Abstract:

This study measures the spatial correlation network matrix of ‘Internet plus’ based on the revised gravity model, and explores the structural characteristics of spatial correlation network of China’s (excluding Tibet, Hong Kong, Macao and Taiwan) ‘Internet plus’ development through social network analysis methods. We also examine the status, role, type and role of each province (region) in the network, and reveal the influencing factors of spatial correlation network by utilizing the QAP method. The conclusions are as follows: 1) In terms of the overall network characteristics, the degree of interprovincial ‘Internet plus’ connectivity has increased considerably, and the network density has shown a certain degree of expansion. Although the network density presents the increasing trends, the interprovincial ‘Internet plus’ spatial correlation network is not high enough, which needs to be further improved. 2) As far as the network centrality, Beijing and Shanghai are located in the core of the ‘Internet plus’ spatial correlation network, these cities are two major engines promoting the development of ‘Internet plus’. Meanwhile, the role of Guangdong and Jiangsu in the ‘Internet plus’ spatial correlation network has begun to highlight, and gradually moving towards the core area, which is expected to play the central actor role in the ‘Internet plus’ spatial correlation network. And accelerating its internal connections with surrounding areas by virtue of its high efficiency of resource flow and resource acquisition. 3) China’s ‘Internet plus’ development can be divided into four sectors. There exist little changes among these four sectors, only Jiangsu, Fujian, Inner Mongolia, Liaoning and Guangxi have changed during the sample period. In 2016, the first plate includes Beijing, Tianjin, Shanghai, Guangdong and Jiangsu, which belongs to typical ‘net spillover’ type; the second plate covers Zhejiang, Shandong and Fujian, which belonged to a typical ‘broker’ type; The third plate includes Hebei, Hainan, Shanxi, Jilin, Heilongjiang, Anhui and other 16 regions, which belonged to a typical ‘main benefit’, and the fourth plate involves Inner Mongolia, Liaoning, Jiangxi, Henan, Hubei and Guangxi, which belong to the typical ‘two-way spillover’ plate. 4) A complete closed circuit is formed among these four plates. The first plate takes the role of the first radiation center in the network, and presents strong spillover effect on the provinces belong to other three plates. The second plate acts the role of second radiation centers and intermediary bridges, which not only exhibits spillover effects on the third and fourth plates, but also transfers the spillover effects of the first plate to the third and fourth plates. The third plate plays the role of receiver, which receives the spillover effect from the first and second plates. The fourth plate plays a pivotal role in the network, which presents the two-way feedback relationship with the first and second plates. 5) Technological innovation, infrastructure, human capital, market development and opening-up all present positive effects on the spatial correlation network of ‘Internet plus’ development. Especially, China’s ‘Internet plus’ spatial correlation network is inhibited by spatial geographical distance, and the knowledge overflow and flow effect of the ‘Internet plus’ would gradually decrease with the increasing geographic distance.
