Industrial chains exhibit strong interdependency within a large-scale resource-based enterprise group. When analyzing the independency effect in industrial chains, the interdependency of financial index is often ignored. In this paper, we will mainly focus on measuring the long-term interdependency effect by 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 independency analysis among the industrial chains. The results show that high degree of independency appears in production costs and marketing costs, and low degree appears in revenues and profits.
