Evolutionary Characteristics of Agglomeration of New High-tech Enterprises in China
This paper selects 218300 new high-tech enterprises in China from 2010 to 2019 as samples,uses kernel density and other methods to describe their spatiotemporal evolution characteristics,and uses the MGWR model to explore the influencing factors of new high-tech agglomeration.The results show that:1)From 2010 to 2019,the overall distribution of new high-tech enterprises in China showed the characteristics of"dense in the east of China and sparse in the west of China,more in the south of China and less in the north of China",and gradually spread to the central and western regions,and their agglomeration centers changed from"three cores"to"three poles and multiple cores".2)The new high-tech enterprises mainly come from the four major industries,and the agglomeration characteristics of the industries are obviously different,and the regional imbalance generally shows a trend of first increasing and then decreasing,but there are stages of agglomeration between industries.3)The number of authorized invention patents,scientific research expenditure in the general budget of local finance,the number of on-the-job employees,the output value of the manufacturing sector,the proportion of construction land,the density of the road network in the built-up area,and the per capita GDP jointly act on the agglomeration of high-tech enterprises,and the impact intensity decreases in turn.Among them,the spatial scale of innovative technology output and infrastructure construction,represented by the number of authorized invention patents and the density of the road network in built-up areas,is small and has strong spatial heterogeneity.Finally,some policy suggestions are put forward based on the research conclusions.
