研究主导部门在经济起飞中的作用时,罗斯托(Rostow)使用旁侧效应表示主导部门的变动所引起的周围一系列变化。由于缺乏可计算的方法,对旁侧效应的研究多为定性描述。本文在产业网络的基础上,根据旁侧效应的内涵提出协同型和竞争型旁侧关联的概念,构建了两类产业旁侧关联网络模型,进一步分析了四种旁侧效应。计算实例表明,产业旁侧关联网络可以描述产业部门之间的旁侧关联,表明活动过程中行为主体之间的关联关系和区域经济的结构特征,为分析旁侧效应提供了方法,也为研究关键产业、产业集群和制定区域非均衡发展战略等问题提供了定量化的依据。
In the course of studying the roles of the leading sectors in economic take-off, Rostow used side effects to represent various changes in the surrounding caused by the varying of leading sectors. However, due to lacking of feasible technologies, the studies on side effects are often qualitative. On the basis of in- dustry networks, the concepts of synergy and competition side linkages are proposed in this paper accord- ing to the meanings of side effects, two types of networks are constructed, and the four types of side effects are analyzed. Exemplification indicates that industry side linkage networks can describe side linka- ges among industry sectors, relationships among behavioral agents and structural features of economies. They can provide quantitative references for analyzing side effects, studying the key sectors and industry clusters or generating disequilibrium strategy etc.
