Research On The Oil And Gas Resource Tax Rate Based On The Maximization Of Social Welfare

In recent years,Chinese oil and gas resources tax reform continuously,on November 1,2011,the tax rate about our oil and gas resources is 5%,on December 1,2014,incorporate the mineral resources compensation tax,but compared with foreign countries which oil and gas industry is mature,our country's current oil and gas resources tax and fee is low,the oil and gas resources development path deviates from the social whole maximization welfare,mainly embodied in top oil prices during the vigorous development,has deliberately cut production during a drop in oil prices.It is because of the oil and gas resource tax not well adjust resource development path,causing the social welfare loss.Reasonable tax can regulate the resource of oil and gas to optimal production,the optimal production decisions can balance the interest of present and later generations and can also promote the efficient allocation of the resource.From the perspective of optimal allocation of mineral resource,build decision-making models to promote oil and gas resource to maximize social welfare and company profits,and through the optimal control method,under the condition of resource sustainable decisions to maximize social welfare,to study three different forms of oil and gas resource tax.The study found:(1)Ad valorem tax,the optimal ad valorem tax rate is 26.4 %,the government not only can guarantee the maximization of social welfare,but also can get a lot of tax revenue;(2)Production tax,the amount of the tax rate is 1.77 ? per ton,the government can ensure the maximization of social welfare,but less government tax revenue;(3)Reserve tax,reserve tax rate under welfare maximization is-0.13 ? per ton,which is showing that the government need to subsidize companies,although they can ensure the maximization of social welfare,it will put on the financial pressure.Three different forms of taxation regulation are able to maximize resources development and the social welfare,but the conditions of use are different.In the current oil and gas resources development degree of marketization is not high,the government to the dominant ecological destruction and resource depletion cost,AD valorem tax could be implemented,but with the future resources externality internalization of enterprise bear the cost of more and more,to ensure that resources enterprise has abundant funds to governance the resources and environment negative externalities.
