市场邻近、供给邻近与中国制造业空间分布--基于中国省区间投入产出模型的分析

Market Access,Supply Access and Spatial Distribution of Industries in China:Based on China Inter-Provincial Input-Output Analysis

探究制造业空间分布的成因和机理是深入理解我国区域差异成因的基础。NEG理论认为由市场邻近和供给邻近所决定的贸易成本是制造业地理集中的主导因素之一。本文利用2002年中国省区间投入产出模型,计算了分省区两位码分类制造业部门的市场邻近与供给邻近,在区分部门特性和区域属性影响的基础上,验证了贸易成本及其他要素对制造业部门空间分布的影响。在现阶段的生产成本水平下,贸易成本是影响我国制造业部门空间分布的重要因素。

s Understanding the mechanism of manufacturing agglomeration is vital for explaining regional inequality in China.Based on NEG theory,trade cost,which is decided by market access and supply access,is one of the main forces which may induce manufacturing agglomeration.Based on China inter-provincial input-output model 2002（China IRIO 2002）,this paper calculated market access and supply access of Chinese provinces at sector level.By taking both of the regional characteristics and industrial attributes into account,we explored the effects of trade cost and other factors on manufacturing agglomeration.Results showed that under current level of producing costs,trade cost is vital in determining the spatial distribution of manufacturing sectors in China.
