摘要:为分析山东省综合交通优势度与科技创新产业间的耦合协调关系,基于多源数据,梳理交通枢纽点、线、面特性及综合运输能力,构建综合交通优势度模型;基于政府支出、产业规模、创新产出3要素构建科技创新产业集聚度模型,定量分析山东省16个地级市的综合交通优势度与科技创新产业集聚度的空间分布格局、耦合协调水平和关联影响因素。结果表明:山东各地级市的综合交通优势度与科技创新产业集聚度有明显的空间分布差异,呈以青岛-济南为双核心的散射状空间发展格局;二者的协调水平有明显的空间相关性,存在显著的集聚模式;胶东经济圈、省会经济圈、鲁南经济圈的综合交通优势度与科技创新产业集聚度呈梯度下降式分布;构建多元化的交通网络系统可有效促进区域多式联运,政府支持率是区域科技创新产业规模和产出的直接影响因素;交通优势度与科技创新产业存在明显的正向影响关系,航空运输对科技创新产业的影响最显著;交通建设与科技产业的发展相互促进,交通发展吸引科技创新产业集聚,科技创新产业发展促使交通延伸,二者发展一致,达到高度协调时,产生空间溢出效应,带动周围地区社会经济发展,形成区域一体化的协调发展空间格局。

Abstract: 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.
