重庆市新能源汽车产业空间演化特征及影响因素研究

Study on Spatial Evolution Characteristics and Influential Mechanism of New Energy Vehicle Industry in Chongqing

本文运用重庆市新能源汽车16228条企业层面数据,考察其不同环节的空间分布格局和演化特征,探究了影响企业区位选择行为的关键因素.研究结果表明:①2016-2021年一般零部件企业主副中心聚集差距缩小,核心零部件企业由中心城区向主城新区外溢,基于企业规模和类型权重描绘了各环节热点区域,发现零部件企业密集区域与热点区域不一致.②重庆市新能源汽车产业整—零配套布局分散,各环节分异特征明显.③在不考虑经济水平和劳动市场作用条件下,新能源汽车、传统汽车整车制造企业数量对核心零部件企业布局分别起正向和负向作用;路网密度、开发区数量、城市化进程对新能源汽车各环节企业布局均有积极影响.

Using 16228 enterprise level data of Chongqing new energy vehicles,this paper investigates the spatial distribution pattern and evolution characteristics of different links,and explores the key factors affecting the location choice behavior of enterprises.The research conclusions show that:①The aggregation gap between the main and sub-centers of general parts enterprises narrowed from 2016 to 2021,and the core parts enterprises overflowed from the central urban area to the new area of the main city.Base on the weight of enterprise scale and type,it was found that the dense areas of parts enterprises were inconsistent with the hot areas.②The layout of whole-zero supporting of the Chongqing's new energy vehicle industry is scattered,and the differentiation characteristics of each link is obvious.③Without considering the economic level and labor market conditions,the number of new energy vehicle and traditional vehicle manufacturing enterprises plays a positive and negative significant role in the layout of core parts enterprises respectively.The density of road network,the number of development zones and the process of urbanization have a positive impact on the layout of enterprises in all links of new energy vehicles.
