Study on the Dynamic Input-Output Model with Coal Mine Safety

The dynamic input-output model with coal mine safety was established on the basis of the table of coal mine input-output with safety in this paper. And this paper gives definitions and proposes methods to make sure the investment coefficient of coal mine productive, investment coefficient of coal mine security, and consumption coefficient of accident. The dynamic input-output model with coal mine safety can be solved with reverse recursive solution, and be applied in analysis of input-output for coal mine safety and forecast of safety input.
