The Study of Territorial Division of Auto Industry Value Chain in Beijing
以北京为例，将汽车产业价值链分为六个环节，分析其利润分布和空间布局特征，发现利润呈倒U形和波浪形曲线，不同环节的集聚与分散程度不同，市场、政府和产业关联是主要影响因素。
The paper took Beijing as an example,which was the most promising core city in northern China in the development of auto industry.According to the producing process and the availability of data,the auto industry value chain was divided into six parts,namely the parts manufacturing( PM),the core parts manufacturing( CPM),the vehicle body and trailer manufacturing( VBTM),the complete vehicle manufacturing( CVM),the re-assembled vehicle manufacturing( RVM) and vehicle repair( VR).Using spatial analysis,niche width and cluster analysis analyzed the characteristics and the main factors of territorial division of auto industry value chain in Beijing.The study found that:( 1) The value distribution of Beijing auto industry value chain indexed by average profit and profit margin fitted symmetrical invertedUshape and waveshaped curve.( 2) The spatial distribution of CVM part and RVM part were agglomerated.However,PM part,CPM part and VBTM part were scattered.( 3) The phenomenon of coupling PM part and CPM part,RVM part and VR part exhibited higher similarity.( 4) The main factors that influenced the spatial distribution were market orientation,government control,industry linkages.
