中国互联网产业空间演化格局及其创新效应研究

Research on spatial Evolution pattern and Innovation Effect of Chinese Internet Industry

摘要:

摘 要：基于2007—2017年互联网及其区域创新数据，运用引力模型、网络分析、重心模型和空间计量模型等方法探讨了中国省域互联网产业的空间演化特征及其创新效应。结果表明：省域互联网发展水平提升较为明显，但地理分布具有自东向西呈阶梯状分布特点，同时冷热点呈现出“极核化”的发展趋势，热点区域主要集中于江浙沪地区；中国的互联网空间结构逐渐由简单线性结构变为更为复杂的空间网络结构，各个地区之间的互联网空间联系越来越紧密，互联网空间联系总量的重心坐标呈现出自北向南，由东到西的“W型”漂移特征；区域创新水平在省份间也展现出非随机的空间聚集效应，在互联网经济的推动下区域创新能力逐渐增强，R&D人员全时当量、政府供给导向均对区域创新都有显著正向影响。

Abstract：Based on the Internet and its regional innovation data from 2007 to 2017, this paper discusses the spatial evolution characteristics and innovation effects of the Internet industry in China's provincial regions by using gravity model, network analysis, gravity center model and spatial econometric model. The results show that: The development level of the provincial Internet is improved significantly, but the geographical distribution shows a step-like distribution from east to west. Meanwhile, the cold hot spots show the development trend of “focusing”, and the hot spots are mainly concentrated in Jiangsu, Zhejiang and Shanghai; China's Internet space structure gradually from a simple linear structure to a more complex spatial network structure, the Internet space between each region is getting closer and closer, the center of gravity coordinates of the total Internet space links from north to south, from east to west “W-shaped” drift characteristics; Regional innovation level also shows a non-random spatial clustering effect among provinces. Under the promotion of the Internet economy, regional innovation ability is gradually strengthened. Full-time equivalent of R&D personnel and government supply orientation have a significant positive impact on regional innovation.
