多式交通对高技术产业集聚的溢出效应实证分析

为促进立体多式交通在中国的生态集约效应及红利共享效应增长，推进新时代区域经济高质量协调发展，将高技术产业集聚的空间溢出效应与多式交通相结合，基于新经济地理学，采用熵值法、空间杜宾模型，利用中国30个省份2005—2018年相关数据，综合分析公路、铁路、航空3类主要交通方式对区域高技术产业集聚的空间溢出效应及逻辑路径。结果表明：高技术产业集聚水平存在显著的空间依赖性，相邻省域高技术产业集聚存在正向溢出；3种交通方式对高技术产业空间集聚均有显著正向溢出效应但存在差异，对于高技术产业集聚度高的省份，与其位置相邻、经济条件相似的省份获得其溢出效应主要通过公路运输，航空或铁路运输次之，而与其位置相邻、技术条件相似的省份则主要通过铁路运输，次之为航空运输，最后才是公路运输。据此提出建构并完善多式联运交通网络、有先后空间时序地建设不同交通、提升高技术产业发展的区域整体效应等对策建议。

The Spatial Effect of Multimodal Transportation on High-tech Industry Agglomeration

Based on the national conditions of Large geographical population and the strategic requirements for the coordinated development of high-tech industry among regions under the internal economic cycle, this paper chooses the Dubin model to measure the spillover effects of railway, highway, and aviation on high-tech industry agglomeration and its path realization logic. The conclusion shows that: the development level of high-tech industry agglomeration has significant spatial dependence, and there is a positive spillover effect on the high-tech industry agglomeration development of neighboring provinces; the three transportation have significant positive spillover effects on the high-tech industry agglomeration; different transportation have different paths to realize the spillover effect on high-tech industries. Accordingly, corresponding countermeasures and suggestions are put forward.
