic of transport costs affect heterogeneous enterprise migration, and establish a agglomeration and growth integration model for the analysis of regional traffic policies affecting enterprise spatial location selection and regional balanced development. The study found that:① Better transport conditions between two areas will raise the threshold for the heterogeneous enterprise migration, reduce the enterprise share of the core areas, and will be good for economic growth of the backward areas and reduce the regional economic gap. ② Better transport conditions in core areas will reduce the threshold for the heterogeneous enterprise migration, increase the enterprise share of the core areas and the rate of the economic growth of both two areas, but expand the two regional economic gap at the same time. ③ Better transport conditions in backward areas will also reduce the threshold for the heterogeneous enterprise migration, increase the enterprise share of the core areas, but will be good for economic growth of the backward areas and reduce the regional economic gap within a certain range. ④ Increasing the strength of transport conditions in backward areas will reduce the threshold for the heterogeneous enterprise migration, increase the enterprise share of the core areas, and will be good for economic growth of the backward areas and reduce the regional economic gap. The results can provide a theoretical reference for the scientific formulation of regional transport policy.
