Spatial interaction between comprehensive transportation advantage and science and technology innovation industry based on multi-source data
In order to analyze the coupling and coordination relationship between the comprehensive transportation advantage and the aggregation degree of the science and technology innovation industry in Shandong Province,based on multi-source data,the characteristics of transportation hubs,lines,and surfaces and comprehensive transportation capacity are sorted out,and a comprehensive transportation advantage model is constructed;based on the three elements of government expenditure,industrial scale,and innovation output,a aggregation degree of the science and technology innovation industry model is constructed to quantitatively analyze the spatial distribution pattern,coupling coordination level,and related influencing factors of the comprehensive transportation advantage and the aggregation degree of the science and technology innovation industry in 16 prefecture-level cities in Shandong Province.The results show that there is a significant spatial distribution difference in the comprehensive transportation advantage and the aggregation degree of the science and technology innovation industry among the prefecture-level cities in Shandong Province,displaying a scattered spatial development pattern with Qingdao-Jinan as the dual core;there is a clear spatial correlation in the coordination level of the two,with a significant aggregation pattern;the comprehensive transportation advantage and the aggregation degree of the science and technology innovation industry in the Jiaodong economic zone,the Provincial Capital economic zone,and the Southern Shandong economic zone show a gradient distribution;building a diversified transportation network system can effectively promote regional multimodal transport,with government support being a direct influencing factor on the scale and output of regional science and technology innovation industries;there is a clear positive relationship between transportation advantage and the science and technology innovation industry,with air transport having the most significant impact on the science and technology innovation industry;transportation construction and the development of the technology industry mutually promote each other,with transportation development attracting the aggregation of science and technology innovation industry,and the development of science and technology innovation industry promoting the extension of transportation,where both developments are consistent;when reaching a high level of coordination,spatial spillover effects are produced,driving the socio-economic development of surrounding areas and forming a coordinated development spatial pattern of regional integration.
