Research On The Spatial Distribution Characteristics And Influencing Factors Of Urban Innovation In Jinan

In the era of knowledge economy,innovation has become the first driving force for global social and economic development.As an important node of the innovation community,the city also forms a complex innovation space within it while participating in regional innovation activities.With the aggregation and diffusion of innovation in cities,innovation-led driving factors are having a huge impact on the way urban space is used and the form of urban space.How to scientifically guide the orderly development of urban innovation space has become an important proposition for cities in the new era.In this context,it is of great significance to choose urban innovation space as the research object.On the basis of theoretical research,based on the data of invention patent application,and with the help of Gini coefficient,concentration rate,primacy,kernel density analysis and spatial autocorrelation analysis,this thesis finely depicts the innovation development level and spatial evolution characteristics of Jinan City from the three levels of "whole-subject-aggregation area " in the central urban area of Jinan;From the two dimensions of innovation resource background and urban development environment,this thesis adopts the analysis method of combining qualitative analysis and quantitative analysis to explore the influencing factors of innovation spatial distribution and analyze the spatial selection preferences of different innovation subjects?Through the research,it is found that:(1)The whole innovation scale of the central urban area of Jinan continues to expand,but the spatial difference of innovation activities is significant,and there is obvious spatial aggregation,forming an innovation pattern of "one axis,two cores and multiple nodes";(2)There are obvious differences in the growth rate of innovation activities among different subjects,and enterprises and colleges and universities gradually dominate the innovation scale;The four types of innovation activities have strong spatial imbalance,and the agglomeration of personal innovation space is the strongest,but the spatial distribution of the four types of innovation activities is different;(3)The innovation aggregation area is obviously graded,forming a typical "circle periphery" distribution feature;The innovation agglomeration area is dominated by the agglomeration of a single type of innovation subject,and the spatial organization,land composition and location selection of different types of innovation agglomeration areas are different;(4)Social and economic development,government policies,urban spatial structure and main roads jointly affect the improvement of the overall innovation level of the city and promote the agglomeration and diffusion of innovation space.Among them,the main urban transportation roads can guide the development of multi polarization diffusion of innovation activities.Innovation elements and innovation facilities have a significant positive impact on the spatial distribution of innovation activities.There are obvious differences in the spatial selection preferences of different innovation subjects,and financial and insurance institutions have a greater impact on the spatial layout of innovation activities.Through the self-made Python code to obtain a large number of invention patent application data,and use the GIS to accurately locate the applied invention patent,so as to analyze the spatial distribution characteristics of urban innovation activities from the micro scale "point" level,which is the biggest innovation of this thesis.Based on the analysis of the influencing factors of innovation background and urban environment,it also has a great reference for the relevant research on the law of urban innovation space in the future.However,the evolution mechanism of urban innovation space is complex.In the future,we should conduct in-depth research on the principles by means of in-depth interviews and case comparison...
