我国省际高技术产业同构性的网络结构特征研究

Research on the Characteristics of Network Structure of Isomorphism in China′s High-tech Industry

基于2007-2016年我国省际高技术产业数据,利用社会网络分析法,研究我国高技术产业同构性的网络特征。研究发现:第一,我国高技术产业结构存在网络同构性,网络密度和网络关联系数呈现波动上升,网络紧密性有所增加,网络等级度和网络效率下降,网络结构仍处在不稳定状态。第二,重要“行动者”在网络结构中的控制程度弱化;山西、内蒙古及浙江等地区分别作为中西部和东部地区高技术产业结构变动的“主导者”;北京、天津、广东等经济较发达地区远离高技术产业同构性网络中心。第三,网络中省份可以划分为四类凝集子群,即东部经济发达地区、中西部及部分东部欠发达地区、西部经济欠发达地区。最优产业结构网络构建,需要从“全国一盘棋”思维出发,精准把握高技术产业结构调控重点省份,完善省域间利益协调机制。

Based on the data of high-tech industry of China′s provinces from 2007 to 2016,the social network analysis method is used to study the network characteristics of China′s high-tech industry isomorphism.The research finds out:First,there is network isomorphism in China′s high-tech industrial structure.The network density and associations are fluctuating upward;the network tightness is increased;the network hierarchy and efficiency are declining;the network structure is still in an unstable state.Second,the dominating function of important"actors"in the network structure is weakened;Shanxi,Inner Mongolia and Zhejiang provinces are the"leaders"leading the changes in the high-tech industrial structure in the central,western and eastern regions respectively.The more economically developed provinces such as Beijing,Tianjin and Guangdong are far from the network centers of high-tech industry isomorphism.Third,the provinces in the network can be divided into four types of agglomeration subgroups,that is,the economically developed regions in the East,the underdeveloped regions in the central,western,and some of the eastern regions,and the economically underdeveloped regions in the West.In order to build the optimal industrial structure network,China needs to start from the thinking of"considering the whole country as one",accurately identify the key provinces in regulating high-tech industrial structure,and improve the coordination mechanism of interests between regions.
