基于细分行业的安徽省创新型企业集聚研究

As an important force in shaping the pattern of innovative geography, the external characteristics and internal mechanisms of the spatial distribution of innovative enterprises need to be studied in depth. Firstly, we screened, classified and built spatial database for innovative enterprises in Anhui Province; Then we applied kernel density estimation and geographical detector methods as well as the aided of ArcGIS, this paper systematically discussed the spatial agglomeration patterns and agglomeration factors of innovative enterprises. The results are as follows: (1) The main types of innovative enterprises in Anhui province are those of advanced manufacturing and automation, then biology and new medicine, new material and electronic information industries also own a large scale. (2)The spatial distribution of innovative enterprises is significantly unbalanced, showing the spatial distribution characteristics of "one core, one belt and multiple nodes", and Hefei and Wuhu are two important agglomeration areas. Different types of innovative enterprises are diversified in distribution, which include four patterns, namely point-axis, polar-core, dual-core and multi-core decentralization. (3)Innovative factors mean a lot for the spatial agglomeration of innovative enterprises, while traditional factors and policy-oriented factors also really matters. Above all, industrial foundation, human capital and innovation investment are three foremost influencing factors, whereas the influencing factors of innovative enterprises in different industries show some heterogeneous characteristics.
