Measuring Interdependency in Industrial Symbiosis Network with Financial Data

摘要

Industrial chains exhibit strong interdependency within industrial symbiosis network. When analyzing the interdependency effect among industrial chains, however, financial index is often ignored. In this paper, we will mainly focus on measuring the long-term interdependency effect through historical simulation and cointegration tests with financial data. A large-scale coal-mining group is studied empirically as a case to explain the framework of interdependency analysis among the industrial chains. The results display high degree of interdependency between production costs and marketing costs, and low degree of that between revenues and profits, which means high controllability of material flows within IS network and low controllability of sales, marketing.
