Modeling and implication of coal physical input-output table in China-Based on clean coal concept

In China, coal is not only the main fuel but also the majority substance causing pollution. For the purpose of monitoring and scenario analysis, this paper presents a coal physical input-output table (CPIOT) that shows the complete coal flow in the production system based on clean coal concept. We first depict the material flow of coal in China and construct a theoretical table of CPIOT to describe coal mining, consumption, emission, reuse and recycle, and then, four kinds of coal classification and sixteen sectors are declared for empirical analysis. By data collection, processing and calibration, this paper finally builds a CPIOT in 2012 which can observe the coal industry in detail. Furthermore, we apply it to assess circuits, material recycling and coal reduction effect and find a lot of interesting results, which proves the wide application and huge values of CPIOT in the analysis of China's coal industry.
