Research On Evolution Of Spatial Distribution And Influencing Factors Of Manufacturing Industry In Beijing-Tianjin-Hebei Region

Studying the evolution characteristics of the spatial distribution of manufacturing industry in Beijing-Tianjin-Hebei region is of great significance under the background of building China into a manufacturing power.On the basis of relevant research,this paper measured the agglomeration level and specialization level from 2007 to 2019 by selecting the location gini coefficient and location quotient.Besides,the spatial standard deviation ellipse method is used to visually analyze the spatial process of manufacturing distribution.The spatial Dubin model is used to empirically test the impact of various factors on the distribution of manufacturing industry.The research results indicate that:(1)In terms of time evolution,the agglomeration level of manufacturing industry showed the characteristics of rising first and falling later from 2007 to 2019.The agglomeration level in three different type of manufacturing industries remained stable.There are Specialization advantages for labor-intensive manufacturing and capital-intensive manufacturing in Hebei Province,while there are specialization advantages for technology-intensive manufacturing in Beijing and Tianjin.(2)In terms of spatial evolution,from 2007 to 2019,the manufacturing industry moved to Tianjin and Hebei from Beijing;The labor-intensive manufacturing expanded to the central southern areas of Hebei Province;The capital-intensive manufacturing moved to the eastern Bohai rim region;The technology-intensive manufacturing moved to the southern areas around Beijing and Tianjin.(3)The results showed that the labor cost negatively affects the distribution of manufacturing industry,indicating that the manufacturing industry in the three regions has not got rid of relying on cheap labor.The fixed asset investments,transportation conditions,market scale and opening-up level positively affect the distribution of manufacturing industry.There is no significant impact of government support,showing that the internal coordination in the three regions needs to be further improved.Based on the conclusions,Beijing,Tianjin and Hebei should accurately capture the industry features and take the lead in breaking key fields in the future;A reasonable pattern of labor division should be established according to regional differences;The construction of factor integration should be accelerated to promote the integrated development of manufacturing industry and technological innovation.
