【摘要】：以复杂网络描述产业间技术扩散,基于概率论和网络技术设计产业技术流网络建模与结构效应分析方法,提出产业技术流网络(ITFN)概念及其随机、动态、多层和复杂性特征。改进Weaver指数,根据产业产品与流程创新二维随机变量联合概率分布确定产业节点连接规则,构建垂直型ITFN,测度产业间技术共同度,构建水平型ITFN。以ITFN度分布与度相关揭示产业技术扩散结构整体与动态效应,以中心-外围分层网络、产业技术流树展现产业结构升级动力效应,以中心度测度产业技术流吸收、溢出与中介个体效应,以中国工业产业技术扩散系统为实例进行有效性验证。
[Abstract]:Based on probability theory and network technology design, the concept of industrial technology flow network (ITFN) and its randomness are proposed by using complex networks to describe the diffusion of technology among industries, and based on probability theory and network technology design, the industrial technology flow network modeling and structure effect analysis method are proposed. Dynamic, multi-layer and complexity characteristics. Improved Weaver index, according to the two-dimensional random variables joint probability distribution of industrial product and process innovation to determine the rules of industrial node connection, and construct vertical ITFN. Measure the technical commonality between industries, construct horizontal ITFN, reveal the whole and dynamic effects of industrial technology diffusion structure by ITFN degree distribution and degree correlation, and take the center-peripheral stratified network. The industrial technology flow tree shows the dynamic effect of industrial structure upgrading, and measures the absorption, spillover and intermediary individual effects of industrial technology flow with the centrality, and takes the Chinese industrial technology diffusion system as an example to verify the effectiveness.
