Economic-theory-based analysis of the collection standard of mine land reclamation bond and its calculation approach

The collection standard of mine land reclamation bond based on the ʹrational economic manʹ theory is analyzed. There are three relations between the collection standard of the bond and the expected reclamation cost. Under each of the three relations, the choices and welfare levels of the regulatory authorities and the mining enterprises are analyzed respectively. It is indicated that the proper amount of the bond should equal to the reclamation cost. There are two approaches to calculate reclamation cost. One is based on ecosystem service value. The other is based on reclamation fee. The former is difficult to operate in practice for the result derived by this method has much difference from the payment ability of the mining enterprises. By comparison, it is easy to operate in practice to calculate reclamation cost through the calculation of the total sum of engineering reclamation fee, biological reclamation fee and other reclamation fee. Therefore, the approach of calculating reclamation cost based on reclamation fee should be adopted to calculate the amount of the bond the mine enterprises should submit.
