基于新经济地理学的研究方法,构建模型研究了偏在性自然资源对非资源型制造业区位选择行为和城市区位特征的影响机理。研究发现,当资源型制造业的规模较小、自然资源的位置较为偏僻、资源型制造业产品的运输成本较小时,城市—工矿区模式将成为区域空间结构的均衡状态;当资源型制造业的规模较大、自然资源的位置靠近区域的中心、资源型制造业产品的运输成本较高时,资源型城市是均衡状态。研究还表明,自然资源对城市区位的影响受控于偶然因素和路径依赖效应。接着基于研究成果完善了陆大道先生提出的大河发展轴的区位条件和经济机理的解释。最后进行了总结并对区域开发实践提出了建议。

Based on the methods of new economic geography,a spatial model is built to explore the effects of natural resources on non-resource-based manufacturing location choice behavior and thus characteristics of urban location.The results show that,when the resources-based manufacturing is small,the location of natural resources is remote,and the transportation costs of resources-based manufactured goods are small,the mode of city-industrial and mining areas will be the equilibrium state of regional spatial structure.When the resources-based manufacturing has a large scale,the natural resources located near the center of the region,the resources-based manufactured goods are characterized by high transport costs,resources-based city becomes an equilibrium state.The study also shows that circular causation of demand and path dependent effects play an important role in natural resources shaping urban location.Then,based on the research,the economic mechanisms of big river development axis proposed by Mr.Lu Dadao are completed.Finally,the paper is concluded and recommendations on China’s regional practice are suggested.
